FUSED RING COMPOUNDS AS INHIBITORS OF FGFR4 TYROSINE KINASES
TECHNICAL FIELD
The present disclosure relates to fused ring compounds, and pharmaceutical compositions including the same, that are inhibitors of one or more FGFR enzymes and are useful in the treatment of FGFR-associated diseases, especially FGFR4-associated diseases, such as cancer.
BACKGROUND
The Fibroblast Growth Factor Receptor (FGFR) tyrosine kinase (TK) family consists of four members (FGFR1-4) , activated through 22 different fibroblast growth factor (FGF) ligands, which regulate multiple biological processes, including cell proliferation, migration, differentiation, apoptosis, metabolism, and angiogenesis (Wilkie et al., Curr. Biol. 1995, 5, 500–507) . When FGF ligands bind to their specific FGFRs, the receptors undergo dimerization and phosphorylation of the intracellular tyrosine kinase domains which results in the activation of a cascade of downstream events including the mitogen-activated protein kinase (MAPK) , the signal transducer and activator of transcription (STAT) , the phosphoinositide-3-kinase (PI3K) /Akt, the nuclear factor-kappa B, and the PLC-gamma DAG/PKC/IP3-Ca2+ pathways resulting in DNA transcription. These pathways have critical roles in cell proliferation, metabolism and survival (Eswarakumar et al. Cytokine &Growth Factor Reviews, 2005, 16, 139-149) .
Genetic aberrations such as gene amplifications and activating mutations are common in the FGFR family members. FGFR signaling has been demonstrated to mediate crucial physiological processes such as embryogenesis, tissue repair, wound healing, and angiogenesis (Dieci et al., Cancer Discovery, 2013, 3, 264-279) . Additionally, the dysregulation of FGFR has also been implicated in the poor prognosis, metastatic progression, and resistance to both cytotoxic and targeted agents during clinical treatment (Turner et al., Cancer Res. 2010, 70, 2085-2094; Greulich et al., Trends Mol. Med. 2011, 17, 283-292; Ho et al., Drug Discovery Today 2014, 19, 51-62; Kim et al., Oncogene 2015, 34, 1083-1093; Saito et al., BMC Cancer 2015, 15, 82) . Aberrant signaling of the FGF/FGFR pathway has the potential to drive the pathogenesis of a broad range of human malignancies, including urothelial cancers, breast cancers, endometrial cancers, squamous lung cancers, ovarian cancers, and cholangiocarcinomas (Helsten et al., Clin. Cancer Res. 2016, 22, 259-267; Turner et al., Nat. Rev. Cancer 2010, 10, 116–129) . Therefore, development of inhibitors targeting FGFR may be useful in the clinical treatment of cancer and other diseases that have elevated FGF or FGFR activity.
Fibroblast growth factor receptor 4 (FGFR4) is a tyrosine kinase receptor that selectively binds broblast growth factor 19 (FGF19) to stimulate autophosphorylation in trans and mediates cellular effects via downstream MAP kinase and AKT signaling pathways. Treatment of transgenic mice harboring liver tumors (caused by overexpression of FGF19) with neutralizing antibodies against FGFR4 or FGF19 has been shown to be effective in reducing tumorigenesis (Desnoyers, L. R. et al., Oncogene 2008, 27, 85-97. ) . Additionally, FGF19 transgenic mice failed to develop liver tumors when FGFR4 was knocked out (French, D. M. et al., PLoS One 2012, 7, No. e36713. ) . Together, these studies indicate that targeting FGFR4 for the treatment of FGF19/FGFR4-driven cancers is a promising therapeutic strategy.

Tautomeric forms include prototropic tautomers which are isomeric protonation states having the same empirical formula and total charge. Example prototropic tautomers include ketone -enol pairs, amide -imidic acid pairs, lactam -lactim pairs, amide -imidic acid pairs, enamine imine pairs, and annular forms where a proton can occupy two or more positions of a heterocyclic system, for example, 1H-and 3H-imidazole, 1H-, 2H-and 4H-1, 2, 4-triazole, 1H-and 2H-isoindole, and 1H-and 2H-pyrazole. Tautomeric forms can be in equilibrium or sterically locked into one form by appropriate substitution.
In some embodiments, the compounds of the present disclosure may exist as rotational isomers. In some embodiments, the compounds of the present disclosure exist as mixtures of rotational isomers in any proportion. In other embodiments, the compounds of the present disclosure exist as particular rotational isomers, substantially free of other rotational isomers.
Compounds of the disclosure can also include all isotopes of atoms occurring in the intermediates or final compounds. Isotopes include those atoms having the same atomic number but different mass numbers. For example, isotopes of hydrogen include tritium and deuterium.
In some embodiments, the compounds of the disclosure, and salts thereof, are substantially isolated. By “substantially isolated” is meant that the compound is at least partially or substantially separated from the environment in which is formed or detected.

Salts further include, by way of example only, sodium, potassium, calcium, magnesium, ammonium, tetraalkylammonium, and the like; and when the compound contains a basic functionality, salts of non-toxic organic or inorganic acids, such as hydrochloride, hydrobromide, tartrate, mesylate, acetate, maleate, oxalate and the like.
A “pharmaceutically acceptable excipient” refers to a substance that is non-toxic, biologically tolerable, and otherwise biologically suitable for administration to a subject, such as an inert substance, added to a pharmacological composition or otherwise used as a vehicle, carrier, or diluent to facilitate administration of an agent and that is compatible therewith. Examples of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils, and polyethylene glycols.
The term “therapeutically effective amount” as used herein refers to the amount of active compound or pharmaceutical agent that elicits the biological or medicinal response in a tissue, system, animal, individual or human that is being sought by a researcher, veterinarian, medical doctor or other clinician, which includes one or more of the following: (1) Preventing the disease; for example, preventing a disease, condition or disorder in an individual that may be predisposed to the disease, condition or disorder but does not yet experience or display the pathology or symptomatology of the disease, (2) Inhibiting the disease; for example, inhibiting a disease, condition or disorder in an individual that is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder (i.e., arresting further development of the pathology and/or symptomatology) , and (3) Ameliorating the disease; for example, ameliorating a disease, condition or disorder in an individual that is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder (i.e., reversing the pathology and/or symptomatology) .
A “solvate” refers to a physical association of a compound of Formula I with one or more solvent molecules.
A “subject” refers to a mammal, particularly a human. The terms “human, ” “patient, ” and “subject” are used interchangeably herein.
“Treating” or “treatment” of any disease or disorder refers, in one embodiment, to ameliorating the disease or disorder (i.e., arresting or reducing the development of the disease or at least one of the clinical symptoms thereof) . In another embodiment “treating” or “treatment” refers to ameliorating at least one physical parameter, which may not be discernible by the subject. In yet another embodiment, “treating” or “treatment” refers to modulating the disease or disorder, either physically, (e.g., stabilization of a discernible symptom) , physiologically, (e.g., stabilization of a physical parameter) , or both. In yet another embodiment, “treating” or “treatment” refers to delaying the onset of the disease or disorder.
“Compounds of the present disclosure, ” and equivalent expressions, are meant to embrace compounds of Formula I as described herein, as well as its subgenera for example, Formulae I-1 to I-5, which expression includes the stereoisomers (e.g., entaniomers, diastereomers) and constitutional isomers (e.g., tautomers) of compounds of Formula I as well as the pharmaceutically acceptable salts, where the context so permits.
As used herein, the term “isotopic variant” refers to a compound that contains proportions of isotopes at one or more of the atoms that constitute such compound that is greater than natural abundance. For example, an “isotopic variant” of a compound can be radiolabeled, that is, contain one or more radioactive isotopes, or can be labeled with non-radioactive isotopes such as for example, deuterium (
2H or D) , carbon-13 (
13C) , nitrogen-15 (
15N) , or the like. It will be understood that, in a compound where such isotopic substitution is made, the following atoms, where present, may vary, so that for example, any hydrogen may be
2H/D, any carbon may be
13C, or any nitrogen may be
15N, and that the presence and placement of such atoms may be determined within the skill of the art.
The term “proliferative disorder” refers to a disorder or condition characterized by abnormal and uncontrolled cell proliferation. It may start at one site (primary site) with the potential to invade and to spread to other sites (secondary sites, metastases) which differentiate cancer (malignant tumor) from benign tumor. Virtually all the organs can be affected, leading to more than 100 types of cancer that can affect humans. Cancer is a typical proliferative disorder and can result from many causes including genetic predisposition, viral infection, exposure to ionizing radiation, exposure environmental pollutant, tobacco and or alcohol use, obesity, poor diet, lack of physical activity or any combination thereof.
It is also to be understood that compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers. ” Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers, ” for example, diastereomers, enantiomers, and atrop-isomers. The compounds of this disclosure may possess one or more asymmetric centers; such compounds can therefore be produced as individual (R) -or (S) -stereoisomers at each asymmetric center, or as mixtures thereof. Unless indicated otherwise, the description or naming of a particular compound in the specification and claims is intended to include all stereoisomers and mixtures, racemic or otherwise, thereof. Where one chiral center exists in a structure, but no specific stereochemistry is shown for that center, both enantiomers, individually or as a mixture of enantiomers, are encompassed by that structure. Where more than one chiral center exists in a structure, but no specific stereochemistry is shown for the centers, all enantiomers and diastereomers, individually or as a mixture, are encompassed by that structure. The methods for the determination of stereochemistry and the separation of stereoisomers are well-known in the art.
The compound according to the present disclosure may be present in unsolvated or solvated forms, including hydrate form. In general, the solvated forms are equivalent to unsolvated forms and both of them are encompassed within the scope of the present disclosure.
The present disclosure also encompasses any pharmaceutically acceptable derivative of the compounds according to formula (I) , e.g. ester, salt of the ester. A particularly preferable derivative is prodrug. Upon administration to a subject, such a derivative can directly or indirectly provide the compound according to the present disclosure or its metabolite or residue with pharmaceutical activity. A particularly preferable derivative (e.g. prodrug) is the compound, which upon administration to a subject, will increase bioavailability of the compound according to the present disclosure or improve delivery of the parent compound to the tissues or organs of a living body.

Beneficial Effect
The present compounds showed inhibitory effect to one or more FGFR enzymes and are useful in the treatment of FGFR-associated diseases, such as cancer. Particularly, the present compounds showed excellent inhibitory effect for FGFR4 over other FGFR enzymes, like FGFR1, FGFR2 and FGFR3.
Selective FGFR4 targeting has been shown to reduce adverse effects. and the simultaneous targeting of FGFR4 and other receptor tyrosine kinases (RTKs) has been shown to indirectly enhance anti-tumor activity through normalization of the tumor microenvironment. Currently, most FGFR inhibitors that are available to patients or in clinical trials are either pan-FGFR inhibitors with promiscuous kinome activity, such as ponatinib, or selective FGFR1-3 inhibitors. The lack of kinome selectivity invariably increases the possibility of off-target toxicity, whereas FGFR1-3 inhibitors cause soft-tissue mineralization and hyperphosphatemia (Dieci et al., Cancer Discovery, 2013, 3, 264-279) . Therefore, selective FGFR4 inhibitors would offer a preferred alternative for patient care.
The compound (s) according to the present disclosure show significant inhibitory effect on growth of cells dependent on FGFR signaling (especially FGFR4) , thereby showing a great effect on relevant FGFR-associated proliferative disorder. As can be seen from the Examples, the present compound (s) show a relatively low inhibitory effect on FGFR1, FGFR2 and/or FGFR3 while relatively high inhibitory effect on FGFR4 showing superior selectivity and safety and reducing the undesirable side effect.
The following examples are provided to further illustrate the embodiments of the present disclosure but are not intended to limit the scope of the present disclosure.

A series of bicyclic thio-urea derivatives of formula 1-7 can be prepared by the methods outlined in Scheme 1. The 5-iodomethyleneuracil 1-3 can be obtained by halo-exchanging reaction of NaI with 5-chloromethyleneuracil 1-2 which can be prepared from 5-hydromethyleneuracil 1-1 upon treatment with chlorination reagent (e.g. PCl
3, POCl
3, SOCl
2, or (COCl)
2) . Reaction of 5-iodomethyleneuracil 1-3 with suitable aniline 1-4 can yield the corresponding chloro-amine derivative 1-5 which can be transformed into bicyclic chloride derivative 1-7 by reaction with a suitable thiocyanate ester 1-6 under basic conditions (e.g., Cs
2CO
3, NaH, LiHMDS, NaHMDS, KHMDS or KOBu-t) .
Scheme 1
A series of bicyclic thio-urea derivatives of formula 2-4 can be prepared by the methods outlined in Scheme 2. Reduction of ester 2-1 can afford the corresponding aldehyde 2-2 by using diisobutylalumium hydride (DIBAL) . Reductive amination of the aldehyde 2-2 with suitable aniline can yield the corresponding chloro-amine derivative 2-3 by using suitable reductive reagent (e.g., NaBH
4, NaBH
3 (CN) or NaBH (OAc)
3) . The chloro-amine derivative 2-3 can be transformed into bicyclic thio-urea derivative 2-4 by reaction with a suitable thiocyanate ester as those desired in Scheme 1. Alternatively, Buchwald-Hartwig reaction or Ullmann reaction of 2-3 with an appropriate amine R
11NH

Biological Examples
Example A FGFR Enzymatic Assay
The inhibitor potency of the exemplified compounds was measured in Mobility shift assay with ATP (Sigma, Cat. No. A7699-1G) concentration at Km.
The compounds were diluted to 50X of the final desired highest inhibitor concentration in reaction by 100%DMSO. 100 μl of this compound dilution was transferred to a well in a 96-well plate. Then the compounds were serially diluted in DMSO by 3-fold for a total of 10 concentrations. 100 μl of 100%DMSO was added to two empty wells for no compound control (DMSO control) and no enzyme control (low control) in the same 96-well plate (Corning, 3365) . This plate was marked as source plate. 10 μl of compound was transferred from source plate to a new 96-well plate as the intermediate plate. 90 μl of 1x kinase buffer was added to each well of the intermediate plate. The compounds were mixed in the intermediate plate for 10 min on shaker. 5μl of diluted compounds in each well from the 96-well intermediate plate was transferred to a 384-well plate as assay plate in duplicates. 10μl of 2.5x enzyme solution (prepared in 1x kinase base buffer, i.e. 50 mM HEPES, pH 7.5; 0.0015%Brij-35) was added to each well of the 384-well (Corning, 3573) assay plate and incubate at room temperature for 10 min. Then 10μl of 2.5x peptide solution (FAM-labeled peptide and ATP added in the 1x kinase base buffer) was added to each well of the 384-well assay plate. The plate was incubated at 28℃for a period of time and 30μl of stop buffer (100 mM HEPES, pH 7.5; 0.015%Brij-35; 0.2%Coating Reagent #3; 50 mM EDTA) was added to stop reaction.
Data was collected by Caliper reading and analyzed in XLfit excel add-in version 5.0.4.8. Percent inhibition was calculated as (max-conversion) / (max-min) *100, “max” stands for DMSO control; “min” stands for low control. The IC
50 values were derived by fitting the data to the equation:
Y=Bottom + (Top-Bottom) / (1+ (IC
50/X) ^HillSlope) .
The compounds of the present disclosure were found to be effective inhibitors of one or more of FGFR1, FGFR2, and FGFR3 according to the above-described assay. IC
50 data is provided below in Table 1. The symbol “++++” indicates an IC
50 < 20 nM, the symbol “+++” indicates an IC
50 of 20 to <100 nM, “++” indicates an IC
50 of 100 to <500 nM, and the symbol “+” indicates an IC
50 ≥ 500 nM, “NT” indicates not test.

Example B FGFR Cell Proliferation/Survival Assays
The ability of the compounds to inhibit the growth of cells dependent on FGFR signaling for survival was measured using Growth inhibition assays (CellTiter-Glo, Promega, G7570) . Several cell lines (JHH-7 (cobioer biosciences, Cat#CPB60204) , HEP3B (cobioer biosciences, Cat#CPB60197) , Huh7 (cobioer biosciences, Cat#CPB60202) ) were used in cell proliferation assays, and compounds are screened for their ability to inhibit cell proliferation/survival.
Cells were seeded into the Nunc microwell-96 plates (Thermo, 165305) at appropriate cell density in 90ul cell culture media containing 10%FBS (JHH7 2000 cells/well; HEP3B 1500 cells/well; Huh7 2000 cells/well) . Cells were treated with 10 ul of 10X concentrations of serially diluted compounds (serially diluted by 1: 2 ratio for a total of 9 concentrations and the final concentration of DMSO is 0.1%) to a final volume of 100 uL/well. After 72-hour incubation, 100 uL of Cell Titer
reagent (Promega Corporation) that measures cellular ATP levels was added to each well. After 20-minute incubation with shaking, the luminescence was read on a plate reader.
The luminescent readings were converted to percent inhibition relative to DMSO treated control wells, and the IC50 values were calculated using GraphPad Prism 8 software by fitting the data to the equation for a log (inhibitor) vs. normalized response --Variable slope.
Results are shown in Table 2. The symbol “++++” indicates an IC
50 < 20 nM, the symbol “+++” indicates an IC
50 of 20 to < 100 nM, “++” indicates an IC
50 of 100 to < 500 nM, and the symbol “+” indicates an IC
50 ≥ 500 nM , “NT” indicates not test.
