The present application is concerned with pharmaceutically useful compounds. The disclosure provides new compounds as well as their compositions and methods of use. The compounds inhibit the autopalmitoylation of TEAD-transcription factors and are therefore useful in the treatment of diseases related to the activity of TEAD-transcription factors including, e.g., cancers and other diseases.
Hippo signaling plays key roles in organ size control and tumor suppression. The signal transduction involves a core kinase cascade, including MST1/2 and Lats1/2 kinases, leading to YAP/TAZ phosphorylation, cytoplasmic retention and inhibition3. Physiological or pathological inactivation of these kinases leads to YAP/TAZ dephosphorylation and nuclear accumulation. Subsequently, nuclear YAP/TAZ binds to the TEA domain transcription factors (TEAD1-4 in mammals, and Scalloped in Drosophila) to mediate the target genes expression. The TEAD-YAP complex regulates normal development of skin, muscle, lung and liver, and are also oncogenic factor amplified in many human cancers. TEADs can also bind to Vgll4, which has been implicated as a tumor suppressor by competing with YAP/TAZ for TEADs binding. Therefore, TEADs are essential in regulating the transcriptional output of Hippo pathway. Although targeting TEAD-YAP could be a promising therapeutic approach for diseases with deregulated Hippo pathway, it remains challenging to directly inhibit transcription factors with small molecules. Therefore, understanding the regulation of TEADs might reveal new therapeutic opportunities for drug discovery.
Post-translational S-palmitoylation attaches a 16-carbon palmitate to the cysteine residue through a reversible thioester bond. A large number of palmitoylated proteins have been identified through proteomic studies. Dynamic S-palmitoylation plays critical roles regulating the trafficking, membrane localization and functions of many proteins, including Src-family kinases, GTPases, and synaptic adhesion molecules. Asp-His-His-Cys (DHHC) family proteins are evolutionarily conserved protein palmitoyl acyltransferases (PATs), mediating enzymatic S-palmitoylation. In addition, some proteins could bind to palmitoyl-Coenzyme A (CoA) directly, and undergo PAT-independent autopalmitoylation. However, autopalmitoylation is poorly characterized. Most of the reported examples of autopalmitoylation are observed under non-physiological, high concentration of palmitoyl-CoA (>100 μM). To date, only a few proteins, including yeast transporter protein Bet3, are autopalmitoylated under physiological concentrations of palmitoyl-CoA (1-10 μM). Therefore, it is important to reveal additional autopalmitoylated proteins and to understand their regulations and functions.
The present disclosure provides, inter alia, a compound of Formula (I):
or a pharmaceutically acceptable salt thereof; wherein the variables are as defined below.
The present disclosure also provides a composition comprising a compound of Formula (I), or a pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable carrier.

The details of one or more embodiments are set forth in the description below. Other features, objects and advantages will be apparent from the description and from the claims.
For the terms “e.g.” and “such as,” and grammatical equivalents thereof, the phrase “and without limitation” is understood to follow unless explicitly stated otherwise.
The singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.
The term “about” means “approximately” (e.g., plus or minus approximately 10% of the indicated value).
The expressions, “ambient temperature” and “room temperature” (abbreviated “r.t.”) refer generally to a temperature, e.g., a reaction temperature, that is about the temperature of the room in which the reaction is carried out, e.g., a temperature from about 20° C. to about 30° C., typically about 25° C.
Through proteomic and biochemical studies, it has been identified that the TEAD transcription factors are palmitoylated at evolutionarily conserved cysteine residues. It has been found that TEADs undergo PAT-independent autopalmitoylation, under physiological concentrations of palmitoyl-CoA. The crystal structures of the lipid-bound TEADs, and revealed a new ligand-binding site in TEADs. Furthermore, autopalmitoylation plays critical roles in regulating TEAD-YAP association and their physiological functions in vitro and in vivo. Therefore, palmitoylation of TEADs plays important roles in regulating Hippo pathway transcriptional complexes.
The discovery of a new ligand-binding site in TEADs has allowed the discovery of small molecule inhibitors of TEAD autopalmitoylation. While not being bound by any theory, it is understood that the ligands bind to the palmitate-binding pocket, and inhibit TEAD-YAP interaction, cancer cell proliferation and migration. Therefore, direct inhibition of TEAD autopalmitoylation activities is useful to inhibit these oncogenic transcription factors.

It is further appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment (while the embodiments are intended to be combined as if written in multiply dependent form). Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, can also be provided separately or in any suitable subcombination. Thus, it is contemplated that features described as embodiments of the compounds of Formula (I) can be combined in any suitable combination.
At various places in the present specification, certain features of the compounds are disclosed in groups or in ranges. It is specifically intended that such a disclosure include each and every individual subcombination of the members of such groups and ranges. For example, the term “C1-6 alkyl” is specifically intended to individually disclose (without limitation) methyl, ethyl, C3 alkyl, C4 alkyl, C5 alkyl and C6 alkyl.
The term “n-membered,” where n is an integer, typically describes the number of ring-forming atoms in a moiety where the number of ring-forming atoms is n. For example, piperidinyl is an example of a 6-membered heterocycloalkyl ring, pyrazolyl is an example of a 5-membered heteroaryl ring, pyridyl is an example of a 6-membered heteroaryl ring and 1,2,3,4-tetrahydro-naphthalene is an example of a 10-membered cycloalkyl group. When the term is used to refer to a carbocyclic ring (e.g., aryl or cycloalkyl), all of the ring atoms are carbon atoms. When the term is used to refer to a heterocyclic ring (e.g., heteroaryl or heterocycloalkyl), one or more of the ring atoms (e.g., 1, 2, 3, or 4) are heteroatoms (e.g., nitrogen, oxygen or sulfur) and the remainder (e.g., n−1, n−2, n−3, or n−4) are carbon atoms.
At various places in the present specification, variables defining divalent linking groups are described. It is specifically intended that each linking substituent include both the forward and backward forms of the linking substituent. For example, —NR(CR′R″)n— includes both —NR(CR′R″)n— and —(CR′R″)nNR— and is intended to disclose each of the forms individually. Where the structure 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” or “aryl” then it is understood that the “alkyl” or “aryl” represents a linking alkylene group or arylene group, respectively.
The term “substituted” means that an atom or group of atoms formally replaces hydrogen as a “substituent” attached to another group. The term “substituted”, unless otherwise indicated, refers to any level of substitution, e.g., mono-, di-, tri-, tetra- or penta-substitution, where such substitution is permitted. The substituents are independently selected, and substitution may be at any chemically accessible position. It is to be understood that substitution at a given atom is limited by valency. The term “optionally substituted” means unsubstituted or substituted. The term “substituted” means that a hydrogen atom is removed and replaced by a substituent. A single divalent substituent, e.g., oxo, can replace two hydrogen atoms.
The term “Cn-m” indicates a range which includes the endpoints, wherein n and m are integers and indicate the number of carbons. Examples include C1-4, C1-6 and the like. Whenever the term is used intended to describe each member included in the group, Cn through Cm as if each had been explicitly set forth. For example, the term C1-6 is intended to describe each of the members C1, C2, C3, C4, C5 and C6.

The reactions for preparing compounds of the invention can be carried out in suitable solvents which can be readily selected by one of skill in the art of organic synthesis. Suitable solvents can be substantially non-reactive with the starting materials (reactants), the intermediates or products at the temperatures at which the reactions are carried out, e.g., temperatures which can range from the solvent's freezing temperature to the solvent's boiling temperature. A given reaction can be carried out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step, suitable solvents for a particular reaction step can be selected by the skilled artisan.
Preparation of compounds of the invention can involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. The chemistry of protecting groups is described, e.g., in Kocienski, Protecting Groups, (Thieme, 2007); Robertson, Protecting Group Chemistry, (Oxford University Press, 2000); Smith et al., March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, 6th Ed. (Wiley, 2007); Peturssion et al., “Protecting Groups in Carbohydrate Chemistry,” J. Chem. Educ., 1997, 74(11), 1297; and Wuts et al., Protective Groups in Organic Synthesis, 4th Ed., (Wiley, 2006).

When more than one pharmaceutical agent is administered to a patient, they can be administered simultaneously, sequentially, or in combination (e.g., for more than two agents).
When employed as pharmaceuticals, the compounds of the invention can be administered in the form of pharmaceutical compositions. Thus the present disclosure provides a composition comprising a compound Formula (I), or a pharmaceutically acceptable salt thereof, or any of the embodiments thereof, and at least one pharmaceutically acceptable carrier. These compositions can be prepared in a manner well known in the pharmaceutical art, and can be administered by a variety of routes, depending upon whether local or systemic treatment is indicated and upon the area to be treated. Administration may be topical (including transdermal, epidermal, ophthalmic and to mucous membranes including intranasal, vaginal and rectal delivery), pulmonary (e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal or intranasal), oral or parenteral. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal intramuscular or injection or infusion; or intracranial, e.g., intrathecal or intraventricular, administration. Parenteral administration can be in the form of a single bolus dose, or may be, e.g., by a continuous perfusion pump. Pharmaceutical compositions and formulations for topical administration may include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable.
This invention also includes pharmaceutical compositions which contain, as the active ingredient, the compound of the invention or a pharmaceutically acceptable salt thereof, in combination with one or more pharmaceutically acceptable carriers (excipients). In some embodiments, the composition is suitable for topical administration. In making the compositions of the invention, the active ingredient is typically mixed with an excipient, diluted by an excipient or enclosed within such a carrier in the form of, e.g., a capsule, sachet, paper, or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, e.g., up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions and sterile packaged powders.
In preparing a formulation, the active compound can be milled to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size can be adjusted by milling to provide a substantially uniform distribution in the formulation, e.g., about 40 mesh.
The compounds of the invention may be milled using known milling procedures such as wet milling to obtain a particle size appropriate for tablet formation and for other formulation types. Finely divided (nanoparticulate) preparations of the compounds of the invention can be prepared by processes known in the art see, e.g., WO 2002/000196.
Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions of the invention can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art.
In some embodiments, the pharmaceutical composition comprises silicified microcrystalline cellulose (SMCC) and at least one compound described herein, or a pharmaceutically acceptable salt thereof. In some embodiments, the silicified microcrystalline cellulose comprises about 98% microcrystalline cellulose and about 2% silicon dioxide w/w.
In some embodiments, the composition is a sustained release composition comprising at least one compound described herein, or a pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable carrier. In some embodiments, the composition comprises at least one compound described herein, or a pharmaceutically acceptable salt thereof, and at least one component selected from microcrystalline cellulose, lactose monohydrate, hydroxypropyl methylcellulose and polyethylene oxide. In some embodiments, the composition comprises at least one compound described herein, or a pharmaceutically acceptable salt thereof, and microcrystalline cellulose, lactose monohydrate and hydroxypropyl methylcellulose. In some embodiments, the composition comprises at least one compound described herein, or a pharmaceutically acceptable salt thereof, and microcrystalline cellulose, lactose monohydrate and polyethylene oxide. In some embodiments, the composition further comprises magnesium stearate or silicon dioxide. In some embodiments, the microcrystalline cellulose is Avicel PH102™. In some embodiments, the lactose monohydrate is Fast-flo 316™. In some embodiments, the hydroxypropyl methylcellulose is hydroxypropyl methylcellulose 2208 K4M (e.g., Methocel K4 M Premier™) and/or hydroxypropyl methylcellulose 2208 K100LV (e.g., Methocel KOOLV™). In some embodiments, the polyethylene oxide is polyethylene oxide WSR 1105 (e.g., Polyox WSR 1105™).
In some embodiments, a wet granulation process is used to produce the composition. In some embodiments, a dry granulation process is used to produce the composition.
The compositions can be formulated in a unit dosage form, each dosage containing from about 5 to about 1,000 mg (1 g), more usually about 100 mg to about 500 mg, of the active ingredient. In some embodiments, each dosage contains about 10 mg of the active ingredient. In some embodiments, each dosage contains about 50 mg of the active ingredient. In some embodiments, each dosage contains about 25 mg of the active ingredient. The term “unit dosage forms” refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.
The components used to formulate the pharmaceutical compositions are of high purity and are substantially free of potentially harmful contaminants (e.g., at least National Food grade, generally at least analytical grade, and more typically at least pharmaceutical grade). Particularly for human consumption, the composition is preferably manufactured or formulated under Good Manufacturing Practice standards as defined in the applicable regulations of the U.S. Food and Drug Administration. For example, suitable formulations may be sterile and/or substantially isotonic and/or in full compliance with all Good Manufacturing Practice regulations of the U.S. Food and Drug Administration.
The active compound may be effective over a wide dosage range and is generally administered in a therapeutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms and the like.
The therapeutic dosage of a compound of the present invention can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the invention in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the invention can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 μg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.
For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present invention. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid preformulation is then subdivided into unit dosage forms of the type described above containing from, e.g., about 0.1 to about 1000 mg of the active ingredient of the present invention.
The tablets or pills of the present invention can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.
The liquid forms in which the compounds and compositions of the present invention can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.
Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner.
Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, e.g., liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g., glycerinemonostearate, PEG-glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, e.g., glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2 or at least about 5 wt % of the compound of the invention. The topical formulations can be suitably packaged in tubes of, e.g., 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition.
The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient and the like.
The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers or stabilizers will result in the formation of pharmaceutical salts.
The therapeutic dosage of a compound of the present invention can vary according to, e.g., the particular use for which the treatment is made, the manner of administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the invention in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the invention can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 μg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems.
The compounds of the invention can further be useful in investigations of biological processes in normal and abnormal tissues. Thus, another aspect of the present invention relates to labeled compounds of the invention (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating TEAD transcription factor in tissue samples, including human, and for identifying TEAD transcription factor ligands by inhibition binding of a labeled compound. Accordingly, the present invention includes assays that contain such labeled compounds.
The present invention further includes isotopically-labeled compounds of the invention. An “isotopically” or “radio-labeled” compound is a compound of the invention where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present invention include but are not limited to 3H (also written as T for tritium), 11C, 13C, 14C, 13N, 15N, 15O, 17O, 18O, 18F, 35S, 36Cl, 82Br, 75Br, 76Br, 77Br, 123I, 124I, 125I and 131I. The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro labeling and competition assays, compounds that incorporate 3H, 14C, 82Br, 125I, 131I, 35S or will generally be most useful. For radio-imaging applications 11C, 18F, 125I, 123I, 124I, 131I, 75Br, 76Br or 77Br will generally be most useful.
It is to be understood that a “radio-labeled” or “labeled compound” is a compound that has incorporated at least one radionuclide. In some embodiments the radionuclide is selected from the group consisting of 3H, 14C, 125I, 35S and 82Br. In some embodiments, the compound incorporates 1, 2 or 3 deuterium atoms. Synthetic methods for incorporating radio-isotopes into organic compounds are known in the art.
Specifically, a labeled compound of the invention can be used in a screening assay to identify and/or evaluate compounds. For example, a newly synthesized or identified compound (i.e., test compound) which is labeled can be evaluated for its ability to bind a TEAD transcription factor by monitoring its concentration variation when contacting with the TEAD transcription factor, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to a TEAD transcription factor (i.e., standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to the TEAD transcription factor directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained.

A solution of compound-XIV (0.2 g, 0.74 mmol, 1 eq.) and Intermediate-I.1 (0.185 g, 0.81 mmol, 1.1 eq.) was cooled in ice. HATU (0.34 g, 0.89 mmol, 1.2 eq.) followed by DIPEA (0.39 mL, 2.22 mmol, 3 eq.) were added and allowed to stir at RT for 16 h. Reaction mass was added to ice water slowly under stirring. The obtained precipitate was filtered, washed with cold water twice followed by n-pentane twice and dried in vacuo to afford title compound as cream coloured solid (0.35 g, 98%).

Biological Assays
In Vitro Palmitoylation
Recombinant GST-TEAD2 or His6TEAD2 (500 ng) protein was pre-incubated with the compounds at indicated concentrations for 15 min. and then incubated with 1 μM of alkyne palmitoyl-5 CoA (Cayman Chemical) for 30 min or 50 mM MES, pH 6.4, followed by Click reaction with biotin-azide as previously described (Zheng, B. et al., J. Am. Chem. Soc., 2013, 135, 7082-7085). Click reaction was performed with 100 μM biotin-azide, 1 mM tris(2-carboxyethyl) phosphine hydrochloride (TCEP), 100 μM tris[(1-benzyl-1H-1,2,3-triazol-4-yl) methyl] amine (TBTA) and 1 mM CuSO4 for 1 h at RT.
The reactions were terminated by the addition of 12 μL of 6×SDS-sample loading buffer (50 mM Tris-HCl, pH 6.8, 6% SDS, 48% Glycerol, 0.03% Bromophenol Blue, 30 mM EDTA, 9% MeSH). Samples were analysed by SDS-PAGE and Western blot was performed by probing with streptavidin HRP and histidine HRP antibodies independently. Bands intensity obtained from streptavidin blot were quantified using BIORAD, Gel doc system and the percentage of inhibition of Tead2 auto palmitoylation is determined by comparing to the DMSO control treated samples.
These compounds were tested for activity in inhibiting TEAD2 palmitoylation in the assay described above. The data for the compounds is provided in below table as a percentage of inhibition of TEAD2 palmitoylation by the compound at a concentration of 10 PM.
Cell Proliferation
HuH7 cells (or other cells) are cultured in DMEM supplemented with 10% FBS. The cells are seeded in 96-wells with 5000 cells/well density. After cell attached to the wells, compounds in DMSO solution were added (1% DMSO concentration) to the cells with serial dilutions for the indicated final concentration. The cells were further incubated for 3 days. The cell viability is then determined using CellTiter Glo, MTT or crystal violet staining. The inhibition curve is plotted by using GraphPad.
qRT-PCR
YAP target gene expression was analyzed with a LightCycler 480 (Roche). Total RNA was isolated from cells using TRIzol (Life Technologies) and then used to produce cDNA with the Transcriptor First Strand cDNA Synthesis Kit (Roche). The resulting cDNA was then used in reactions with the LightCycler 480 SYBR Green I Master mix (Roche) with probes detecting CTGF or CYR61, and GAPDH.
CMP Assay
7-Diethylamino-3-(4′-Maleimidylphenyl)-4-Methylcoumarin (CPM), which reacts with thiol of CoA liberated in the enzymatic reaction, and gives fluorescent signal (excitation ˜350-380, emission-460-480). The assay detects the product (free CoA) which is produced from palmitoyl-CoA as a method to detect the enzymatic activity. Test compounds that inhibit TEAD activity are therefore able to block the CMP fluorescent signal.
TEAD2/4 protein (10 μL of a 50 ng/μL solution) and a solution the test compound (0.5 μL, variable concentration) were pre-incubated for 30 min at r.t. A mixture prepared from MES pH 6.4 buffer (6.5 μL of a 50 mM solution), EDTA (1 μL of a 20 mM solution), palmitoyl-CoA (1 μL of a 20 μM solution), and 7-diethylamino-3-(4′-maleimidylphenyl)-4-methylcoumarin (1 μL of a 10 μM solution) was added and the resulting mixture was mixed well using a pipette. The solution was then incubated at r.t. for 30-120 min. in the dark, and fluorescence was detected at 350 nm every 30 min. until the fluorescence signal is saturated. An IC50 for the ability of the compound to inhibit fluorescence is calculated from the results.
Results of the biological assays are shown in
