Definitions
- the present disclosure provides compounds useful as WEE1 degraders, pharmaceutical compositions comprising them, and their use in treating a disease or condition associated with WEE1 activity.
- WEE1 belongs to a family of protein kinases that phosphorylates the CDK1 and CDK2 cyclin-dependent kinases at their tyrosine-15 residue consequently inhibiting kinase activity and halting the cell cycle at the intra-Sand G2/M cell cycle checkpoints.
- cancer cells frequently rely solely upon the intra-Sand G2/M checkpoints because their G1 cell cycle checkpoint is disabled by various mechanisms.
- Tumors that rely heavily upon the WEE1-mediated intra-Sand G2/M checkpoints are hypothesized to be exceptionally sensitive to WEE1 loss and therapeutics that target WEE1 are expected to exhibit antitumor activity with a favorable therapeutic window.

Abstract
Described herein are WEE1 degraders and pharmaceutical compositions comprising the same. The subject compounds and compositions are useful for the treatment of a disease or condition associated with WEE1 activity, such as cancers.
Description
The present disclosure provides compounds useful as WEE1 degraders, pharmaceutical compositions comprising them, and their use in treating a disease or condition associated with WEE1 activity.
WEE1 belongs to a family of protein kinases that phosphorylates the CDK1 and CDK2 cyclin-dependent kinases at their tyrosine-15 residue consequently inhibiting kinase activity and halting the cell cycle at the intra-Sand G2/M cell cycle checkpoints. Compared to normal cells, cancer cells frequently rely solely upon the intra-Sand G2/M checkpoints because their G1 cell cycle checkpoint is disabled by various mechanisms. Tumors that rely heavily upon the WEE1-mediated intra-Sand G2/M checkpoints are hypothesized to be exceptionally sensitive to WEE1 loss and therapeutics that target WEE1 are expected to exhibit antitumor activity with a favorable therapeutic window. Previous drug development efforts resulted in clinical-stage WEE1 inhibitors. However, dose-limiting adverse events are major challenges for the clinical development of these WEE1 inhibitors due to their off-target effects on other protein kinases. Molecules with improved WEE1 protein targeting effect are desired.
Currently, targeted protein degradation is an emerging therapeutic strategy that exerts therapeutic effects by inducing the degradation of pathogenic target proteins. Molecular glue-induced protein degradation has attracted widespread interest in drug discovery. Molecular glue degraders induce or stabilize protein-protein interactions (PPIs) between ubiquitin ligases and target proteins (substrates) , leading to protein ubiquitination and subsequent proteasomal degradation.
There is a need for molecular glue degrader compounds that target WEE1 protein for degradation.

Definitions
In the following description, certain specific details are set forth in order to provide a thorough understanding of various embodiments. However, one skilled in the art will understand that the invention may be practiced without these details. In other instances, well-known structures have not been shown or described in detail to avoid unnecessarily obscuring descriptions of the embodiments. Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is, as “including, but not limited to. ” Further, the headings provided herein are for convenience only and do not interpret the scope or meaning of the claimed invention.
Reference throughout this specification to “some embodiments” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Also, as used in this specification and the appended claims, the singular forms “a, ” “an, ” and “the” include plural referents unless the content clearly dictates otherwise. It should also be noted that the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise.
The terms below, as used herein, have the following meanings, unless indicated otherwise.
Definitions of specific functional groups and chemical terms are described in more detail below. For purposes of this disclosure, the chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics, 75th Ed., inside cover, and specific functional groups are generally defined as described therein. Additionally, general principles of organic chemistry, as well as specific functional moieties and reactivity, are described in Organic Chemistry, Thomas Sorrell, 2nd Edition, University Science Books, Sausalito, 2006; Smith and March March’s Advanced Organic Chemistry, 6th Edition, John Wiley &Sons, Inc., New York, 2007; Larock, Comprehensive Organic Transformations, 3rd Edition, VCH Publishers, Inc., New York, 2018; Carruthers, Some Modern Methods of Organic Synthesis, 4th Edition, Cambridge University Press, Cambridge, 2004; the entire contents of each of which are incorporated herein by reference.
At various places in the present disclosure, linking substituents are described. Where the structure clearly requires a linking group, the Markush variables listed for that group are understood to be linking groups. For example, if the structure requires a linking group and the Markush group definition for that variable lists “alkyl” , then it is understood that the “alkyl” represents a linking alkylene group.
When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom in the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such formula. Combinations of substituents and/or variables are permissible, but only if such combinations result in stable compounds.
When any variable (e.g., Ri) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with 0-2 Ri moieties, then the group may optionally be substituted with up to two Ri moieties, and Ri at each occurrence is selected independently from the definition of Ri. Also, combinations of substituents and/or variables are permissible, but only if such combinations result in stable compounds.

Table 2 Exemplary Compounds
Compounds provided herein may exist in a number of different forms or derivatives.
In some embodiments, the compounds described herein exist as geometric isomers. In some embodiments, the compounds described herein possess one or more double bonds. The compounds presented herein include all cis, trans, syn, anti, entgegen (E) , and zusammen (Z) isomers as well as the corresponding mixtures thereof.
In some embodiments, the compounds described herein possess one or more chiral centers and each center exists in the R configuration, or S configuration. The compounds described herein include all diastereomeric, enantiomeric, and epimeric forms as well as the corresponding mixtures thereof. In additional embodiments of the compounds and methods provided herein, mixtures of enantiomers and/or diastereoisomers, resulting from a single preparative step, combination, or interconversion are useful for the applications described herein. In some embodiments, the compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compound with an optically active resolving agent to form a pair of diastereoisomeric compounds, separating the diastereomers and recovering the optically pure enantiomers. In some embodiments, the diastereomers have distinct physical properties (e.g., melting points, boiling points, solubilities, reactivity, etc. ) and are separated by taking advantage of these dissimilarities. In some embodiments, the diastereomers are separated by chiral chromatography, or preferably, by separation/resolution techniques based upon differences in solubility. In some embodiments, the optically pure enantiomer is then recovered, along with the resolving agent, by any practical means that would not result in racemization. The carbon-carbon bonds of the compounds provided may be depicted herein using a solid lineawedged bondahashed wedged bondabold bondor a hashed bondThe use of a solid line to depict bonds to asymmetric carbon atoms is meant to indicate that all possible stereoisomers (e.g., specific enantiomers, racemic mixtures, etc. ) at that carbon atom are included. The use of a wedged bondor a hashed wedged bondis meant to indicate absolute stereochemistry. The use of a bold bondor a hashed bondis meant to indicate relative stereochemistry.
In some embodiments, compounds provided herein may exist in different tautomeric forms, and all such forms are embraced within the scope of the present disclosure. The term “tautomer” or “tautomeric form” refers to structural isomers of different energies which are interconvertible via a low energy barrier. By way of examples, proton tautomers (also known as prototropic tautomers) include interconversions via migration of a proton, such as keto-enol, amide-imidic acid, lactam-lactim, imine-enamine isomerizations and annular forms where a proton can occupy two or more positions of a heterocyclic system. Valence tautomers include interconversions by reorganization of some of the bonding electrons. Tautomers can be in equilibrium or sterically locked into one form by appropriate substitution. Compounds of the present disclosure identified by name or structure as one particular tautomeric form are intended to include other tautomeric forms unless otherwise specified.
Unless otherwise stated, compounds provided herein may exhibit their natural isotopic abundance, or one or more of the atoms may be artificially enriched in a particular isotope having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number predominantly found in nature. All isotopic variations of the compounds of the present disclosure, whether radioactive or not, are encompassed within the scope of the present disclosure. For example, hydrogen has three naturally occurring isotopes, denoted 1H (protium) , 2H (deuterium) , and 3H (tritium) . Protium is the most abundant isotope of hydrogen in nature. Enriching for deuterium may afford some therapeutic advantages, such as increased in vivo half-life and/or exposure, or may provide a compound useful for investigating in vivo routes of drug elimination and metabolism.
For example, the compounds described herein may be artificially enriched in one or more particular isotopes. In some embodiments, the compounds described herein may be artificially enriched in one or more isotopes that are not predominantly found in nature. In some embodiments, the compounds described herein may be artificially enriched in one or more isotopes selected from deuterium (2H) , tritium (3H) , iodine-125 (125I) or carbon-14 (14C) . In some embodiments, the compounds described herein are artificially enriched in one or more isotopes selected from 2H, 11C, 13C, 14C, 15C, 12N, 13N, 15N, 16N, 16O, 17O, 14F, 15F, 16F, 17F, 18F, 33S, 34S, 35S, 36S, 35Cl, 37Cl, 79Br, 81Br, 131I, and 125I. In some embodiments, the abundance of the enriched isotopes is independently at least 1%, at least 10%, at least 20%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, or 100%by molar.
In some embodiments, the compound is deuterated in at least one position. In some embodiments, the compounds disclosed herein have some or all of the 1H atoms replaced with 2H atoms.
The methods of synthesis for deuterium-containing compounds are known in the art and include, by way of non-limiting example only, the procedure described in U.S. Patent Nos. 5,846,514 and 6,334,997, and the following synthetic methods. For example, deuterium substituted compounds may be synthesized using various methods such as described in: Dean, Dennis C.; Editor. Recent Advances in the Synthesis and Applications of Radiolabeled Compounds for Drug Discovery and Development. [In: Curr., Pharm. Des., 2000; 6 (10) ] 2000, 110 pp; George W.; Varma, Rajender S. The Synthesis of Radiolabeled Compounds via Organometallic Intermediates, Tetrahedron, 1989, 45 (21) , 6601-21; and Evans, E. Anthony. Synthesis of radiolabeled compounds, J. Radioanal. Chem., 1981, 64 (1-2) , 9-32.
Deuterated starting materials are readily available and are subjected to the synthetic methods described herein to provide for the synthesis of deuterium-containing compounds. Large numbers of deuterium-containing reagents and building blocks are available commercially from chemical vendors, such as Aldrich Chemical Co.
In some embodiments, the compounds described herein exist as their pharmaceutically acceptable salts. As used herein, the term “pharmaceutically acceptable salt” , unless otherwise indicated, includes salts that retain the biological effectiveness of the free acids and bases of the specified compound and that are not biologically or otherwise undesirable. Contemplated pharmaceutically acceptable salt forms include, but are not limited to, mono, bis, tris, tetrakis, and so on. Pharmaceutically acceptable salts are non-toxic in the amounts and concentrations at which they are administered. The preparation of such salts can facilitate the pharmacological use by altering the physical characteristics of a compound without preventing it from exerting its physiological effect. Useful alterations in physical properties include lowering the melting point to facilitate transmucosal administration and increasing the solubility to facilitate administering higher concentrations of the drug.
Pharmaceutically acceptable salts include acid addition salts such as those containing sulfate, chloride, hydrochloride, fumarate, maleate, phosphate, sulfamate, acetate, citrate, lactate, tartrate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate, cyclohexylsulfamate and quinate. Pharmaceutically acceptable salts can be obtained from acids such as hydrochloric acid, maleic acid, sulfuric acid, phosphoric acid, sulfamic acid, acetic acid, citric acid, lactic acid, tartaric acid, malonic acid, methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, cyclohexylsulfamic acid, fumaric acid, and quinic acid.
Pharmaceutically acceptable salts also include basic addition salts such as those containing benzathine, chloroprocaine, choline, diethanolamine, ethanolamine, t-butylamine, ethylenediamine, meglumine, procaine, aluminum, calcium, lithium, magnesium, potassium, sodium, ammonium, alkylamine, and zinc, when acidic functional groups, such as carboxylic acid or phenol are present. For example, see Remington’s Pharmaceutical Sciences, 19thed., Mack Publishing Co., Easton, PA, Vol. 2, p. 1457, 1995; “Handbook of Pharmaceutical Salts: Properties, Selection, and Use” by Stahl and Wermuth, Wiley-VCH, Weinheim, Germany, 2002. Such salts can be prepared using the appropriate corresponding bases.
Pharmaceutically acceptable salts can be prepared by standard techniques. For example, the free-base form of a compound can be dissolved in a suitable solvent, such as an aqueous or aqueous-alcohol solution containing the appropriate acid and then isolated by evaporating the solution. Thus, if the particular compound is a base, the desired pharmaceutically acceptable salt may be prepared by any suitable method available in the art, for example, treatment of the free base with an inorganic acid, such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid and the like, or with an organic acid, such as acetic acid, maleic acid, succinic acid, mandelic acid, fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid, salicylic acid, a pyranosidyl acid, such as glucuronic acid or galacturonic acid, an alpha-hydroxy acid, such as citric acid or tartaric acid, an amino acid, such as aspartic acid or glutamic acid, an aromatic acid, such as benzoic acid or cinnamic acid, a sulfonic acid, such as p-toluenesulfonic acid or ethanesulfonic acid, or the like.
Similarly, if the particular compound is an acid, the desired pharmaceutically acceptable salt may be prepared by any suitable method, for example, treatment of the free acid with an inorganic or organic base, such as an amine (primary, secondary or tertiary) , an alkali metal hydroxide or alkaline earth metal hydroxide, or the like. Illustrative examples of suitable salts include organic salts derived from amino acids, such as L-glycine, L-lysine, and L-arginine, ammonia, primary, secondary, and tertiary amines, and cyclic amines, such as hydroxyethylpyrrolidine, piperidine, morpholine or piperazine, and inorganic salts derived from sodium, calcium, potassium, magnesium, manganese, iron, copper, zinc, aluminum and lithium.
In some embodiments, the methods disclosed herein include methods of treating diseases by administering such pharmaceutically acceptable salts. In some embodiments, the methods disclosed herein include methods of treating diseases by administering such pharmaceutically acceptable salts as pharmaceutical compositions.

Activities for target protein degradation were determined by Western Blot assays in MOLT4. MOLT4 cells were seeded into 12-well plates at 1 million cells per well, then treated with test compounds for 6 hours at 0.1 μM or 0.5 μM. The treated cells were collected and lysed in RIPA buffer supplied with protease inhibitor (PMSF, Beyotime, Cat#: ST507) for SDS-PAGE. The protein levels of WEE1 and CK1αwere determined by specific WEE1 monoclonal antibody from CST (Cat#: 13084S) and specific CK1αmonoclonal antibody from Abcam (Cat#: ab108296) . The primary antibodies of WEE1 and CK1α were prepared with 5%bovine serum albumin (BSA) in TBST buffer at 1: 1000 dilution. The secondary antibody for WEE1 and CK1α primary antibodies was rabbit anti-goat IgG H&L and was prepared with 5%skimmed milk at 1: 2000 dilution. After SDS-PAGE and semi-dry transfer, the PVDF membranes were incubated in the prepared primary antibodies at 4 ℃ overnight. The PVDF membranes were taken from the primary antibodies after the incubation and washed with TBST buffer for 30 minutes. Then the PVDF membranes were incubated in the secondary antibodies at room temperature for 1 hour. Finally, the PVDF membranes were washed with TBST for 30 minutes followed by chemiluminescence signal measurement by ECL kit from Epizyme (SQ201) . The WEE1 and CK1α protein levels were evaluated based on the chemiluminescence signaling. The results are shown in Tables 3, 4A and 4B. All compounds disclosed herein exhibited effective WEE1 and CK1α degrading activity.

Cereblon binding of the compounds disclosed herein were measured by HTRF assay (Cisbio) . The HTRF assay was performed in OptiPlate-384 white plates with a total volume of 20 mL each well. 5 μL compounds (final con. of 1.6μM) were added to the plate with 5 μL Human WT GST-tagged Cereblon. Then 10 μL of HTRF detection reagents including 5 μL Anti-GST-Eu cryptate beads (donor) and 5 μL Thalidomide-Red labelled with XL665 (acceptor) were added to the mixture and incubated at room temperature for 3 hours. Compounds that compete with the Thalidomide in binding Cereblon can prevent energy transfer from donor to acceptor. The signals from the plates were detected by microplate reader (PerkinElmer, EnVision, USA) for optimal signal detection at 620 nm (donor) and 665 nm (acceptor) . The ratio of 665 nm/620 nm was calculated for each compound to indicate its Cereblon binding ability (the smaller the ratio suggests the better binding ability) . The results were shown in Table 5.
