     TECHNICAL FIELD OF THE INVENTION 
     The present invention relates to compounds and methods useful for inhibition of Transcriptional Enhancer Associate Domain (TEAD). The invention also provides pharmaceutically acceptable compositions comprising compounds of the present invention and methods of using said compositions in the treatment of various diseases, disorders, and conditions as described herein. 
     BACKGROUND OF THE INVENTION 
     Yes-associated protein (YAP) and transcriptional co-activator with PDZ-binding motif (TAZ) are transcriptional co-activators of the Hippo pathway network and regulate cell proliferation, migration, and apoptosis. Inhibition of the Hippo pathway promotes YAP/TAZ translocation to the nucleus, wherein YAP/TAZ interact with TEAD transcription factors and coactivate the expression of target genes and promote cell proliferation. Hyperactivation of YAP and TAZ and/or mutations in one or more members of the Hippo pathway network have been implicated in numerous cancers. 
     SUMMARY OF THE INVENTION 
     The Hippo signaling cascade is an important pathway for cancer biogenesis and tumor maintenance. The Hippo pathway is heavily mutated across many cancer indications through loss of function mutations in genes such as NF2. These pro-tumor mutations lead to the constitutive activation of the downstream transcriptional coactivators YAP and TAZ that drive the expression of many pro-survival and proliferation genes through the essential interaction with a TEAD protein family member. In addition, this unrestrained transcriptional program drives enhanced immune suppression in the tumor microenvironment. As described herein, to target this oncogenic pathway novel small molecule inhibitors were identified that selectively bind to TEAD and disrupt their interaction with YAP and TAZ, thereby downregulating YAP- and TAZ-dependent transcription. As demonstrated herein, these TEAD inhibitors prevent TEAD palmitoylation, which is critical for the interaction between YAP and TEAD. Furthermore, the TEAD inhibitors described herein inhibit in vitro proliferation of YAP-dependent (i.e., Hippo pathway-deficient cancer cell lines), but not Hippo pathway wild type cancer cell lines. Importantly, as shown herein, the TEAD inhibitor compounds of the present invention did not affect survival of a differentiated mouse podocyte cell line or compromise mouse kidney histology. Subsequent experiments in vivo demonstrate the TEAD inhibitors described herein downregulate YAP-dependent genes in human tumor xenografts after oral dosing. In addition, the TEAD inhibitors described herein exhibit single agent tumor growth inhibition of human tumor xenografts in mice at well tolerated oral doses. The data described herein demonstrate the ability of the small molecule TEAD inhibitors provided herein for targeting the Hippo pathway in cancers. 
     It has now been found that compounds of the present invention, and pharmaceutically acceptable compositions thereof, are effective as TEAD inhibitors. In one aspect, the present invention provides a compound of Formula I′: 
     
       
         
         
             
             
         
       
     
     or a pharmaceutically acceptable salt thereof, wherein each variable is as defined and described herein. In one aspect, the present invention provides a compound of Formula I: 
     
       
         
         
             
             
         
       
     
     or a pharmaceutically acceptable salt thereof, wherein each variable is as defined and described herein. 
     Compounds of the present invention, and pharmaceutically acceptable salts and compositions thereof, are useful for treating a variety of diseases, disorders or conditions associated with TEAD. Such diseases, disorders, or conditions include cellular proliferative disorders (e.g., cancer as described herein).

     As used herein, the term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, S. M. Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid or malonic acid or by using other methods used in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. 
     Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium and N + (C 1-4  alkyl) 4  salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, loweralkyl sulfonate and aryl sulfonate. 
     Unless otherwise stated, structures depicted herein are also meant to include all isomeric (e.g., enantiomeric, diastereomeric, and geometric (or conformational)) forms of the structure; for example, the R and S configurations for each asymmetric center, Z and E double bond isomers, and Z and E conformational isomers. Therefore, single stereochemical isomers as well as enantiomeric, diastereomeric, and geometric (or conformational) mixtures of the present compounds are within the scope of the invention. Unless otherwise stated, all tautomeric forms of the compounds of the invention are within the scope of the invention. Additionally, 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. For example, compounds having the present structures including the replacement of hydrogen by deuterium or tritium, or the replacement of a carbon by a  13 C- or  14 C-enriched carbon are within the scope of this invention. Such compounds are useful, for example, as analytical tools, as probes in biological assays, or as therapeutic agents in accordance with the present invention. In certain embodiments, a warhead moiety of a provided compound comprises one or more deuterium atoms. 
     As used herein, the terms “inhibitor” or “TEAD inhibitor” or “TEAD antagonist” are defined as a compound that binds to and/or inhibits TEAD with measurable affinity. In some embodiments, inhibition in the presence of the inhibitor is observed in a dose-dependent manner. In some embodiments, the measured signal (e.g., signaling activity or biological activity) is at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, at least about 99%, or at least about 100% lower than the signal measured with a negative control under comparable conditions. The potency of an inhibitor is usually defined by its IC 50  value (half maximal inhibitory concentration or concentration required to inhibit 50% of the agonist response). The lower the IC 50  value the greater the potency of the antagonist and the lower the concentration that is required to inhibit the maximum biological response. In certain embodiments, an inhibitor has an IC 50  and/or binding constant of less than about 100 μM, less than about 50 μM, less than about 1 μM, less than about 500 nM, less than about 100 nM, less than about 10 nM, or less than about 1 nM. 
     The terms “measurable affinity” and “measurably inhibit,” as used herein, means a measurable change or inhibition in TEAD activity between a sample comprising a compound of the present invention, or composition thereof, and TEAD, and an equivalent sample comprising TEAD, in the absence of said compound, or composition thereof.

     4. Uses, Formulation and Administration 
     Pharmaceutically Acceptable Compositions 
     According to another embodiment, the invention provides a pharmaceutical composition comprising a compound of this invention or a pharmaceutically acceptable derivative thereof and a pharmaceutically acceptable carrier, adjuvant, or vehicle. The amount of compound in compositions of this invention is such that is effective to measurably inhibit TEAD, or a variant or mutant thereof, in a biological sample or in a patient. In certain embodiments, the amount of compound in compositions of this invention is such that is effective to measurably inhibit TEAD, or a variant or mutant thereof, in a biological sample or in a patient. In certain embodiments, a composition of this invention is formulated for administration to a patient in need of such composition. In some embodiments, a composition of this invention is formulated for oral administration to a patient. 
     The terms “patient” or “subject” as used herein, means an animal, preferably a mammal, and most preferably a human. 
     The term “pharmaceutically acceptable carrier, adjuvant, or vehicle” refers to a non-toxic carrier, adjuvant, or vehicle that does not destroy the pharmacological activity of the compound with which it is formulated. Pharmaceutically acceptable carriers, adjuvants or vehicles that may be used in the compositions of this invention include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol and wool fat. 
     A “pharmaceutically acceptable derivative” means any non-toxic salt, ester, salt of an ester or other derivative of a compound of this invention that, upon administration to a recipient, is capable of providing, either directly or indirectly, a compound of this invention or an inhibitorily active metabolite or residue thereof. 
     As used herein, the term “inhibitorily active metabolite or residue thereof” means that a metabolite or residue thereof is also an inhibitor of TEAD, or a variant or mutant thereof. 
     Compositions of the present invention can be administered orally, parenterally, by inhalation spray, topically, rectally, nasally, buccally, vaginally or via an implanted reservoir. The term “parenteral” as used herein includes subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques. Preferably, the compositions are administered orally, intraperitoneally or intravenously. Sterile injectable forms of the compositions of this invention cancan be aqueous or oleaginous suspension. These suspensions cancan be formulated according to techniques known in the art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation cancan also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer&#39;s solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. 
     For this purpose, any bland fixed oil can be employed including synthetic mono- or diglycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions.

     Uses of Compounds and Pharmaceutically Acceptable Compositions 
     The Hippo Signaling Network 
     The Hippo signaling network (also known as the Salvador/Warts/Hippo (SWH) pathway) is a master regulator of cell proliferation, death, and differentiation. In some embodiments, the main function of the Hippo signaling pathway is to regulate negatively the transcriptional co-activators Yes-associated protein (YAP) and its paralogue, the transcriptional co-activator with PDZ-binding motif (TAZ; also known as WWTR1). The Hippo kinase cascade phosphorylates and inhibits YAP/TAZ by promoting its cytoplasmic retention and degradation, thereby inhibiting the growth promoting function regulated under the YAP/TAZ control. In an un-phosphorylated/de-phosphorylated state, YAP, also known as YAP1 or YAP65, together with TAZ, are transported into the nucleus where they interact with TEAD family of transcription factors to upregulate genes that promote proliferation and migration, and inhibit apoptosis. In some instances, unregulated upregulation of these genes involved in proliferation, migration, and anti-apoptosis leads to development of cancer. In some instances, overexpression of YAP/TAZ is associated with cancer. 
     Additional core members of the Hippo signaling pathway comprise the serine/threonine kinases MST1/2 (homologues of Hippo/Hpo in  Drosophila ), Lats1/2 (homologues of Warts/Wts), and their adaptor proteins Sav1 (homologue of Salvador/Sav) and Mob (MOBKL1A and MOBKL1B; homologues of Mats), respectively. In general, MST1/2 kinase complexes with the scaffold protein Sav1, which in turn phosphorylates and activates Lats1/2 kinase. Lats1/2 is also activated by the scaffold protein Mob. The activated Lats1/2 then phosphorylates and inactivates YAP or its paralog TAZ. The phosphorylation of YAP/TAZ leads to their nuclear export, retention within the cytoplasm, and degradation by the ubiquitin proteasome system. 
     In some instances, Lats1/2 phosphorylates YAP at the [HXRXXS] consensus motifs. YAP comprises five [HXRXXS] consensus motifs, wherein X denotes any amino acid residue. In some instances, Lats1/2 phosphorylates YAP at one or more of the consensus motifs. In some instances, Lats1/2 phosphorylates YAP at all five of the consensus motifs. In some instances, Lats1/2 phosphorylate at the S127 amino acid position. The phosphorylation of YAP S127 promotes 14-3-3 protein binding and results in cytoplasmic sequestration of YAP. Mutation of YAP at the S127 position thereby disrupts its interaction with 14-3-3 and subsequently promotes nuclear translocation. 
     Additional phosphorylation occurs at the S381 amino acid position in YAP. Phosphorylation of YAP at the S381 position and on the corresponding site in TAZ primes both proteins for further phosphorylation events by CK1δ/ε in the degradation motif, which then signals for interaction with the β-TRCP E3 ubiquitin ligase, leading to polyubiquitination and degradation of YAP. 
     In some instances, Lats1/2 phosphorylates TAZ at the [HXRXXS] consensus motifs. TAZ comprises four [HXRXXS] consensus motifs, wherein X denotes any amino acid residues. In some instances, Lats1/2 phosphorylates TAZ at one or more of the consensus motifs. In some instances, Lats1/2 phosphorylates TAZ at all four of the consensus motifs. In some instances, Lats1/2 phosphorylate at the S89 amino acid position. The phosphorylation of TAZ S89 promotes 14-3-3 protein binding and results in cytoplasmic sequestration of TAZ. Mutation of TAZ at the S89 position thereby disrupts its interaction with 14-3-3 and subsequently promotes nuclear translocation. 
     In some embodiments, phosphorylated YAP/TAZ accumulates in the cytoplasm, and undergoes SCF β-TRCP -mediated ubiquitination and subsequent proteasomal degradation. In some instances, the Skp, Cullin, F-box containing complex (SCF complex) is a multi-protein E3 ubiquitin ligase complex that comprises a F-box family member protein (e.g., Cdc4), Skp1, a bridging protein, and RBX1, which contains a small RING Finger domain which interacts with E2-ubiquitin conjugating enzyme. In some cases, the F-box family comprises more than 40 members, in which exemplary members include F-box/WD repeat-containing protein 1A (FBXW1A, βTrCP1, Fbxwl, hsSlimb, plkappaBalpha-E3 receptor subunit) and S-phase kinase-associated proteins 2 (SKP2). In some embodiments, the SCF complex (e.g., SCF βTrCP1 ) interacts with an E1 ubiquitin-activating enzyme and an E2 ubiquitin-conjugating enzyme to catalyze the transfer of ubiquitin to the YAP/TAZ substrate. Exemplary E1 ubiquitin-activating enzymes include those encoded by the following genes: UBA1, UBA2, UBA3, UBA5, UBA5, UBA7, ATG7, NAE1, and SAE1. Exemplary E2 ubiquitin-conjugating enzymes include those encoded by the following genes: UBE2A, UBE2B, UBE2C, UBE2D1, UBE2D2, UBE2D3, UBE2E1, UBE2E2, UBE2E3, UBE2F, UBE2G1, UBE2G2, UBE2H, UBE2I, UBE2J1, UBE2J2, UBE2K, UBE2L3, UBE2L6, UBE2M, UBE2N, UBE20, UBE2Q1, UBE2Q2, UBE2R1, UBE2R2, UBE2S, UBE2T, UBE2U, UBE2V1, UBE2V2, UBE2Z, ATG2, BIRC5, and UFC1. In some embodiments, the ubiquitinated YAP/TAZ further undergoes the degradation process through the 26S proteasome. 
     In some embodiments, the Hippo pathway is regulated upstream by several different families of regulators. In some instances, the Hippo pathway is regulated by the G-protein and its coupled receptors, the Crumbs complex, regulators upstream of the MST kinases, and the adherens junction. 
     YAP/TAZ Interaction with TEAD 
     In some embodiments, un-phosphorylated and/or dephosphorylated YAP/TAZ accumulates in the nucleus. Within the nucleus, YAP/TAZ interacts with the TEAD family of transcription factors (e.g., human TEAD1 (UniProt KB ID P28347-1 (SEQ ID NO: 1)), human TEAD2 (UniProtKB ID Q15562 (SEQ ID NO: 2)), human TEAD3 (UniProtKB ID Q99594 (SEQ ID NO: 3)), and human TEAD4 (UniProtKB ID Q15561 (SEQ ID NO: 4)) to activate genes involved in anti-apoptosis and proliferation, such as, for example, CTFG, Cyr61, and FGF1. 
     Proteomic and biochemical studies have shown that the TEAD (TEA Domain) transcription factors are palmitoylated at evolutionarily conserved cysteine residues. Three cysteine residues were found that are evolutionarily conserved and mutated to serine in human TEAD1 (C53S, C327S and C359S) to test whether the mutation affects TEAD1 palmitoylation. The C359S mutant showed the greatest loss of palmitoylation, and C327S and C53S also showed decreased palmitoylation. These results suggest that C359 plays a critical role in TEAD1 palmitoylation. Furthermore, combination mutation of all three cysteine residues, C53/327/359S (3CS), completely ablated TEAD1 palmitoylation, indicating that these residues are involved in TEAD1 palmitoylation. It has been found that TEADs undergo PAT-independent autopalmitoylation, under physiological concentrations of palmitoyl-CoA. Furthermore, autopalmitoylation plays critical roles in regulating TEAD-YAP association and their physiological functions in vitro and in vivo. Chan, et al. Nature Chem. Biol. 12, pages 282-289 (2016); Noland, et al. Structure, 24, 1-8 (2016); Gibault et al. J. Med. Chem. 61, 5057-5072 (2018). Therefore, palmitoylation of TEADs play important roles in regulating Hippo pathway transcriptional complexes.

     YAP/TAZ Regulation Mediated by G-Proteins/GPCRs 
     In some embodiments, the Hippo pathway is regulated by the G protein-coupled receptor (GPCR) and G protein (also known as guanine nucleotide-binding proteins) family of proteins. G proteins are molecular switches that transmit extracellular stimuli into the cell through GPCRs. In some instances, there are two classes of G proteins: monomeric small GTPases and heterotrimeric G protein complexes. In some instances, the latter class of complexes comprise of alpha (G α ), beta (G β ), and gamma (G γ ) subunits. In some cases, there are several classes of G α  subunits: G q/11 α, G 12/13 α, G i/o α (G inhibitory, G other), and G s α (G stimulatory). 
     In some instances, Giα (G inhibitory), G o α (G other), G q /11α, and G12/13α coupled GPCRs activate YAP/TAZ and promote nuclear translocation. In other instances, G s α (G stimulatory) coupled GPCRs suppress YAP/TAZ activity, leading to YAP/TAZ degradation. 
     In some cases, G i α (G inhibitory), G o α (G other), G q/11 α, and G 12/13 α coupled GPCRs activate YAP/TAZ through repression of Lats1/2 activities. In contrast, G s α, in some embodiments, induces Lats1/2 activity, thereby promoting YAP/TAZ degradation. 
     G q  Family 
     G q α (also known as G q/11  protein), participates in the inositol trisphosphate (IP 3 ) signal transduction pathway and calcium (Ca 2+ ) release from intracellular storage through the activation of phospholipase C (PLC). The activated PLC hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP 2 ) to diacyl glycerol (DAG) and IP 3 . In some instances, IP 3  then diffuses through the cytoplasm into the ER or the sarcoplasmic reticulum (SR) in the case of muscle cells, and then binds to inositol trisphosphate receptor (InsP3R), which is a Ca 2+  channel. In some cases, the binding triggers the opening of the Ca 2+  channel, and thereby increases the release of Ca 2+  into the cytoplasm. 
     In some embodiments, the GPCRs that interact with G q α include, but are not limited to, 5-hydroxytryptamine receptor (5-HT receptor) types 5-HT 2  and 5-HT 3 ; alpha-1 adrenergic receptor; vasopressin type 1 receptors 1A and 1B; angiotensin II receptor type 1; calcitonin receptor; histamine H1 receptor; metabotropic glutamate receptor, group I; muscarinic receptors M 1 , M 3 , and M 5 ; and trace amine-associated receptor 1. 
     In some instances, there are several types of G q α: G q , G q/11 , G q/14 , and G q/15 . The G q  protein is encoded by GNAQ. G q/11  is encoded by GNA11. G q/14  is encoded by GNA14. G q/15  is encoded by GNA15. 
     In some instances, mutations or modifications of the G q α genes have been associated with cancer. Indeed, studies have shown that mutations in G q α promote uveal melanoma (UM) tumorigenesis. In some instances, about 80% of UM cases have been detected to contain a mutation in GNAQ and/or GNA11. 
     In some instances, mutations or modifications of the G q α genes have been associated with congenital diseases. In some instances, mutations of G q α have been observed in congenital diseases such as Port-Wine Stain and/or Sturge-Weber Syndrome. In some instances, about 92% of Port-Wine stain cases harbors a mutation in GNAQ. In some instances, about 88% of Sturge-Weber Syndrome harbors a mutation in GNAQ. 
     G12/13 Family 
     G 12/13 α modulates actin cytoskeletal remodeling in cells and regulates cell processes through guanine nucleotide exchange factors (GEFs). GEFs participate in the activation of small GTPases which acts as molecular switches in a variety of intracellular signaling pathways. Examples of small GTPases include the Ras-related GTPase superfamily (e.g., Rho family such as Cdc42), which is involved in cell differentiation, proliferation, cytoskeletal organization, vesicle trafficking, and nuclear transport. 
     In some embodiments, the GPCRs that interact with G 12/13 α include, but are not limited to, purinergic receptors (e.g., P2Y 1 , P2Y 2 , P2Y 4 , P2Y 6 ); muscarinic acetylcholine receptors M1 and M3; receptors for thrombin [protease-activated receptor (PAR)-1, PAR-2]; thromboxane (TXA2); sphingosine 1-phosphate (e.g., S1P 2 , S1P 3 , S1P 4  and S1P 5 ); lysophosphatidic acid (e.g., LPA 1 , LPA 2 , LPA 3 ); angiotensin II (AT1); serotonin (5-HT 2c  and 5-HT 4 ); somatostatin (sst 5 ); endothelin (ET A  and ET B ); cholecystokinin (CCK 1 ); V 1a  vasopressin receptors; D 5  dopamine receptors; fMLP formyl peptide receptors; GAL 2  galanin receptors; EP 3  prostanoid receptors; A 1  adenosine receptors; α 1  adrenergic receptors; BB 2  bombesin receptors; B 2  bradykinin receptors; calcium-sensing receptors; KSHV-ORF74 chemokine receptors; NK 1  tachykinin receptors; and thyroid-stimulating hormone (TSH) receptors. 
     In some instances, G 12/13 α is further subdivided into G 12  and G 13  types which are encoded by GNA12 and GNA13, respectively.

     In some embodiments, the present invention provides a use of a compound, or a pharmaceutical salt or composition thereof, for treating one or more disorders, diseases, and/or conditions wherein the disorder, disease, or condition includes, but is not limited to, a cellular proliferative disorder. 
     The activity of a compound utilized in this invention as an inhibitor of TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4), or a variant or mutant thereof, can be assayed in vitro, in vivo or in a cell line. In vitro assays include assays that determine inhibition of TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4), or a variant or mutant thereof. Alternate in vitro assays quantitate the ability of the inhibitor to bind to TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4) or a variant or mutant thereof. Detailed conditions for assaying a compound utilized in this invention as an inhibitor of TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4), or a variant or mutant thereof, are set forth in the Examples below. See, for example, Examples 2 and 5. 
     As used herein, the terms “treatment,” “treat,” and “treating” refer to reversing, alleviating, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof, as described herein. In some embodiments, treatment can be administered after one or more symptoms have developed. In other embodiments, treatment can be administered in the absence of symptoms. For example, treatment can be administered to a susceptible individual prior to the onset of symptoms (e.g., in light of a history of symptoms and/or in light of genetic or other susceptibility factors). Treatment can also be continued after symptoms have resolved, for example, to prevent or delay their recurrence. 
     The provided compounds are inhibitors of TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4) and are therefore useful for treating one or more disorders associated with activity of TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4). Thus, in certain aspects and embodiments, the present invention provides a method for treating a TEAD-mediated disorder comprising the step of administering to a patient in need thereof a therapeutically effective compound of the present invention, or pharmaceutically acceptable composition thereof. 
     As used herein, the term “TEAD-mediated” disorders, diseases, and/or conditions as used herein means any disease or other deleterious condition in which TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4), or a variant or mutant thereof, is known to play a role. Accordingly, another aspect or embodiment of the present invention relates to treating or lessening the severity of one or more diseases in which TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4), or a variant or mutant thereof, are known to play a role. 
     As used herein, the term “a therapeutically effective amount of” refers to the amount of a TEAD inhibitor or a pharmaceutically acceptable salt thereof, which is effective to reduce or attenuate the biological activity of TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4) or a variant or mutant thereof, provide a therapeutic benefit in the treatment of a condition, or to delay or minimize one or more symptoms associated with the condition in a biological sample or in a patient. In some embodiments, “a therapeutically effective amount of” refers to the amount of a TEAD inhibitor or a pharmaceutically acceptable salt thereof that measurably decreases the binding or signaling activity of TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4), or a variant or mutant thereof or any TEAD-mediated activity. The term “therapeutically effective amount” can encompass, in some embodiments, an amount that improves overall therapy, reduces or avoids symptoms, signs, or causes of the condition, and/or enhances the therapeutic efficacy of another therapeutic agent. In certain embodiments, a therapeutically effective amount is an amount sufficient for inhibition of a TEAD transcription factor. In certain embodiments, a therapeutically effective amount is an amount sufficient for treating a proliferative disease. 
     In some aspects and embodiments, provided herein are methods of treating, reducing the severity of, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof of a disease or disorder characterized by or associated with increased TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4) expression and/or increased TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4) activity comprising the step of administering to a patient in need thereof a therapeutically effective compound of the present invention, or pharmaceutically acceptable composition thereof. In some aspects and embodiments, provided herein are methods of treating, reducing the severity of, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof of a disease or disorder in which inhibition or antagonizing of TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4) activity is beneficial comprising the step of administering to a patient in need thereof a therapeutically effective compound of the present invention, or pharmaceutically acceptable composition thereof. In some aspects and embodiments, provided herein are methods of treating, reducing the severity of, delaying the onset of, or inhibiting the progress of a disease or disorder, or one or more symptoms thereof of a disease or disorder in which inhibition or antagonizing of the Hippo pathway is beneficial comprising the step of administering to a patient in need thereof a therapeutically effective compound of the present invention, or pharmaceutically acceptable composition thereof. 
     In some aspects and embodiments, the present invention provides a method for treating one or more disorders, diseases, and/or conditions wherein the disorder, disease, or condition includes, but is not limited to, a cellular proliferative disorder, comprising administering to a patient in need thereof, a TEAD inhibitor compound as described herein, or a pharmaceutical salt or composition thereof. In some embodiments, a cellular proliferative disorder is cancer. In some embodiments, the cancer is characterized by increased TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4) expression and/or increased TEAD (e.g., TEAD1, TEAD2, TEAD3, and/or TEAD4) activity. 
     As used herein, the terms “increased,” “elevated,” or “enhanced,” are used interchangeably and encompass any measurable increase in a biological function and/or biological activity and/or a concentration. For example, an increase can be by at least about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 96%, about 97%, about 98%, about 99%, about 100%, about 2-fold, about 3-fold, about 4-fold, about 5-fold, about 6-fold, about 7-fold, about 8-fold, about 9-fold, about 10-fold, about 20-fold, about 25-fold, about 50-fold, about 100-fold, or higher, relative to a control or baseline amount of a function, or activity, or concentration. 
     As used herein, the terms “increased expression” and/or “increased activity” of a substance, such as TEAD, in a sample or cancer or patient refers to an increase in the amount of the substance, such as TEAD, of about 5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, about 96%, about 97%, about 98%, about 99%, about 100%, about 2-fold, about 3-fold, about 4-fold, about 5-fold, about 6-fold, about 7-fold, about 8-fold, about 9-fold, about 10-fold, about 20-fold, about 25-fold, about 50-fold, about 100-fold, or higher, relative to the amount of the substance, such as TEAD, in a control sample or control samples, such as an individual or group of individuals who are not suffering from the disease or disorder (e.g., cancer) or an internal control, as determined by techniques known in the art. A subject can also be determined to have an “increased expression” or “increased activity” of TEAD if the expression and/or activity of TEAD is increased by one standard deviation, two standard deviations, three standard deviations, four standard deviations, five standard deviations, or more, relative to the mean (average) or median amount of TEAD in a control group of samples or a baseline group of samples or a retrospective analysis of patient samples. As practiced in the art, such control or baseline expression levels can be previously determined, or measured prior to the measurement in the sample or cancer or subject, or can be obtained from a database of such control samples. 
     As used herein, a “proliferative disease” refers to a disease that occurs due to abnormal growth or extension by the multiplication of cells (Walker, Cambridge Dictionary of Biology, Cambridge University Press: Cambridge, UK, 1990). A proliferative disease can be associated with: 1) the pathological proliferation of normally quiescent cells; 2) the pathological migration of cells from their normal location (e.g., metastasis of neoplastic cells); 3) the pathological expression of proteolytic enzymes, such as the matrix metalloproteinases (e.g., collagenases, gelatinases, and elastases); or 4) the pathological angiogenesis as in proliferative retinopathy and tumor metastasis. Exemplary proliferative diseases include cancers (i.e., “malignant neoplasms”), benign neoplasms, angiogenesis, inflammatory diseases, and autoimmune diseases.

     The compounds and compositions, according to the methods of the present invention, can be administered using any amount and any route of administration effective for treating or lessening the severity of a cancer or tumor. The exact amount required varies from subject to subject, depending on the species, age, and general condition of the subject, the severity of the disease or condition, the particular agent, its mode of administration, and the like. Compounds of the invention are preferably formulated in dosage unit form for ease of administration and uniformity of dosage. The expression “dosage unit form” as used herein refers to a physically discrete unit of agent appropriate for the patient to be treated. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention is decided by the attending physician within the scope of sound medical judgment. The specific effective dose level for any particular patient or organism depends upon a variety of factors, including the disorder being treated and the severity of the disorder; the activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed, and like factors well known in the medical arts. The terms “patient” or “subject”, as used herein, means an animal, preferably a mammal, and most preferably a human. 
     Pharmaceutically acceptable compositions of this invention can be administered to humans and other animals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, as an oral or nasal spray, or the like, depending on the severity of the disease or disorder being treated. In certain embodiments, the compounds of the invention can be administered orally or parenterally at dosage levels of about 0.01 mg/kg to about 50 mg/kg and preferably from about 1 mg/kg to about 25 mg/kg, of subject body weight per day, one or more times a day, to obtain the desired therapeutic effect. 
     Liquid dosage forms for oral administration include, but are not limited to, pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethylformamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, and perfuming agents. 
     Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution, suspension or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer&#39;s solution, U.S.P. and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables. 
     Injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use. 
     In order to prolong the effect of a compound of the present invention, it is often desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the compound then depends upon its rate of dissolution that, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered compound form is accomplished by dissolving or suspending the compound in an oil vehicle. Injectable depot forms are made by forming microencapsule matrices of the compound in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of compound to polymer and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the compound in liposomes or microemulsions that are compatible with body tissues. 
     Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound. 
     Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents. 
     Solid compositions of a similar type can also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They can optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. Solid compositions of a similar type can also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like. 
     The active compounds can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch. Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions that can be used include polymeric substances and waxes. 
     Dosage forms for topical or transdermal administration of a compound of this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, and eye drops are also contemplated as being within the scope of this invention. Additionally, the present invention contemplates the use of transdermal patches, which have the added advantage of providing controlled delivery of a compound to the body. Such dosage forms can be made by dissolving or dispensing the compound in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate can be controlled by either providing a rate controlling membrane or by dispersing the compound in a polymer matrix or gel. 
     Co-Administration with One or More Other Therapeutic Agent(s) 
     Depending upon the particular condition, or disease, to be treated, additional therapeutic agents that are normally administered to treat that condition, can also be present in the compositions of this invention. As used herein, additional therapeutic agents that are normally administered to treat a particular disease, or condition, are known as “appropriate for the disease, or condition, being treated.” 
     In some embodiments, the present invention provides a method of treating a disclosed disease or condition comprising administering to a patient in need thereof an effective amount of a compound disclosed herein or a pharmaceutically acceptable salt thereof and co-administering simultaneously or sequentially an effective amount of one or more additional therapeutic agents, such as those described herein. In some embodiments, the method includes co-administering one additional therapeutic agent. In some embodiments, the method includes co-administering two additional therapeutic agents. In some embodiments, the combination of the disclosed compound and the additional therapeutic agent or agents acts synergistically. 
     A compound of the current invention can also be used in combination with known therapeutic processes, for example, the administration of hormones or radiation. In certain embodiments, a provided compound is used as a radiosensitizer, especially for the treatment of tumors which exhibit poor sensitivity to radiotherapy. 
     A compound of the current invention can be administered alone or in combination with one or more other therapeutic compounds, possible combination therapy taking the form of fixed combinations or the administration of a compound of the invention and one or more other therapeutic compounds being staggered or given independently of one another, or the combined administration of fixed combinations and one or more other therapeutic compounds. A compound of the current invention can besides, or in addition, be administered especially for tumor therapy in combination with chemotherapy, radiotherapy, immunotherapy, phototherapy, surgical intervention, or a combination of these. Long-term therapy is equally possible, as is adjuvant therapy in the context of other treatment strategies, as described above. Other possible treatments are therapy to maintain the patient&#39;s status after tumor regression, or even chemopreventive therapy, for example in patients at risk. 
     One or more other therapeutic agent(s) may be administered separately from a compound or composition of the invention, as part of a multiple dosage regimen. Alternatively, one or more other therapeutic agents agents(s) be part of a single dosage form, mixed together with a compound of this invention in a single composition. If administered as a multiple dosage regime, one or more other therapeutic agent(s) and a compound or composition of the invention can be administered simultaneously, sequentially or within a period of time from one another, for example within 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 18, 20, 21, 22, 23, or 24 hours from one another. In some embodiments, one or more other therapeutic agent(s) and a compound or composition of the invention are administered as a multiple dosage regimen within greater than 24 hours apart. 
     As used herein, the term “combination,” “combined,” and related terms refers to the simultaneous or sequential administration of therapeutic agents in accordance with this invention. For example, a compound of the present invention can be administered with one or more other therapeutic agent(s) simultaneously or sequentially in separate unit dosage forms or together in a single unit dosage form. Accordingly, the present invention provides a single unit dosage form comprising a compound of the current invention, one or more other therapeutic agent(s), and a pharmaceutically acceptable carrier, adjuvant, or vehicle. 
     The amount of a compound of the invention and one or more other therapeutic agent(s) (in those compositions which comprise an additional therapeutic agent as described above) that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. Preferably, a composition of the invention should be formulated so that a dosage of between 0.01-100 mg/kg body weight/day of a compound of the invention can be administered. 
     In those compositions which comprise one or more other therapeutic agent(s), the one or more other therapeutic agent(s) and a compound of the invention may act synergistically. Therefore, the amount of the one or more other therapeutic agent(s) in such compositions may be less than that required in a monotherapy utilizing only that therapeutic agent. In such compositions a dosage of between 0.01-1,000 μg/kg body weight/day of the one or more other therapeutic agent(s) can be administered. 
     The amount of one or more other therapeutic agent present in the compositions of this invention may be no more than the amount that would normally be administered in a composition comprising that therapeutic agent as the only active agent. Preferably the amount of one or more other therapeutic agent(s) in the presently disclosed compositions will range from about 50% to 100% of the amount normally present in a composition comprising that agent as the only therapeutically active agent. In some embodiments, one or more other therapeutic agent(s) is administered at a dosage of about 50%, about 55%, about 60%, about 65%, about 70%, about 75%, about 80%, about 85%, about 90%, or about 95% of the amount normally administered for that agent. As used herein, the phrase “normally administered” means the amount an FDA approved therapeutic agent is approvided for dosing per the FDA label insert. 
     The compounds of this invention, or pharmaceutical compositions thereof, may also be incorporated into compositions for coating an implantable medical device, such as prostheses, artificial valves, vascular grafts, stents and catheters. Vascular stents, for example, have been used to overcome restenosis (re-narrowing of the vessel wall after injury). However, patients using stents or other implantable devices risk clot formation or platelet activation. These unwanted effects may be prevented or mitigated by pre-coating the device with a pharmaceutically acceptable composition comprising a kinase inhibitor. Implantable devices coated with a compound of this invention are another embodiment of the present invention.

Upon antigen binding, such CARs link to endogenous signaling pathways in the effector cell and generate activating signals similar to those initiated by the TCR complex. 
     For example, in some embodiments the CAR-T cell is one of those described in U.S. Pat. No. 8,906,682 (June et al.; hereby incorporated by reference in its entirety), which discloses CAR-T cells engineered to comprise an extracellular domain having an antigen binding domain (such as a domain that binds to CD19), fused to an intracellular signaling domain of the T cell antigen receptor complex zeta chain (such as CD3 zeta). When expressed in the T cell, the CAR is able to redirect antigen recognition based on the antigen binding specificity. In the case of CD19, the antigen is expressed on malignant B cells. Over 200 clinical trials are currently in progress employing CAR-T in a wide range of indications. [https://clinicaltrials.gov/ct2/results?term=chimeric+antigen+receptors&amp;pg=1].

     Exemplary Immune Checkpoint Inhibitors 
     In some embodiments, an immuno-oncology agent is an immune checkpoint inhibitor as described herein. 
     The term “checkpoint inhibitor” as used herein relates to agents useful in preventing cancer cells from avoiding the immune system of the patient. One of the major mechanisms of anti-tumor immunity subversion is known as “T-cell exhaustion,” which results from chronic exposure to antigens that has led to up-regulation of inhibitory receptors. These inhibitory receptors serve as immune checkpoints in order to prevent uncontrolled immune reactions. 
     PD-1 and co-inhibitory receptors such as cytotoxic T-lymphocyte antigen 4 (CTLA-4, B and T Lymphocyte Attenuator (BTLA; CD272), T cell Immunoglobulin and Mucin domain-3 (Tim-3), Lymphocyte Activation Gene-3 (Lag-3; CD223), and others are often referred to as a checkpoint regulators. They act as molecular “gatekeepers” that allow extracellular information to dictate whether cell cycle progression and other intracellular signaling processes should proceed. 
     In some embodiments, an immune checkpoint inhibitor is an antibody to PD-1. PD-1 binds to the programmed cell death 1 receptor (PD-1) to prevent the receptor from binding to the inhibitory ligand PDL-1, thus overriding the ability of tumors to suppress the host anti-tumor immune response. 
     In one aspect, the checkpoint inhibitor is a biologic therapeutic or a small molecule. In another aspect, the checkpoint inhibitor is a monoclonal antibody, a humanized antibody, a fully human antibody, a fusion protein or a combination thereof. In a further aspect, the checkpoint inhibitor inhibits a checkpoint protein selected from CTLA-4, PDL1, PDL2, PD1, B7-H3, B7-H4, BTLA, HVEM, TIM3, GAL9, LAG3, VISTA, KIR, 2B4, CD160, CGEN-15049, CHK 1, CHK2, A2aR, B-7 family ligands or a combination thereof. In an additional aspect, the checkpoint inhibitor interacts with a ligand of a checkpoint protein selected from CTLA-4, PDL1, PDL2, PD1, B7-H3, B7-H4, BTLA, HVEM, TIM3, GAL9, LAG3, VISTA, KIR, 2B4, CD160, CGEN-15049, CHK 1, CHK2, A2aR, B-7 family ligands or a combination thereof. In an aspect, the checkpoint inhibitor is an immunostimulatory agent, a T cell growth factor, an interleukin, an antibody, a vaccine or a combination thereof. In a further aspect, the interleukin is IL-7 or IL-15. In a specific aspect, the interleukin is glycosylated IL-7. In an additional aspect, the vaccine is a dendritic cell (DC) vaccine. 
     Checkpoint inhibitors include any agent that blocks or inhibits in a statistically significant manner, the inhibitory pathways of the immune system. Such inhibitors may include small molecule inhibitors or may include antibodies, or antigen binding fragments thereof, that bind to and block or inhibit immune checkpoint receptors or antibodies that bind to and block or inhibit immune checkpoint receptor ligands.

     Example 2. TEAD inhibition Assay 
     TEAD inhibition can be assayed using Hippo Pathway TEAD Reporter—MCF7 Cell Line (BPS Bioscience, Catalog #: 60618). 
     Background 
     The Hippo pathway regulates cell proliferation and cell death. It is activated by high cell density and cell stress to stop cell proliferation and induce apoptosis. The mammalian Hippo pathway comprises MST kinases and LATS kinases. When the Hippo pathway is activated, MST kinases phosphorylate LATS kinases, which phosphorylate transcriptional co-activators YAP and TAZ. Unphosphorylated YAP and TAZ remain in nucleus and interact with TEAD/TEF transcriptional factors to turn on cell cycle-promoting gene transcription. However, when phosphorylated, YAP and TAZ are recruited from the nucleus to the cytosol, so that the YAP and TAZ-dependent gene transcription is turned off. Dysfunction of the Hippo pathway is frequently detected in human cancer and its down-regulation correlates with the aggressive properties of cancer cells and poor prognosis. 
     Description 
     The TEAD Reporter—MCF7 cell line contains the firefly luciferase gene under the control of TEAD responsive elements stably integrated into the human breast cancer cell line, MCF7. Inside the cells, basal unphosphorylated YAP/TAZ remains in the nucleus and induces the constitutive expression of luciferase reporter. The cell line is validated for the inhibition of the expression of luciferase reporter by the activators of the Hippo pathway. 
     Application

     To thaw the cells, it is recommended to quickly thaw the frozen cells from liquid nitrogen in a 37° C. water-bath, transfer to a tube containing 10 ml of Thaw Medium 1+Insulin (no Geneticin), spin down cells, resuspend cells in pre-warmed Thaw Medium 1+Insulin (no Geneticin), transfer resuspended cells to a T25 flask and culture in a CO 2  incubator at 37° C. overnight. The next day, replace the medium with fresh Thaw Medium 1+Insulin (no Geneticin), and continue growing culture in a CO 2  incubator at 37° C. until the cells are ready to be split. At first passage, switch to Growth Medium 1B+10 μg/ml of Insulin (includes Thaw Medium 1, Insulin, and Geneticin). Cells should be split before they reach complete confluence. 
     To passage the cells, rinse cells with phosphate buffered saline (PBS), and detach cells from the culture vessel with 0.25% Trypsin/EDTA. Add Growth Medium 1B+10 μg/ml of Insulin (Includes Thaw Medium 1, Insulin, and Geneticin) and transfer to a tube, spin down the cells, then, resuspend cells and seed appropriate aliquots of cell suspension into new culture vessels. Subcultivation ration: 1:5 to 1:10 weekly. 
     To freeze down the cells, rinse cells with phosphate buffered saline (PBS), and detach cells from culture vessel with Trypsin/EDTA. Add Growth Medium 1B+10 μg/ml of Insulin (Includes Thaw Medium 1, Insulin, and Geneticin) and transfer to a tube, spin down cells, and resuspend in freezing medium (10% DMSO+90% FBS).

     Example 3: Mouse Pharmacokinetics Study 
     Formulated compounds were administered intravenously or orally via gavage to BALB/c mice. Typically, at 0.167, 0.5, 1, 2, 4, 6, 12, and 24 hours post-dose, blood was collected and processed to plasma by centrifugation and stored at −80° C. until analysis. Internal standard was added to each sample prior to protein precipitation with acetonitrile or TCA. The precipitates were filtered through a filter plate and the samples were analyzed by LC/MS/MS. A standard curve was prepared in plasma from typically from 1.0 ng/mL to 3000 ng/mL and processed in the same manner as the samples. Sample analysis was typically performed on a suitable LC/MS/MS system fitted with an analytical UPLC column and compounds eluted from the analytical column with a gradient from 30-95% 0.1% formic acid (v/v) in ACN: 0.1% formic acid (v/v) in water. Mass spectrometric detection of test compound and the internal standard was performed by MRM in positive mode. The pharmacokinetics of each compound were analyzed by Phoenix WinNonlin software (Pharsight, St. Louis, Mo.) via noncompartmental analysis. Compounds in Table 3 were dosed in 5% DMS/95% PEG400 at 10 mg/kg by oral gavage with Cmax and AUC 0-last  summarized in Table 3.

     Example 4. CTGF Data Analysis 
     NU/NU nude female mice obtained from Charles River Laboratories and were subcutaneously injected with NCI-H226 (ATCC) human mesothelioma cells. Once tumors grew to an average size of 350-400 mm 3 , mice were randomized into each treatment group. NCI-H226 tumor bearing mice were treated by oral gavage with Vehicle (5% DMSO/95% PEG 400) or a TEAD inhibitor for a total of 3 administrations. 4 hours post-third administration, mice were euthanized and tumors were collected for isolation of RNA for pharmacodynamic (PD) analysis. 
     RNA was extracted from the tumors utilizing the QIAZOL (Qiagen) lysis reagent, tissues were then homogenized for 10 minutes using TissueLyser II (Qiagen). Once sample disruption and digestion was complete, chloroform was added to each sample, the homogenate was separated into aqueous and organic phases by centrifugation. 
     RNA was then isolated from samples using the KingFisher Flex automated extraction system and MagMAX mirvana total RNA isolation kit. Manufacturer&#39;s recommended protocol for high-throughput isolation of RNA from tissue samples was followed for RNA extraction. 
     Expression of the YAP/TEAD-regulated gene, CCN2 that encodes CTFG (Connective Tissue Growth Factor), and the housekeeping gene, human glyceraldehyde 3-phosphate dehydrogenase (GAPDH), were quantified by qRT-PCR analysis using the TaqMan Gene Expression Master Mix and TaqMan probes. CTGF and GAPDH cycle threshold (Ct) values for tumor cDNA samples were determined, and CTGF expression was normalized to GAPDH as an internal control. 
     The relative CTGF mRNA expression levels for each treatment group from tumor tissues were normalized to the vehicle control group. For comparisons between vehicle control and TEAD inhibitor treatment groups, an independent sample t-test was used for statistical analysis.

     Example 5. Anti-Proliferation Assay 
     Individual cell lines were grown in medium according to supplier instructions and seeded into 96-well plates at a density that ensured logarithmic growth over 72 hours. TEAD inhibitor compounds were administered to cells at a top concentration of 10 μm and subsequently a 10 point 3-fold serial dilution was conducted. After 72 hours, proliferation was quantified using Cell TITERGLO™ (Promega, Inc.) and compared to vehicle control. IC50 and EC50 values were generated using XLFit curve fitting software. 
       FIG.  2    demonstrates inhibition of cell growth of an NF2 mutant cell line by isomer 2 of compound I-12. The effect of isomer 2 of compound I-12 on cell proliferation is dependent on the presence of a Hippo/NF2 mutation. No effect is seen by isomer 2 of compound I-12 on the NF2 wild-type H28 cell line. 
       FIG.  3    shows anti-proliferative effects of isomer 2 of compound I-12 as evaluated in a 3-day Cell TITERGLO™ assay. The cell lines were chosen based on Cancer Dependency score and a sampling of known interacting oncogenes. Cell lines showing anti-proliferative effects following treatment with isomer 2 of compound I-12 and having EC50&lt;0.2 μM or &lt;1.0 μM are indicated by boxes. EC50 values were calculated from inflection points. 
     Example 6. In vivo Inhibition of Tumor Growth 
     NCI-11226 In Vivo Efficacy Studies 
     6-8 week old nu/nu nude mice (CRL) were inoculated subcutaneously with 5×106 NCI-H226 human mesothelioma tumor cells in the right flank. Tumor growth was monitored twice per week using vernier calipers and mean tumor volume (MTV) was calculated using the formula V=W2×L/2. 
     When the MTV reached approximately 150-200 mm 3 , animals were randomized into treatment groups (n=8-10/group) and dosed per os (PO) on a once everyday (QD) schedule for 27-40 days with either Vehicle (5% DMSO+95% PEG 400) or TEAD inhibitors, such as isomer 2 of compound I-12, and/or isomer 1 of compound I-186. 
     Randomization and treatments started on Day 0 and % Tumor Growth Inhibition was calculated on the last day of the study (when the control MTV reaches maximum allowable tumor volume), the following calculation was performed. 
       % TGI=100−[MTV treated/MTV control]×100
 
     Tumor growth and body weight change were measured twice per week. 
     For comparisons between vehicle control and TEAD inhibitor treatment groups, an independent sample t-test was used for statistical analysis.

No effects were observed on body weights throughout studies. Kidneys at end of studies showed no signs of damage by histopathology. 
     MSTO-211H In Vivo Efficacy Studies 
     6-8 week old SCID mice (CRL) were inoculated subcutaneously with 5×10 6  MSTO-211H human mesothelioma tumor cells in the right flank. Tumor growth was monitored twice per week using vernier calipers and mean tumor volume (MTV) was calculated using the formula V=W2×L/2. 
     When the MTV reached approximately 150-200 mm 3 , animals were randomized into treatment groups (n=6-8/group) and dosed per os (PO) on a once everyday (QD) schedule for 22-25 days with either Vehicle (5% DMSO+95% PEG 400) or TEAD inhibitors, such as compound I-27. 
     Randomization and treatments started on Day 0 and % Tumor Growth Inhibition was calculated on the last day of the study (when the control MTV reaches maximum allowable tumor volume), the following calculation was performed. 
       % TGI=100−[MTV treated/MTV control]×100
 
     Tumor growth and body weight change were measured twice per week.

       FIG.  7    demonstrates anti-tumor activities of isomer 2 of compound I-12 and isomer 1 of compound I-186 in an MSTO-211H mesothelioma xenograft model. No effects were observed on body weights throughout studies. Kidneys at end of studies showed no signs of damage by histopathology. 
     Example 7: TEAD Selectivity Assays 
     The TEAD targeting selectivity profiles of the TEAD inhibitor compounds described herein can be determined by either or both of two exemplary assays provided herein designed to monitor the interaction of TEAD isoforms or variants, e.g., human TEAD1 (UniProt KB ID P28347-1 (SEQ ID NO: 1)), human TEAD2 (UniProtKB ID Q15562 (SEQ ID NO: 2)), human TEAD3 (UniProtKB ID Q99594 (SEQ ID NO: 3)), and human TEAD4 (UniProtKB ID Q15561 (SEQ ID NO: 4), and YAP1 or TAZ. While co-immunoprecipitation techniques can be used to monitor protein-protein interactions, it is difficult to increase the throughput based on the basic methodology required. Accordingly, alternative but complementary assays are employed to monitor the interaction of the different TEAD isoforms or variants, e.g., human TEAD1 (UniProt KB ID P28347-1 (SEQ ID NO: 1)), human TEAD2 (UniProtKB ID Q15562 (SEQ ID NO: 2)), human TEAD3 (UniProtKB ID Q99594 (SEQ ID NO: 3)), and human TEAD4 (UniProtKB ID Q15561 (SEQ ID NO: 4), and YAP1 (or TAZ). 
     The first exemplary assay is an in vitro biochemical fluorescent polarization assay using recombinantly expressed and purified YAP-binding domains of individual TEAD isoforms and a fluorescently labeled peptide derived from the primary sequence of YAP1. (Bum-Erdene et al., Cell Chem Biol. 2019 Mar. 21; 26(3):378-389.e13, the contents of which are herein incorporated by reference in their entireties). Compounds are incubated with individual TEAD isoform proteins and the fluorescent peptide and potency is determined by quantifying the displacement of the peptide. 
     The second exemplary assay is a cell-based assay employing the split luciferase reporter system (Hall et al., ACS Chem. Biol. 2012, 7, 11, 1848-1857, the contents of which are herein incorporated by reference in their entireties). Briefly, the YAP-binding domain of each TEAD isoform is transiently co-expressed with the TEAD-binding domain or either YAP1 or TAZ in HEK293 cells and the proximity of the two chimeric gene fusion products is monitored by luciferase activity (Nouri et al. Cancers (Basel), 2019 Oct. 19; 11(10), the contents of which are herein incorporated by reference in their entireties). Compounds that interfere with the interaction of a TEAD isoform and YAP1 (or TAZ) decrease the resulting luciferase activity relative to vehicle treated controls. Similar in process to the fluorescent polarization assay, these chimeric gene fusions are recombinantly expressed in bacteria or insect cells and employed as an in vitro biochemical assay with a similar luciferase readout as the cell-based assay. 
     Example 8. Inhibition of Malignant Mesothelioma Tumor Cell Growth 
     The tumor cell growth inhibitory activity of the TEAD inhibitors described herein is evaluated in NCI-H2052 mesothelioma cell line harboring a NF2 mutation. This cell line is selected, in part, based on its mutational status and the ability of a siRNA directed against YAP, TAZ or TEAD1-TEAD4 to inhibit cell proliferation. The nuclear localization of YAP at confluence is also taken into account. 10,000 cells/well were plated in a 96-well black plate with clear flat bottom TC-Treated Imaging plate in regular medium with serum, which was replaced the day after with starvation medium containing 1% serum. After one day growth in the starvation medium, cells are incubated with TEAD inhibitor compounds. The starting concentration is 30 μM and serial dilutions in DMSO and medium are performed until 0.1 μM to achieve a final DMSO concentration of 0.5%. The cells are then allowed to grow for 3 days, and then, EdU (Invitrogen, Molecular Probe) is added in each well at a final concentration of 10 μM and the cells are returned to the incubator for an additional 24 h. The starvation medium is removed and 100 μl of PFA 4% containing Hoechst dye is added in each well to fix the cells. Plates are then incubated at room temperature for 15 min, washed twice with PBS, and the cells permeabilized by adding 100 μl per well of triton-100 containing 0.3% BSA. After 20 min, cells are washed with PBS and EdU detection is performed according to the instructions of the manufacturer. Image acquisition is performed, for example, using the ImageXpress Micro and analyzed using the MetaXpress software (Molecular Device).
