[0002] This application claims the benefit of U.S. Provisional Application No. 63 / 269.733, filed on March 22, 2022, which is incorporated herein by reference in its entirety. Background Art
[0003] Initially discovered from fly organ overgrowth screens, the conserved Hippo pathway controls cell proliferation, organ size, and stemness in most mammalian tissues. 1 At its core, the Hippo pathway consists of a linear kinase cascade in which extracellular signals (such as cell density and matrix stiffness) lead to the activation of the kinases MST1 / 2 (serine / threonine-protein kinase 4 (STK4, known as MST1) and serine / threonine-protein kinase 3 (STK3, known as MST2) as well as LATS1 / 2 (large tumor suppressor kinase 1 and large tumor suppressor kinase 2). 2 Phosphotransfer through MST1 / 2 and LATS1 / 2 leads to phosphorylation and cytoplasmic sequestration of Yesassociated protein 1 (YAP1, referred to throughout as YAP). YAP is a transcriptional coactivator that, through its interaction with TEA domain family proteins (TEAD: genes TEAD1, TEAD2, TEAD3, and TEAD4), promotes pro-proliferative transcriptional programs that lead to cell expansion. 3
[0004] As YAP is central to growth control, several cancer types harbor mutations that inactivate members of the Hippo pathway, leading to constitutive activation of YAP and uncontrolled cell proliferation. 4 For example, YAP-activating mutations are present in more than 70 percent of all malignant pleural mesothelioma (MPM). 5 YAP additionally promotes immune evasion in solid tumors by directly regulating the transcription of PD-L1 as well as TNF-a, CXCL6, CCL2, and CSF1, which promotes M2 macrophage polarization and the accumulation of tumor-resident myeloid-derived suppressor cells (MDSCs). 6-8 In addition to controlling “tumor-intrinsic” processes, YAP also promotes the expression of T regulatory cells (T reg) and inhibit the activation of CD4 and CD8 positive tumor-reactive T cells. 9,10 Although these data suggest that inhibition of YAP has high therapeutic utility in oncology and immuno-oncology indications, YAP does not possess a druggable protein domain. Summary of the invention
[0005] To address these deficiencies, among others, the present disclosure provides potent small molecule inhibitors of TEA domain family proteins (TEADs), which are DNA-binding transcription factors that allow locus-specific localization of YAP at TEAD-binding elements in the genome. 11 Each of the inhibitors is a compound of formula (I), a tautomer or a pharmaceutically acceptable salt thereof:

[0018] The compounds of the present disclosure are potent inhibitors of TEAD and are therefore useful as therapeutic agents for treating oncology and immuno-oncology indications in multiple embodiments. The need in the art is to develop treatments that affect the intrinsic growth process of tumors and simultaneously activate the adaptive immune response to tumors. The compounds of the present disclosure target TEAD family transcription factors and thereby achieve two desired activities by inhibiting the growth-promoting activity of the transcriptional coactivator YAP and by promoting the activation of multiple tumor-reactive T cell populations. Therefore, the compounds have robust utility in treating multiple tumor types.
[0019] The compounds engender many advantages. First, compared to known TEAD inhibitors, the compounds of formula (I) of the present disclosure have lower molecular weight and lower hydrophobicity. In this context, some known covalent inhibitors are characterized by electrophilic targeting groups (e.g., acrylamide) directly bound to the aromatic moiety, which increases the electrophilicity of such covalent targeting groups: this structural combination results in reduced selectivity of the inhibitor for TEAD. In contrast, the electrophilicity of the compounds of the present disclosure that conform to formula (I) is lower. The second advantage is that it was unexpectedly found that, as illustrated by the following examples, the compounds of the present disclosure inhibit cancer cell growth by selectively inhibiting TEAD: the use of covalent drugs to target TEAD is to improve the tolerability and safety of the compound, because lower doses of the compound are required to inactivate TEAD, especially in view of the long half-life of the compound in the cell (e.g., >24 hours).

The compounds may also exist in one or more tautomeric forms (including both single tautomers and mixtures of tautomers). The term "isomer" is intended to encompass all isomeric forms of the compounds of the present disclosure, including tautomeric forms of the compounds. The compounds of the present disclosure may also exist in open-chain or cyclized forms. In some cases, one or more of the cyclized forms may be produced by dehydration. The specific composition of the open-chain and cyclized forms may depend on how the compounds are separated, stored, or applied. For example, the compound exists primarily in an open-chain form under acidic conditions, but cyclizes under neutral conditions. All forms are included in the disclosure.
[0314] Some compounds described herein may have asymmetric centers and therefore exist in different enantiomeric and diastereomeric forms. Compounds as described herein may be in the form of optical isomers or diastereomers. Therefore, the present disclosure encompasses compounds and uses thereof in the form of optical isomers, diastereomers, and mixtures thereof (including racemic mixtures) as described herein.

[0315] Unless otherwise indicated, the term "stereoisomer" means one stereoisomer of a compound that is substantially free of other stereoisomers of the compound. Thus, a stereomerically pure compound having one chiral center will be substantially free of the opposite enantiomer of the compound. A stereomerically pure compound having two chiral centers will be substantially free of other diastereomers of the compound. A typical stereoisomerically pure compound contains greater than about 80% by weight of one stereoisomer of the compound and less than about 20% by weight of the other stereoisomers of the compound, such as greater than about 90% by weight of one stereoisomer of the compound and less than about 10% by weight of the other stereoisomers of the compound, or greater than about 95% by weight of one stereoisomer of the compound and less than about 5% by weight of the other stereoisomers of the compound, or greater than about 97% by weight of one stereoisomer of the compound and less than about 3% by weight of the other stereoisomers of the compound, or greater than about 99% by weight of one stereoisomer of the compound and less than about 1% by weight of the other stereoisomers of the compound. The stereoisomers described above can be considered as compositions containing two stereoisomers present in their respective weight percentages as described herein.
[0316] If there is a discrepancy between a structure shown and a name given to that structure, the structure shown shall prevail. In addition, if the stereochemistry of a structure or portion of a structure is not indicated by, for example, bold or dashed lines, the structure or portion of a structure should be interpreted as encompassing all stereoisomers thereof. However, in some cases, where there is more than one chiral center, the structure and name may be indicated as a single enantiomer to help describe the relevant stereochemistry. One skilled in the art of organic synthesis will know whether a compound is prepared as a single enantiomer by the process used to prepare it.
[0317] As used herein, and unless otherwise indicated to the contrary, the term "compound" is inclusive in that it encompasses a compound or a pharmaceutically acceptable salt, stereoisomer and / or tautomer thereof. Thus, for example, a compound of formula I includes pharmaceutically acceptable salts of tautomers of the compound.
[0318] In the present disclosure, a "pharmaceutically acceptable salt" is a pharmaceutically acceptable organic or inorganic acid or base salt of a compound described herein.

A pharmaceutically acceptable salt may have more than one charged atom in its structure. In this case, the pharmaceutically acceptable salt may have multiple counterions. Thus, a pharmaceutically acceptable salt may have one or more charged atoms and / or one or more counterions.
[0319] The term "treat" and its variations refer to the improvement or eradication of a disease or symptoms associated with a disease. In various embodiments, the term refers to minimizing or slowing the spread, progression or worsening of such a disease as a result of administering one or more of the preventive or therapeutic compounds described herein to a patient suffering from the disease.

[0435] In another aspect, also contemplated are pharmaceutical compositions suitable for a single unit dose, comprising a compound of the present disclosure, or a pharmaceutically acceptable stereoisomer, salt, or tautomer thereof, and a pharmaceutically acceptable carrier.
[0436] Compositions of the present disclosure suitable for oral use can be prepared according to any method known in the art for preparing pharmaceutical compositions. For example, liquid formulations of compounds of the present disclosure include one or more agents selected from sweeteners, flavoring agents, coloring agents, and preservatives to provide pharmaceutically palatable formulations of compounds of the present disclosure.
[0437] For tablet compositions, the compounds of the present disclosure are mixed with non-toxic pharmaceutically acceptable excipients for preparing tablets. Examples of such excipients include, but are not limited to, inert diluents such as calcium carbonate, sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating agents and disintegrants such as corn starch or alginic acid; binders such as starch, gelatin or gum arabic, and lubricants such as magnesium stearate, stearic acid or talc. Tablets may be uncoated or may be coated by known coating techniques to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained therapeutic effect over a desired period of time. For example, time-delayed substances such as glyceryl monostearate or glyceryl distearate may be used.
[0438] Formulations for oral use may also be presented as hard gelatin capsules in which the active ingredient is mixed with an inert solid diluent (e.g., calcium carbonate, calcium phosphate or kaolin), or as soft gelatin capsules in which the active ingredient is mixed with water or an oil medium (e.g., peanut oil, liquid paraffin or olive oil).
[0439] For aqueous suspensions, the compounds of the present disclosure are mixed with excipients suitable for maintaining a stable suspension. Examples of such excipients include, but are not limited to, sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, tragacanth gum, and gum arabic.
[0440] Oral suspensions may also include dispersants or wetting agents, such as naturally occurring phosphatides, such as lecithin, or condensation products of alkylene oxides with fatty acids, such as polyoxyethylene stearate, or condensation products of ethylene oxide with long-chain fatty alcohols, such as 17-carbon ethyleneoxy hexadecanol, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol, such as polyoxyethylene sorbitol monooleate, or condensation products of ethylene oxide with partial esters derived from fatty acids and hexitol anhydrides, such as polyethylene sorbitan monooleate. Aqueous suspensions may also include one or more preservatives, such as ethyl p-hydroxybenzoate or n-propyl p-hydroxybenzoate, one or more coloring agents, one or more flavoring agents, and one or more sweeteners, such as sucrose or saccharin.
[0441] Oily suspensions can be formulated by suspending a compound of the disclosure in a vegetable oil (e.g., peanut oil, olive oil, sesame oil, or coconut oil) or in a mineral oil (e.g., liquid paraffin). The oily suspensions may contain a thickening agent such as beeswax, hard paraffin, or cetyl alcohol.
[0442] Sweetening agents such as those set forth above, and flavoring agents may be added to provide a palatable oral preparation. These compositions may be preserved by the addition of an antioxidant such as ascorbic acid.
[0443] Dispersible powders and granules suitable for preparing aqueous suspensions by adding water provide a compound of the disclosure mixed with a dispersant or wetting agent, a suspending agent and one or more preservatives. Suitable dispersants or wetting agents and suspending agents are exemplified by those already mentioned above. Additional excipients such as sweeteners, flavoring agents and coloring agents may also be present.
[0444] The pharmaceutical composition of the present disclosure can also be in the form of an oil-in-water emulsion. The oil phase can be a vegetable oil (e.g., olive oil or peanut oil), or a mineral oil (e.g., liquid paraffin), or a mixture of these. Suitable emulsifiers can be naturally occurring gums (e.g., gum arabic or tragacanth), naturally occurring phospholipids (e.g., soybean, lecithin), and esters or partial esters derived from fatty acids and hexitol anhydrides (e.g., condensation reaction products of sorbitan monooleate and the partial ester with ethylene oxide (e.g., polyoxyethylene sorbitan monooleate)). Emulsions can also include sweeteners and flavoring agents.
[0445] Syrups and elixirs may be formulated with sweetening agents, for example glycerol, propylene glycol, sorbitol or sucrose. Such preparations may also contain a demulcent, a preservative and flavoring and coloring agents.
[0446] The pharmaceutical composition can be in the form of a sterile injectable, aqueous suspension or oily suspension. The suspension can be prepared according to known techniques using those suitable dispersants or wetting agents and suspending agents mentioned above. The sterile injection preparation can also be a sterile injectable solution or suspension in a nontoxic, parenterally acceptable diluent or solvent, such as a solution in 1,3-butanediol. In acceptable carriers and solvents, water, Ringer's solution and isotonic sodium chloride solution can be used. In addition, sterile fixed oils are generally used as solvents or suspending media. For this purpose, any mild fixed oil can be used, including synthetic monoglycerides or diglycerides. In addition, fatty acids (such as oleic acid) are found to be used to prepare injectables.
[0447] The compounds as described herein can also be administered in the form of suppositories for rectal administration of the drug. These compositions can be prepared by mixing the drug with a suitable non-irritating excipient that is solid at room temperature but liquid at rectal temperature and will therefore melt in the rectum to release the drug. Such substances include cocoa butter and polyethylene glycol.
[0448] Compositions for parenteral administration are administered in a sterile medium. Depending on the carrier used and the concentration (concentration of the drug in the preparation), parenteral preparations can be suspensions or solutions containing dissolved drugs. Excipients (e.g., local anesthetics, preservatives, and buffers) can also be added to parenteral compositions.

[0451] In some illustrative embodiments, the disease is selected from a brain tumor, gastric cancer, colorectal cancer, mesothelioma, non-small cell lung cancer, meningioma, head and neck cancer, and soft tissue sarcoma.
[0452] The compounds of the present disclosure are effective as monotherapeutic agents, for example, for the treatment of YAP-addicted cancers, including glioblastoma, head and neck squamous cell carcinoma, breast cancer, non-small cell lung cancer, melanoma, hepatocellular carcinoma, pancreatic adenocarcinoma, colorectal cancer, and prostate adenocarcinoma. According to the methods described herein, the compounds of the present disclosure can be administered with at least one additional chemotherapeutic agent. The additional chemotherapeutic agent can be administered before, after, or at the same time as the compounds of the present disclosure. Therefore, the compounds can be used as combination therapeutic agents because TEAD inhibition has been shown to produce synergistic effects when co-treated with other targeted therapies (e.g., EGFR inhibitors, MEK inhibitors, and ERK1 / 2 inhibitors). 15 Since YAP controls PD-L1 levels and reprograms the tumor microenvironment, TEAD inhibitors can be used as co-treatments with checkpoint inhibitors (e.g., PD-L1, PD1, and CTLA4 targeting antibodies).
[0453] In multiple embodiments, additional chemotherapeutic agents are selected from B-RAF inhibitors, epidermal growth factor receptor (EGFR) inhibitors, MEK inhibitors and immune checkpoint inhibitors.
