Definitions

  • RAS-family proteins including KRAS (V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog), NRAS (neuroblastoma RAS viral oncogene homolog) and HRAS (Harvey murine sarcoma virus oncogene) and any mutants thereof are small GTPases that exist in cells in either GTP-bound or GDP-bound states (McCormick et al., J. Mol. Med. (Berl), 2016, 94(3):253-8; Nimnual et al., Sci. STKE., 2002, 2002(145):pl36).
  • the RAS-family proteins have a weak intrinsic GTPase activity and slow nucleotide exchange rates (Hunter et al., Mol. Cancer Res., 2015, 13(9): 1325-35). Binding of GTPase activating proteins (GAPs) such as NF1 increases the GTPase activity of RAS-family proteins.
  • GAPs GTPase activating proteins
  • NF1 NF1
  • GEFs guanine nucleotide exchange factors
  • RAS- family proteins When in the GTP-bound state, RAS- family proteins are active and engage effector proteins including RAF and phosphoinositide 3-kinase (PI3K) to promote the RAF/mitogen or extracellular signal- regulated kinases (MEK/ERK).
  • PI3K phosphoinositide 3-kinase
  • MEK/ERK extracellular signal- regulated kinases
  • SOS1 is critically involved in the activation of RAS-family protein signaling in cancer via mechanisms other than mutations in RAS-family proteins.
  • SOS1 interacts with the adaptor protein Grb2 and the resulting SOS1/Grb2 complex binds to activated/phosphorylated Receptor Tyrosine Kinases (e.g., EGFR, ErbB2, ErbB3, ErbB4, PDGFR-A/B, FGFR1/2/3, IGF1 R, INSR, ALK, ROS, TrkA, TrkB, TrkC, RET, c-MET, VEGFR1/2/3, AXL) (Pierre et al., Biochem. Pharmacol., 2011, 82(9): 1049-56).
  • activated/phosphorylated Receptor Tyrosine Kinases e.g., EGFR, ErbB2, ErbB3, ErbB4, PDGFR-A/B, FGFR1/2/3, IGF1 R, INSR, ALK, ROS, TrkA, TrkB, TrkC, RET, c-MET, VEGFR1/2/3, AXL
  • SOS1 is also recruited to other phosphorylated cell surface receptors such as the T cell Receptor (TCR), B cell Receptor (BCR) and monocyte colony-stimulating factor receptor (Salojin et al., J. Biol. Chem.2000, 275(8):5966-75).
  • TCR T cell Receptor
  • BCR B cell Receptor
  • monocyte colony-stimulating factor receptor Salojin et al., J. Biol. Chem.2000, 275(8):5966-75.
  • SOS1-activation of RAS-family proteins can also be mediated by the interaction of SOS1/Grb2 with the BCR-ABL oncoprotein commonly found in chronic myelogenous leukemia (Kardinal et al., 2001, Blood, 98:1773-81; Sini et al., Nat. Cell Biol., 2004, 6(3):268-74). Furthermore, alterations in SOS1 have been implicated in cancer.
  • SOS1 mutations are found in embryonal rhabdomyosarcomas, Sertoli cell testis tumors, granular cell tumors of the skin (Denayer et al., Genes Chromosomes Cancer, 2010, 49(3):242-52) and lung adenocarcinoma (Cancer Genome Atlas Research Network., Nature, 2014, 511 (7511):543-50). Meanwhile over-expression of SOS1 has been described in bladder cancer (Watanabe et al., IUBMB Life, 2000, 49(4):317-20) and prostate cancer (Timofeeva et al., Int. J. Oncol., 2009; 35(4):751-60).
  • hereditary SOS1 mutations are implicated in the pathogenesis of RASopathies like e.g., Noonan syndrome (NS), cardio-facio-cutaneous syndrome (CFC) and hereditary gingival fibromatosis type 1 (Pierre et al., Biochem. Pharmacol., 2011, 82(9):1049-56).
  • SOS1 is also a GEF for the activation of the GTPases RAC1 (Ras-related C3 botulinum toxin substrate 1) (Innocenti et al., J. Cell Biol., 2002, 156(1):125-36).
  • RAC1 like RAS-family proteins, is implicated in the pathogenesis of a variety of human cancers and other diseases (Bid et al., Mol. Cancer Ther.2013, 12(10):1925-34).
  • SOS2 Son of Sevenless 2
  • SOS1 a homolog of SOS1 in mammalian cells, also acts as a GEF for the activation of RAS-family proteins (Pierre et al., Biochem. Pharmacol., 2011, 82(9): 1049-56; Buday et al., Biochim. Biophys. Acta., 2008, 1786(2):178-87).
  • SOS2 Son of Sevenless 2
  • SOS1/RAS-family protein driven cancers or other SOS1/RAS-family protein pathologies
  • SOS1/RAS-family protein pathologies or normal cells and tissues.
  • SOS1 inhibitor compounds are be expected to consequently inhibit signaling in cells downstream of RAS-family proteins (e.g., ERK phosphorylation).
  • SOS1 inhibitor compounds are be expected to deliver anti- cancer efficacy (e.g., inhibition of proliferation, survival, metastasis, etc.).
  • High potency towards inhibition of SOS1:RAS-family protein binding (nanomolar level IC50 values) and ERK phosphorylation in cells (nanomolar level IC50 values) are desirable characteristics for a SOS1 inhibitor compound.
  • a desirable characteristic of a SOS1 inhibitor compound would be the selective inhibition of SOS1 over SOS2. This conclusion is based on the viable phenotype of SOS1 knockout mice and lethality of SOS1/SOS2 double knockout mice, as described above.

Description

SOS1 INHIBITORS AND USES THEREOF CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of priority to U.S. Application Ser. No. 63/131,674, which was filed December 29, 2020, the disclosure of which is hereby incorporated by reference as if set forth in its entirety. FIELD OF THE DISCLOSURE [0002] The present disclosure relates to inhibitors of SOS1 useful in the treatment of diseases or disorders. Specifically, the present disclosure is concerned with compounds and compositions inhibiting SOS1, methods of treating diseases associated with SOS1, and methods of synthesizing these compounds. BACKGROUND OF THE DISCLOSURE [0003] RAS-family proteins including KRAS (V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog), NRAS (neuroblastoma RAS viral oncogene homolog) and HRAS (Harvey murine sarcoma virus oncogene) and any mutants thereof are small GTPases that exist in cells in either GTP-bound or GDP-bound states (McCormick et al., J. Mol. Med. (Berl), 2016, 94(3):253-8; Nimnual et al., Sci. STKE., 2002, 2002(145):pl36). The RAS-family proteins have a weak intrinsic GTPase activity and slow nucleotide exchange rates (Hunter et al., Mol. Cancer Res., 2015, 13(9): 1325-35). Binding of GTPase activating proteins (GAPs) such as NF1 increases the GTPase activity of RAS-family proteins. The binding of guanine nucleotide exchange factors (GEFs) such as SOS1 (Son of Sevenless 1) promote release of GDP from RAS-family proteins, enabling GTP binding (Chardin et al., Science, 1993, 260(5112):1338-43). When in the GTP-bound state, RAS- family proteins are active and engage effector proteins including RAF and phosphoinositide 3-kinase (PI3K) to promote the RAF/mitogen or extracellular signal- regulated kinases (MEK/ERK). Published data indicate a critical involvement of SOS1 in mutant KRAS activation and oncogenic signaling in cancer (Jeng et al., Nat. Commun., 2012, 3:1168). Depleting SOS1 levels decreased the proliferation rate and survival of tumor cells carrying a KRAS mutation whereas no effect was observed in KRAS wild type cell lines. The effect of loss of SOS1 could not be rescued by introduction of a catalytic site mutated SOS1, demonstrating the essential role of SOS1 GEF activity in KRAS mutant cancer cells. [0004] SOS1 is critically involved in the activation of RAS-family protein signaling in cancer via mechanisms other than mutations in RAS-family proteins. SOS1 interacts with the adaptor protein Grb2 and the resulting SOS1/Grb2 complex binds to activated/phosphorylated Receptor Tyrosine Kinases (e.g., EGFR, ErbB2, ErbB3, ErbB4, PDGFR-A/B, FGFR1/2/3, IGF1 R, INSR, ALK, ROS, TrkA, TrkB, TrkC, RET, c-MET, VEGFR1/2/3, AXL) (Pierre et al., Biochem. Pharmacol., 2011, 82(9): 1049-56). SOS1 is also recruited to other phosphorylated cell surface receptors such as the T cell Receptor (TCR), B cell Receptor (BCR) and monocyte colony-stimulating factor receptor (Salojin et al., J. Biol. Chem.2000, 275(8):5966-75). This localization of SOS1 to the plasma membrane, proximal to RAS-family proteins, enables SOS1 to promote RAS-family protein activation. SOS1-activation of RAS-family proteins can also be mediated by the interaction of SOS1/Grb2 with the BCR-ABL oncoprotein commonly found in chronic myelogenous leukemia (Kardinal et al., 2001, Blood, 98:1773-81; Sini et al., Nat. Cell Biol., 2004, 6(3):268-74). Furthermore, alterations in SOS1 have been implicated in cancer. SOS1 mutations are found in embryonal rhabdomyosarcomas, Sertoli cell testis tumors, granular cell tumors of the skin (Denayer et al., Genes Chromosomes Cancer, 2010, 49(3):242-52) and lung adenocarcinoma (Cancer Genome Atlas Research Network., Nature, 2014, 511 (7511):543-50). Meanwhile over-expression of SOS1 has been described in bladder cancer (Watanabe et al., IUBMB Life, 2000, 49(4):317-20) and prostate cancer (Timofeeva et al., Int. J. Oncol., 2009; 35(4):751-60). In addition to cancer, hereditary SOS1 mutations are implicated in the pathogenesis of RASopathies like e.g., Noonan syndrome (NS), cardio-facio-cutaneous syndrome (CFC) and hereditary gingival fibromatosis type 1 (Pierre et al., Biochem. Pharmacol., 2011, 82(9):1049-56). [0005] SOS1 is also a GEF for the activation of the GTPases RAC1 (Ras-related C3 botulinum toxin substrate 1) (Innocenti et al., J. Cell Biol., 2002, 156(1):125-36). RAC1, like RAS-family proteins, is implicated in the pathogenesis of a variety of human cancers and other diseases (Bid et al., Mol. Cancer Ther.2013, 12(10):1925-34). [0006] Son of Sevenless 2 (SOS2), a homolog of SOS1 in mammalian cells, also acts as a GEF for the activation of RAS-family proteins (Pierre et al., Biochem. Pharmacol., 2011, 82(9): 1049-56; Buday et al., Biochim. Biophys. Acta., 2008, 1786(2):178-87). Published data from mouse knockout models suggests a redundant role for SOS1 and SOS2 in homeostasis in the adult mouse. Whilst germline knockout of SOS1 in mice results in lethality during mid-embryonic gestation (Qian et al., EMBO J., 2000, 19(4):642-54), systemic conditional SOS1 knockout adult mice are viable (Baltanas et al., Mol. Cell. Biol., 2013, 33(22):4562-78). SOS2 gene targeting did not result in any overt phenotype in mice (Esteban et al., Mol. Cell. Biol., 2000, 20(17):6410-3). In contrast, double SOS1 and SOS2 knockout leads to rapid lethality in adult mice (Baltanas et al., Mol. Cell. Biol., 2013, 33(22):4562-78). These published data suggest that selective targeting of individual SOS isoforms (e.g., selective SOS1 targeting) may be adequately tolerated to achieve a therapeutic index between SOS1/RAS-family protein driven cancers (or other SOS1/RAS-family protein pathologies) and normal cells and tissues. [0007] Selective pharmacological inhibition of the binding of the catalytic site of SOS1 to RAS-family proteins is expected to prevent SOS1-mediated activation of RAS- family proteins to the GTP-bound form. Such SOS1 inhibitor compounds are be expected to consequently inhibit signaling in cells downstream of RAS-family proteins (e.g., ERK phosphorylation). In cancer cells associated with dependence on RAS-family proteins (e.g., KRAS mutant cancer cell lines), SOS1 inhibitor compounds are be expected to deliver anti- cancer efficacy (e.g., inhibition of proliferation, survival, metastasis, etc.). High potency towards inhibition of SOS1:RAS-family protein binding (nanomolar level IC50 values) and ERK phosphorylation in cells (nanomolar level IC50 values) are desirable characteristics for a SOS1 inhibitor compound. Furthermore, a desirable characteristic of a SOS1 inhibitor compound would be the selective inhibition of SOS1 over SOS2. This conclusion is based on the viable phenotype of SOS1 knockout mice and lethality of SOS1/SOS2 double knockout mice, as described above. [0008] These characteristics have not been achieved in previously described SOS1 inhibitor compounds. In the last decades, the RAS family proteins-SOS1 protein interaction has gained increasing recognition. Several efforts to identify and optimize binders, which target either the effector binding site of RAS or the catalytic binding site of SOS1 (for a selected review see: Lu et al., ChemMedChem.2016, 11(8):814-21), have been made with limited success. [0009] Recently, small activating molecules have been identified, which bind to a lipophilic pocket of SOS1 in close proximity to the RAS binding site (Burns et al., Proc. Natl. Acad. Sci.2014, 111(9):3401-6). However, binding of these molecules seems to lead to increased nucleotide exchange and thereby activation of RAS instead of deactivation. [0010] In an effort to stabilize the protein-protein-interaction of RAS-family proteins with SOS1 and to prevent reloading of RAS-family proteins with GTP, several different fragments were subsequently identified (Winter et al., J. Med. Chem.2015, 58(5):2265-74). However, reversible binding of fragments to SOS1 did not translate into a measurable effect on the nucleotide exchange and only a weak effect was observed for fragments covalently bound to RAS. [0011] Also recently, studies have been conducted to combine rational design and screening platforms to identify small molecule inhibitors of SOS1 (Evelyn et al., Chem. Biol.2014, 21 (12):1618-28; Evelyn et al., J. Biol. Chem.2015, 290(20):12879-98; Zheng et al., WO 2016/077793), i.e. compounds which bind to SOS1 and inhibit protein-protein interaction with RAS-family proteins. Although compounds with a slight inhibitory effect on SOS1 have been identified, the effects on guanine nucleotide exchange and cellular signal transduction modulation (e.g., ERK phosphorylation) are weak.

In an embodiment, an optionally substituted group has 1 substituent. In another embodiment, an optionally substituted group has 2 substituents. In another embodiment, an optionally substituted group has 3 substituents. In another embodiment, an optionally substituted group has 4 substituents. In another embodiment, an optionally substituted group has 5 substituents. For instance, an alkyl group that is optionally substituted can be a fully saturated alkyl chain (i.e., a pure hydrocarbon). Alternatively, the same optionally substituted alkyl group can have substituents different from hydrogen. For instance, it can, at any point along the chain be bonded to a halogen atom, a hydroxyl group, or any other substituent described herein. Thus the term “optionally substituted” means that a given chemical moiety has the potential to contain other functional groups, but does not necessarily have any further functional groups. [0036] As used herein, “alkyl” may mean a straight chain or branched saturated chain having from 1 to 10 carbon atoms. Representative saturated alkyl groups include, but are not limited to, methyl, ethyl, n-propyl, isopropyl, 2-methyl-1-propyl, 2-methyl-2- propyl, 2-methyl-1-butyl, 3-methyl-1-butyl, 2-methyl-3-butyl, 2,2-dimethyl-1-propyl, 2- methyl-1-pentyl, 3-methyl-1-pentyl, 4-methyl-1-pentyl, 2-methyl-2-pentyl, 3-methyl-2- pentyl, 4-methyl-2-pentyl, 2,2-dimethyl-1-butyl, 3,3-dimethyl-1-butyl, 2-ethyl-1-butyl, butyl, isobutyl, t-butyl, n-pentyl, isopentyl, neopentyl, n-hexyl and the like, and longer alkyl groups, such as heptyl, and octyl and the like. An alkyl group can be unsubstituted or substituted. Alkyl groups containing three or more carbon atoms may be straight or branched. As used herein, “lower alkyl” means an alkyl having from 1 to 6 carbon atoms. [0037] As used herein, the term “heteroalkyl” refers to an “alkyl” group (as defined herein), in which at least one carbon atom has been replaced with a heteroatom (e.g., an O, N, or S atom). The heteroatom may appear in the middle or at the end of the radical. [0038] The term "alkenyl" means an aliphatic hydrocarbon group containing a carbon—carbon double bond and which may be straight or branched having about 2 to about 6 carbon atoms in the chain. Certain alkenyl groups have 2 to about 4 carbon atoms in the chain. Branched means that one or more lower alkyl groups such as methyl, ethyl, or propyl are attached to a linear alkenyl chain. Exemplary alkenyl groups include ethenyl, propenyl, n-butenyl, and i-butenyl. A C2-C6 alkenyl group is an alkenyl group containing between 2 and 6 carbon atoms. [0039] The term "alkynyl" means an aliphatic hydrocarbon group containing a carbon—carbon triple bond and which may be straight or branched having about 2 to about 6 carbon atoms in the chain. Certain alkynyl groups have 2 to about 4 carbon atoms in the chain. Branched means that one or more lower alkyl groups such as methyl, ethyl, or propyl are attached to a linear alkynyl chain. Exemplary alkynyl groups include ethynyl, propynyl, n-butynyl, 2-butynyl, 3-methylbutynyl, and n-pentynyl. A C2-C6 alkynyl group is an alkynyl group containing between 2 and 6 carbon atoms. [0040] As used herein, the term "halo" or "halogen" means a fluoro, chloro, bromo, or iodo group. [0041] The term “oxo” as used herein refers to an “=O” group. When an oxo group is bonded to a carbon atom, it can also be abbreviated herein as C(O) or as C=O. An oxo group can also be bonded to a sulfur atom (e.g., S=O and S(O)2) or at phosphorous atom (e.g., P=O, PO2, PO3, PO4, etc.). [0042] The term “imine” as used herein refers to an “=N” group. When an imine is bonded to a carbon atom, it can also be abbreviated herein as C=N. Nitrogen can also be double bonded to sulfur, e.g., S=N, which is referred to as a thioimine. [0043] The term “annular atoms” used in conjunction with terms relating to ring systems described herein (e.g., cycloalkyl, cycloalkenyl, aryl, heterocyclyl, and heteroaryl) refers to the total number of ring atoms present in the system. “Annular atoms” therefore does not include the atoms present in a substituent attached to the ring. Thus, the number of “annular atoms” includes all atoms present in a fused ring. For example, a 2-indolyl ring, , is considered a 5-membered heteroaryl, but is also a heteroaryl containing 9 annular atoms. In another example, pyridine is considered a 6-membered heteroaryl, and is a heteroaryl containing 6 annular atoms. [0044] "Cycloalkyl" refers to a single saturated all carbon ring having 3 to 20 annular carbon atoms (i.e., C3-C20 cycloalkyl), for example from 3 to 15 annular atoms, for example, from 3 to 12 annular atoms. In certain embodiments, the cycloalkyl group is either monocyclic ("monocyclic cycloalkyl") or contains a fused, bridged or spiro ring system such as a bicyclic system ("bicyclic cycloalkyl") and can be saturated. "Cycloalkyl" includes ring systems where the cycloalkyl ring, as defined above, is fused with one or more cycloalkyl, cycloalkenyl, heterocyclyl, aryl or heteroaryl groups, wherein the point of attachment is on a cycloalkyl ring, and, in such instances, the number of carbon atoms recited continues to designate the number of carbons in the cycloalkyl ring containing the point of attachment. Examples of cycloalkyl groups include cyclohexyl, cycloheptyl, 2-adamantyl ( ), 2-(2,3-dihydro-1H-indene) and 9-fluorenyl ( ). As noted above, cycloalkyl rings can be further characterized by the number of annular atoms. For example, a cyclohexyl ring is a C6 cycloalkyl ring with 6 annular atoms, while 2-(2,3-dihydro-1H-indene) is a C5 cycloalkyl ring with 9 annular atoms. Also, for example, 9-fluorenyl is a C5 cycloalkyl ring with 13 annular atoms and 2- adamantyl is a C6 cycloalkyl with 10 annular atoms. [0045] As used herein, the term “cycloalkenyl” may refer to a partially saturated, monocyclic, fused or spiro polycyclic, all carbon ring having from 3 to 18 carbon atoms per ring and contains at least one double bond. "Cycloalkenyl" includes ring systems where the cycloalkenyl ring, as defined above, is fused with one or more cycloalkyl, cycloalkenyl, heterocyclyl, aryl or heteroaryl groups, wherein the point of attachment is on a cycloalkenyl ring, and, in such instances, the number of carbon atoms recited continues to designate the number of carbons in the cycloalkenyl ring containing the point of attachment. Cycloalkenyl rings can be further characterized by the number of annular atoms. Examples of cycloalkenyl include 1-cyclohex-1-enyl and cyclopent-1-enyl. [0046] The term "aryl" as used herein refers to a single all carbon aromatic ring or a multiple condensed all carbon ring system wherein at least one of the rings is aromatic. For example, in certain embodiments, an aryl group has 5 to 20 annular carbon atoms, 5 to 14 annular carbon atoms, or 5 to 12 annular carbon atoms. Aryl also includes multiple condensed ring systems (e.g., ring systems comprising 2, 3 or 4 rings) having about 9 to 20 carbon atoms in which at least one ring is aromatic and wherein the other rings may be aromatic or not aromatic (i.e., cycloalkyl). "Aryl" includes ring systems where the aryl ring, as defined above, is fused with one or more cycloalkyl, cycloalkenyl, heterocyclyl, aryl or heteroaryl groups, and wherein the point of attachment is on an aryl ring, and, in such instances, the number of carbon atoms recited continues to designate the number of carbon atoms in the aryl ring containing the point of attachment. Examples of aryl groups include phenyl and 5-(2,3-dihydro-1H-indene): . As noted above, aryl rings can be further characterized by the number of annular atoms. For example, phenyl is a C6 aryl with 6 annular atoms, while 5-(2,3-dihydro-1H-indene) is a C6 aryl with 9 annular atoms. [0047] "Heterocyclyl" as used herein refers to a single saturated or partially unsaturated non-aromatic ring or a non-aromatic multiple ring system (including fused and spiro polycyclic) that has at least one heteroatom in the ring (at least one annular heteroatom selected from oxygen, nitrogen, phosphorus, and sulfur). Unless otherwise specified, a heterocyclyl group has from 5 to about 20 annular atoms, for example from 5 to 15 annular atoms, for example from 5 to 10 annular atoms. Thus, the term includes single saturated or partially unsaturated rings (e.g., 3, 4, 5, 6 or 7-membered rings) having from about 1 to 6 annular carbon atoms and from about 1 to 3 annular heteroatoms selected from the group consisting of oxygen, nitrogen, phosphorus, and sulfur in the ring. The term also includes single saturated or partially unsaturated rings (e.g., 5, 6, 7, 8, 9, or 10- membered rings) having from about 4 to 9 annular carbon atoms and from about 1 to 3 annular heteroatoms selected from the group consisting of oxygen, nitrogen, phosphorus, and sulfur in the ring. “Heterocyclyl" includes ring systems where the heterocyclyl ring, as defined above, is fused with one or more cycloalkyl, cycloalkenyl, heterocyclyl, aryl or heteroaryl groups, wherein the point of attachment is on a heterocyclic ring, and, in such instances, the number of ring members recited continues to designate the number of annular atoms in the heterocyclic ring containing the point of attachment. Heterocyclic rings can be further characterized by the number of annular atoms. Examples of heterocyclic groups include piperidinyl (6-membered heterocycle with 6 annular atoms), azepanyl (7-membered heterocycle with 7 annular atoms), and 3-chromanyl (6-membered heterocycle with 10 annular atoms) . [0048] The term "heteroaryl" as used herein refers to a single aromatic ring that has at least one atom other than carbon in the ring, wherein the atom is selected from the group consisting of oxygen, nitrogen and sulfur; the term also includes multiple condensed ring systems that have at least one such aromatic ring. Thus, the term includes single heteroaryl rings of from about 1 to 10 annular carbon atoms and about 1-5 annular heteroatoms selected from the group consisting of oxygen, nitrogen and sulfur in the rings. The sulfur and nitrogen atoms may also be present in an oxidized form provided the ring is aromatic. "Heteroaryl" includes ring systems where the heteroaryl ring, as defined above, is fused with one or more cycloalkyl, cycloalkenyl, heterocyclyl, aryl or heteroaryl groups, wherein the point of attachment is on a heteroaryl ring, and, in such instances, the number of ring members continues to designate the number of ring members in the heteroaryl ring containing the point of attachment. Heteroaryl rings can be further characterized by the number of annular atoms. For example, pyridine is a 6-membered heteroaryl having 6 annular atoms. [0049] The disclosure also includes pharmaceutical compositions comprising an effective amount of a disclosed compound, or a pharmaceutically acceptable salt, solvate, stereoisomer, prodrug, or tautomer thereof, and a pharmaceutically acceptable carrier.

[0050] The term “tautomers” refers to a set of compounds that have the same number and type of atoms, but differ in bond connectivity and are in equilibrium with one another. A “tautomer” is a single member of this set of compounds. Typically, a single tautomer is drawn but it is understood that this single structure is meant to represent all possible tautomers that might exist. Examples include enol-ketone tautomerism. When a ketone is drawn it is understood that both the enol and ketone forms are part of the present disclosure. [0051] Unless otherwise stated, structures depicted herein are also meant to include compounds that differ only in the presence of one or more isotopically enriched atoms. Exemplary isotopes that can be incorporated into compounds of the present invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine, chlorine, and iodine, such as 2H, 3H, 11C, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 32P, 33P, 35S, 18F, 36Cl, 123I and 125I. Isotopically-labeled compounds (e.g., those labeled with 3H and 14C) can be useful in compound or substrate tissue distribution assays. Tritiated (i.e., 3H) and carbon-14 (i.e., 14C) isotopes can be useful for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium (i.e., 2H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements). In some embodiments, one or more hydrogen atoms are replaced by 2H or 3H, or one or more carbon atoms are replaced by 13C- or 14C-enriched carbon. Positron emitting isotopes such as 15O, 13N, 11C, and 18F are useful for positron emission tomography (PET) studies to examine substrate receptor occupancy. Preparations of isotopically labelled compounds are known to those of skill in the art. For example, isotopically labeled compounds can generally be prepared by following procedures analogous to those disclosed for compounds of the present invention described herein, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent. [0052] The term “prodrug,” as used in this disclosure, means a compound which is convertible in vivo by metabolic means (e.g., by hydrolysis) to a disclosed compound. Furthermore, as used herein a prodrug is a drug which is inactive in the body, but is transformed in the body typically either during absorption or after absorption from the gastrointestinal tract into the active compound. The conversion of the prodrug into the active compound in the body may be done chemically or biologically (i.e., using an enzyme). [0053] The term "solvate" refers to a complex of variable stoichiometry formed by a solute and solvent. Such solvents for the purpose of the present disclosure may not interfere with the biological activity of the solute. Examples of suitable solvents include, but are not limited to, water, MeOH, EtOH, and AcOH. Solvates wherein water is the solvent molecule are typically referred to as hydrates. Hydrates include compositions containing stoichiometric amounts of water, as well as compositions containing variable amounts of water. [0054] The term "isomer" refers to compounds that have the same composition and molecular weight but differ in physical and/or chemical properties. The structural difference may be in constitution (geometric isomers) or in the ability to rotate the plane of polarized light (stereoisomers). With regard to stereoisomers, the compounds herein may have one or more asymmetric carbon atom and may occur as racemates, racemic mixtures and as individual enantiomers or diastereomers. [0055] The term "stereoisomers" refers to the set of compounds which have the same number and type of atoms and share the same bond connectivity between those atoms, but differ in three dimensional structure. The term "stereoisomer" refers to any member of this set of compounds. For instance, a stereoisomer may be an enantiomer or a diastereomer. [0056] The term "enantiomers" refers to a pair of stereoisomers which are non- superimposable mirror images of one another. The term "enantiomer” refers to a single member of this pair of stereoisomers. The term "racemic" refers to a 1:1 mixture of a pair of enantiomers. [0057] The term "diastereomers" refers to the set of stereoisomers which cannot be made superimposable by rotation around single bonds. For example, cis- and trans- double bonds, endo- and exo-substitution on bicyclic ring systems, and compounds containing multiple stereogenic centers with different relative configurations are considered to be diastereomers. The term "diastereomer" refers to any member of this set of compounds. In some examples presented, the synthetic route may produce a single diastereomer or a mixture of diastereomers. [0058] An “effective amount” when used in connection with a compound is an amount effective for treating or preventing a disease in a subject as described herein. [0059] The term “carrier”, as used in this disclosure, encompasses excipients and diluents and means a material, composition or vehicle, such as a liquid or solid filler, diluent, excipient, solvent or encapsulating material, involved in carrying or transporting a pharmaceutical agent from one organ, or portion of the body, to another organ, or portion of the body of a subject. [0060] The term “treating” with regard to a subject, refers to improving at least one symptom of the subject’s disorder. Treating includes curing, improving, or at least partially ameliorating the disorder.

For instance, preventing can include administering to the subject a compound disclosed herein before a subject is afflicted with a disease and the administration will keep the subject from being afflicted with the disease. [0062] The terms “inhibiting” and “reducing,” or any variation of these terms, includes any measurable or complete inhibition to achieve a desired result. For example, there may be a decrease of about, at most about, or at least about 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 99%, or more, or any range derivable therein, reduction of activity (e.g., SOS1:Ras-family protein binding activity) compared to normal. [0063] The term “disorder” is used in this disclosure to mean, and is used interchangeably with, the terms disease, condition, or illness, unless otherwise indicated. [0064] The term “administer”, “administering”, or “administration” as used in this disclosure refers to either directly administering a disclosed compound or a pharmaceutically acceptable salt, solvate, stereoisomer, prodrug, or tautomer of the disclosed compound or a composition to a subject, or administering a prodrug derivative or analog of the compound or pharmaceutically acceptable salt of the compound or composition to the subject, which can form an equivalent amount of active compound within the subject’s body. [0065] A "patient" or “subject” is a mammal, e.g., a human, mouse, rat, guinea pig, dog, cat, horse, cow, pig, or non-human primate, such as a monkey, chimpanzee, baboon or rhesus.

Methods of Synthesizing the Disclosed Compounds [0143] The compounds of the present disclosure may be made by a variety of methods, including standard chemistry. Suitable synthetic routes are depicted in the schemes given below. [0144] The compounds of any of the formulae described herein may be prepared by methods known in the art of organic synthesis as set forth in part by the following synthetic schemes and examples. In the schemes described below, it is well understood that protecting groups for sensitive or reactive groups are employed where necessary in accordance with general principles or chemistry. Protecting groups are manipulated according to standard methods of organic synthesis (T. W. Greene and P. G. M. Wuts, "Protective Groups in Organic Synthesis", Third edition, Wiley, New York 1999). These groups are removed at a convenient stage of the compound synthesis using methods that are readily apparent to those skilled in the art. The selection processes, as well as the reaction conditions and order of their execution, shall be consistent with the preparation of compounds of any formula disclosed herein. [0145] Those skilled in the art will recognize if a stereocenter exists in any of the compounds of the present disclosure. Accordingly, the present invention includes both possible stereoisomers (unless specified in the synthesis) and includes not only racemic compounds but the individual enantiomers and/or diastereomers as well. When a compound is desired as a single enantiomer or diastereomer, it may be obtained by stereospecific synthesis or by resolution of the final product or any convenient intermediate. Resolution of the final product, an intermediate, or a starting material may be affected by any suitable method known in the art. See, for example, "Stereochemistry of Organic Compounds" by E. L. Eliel, S. H. Wilen, and L. N. Mander (Wiley-lnterscience, 1994). Preparation of Compounds [0146] The compounds described in this disclosure may be synthesized from commercially available starting materials using known organic, inorganic, and/or enzymatic processes. [0147] The compounds of the present disclosure can be prepared in a number of ways well known to those skilled in the art of organic synthesis. By way of example, compounds of the disclosure can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art. These methods include but are not limited to those methods described below. [0148] A general synthesis of substituted 1H-indazole-7-carboxamides or analogous heterocycles is outlined in Scheme 1. Scheme 1: [0149] 5-bromo-1H-indazole-7-carboxylic acid or an analogous appropriately substituted halogenated heterocyclic ring can undergo an amide coupling with an appropriately substituted benzyl amine. The resulting phenylethyl 1H-indazole-7- carboxamide or analogous halogenated heterocyclic ring can then be used for cross coupling reactions with appropriately substituted, amines, amides, alkyls, olefins, aromatics, or heteroaromatics. Additional deprotection and/or functionalization steps can be required to produce the final compound. [0150] Alternatively, final compounds with an oxygen substituent in position 5 can be prepared through an SNAr reaction between an alcohol and methyl 5-fluoro-1H- indole-7-carboxylate or an analogous appropriately substituted halogenated heterocycle, as outlined in Scheme 2. The resulting aryl ether can then undergo an amide coupling with an appropriately substituted benzyl amine. Additional deprotection and/or functionalization steps can be required to produce the final compound. Scheme 2: [0151] A general synthesis of substituted 1H-pyrrolo[3,2-b]pyridine-7- carboxamides or analogous heterocycles is outlined in Scheme 3. Scheme 3: [0152] 3-amino-6-bromopyridine or an analogous appropriately substituted halogenated heterocyclic ring can undergo cross coupling reactions with appropriately substituted, amines, amides, alkyls, olefins, aromatics, or heteroaromatics. The resulting intermediate can then be used in a cross-coupling reaction with an appropriate terminal alkyne. The resulting 2-alkynylpyridin-3-amine can then undergo an intramolecular hydroamination in the presence of a Cu catalyst. The resulting 7-chloro-1H-pyrrolo[3,2- b]pyridine or analogous appropriately halogenated heterocycle can then be coupled to appropriately substituted benzyl amine in the presence of carbon monoxide a palladium catalyst. Additional deprotection and/or functionalization steps can be required to produce the final compound. [0153] The appropriately substituted benzyl amine building block can be prepared as outlined in Scheme 4. Appropriately substituted aryl or heteroaryl bromides can be transformed into the corresponding acetyl arene or heteroarene by metal halogen exchange followed by the addition of an acetylating reagent. The ketone functionality can then be stereoselectively transformed into the desired chiral benzylamine using Ellman’s reagent.

When combined, dosages of a compound of the invention and dosages of the one or more additional therapies (e.g., non- drug treatment or therapeutic agent) provide a therapeutic effect (e.g., synergistic or additive therapeutic effect). A compound of the present invention and an additional therapy, such as an anti-cancer agent, may be administered together, such as in a unitary pharmaceutical composition, or separately and, when administered separately, this may occur simultaneously or sequentially. Such sequential administration may be close or remote in time. [0190] In some embodiments, the additional therapy is the administration of side- effect limiting agents (e.g., agents intended to lessen the occurrence or severity of side effects of treatment. For example, in some embodiments, the compounds of the present disclosure can also be used in combination with a therapeutic agent that treats nausea. Examples of agents that can be used to treat nausea include: dronabinol, granisetron, metoclopramide, ondansetron, and prochlorperazine, or pharmaceutically acceptable salts thereof. [0191] In some embodiments, the one or more additional therapies includes a non-drug treatment (e.g., surgery or radiation therapy).

In some embodiments, the one or more additional therapies includes a non-drug treatment (e.g., surgery or radiation therapy) and a therapeutic agent (e.g., a compound or biologic that is an anti-angiogenic agent, signal transduction inhibitor, antiproliferative agent, glycolysis inhibitor, or autophagy inhibitor). In other embodiments, the one or more additional therapies includes two therapeutic agents. In still other embodiments, the one or more additional therapies includes three therapeutic agents. In some embodiments, the one or more additional therapies includes four or more therapeutic agents. Non-drug therapies [0192] Examples of non-drug treatments include, but are not limited to, radiation therapy, cryotherapy, hyperthermia, surgery (e.g., surgical excision of tumor tissue), and T cell adoptive transfer (ACT) therapy. [0193] In some embodiments, the compounds of the disclosure may be used as an adjuvant therapy after surgery. In some embodiments, the compounds of the invention may be used as a neo-adjuvant therapy prior to surgery. [0194] Radiation therapy may be used for inhibiting abnormal cell growth or treating a hyperproliferative disorder, such as cancer, in a subject (e.g., mammal (e.g., human)).

Radiation therapy can be administered through one of several methods, or a combination of methods, including, without limitation, external-beam therapy, internal radiation therapy, implant radiation, stereotactic radiosurgery, systemic radiation therapy, radiotherapy and permanent or temporary interstitial brachy therapy. The term "brachy therapy," as used herein, refers to radiation therapy delivered by a spatially confined radioactive material inserted into the body at or near a tumor or other proliferative tissue disease site. The term is intended, without limitation, to include exposure to radioactive isotopes (e.g., At-211, I-131, I-125, Y-90, Re-186, Re-188, Sm-153, Bi-212, P-32, and radioactive isotopes of Lu). Suitable radiation sources for use as a cell conditioner of the present invention include both solids and liquids. By way of non-limiting example, the radiation source can be a radionuclide, such as I-125, I-131, Yb-169, Ir-192 as a solid source, I-125 as a solid source, or other radionuclides that emit photons, beta particles, gamma radiation, or other therapeutic rays. The radioactive material can also be a fluid made from any solution of radionuclide(s), e.g., a solution of I-125 or I-131, or a radioactive fluid can be produced using a slurry of a suitable fluid containing small particles of solid radionuclides, such as Au-198, or Y-90. Moreover, the radionuclide(s) can be embodied in a gel or radioactive micro spheres. [0195] In some embodiments, the compounds of the present disclosure can render abnormal cells more sensitive to treatment with radiation for purposes of killing or inhibiting the growth of such cells. Accordingly, this invention further relates to a method for sensitizing abnormal cells in a mammal to treatment with radiation which comprises administering to the mammal an amount of a compound of the present invention, which amount is effective to sensitize abnormal cells to treatment with radiation. The amount of the compound in this method can be determined according to the means for ascertaining effective amounts of such compounds described herein. In some embodiments, the compounds of the present invention may be used as an adjuvant therapy after radiation therapy or as a neo-adjuvant therapy prior to radiation therapy. [0196] In some embodiments, the non-drug treatment is a T cell adoptive transfer (ACT) therapy. In some embodiments, the T cell is an activated T cell. The T cell may be modified to express a chimeric antigen receptor (CAR). CAR modified T (CAR-T) cells can be generated by any method known in the art. For example, the CAR-T cells can be generated by introducing a suitable expression vector encoding the CAR to a T cell. Prior to expansion and genetic modification of the T cells, a source of T cells is obtained from a subject. T cells can be obtained from a number of sources, including peripheral blood mononuclear cells, bone marrow, lymph node tissue, cord blood, thymus tissue, tissue from a site of infection, ascites, pleural effusion, spleen tissue, and tumors. In certain embodiments of the present invention, any number of T cell lines available in the art may be used. In some embodiments, the T cell is an autologous T cell. Whether prior to or after genetic modification of the T cells to express a desirable protein (e.g., a CAR), the T cells can be activated and expanded generally using methods as described, for example, in U.S. Patents 6,352,694; 6,534,055; 6,905,680; 6,692,964; 5,858,358; 6,887,466; 6,905,681; 7,144,575; 7,067,318; 7,172,869; 7,232,566; 7,175,843; 7,572,631; 5,883,223; 6,905,874; 6,797,514; and 6,867,041.

In some embodiments, the mTOR inhibitor is a bisteric inhibitor (see, e.g., WO2018204416, WO2019212990 and WO2019212991), such as RMC-5552. [0223] BRAF inhibitors that may be used in combination with compounds of the invention include, for example, vemurafenib, dabrafenib, and encorafenib. A BRAF may comprise a Class 3 BRAF mutation. In some embodiments, the Class 3 BRAF mutation is selected from one or more of the following amino acid substitutions in human BRAF: D287H; P367R; V459L; G466V; G466E; G466A; S467L; G469E; N581S; N581I; D594N; D594G; D594A; D594H; F595L; G596D; G596R and A762E. [0224] MCL-1 inhibitors include, but are not limited to, AMG-176, MIK665, and S63845. The myeloid cell leukemia-1 (MCL-1) protein is one of the key anti-apoptotic members of the B-cell lymphoma-2 (BCL-2) protein family. Over-expression of MCL-1 has been closely related to tumor progression as well as to resistance, not only to traditional chemotherapies but also to targeted therapeutics including BCL-2 inhibitors such as ABT- 263. [0225] In some embodiments, the additional therapeutic agent is a SHP2 inhibitor. SHP2 is a non-receptor protein tyrosine phosphatase encoded by the PTPN11 gene that contributes to multiple cellular functions including proliferation, differentiation, cell cycle maintenance and migration. SHP2 has two N-terminal Src homology 2 domains (N-SH2 and C-SH2), a catalytic domain (PTP), and a C-terminal tail. The two SH2 domains control the subcellular localization and functional regulation of SHP2. The molecule exists in an inactive, self-inhibited conformation stabilized by a binding network involving residues from both the N-SH2 and PTP domains. Stimulation by, for example, cytokines or growth factors acting through receptor tyrosine kinases (RTKs) leads to exposure of the catalytic site resulting in enzymatic activation of SHP2. [0226] SHP2 is involved in signaling through the RAS-mitogen-activated protein kinase (MAPK), the JAK-STAT or the phosphoinositol 3-kinase-AKT pathways. Mutations in the PTPN11 gene and subsequently in SHP2 have been identified in several human developmental diseases, such as Noonan Syndrome and Leopard Syndrome, as well as human cancers, such as juvenile myelomonocytic leukemia, neuroblastoma, melanoma, acute myeloid leukemia and cancers of the breast, lung and colon. Some of these mutations destabilize the auto-inhibited conformation of SHP2 and promote autoactivation or enhanced growth factor driven activation of SHP2. SHP2, therefore, represents a highly attractive target for the development of novel therapies for the treatment of various diseases including cancer. A SHP2 inhibitor (e.g., RMC-4550 or SHP099) in combination with a RAS pathway inhibitor (e.g., a MEK inhibitor) have been shown to inhibit the proliferation of multiple cancer cell lines in vitro (e.g., pancreas, lung, ovarian and breast cancer). Thus, combination therapy involving a SHP2 inhibitor with a RAS pathway inhibitor could be a general strategy for preventing tumor resistance in a wide range of malignancies, and may form the basis of a triple combination inhibitor with a SOS1 inhibitor. [0227] Non-limiting examples of such SHP2 inhibitors that are known in the art, include: Chen et al. Mol Pharmacol.2006, 70, 562; Sarver et al., J. Med. Chem.2017, 62, 1793; Xie et al., J. Med.

The IMiD class includes thalidomide and its analogues (lenalidomide, pomalidomide, and apremilast). [0232] Exemplary anti-PD-1 antibodies and methods for their use are described by Goldberg et al., Blood 2007, 110(1):186-192; Thompson et al., Clin. Cancer Res.2007, 13(6):1757-1761; and WO06/121168 A1), as well as described elsewhere herein. [0233] GITR agonists include, but are not limited to, GITR fusion proteins and anti-GITR antibodies (e.g., bivalent anti-GITR antibodies), such as, a GITR fusion protein described in U.S. Pat. No.6,111,090, U.S. Pat. No.8,586,023, WO2010/003118 and WO2011/090754; or an anti-GITR antibody described, e.g., in U.S. Pat. No.7,025,962, EP 1947183, U.S. Pat. No.7,812,135, U.S. Pat.

Additional Compounds [0379] The compounds listed in Table B were prepared using methods similar to those described above for Examples 1-20. Table B
Biological Examples Potency assay: Measurement of the binding affinity of Compounds of the Disclosure to SOS1 using Surface Plasmon Resonance (SPR) [0380] The purpose of the SPR assay was to measure the direct binding of compounds to SOS1 catalytic domain (residues 564 – 1049) immobilized on a sensor chip. Data was reported as equilibrium dissociation constant (Kd) values. [0381] Using a GE Biacore 8K SPR instrument, avi-tagged SOS1 catalytic domain protein was immobilized to a level of approximately 6000 response units (RU) on a streptavidin-coated SPR sensor chip in assay buffer containing 0.01 M HEPES, 0.15 M NaCl and 0.05% v/v Surfactant P20. In assay buffer containing 2% DMSO, concentration series of test compounds were generated spanning 5 µM to 4.9 nM over ten 2-fold dilutions. For each test compound, a separate 0 µM sample was generated for use during subsequent double reference subtraction. Serially for each test compound, individual dilution samples were flowed over the immobilized SOS1 protein at a flow rate of 50 µL/minute to monitor the association with SOS1. Dissociation of bound test compound from the SOS1 protein was immediately monitored by flowing assay buffer over the sensor surface and monitoring the decrease in binding signal back to the baseline level seen in the absence of compound. This was repeated for all compound dilutions in each series. The binding level response for each test compound concentration was noted immediately prior to the end of the association phase, and a secondary plot generated showing binding response level versus test compound concentration generated for each compound dilution series. This data was fitted to a model describing reversible equilibrium 1:1 binding between test compound and SOS1, yielding an estimate of the Kd value for the interaction. [0382] SOS1 using Surface Plasmon Resonance (SPR) results are shown in Table C below. Table C Potency assay: pERK [0383] The purpose of this assay is to measure the ability of test compounds to inhibit SOS1 function in cells. SOS1 activates RAS proteins by catalyzing the conversion of RAS·GDP to RAS·GTP in response to receptor tyrosine kinase activation. Activation of RAS induces a sequence of cellular signaling events that results in increased phosphorylation of ERK at Threonine 202 and Tyrosine 204 (pERK). The procedure described below measures the level of cellular pERK in response to test compounds in PC- 9 cells (EGFR Ex19Del). [0384] PC-9 cells were grown and maintained using media and procedures recommended by the ATCC. On the day prior to compound addition, cells were plated in 384-well cell culture plates (40 µL/well) and grown overnight in a 37°C, 5% CO2 incubator. Test compounds were prepared in 10, 3-fold dilutions in DMSO, with a top concentration of 10 mM. On the day of the assay, 40 nL of test compound was added to each well of cell culture plate using an Echo550 liquid handler (LabCyte). Concentrations of test compound were tested in duplicate with highest test concentration being 10 µM. After compound addition, cells were incubated for 1 hour at 37°C, 5% CO2. Following incubation, culture medium was removed and cells were washed once with phosphate buffered saline. [0385] Cellular pERK level was determined using the AlphaLISA SureFire Ultra p-ERK1/2 Assay Kit (PerkinElmer). Cells were lysed in 25 µL lysis buffer, with shaking at 600 RPM at room temperature for 15 minutes. Lysate (10 µL) was transferred to a 384- well Opti-plate (PerkinElmer) and 5 µL acceptor mix was added. The plate was centrifuged at 1000 RPM for 1 minute, and incubated in the dark for 2 hours. Following this incubation, 5 µL of donor mix was added, the plate was sealed and centrifuged at 1000 RPM for 1 minute, and the mixture was incubated for 2 hours at room temperature. Signal was read on an Envision plate reader (PerkinElmer) using standard AlphaLISA settings. Analysis of raw data was carried out in Excel (Microsoft) and Prism (GraphPad). Signal was plotted vs. the decadal logarithm of compound concentration, and IC50 was determined by fitting a 4-parameter sigmoidal concentration response model. [0386] SOS1 pERK IC50 Assay results are shown in Table D below. Table D Mode of Action Assay: Inhibition of SOS1 Nucleotide Exchange Activity [0387] The purpose of this assay was to characterize the inhibitory activity of compounds on SOS1 nucleotide exchange of KRAS. Data was reported as IC50 values based on the TR-FRET signal. [0388] Note – the following protocol describes a procedure for monitoring the inhibition of SOS1 nucleotide exchange activity of wild-type KRAS in response to a compound of the invention. Other KRAS mutants and RAS isoforms maybe employed. [0389] In assay buffer containing 20 mM HEPES, pH 7.5, 150 mM NaCl, 5 mM MgCl2, 0.05% Tween-20, 0.1% BSA, 1 mM DTT, concentration series of test compounds were generated spanning 100 µM to 1.7 nM over eleven 3-fold serial dilutions in a 384- well assay plate at a volume of 20 µL. The purified tagless catalytic domain of SOS1 (residues 564 - 1049) was first diluted in assay buffer at a concentration of 100 nM, and then 20 µL of the SOS1 containing solution was directly dispensed into compound plates. The SOS1/compound mixture was incubated at room temperature with constant mixing on an orbital shaker for 20 minutes to allow the reaction to reach equilibrium. A KRAS mixture was prepared by diluting 66.7 nM avi-tagged KRAS (residue 1 – 169), 3.33 nM Streptavidin-Tb and 333 nM EDA–GTP–DY-647P1 in assay buffer. This mixture was prepared immediately before addition to the SOS1/compound mixture to prevent intrinsic nucleotide exchange. Then 5 µL of the pre-incubated SOS1/compound mixture and 7.5 µL of the KRAS mixture were added sequentially in a 384-well low volume black round bottom plate and incubated at room temperature with constant shaking for 30 minutes. Time-resolved fluorescence was measured on a PerkinElmer Envision plate reader. DMSO and 10 µM of compound (i) were used as negative and positive controls, respectively. compound (i) [0390] Three replicates were performed for each compound. Data were normalized by the following: (Positive control - Sample signal)/(Positive control – negative control)*100. The data were fit using a four-parameter logistic fit.
