FIELD

The present invention is directed to allosteric chromenone inhibitors of phosphoinositide 3-kinase (PI3K) useful in the treatment of diseases, or disorders associated with PI3K modulation. The invention is directed toward compounds, and compositions which inhibit PI3K, methods of (or uses for) treating a disease, or disorder associated with PI3K (e.g., CLOVES syndrome (congenital lipomatous overgrowth, vascular malformations, epidermal naevi, scoliosis/skeletal and spinal syndrome), PIK3CA-related overgrowth syndrome (PROS), breast cancer, brain cancer, prostate cancer, endometrial cancer, gastric cancer, leukemia, lymphoma, sarcoma, colorectal cancer, lung cancer, ovarian cancer, skin cancer, or head and neck cancer), and using, or methods of using, PI3K inhibitors in combination with one or more additional cancer therapies.

BACKGROUND

The activity of cells can be regulated by external signals that stimulate, or inhibit intracellular events. The process by which stimulatory, or inhibitory signals are transmitted into, and within a cell to elicit an intracellular response is referred to as signal transduction. Over the past decades, cascades of signal transduction events have been elucidated, and found to play a central role in a variety of biological responses. Defects in various components of signal transduction pathways have been found to account for a vast number of diseases, including numerous forms of cancer, inflammatory disorders, metabolic disorders, vascular, and neuronal diseases (Gaestel et al. Current Medicinal Chemistry (2007) 14:2214-2234).

Kinases represent a class of important signaling molecules. Kinases can generally be classified into protein kinases, lipid kinases, and certain kinases exhibiting dual specificities. Protein kinases are enzymes that phosphorylate other proteins and/or themselves (i.e., autophosphorylation). Protein kinases can be generally classified into three major groups based upon their substrate utilization: tyrosine kinases which predominantly phosphorylate substrates on tyrosine residues (e.g., erb2, PDGF receptor, EGF receptor, VEGF receptor, src, abl), serine/threonine kinases which predominantly phosphorylate substrates on serine and/or threonine residues (e.g., mTorC1, mTorC2, ATM, ATR, DNA-PK, Akt), and dual-specificity kinases which phosphorylate substrates on tyrosine, serine and/or threonine residues.

Lipid kinases are enzymes that catalyze the phosphorylation of lipids within cells. These enzymes, and the resulting phosphorylated lipids, and lipid-derived biologically active organic molecules, play a role in many different physiological processes, including cell proliferation, migration, adhesion, and differentiation. A particular group of lipid kinases comprises membrane lipid kinases, i.e., kinases that catalyze the phosphorylation of lipids contained in, or associated with cell membranes. Examples of such enzymes include phosphoinositide(s) kinases (such as PI3-kinases, PI4-Kinases), diacylglycerol kinases, and sphingosine kinases.

The phosphoinositide 3-kinases (PI3Ks) signaling pathway is one of the most highly mutated systems in human cancers. PI3K signaling is involved in many other disease states including allergic contact dermatitis, rheumatoid arthritis, osteoarthritis, inflammatory bowel diseases, chronic obstructive pulmonary disorder, psoriasis, multiple sclerosis, asthma, disorders related to diabetic complications, and inflammatory complications of the cardiovascular system such as acute coronary syndrome.

PI3Ks are members of a unique, and conserved family of intracellular lipid kinases that phosphorylate the 3′-OH group on phosphatidylinositols, or phosphoinositides. The PI3K family comprises 15 kinases with distinct substrate specificities, expression patterns, and modes of regulation (Katso et al., Annu Rev Cell Dev Biol. 2001; 17:615-75). The class I PI3Ks (p110α, p110β, p110δ, and p110γ) are typically activated by tyrosine kinases, or G-protein coupled receptors to generate PIP3, which engages downstream effectors such as those in the pathways of Akt/PDK1, mTOR, the Tec family kinases, and the Rho family GTPases. The class II, and III PI3Ks play a key role in intracellular trafficking through the synthesis of PI(3)P, and PI(3,4)P₂.

The PI3K isoforms have been implicated, for example, in a variety of human cancers, and disorders. Mutations in the gene coding for PI3K isoforms, or mutations which lead to upregulation of a PI3K isoform are believed to occur in many human cancers. Mutations in the gene coding for a PI3K isoform are point mutations clustered within several hotspots in helical, and kinase domains. Because of the high rate of PI3K mutations, targeting of this pathway may provide valuable therapeutic opportunities.

Genetic alterations in genes in PI3K signaling are believed to be involved in a range of cancers such as endometrial cancer, breast cancer, esophageal squamous-cell cancer, cervical squamous-cell carcinoma, cervical adenocarcinoma, colorectal adenocarcinoma, bladder urothelial carcinoma, glioblastoma, ovarian cancer, non-small-cell lung cancer, esophagogastric cancer, nerve-sheath tumor, head and neck squamous-cell carcinoma, melanoma, esophagogastric adenocarcinoma, soft-tissue sarcoma, prostate cancer, fibrolamellar carcinoma, hepatocellular carcinoma, diffuse glioma, colorectal cancer, pancreatic cancer, cholangiocarcinoma, B-cell lymphoma, mesothelioma, adrenocortical carcinoma, renal non-clear-cell carcinoma, renal clear-cell carcinoma, germ-cell carcinoma, thymic tumor, pheochromocytoma, miscellaneous neuroepithelial tumor, thyroid cancer, leukemia, and encapsulated glioma (Goncalves M D, Hopkins B D, Cantley L C. Phosphatidylinositoi 3-Kinase, Growth Disorders, and Cancer. N Engl. Jr Med. 2018 Nov. 22; 379(21):2052-2062).

The alpha (α) isoform of PI3K has been implicated, for example, in a variety of human cancers. Angiogenesis has been shown to selectively require the a isoform of PI3K in the control of endothelial cell migration. (Graupera et al, Nature 2008; 453; 662-6). Mutations in the gene coding for PI3Kα, or mutations which lead to upregulation of PI3Kα are believed to occur in many human cancers such as lung, stomach, endometrial, ovarian, bladder, breast, colon, brain, prostate, and skin cancers. Mutations in the gene coding for PI3Kα are point mutations clustered within several hotspots in helical, and kinase domains, such as E542K, E545K, and H1047R.

Many of these mutations have been shown to be oncogenic gain-of-function mutations. Because of the high rate of PI3Kα mutations, targeting of this pathway may provide valuable therapeutic opportunities. While other PI3K isoforms such as PI3Kδ, or PI3Kγ are expressed primarily in hematopoietic cells, PI3Kα, along with PI3Kβ, is expressed constitutively.

Mutated PI3Kα has been implicated in brain metastases in HR+/HER2− metastatic breast cancers. Development of brain-penetrant PI3Kα inhibitors may provide improved therapeutic benefit over current PI3Kα inhibitors. (Fitzgerald et al., Association between PIK3CA mutation status and development of brain metastases in HR+/HER2− metastatic breast cancer. Ann Oncol 30:v110, 2019 (suppl 5)).

Due to the central role of PI3Kα in regulating organismal glucose homeostasis, PI3K inhibition in patients often gives rise to hyperglycemia and/or hyperinsulinemia (Busaidy N L, et al, Management of metabolic effects associated with anticancer agents targeting the PI3K-Akt-mTOR pathway. J Clin Oncol 2012; 30:2919-28). High levels of circulating insulin could potentially be mitogenic and/or antiapoptotic for cancer cells, and thus negate the antiproliferative effects of PI3K inhibitors (Blouin M-J, et al, Abstract 4615: The hyperinsulinemia caused by PI3K inhibitors attenuates their antineoplastic efficacy, but can be minimized by co-administration of metformin. Cancer Res 2013; 73:4615).

In the setting of cancer with mutated PI3Kα, one way to overcome the problem of compensatory production of insulin and/or glucose upon systemic PI3Kα inhibition would be to develop inhibitors with enhanced selectivity for mutant PI3Kα over wild-type PI3Kα. This would create an increased window for drug dosing to selectively inhibit the pathologic signaling of mutant PI3Kα in the cancer cells without affecting the wild-type PI3Kα in the host tissues that control systemic metabolism (Okkenhaug K, Graupera M, Vanhaesebroeck B. Targeting PI3K in Cancer: Impact on Tumor Cells, Their Protective Stroma, Angiogenesis, and Immunotherapy. Cancer Discov. 2016 October; 6(10):1090-1105), thus limiting toxicities, and permitting higher doses, and more complete inhibition of the drug target (Ariella B. Hanker, et al, Challenges for the clinical development of PI3K inhibitors: Strategies to improve their impact in solid tumors. Cancer Discov. 2019 April; 9(4): 482-491).

Currently PI3Kα inhibitors are nearly equipotent to wild-type, and mutant PI3Kα. Mutant selective inhibitors have been elusive due to the PI3Kα mutations location far from the active site. As such, inhibitors which target a second, peripheral binding pocket near a known mutation (e.g., H1047R) may provide a route to selective PI3Kα inhibition. Thus, targeting a mutated, peripheral binding pocket of PI3Kα, provides a valuable therapeutic target for drug development.

As such, kinases, for example lipid kinases such as PI3Ks, are prime targets for drug development. The present invention provides a new class of kinase inhibitors.

Examples of heterocyclyl rings include, but are not limited to, oxetanyl, azetidinyl, tetrahydrofuranyl, tetrahydropyranyl, pyrrolidinyl, oxazolinyl, oxazolidinyl, thiazolinyl, thiazolidinyl, pyranyl, thiopyranyl, tetrahydropyranyl, dioxalinyl, piperidinyl, morpholinyl, thiomorpholinyl, thiomorpholinyl S-oxide, thiomorpholinyl S-dioxide, piperazinyl, azepinyl, oxepinyl, diazepinyl, tropanyl, oxazolidinonyl, and homotropanyl.

The term “hydroxyalkyl” refers to an alkyl group, as defined herein, which is substituted with a hydroxy group.

The term “isomers” refers to compounds that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”. Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomers or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”.

The term “modulate”, “modulation”, or “modulating” refers to a biological activity of a compound, or substrate that inhibits and/or activates PI3K.

The term “patient”, or “subject” is a mammal, e.g., a human, mouse, rat, guinea pig, dog, cat, horse, cow, pig, or non-human primate, such as a monkey, chimpanzee, baboon, or rhesus. Preferably, the mammal is human.

The term “therapeutically effective amount” when used in connection with a compound refers to the amount or dose of the compound which upon single or multiple dose administration to the patient, provides the desired effect in the patient under diagnosis or treatment. An effective amount can be determined by one skilled in the art by the use of known techniques and by observing results obtained under analogous circumstances. In determining the effective amount for a patient, a number of factors are considered by the attending diagnostician, including, but not limited to: the species of patient; its size, age, and general health; the specific disease or disorder involved; the degree of or involvement or the severity of the disease or disorder; the response of the individual patient; the particular compound administered; the mode of administration; the bioavailability characteristics of the preparation administered; the dose regimen selected; the use of concomitant medication; and other relevant circumstances.

The term “treating” with regard to a subject, includes restraining, slowing, stopping, or reversing the progression or severity of an existing symptom or disorder.

A pharmaceutically acceptable salt of a compound of the present invention is, for example, an acid-addition salt of a compound of the invention, which is sufficiently basic, for example, an acid-addition salt with, for example, an inorganic or organic acid, for example hydrochloric, hydrobromic, sulfuric, phosphoric, trifluoroacetic, formic, citric, methane sulfonate or maleic acid. In addition, a pharmaceutically acceptable salt of a compound of the present invention which is sufficiently acidic is an alkali metal salt, for example a sodium or potassium salt, an alkaline earth metal salt, for example a calcium or magnesium salt, an ammonium salt or a salt with an organic base which affords a pharmaceutically acceptable cation, for example a salt with methylamine, dimethylamine, diethylamine, trimethylamine, piperidine, morpholine or tris-(2-hydroxyethyl)amine. Pharmaceutically acceptable salts, and common methodology for preparing them are well known in the art (see, e.g., P. Stahl, et al. Handbook of Pharmaceutical Salts: Properties, Selection, and Use, 2^ndRevised Edition (Wiley-VCH, 2011); S. M. Berge, et al., “Pharmaceutical Salts,” Journal of Pharmaceutical Sciences, Vol. 66, No. 1, January 1977).

Further representative “pharmaceutically acceptable salts” include, e.g., water-soluble, and water-insoluble salts, such as the acetate, amsonate (4,4-diaminostilbene-2,2-disulfonate), benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, butyrate, calcium, calcium edetate, camsylate, carbonate, chloride, citrate, clavulanate, dihydrochloride, edetate, edisylate, estolate, esylate, fumarate, gluceptate, gluconate, glutamate, glycollylarsanilate, hexafluorophosphate, hexylresorcinate, hydrabamine, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isothionate, lactate, lactobionate, laurate, magnesium, malate, maleate, mandelate, mesylate, methylbromide, methylnitrate, methylsulfate, mucate, napsylate, nitrate, N-methylglucamine ammonium salt, 3-hydroxy-2-naphthoate, oleate, oxalate, palmitate, pamoate, pantothenate, phosphate/diphosphate, picrate, polygalacturonate, propionate, p-toluenesulfonate, salicylate, stearate, subacetate, succinate, sulfate, sulfosalicylate, tannate, tartrate, teoclate, tosylate, triethiodide, and valerate salts.

The compounds of the present invention can be prepared in a number of ways well known to those skilled in the art of organic synthesis. By way of example, compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art. Preferred methods include but are not limited to those methods described below. Compounds of the present invention can be synthesized by following the steps outlined in General Schemes 1, 2, 3, and 4 which comprise different sequences of assembling intermediates or compounds. Starting materials are either commercially available or made by known procedures in the reported literature or as illustrated below.

Scheme 1 depicts the preparation of compounds of Formula (I), where R is —H, R₇is methyl, and R₈is —H. Acylation of substituted phenol (1) can provide ester (2). Ester (2) can undergo rearrangement under Lewis acid (e.g., AlCl₃) or Brønsted acid (e.g., triflic acid) conditions to provide hydroxy aryl ketone (3). Basic deprotonation of ketone (3) in the presence of carbon disulfide can provide the bicyclic chromene-2-thione (4).

Alkylation of thione (4) under basic conditions can afford thiolether (5). Phenyl bromide (5) can be acylated via palladium catalysis to produce acyl chromen-4-one (6). Exemplary palladium catalysis conditions may include phenyl bromide (5), about 5-10 mol % PdCl₂(Ph₃)₂and about 1.2 eq tributyl(1-ethoxyvinyl)stannane in about 30-35 equivalents dioxane at 95° C. for about 16 hours. Aryl ketone (6) can be reduced to hydroxy compound (7) with a reagent such as sodium borohydride. Use of a halogenating agent such as phosphorus tribromide can be used to convert hydroxy compound (7) to the halo compound (8).

Halo compound (8) can be used to alkylate an arylamine or heteroarylamine to give amine (9). Thiolether (9) can be converted to compounds of Formula (I) using transition metal catalysis to couple bicyclic boronic acids, boronic esters, or other coupling partners, followed by hydrolysis of an ester if present on R₁.

Scheme 2 depicts another preparation of compounds of Formula (I), where R is —H, R₇is methyl, and R₈is —H. Oxidation of thiolether (9) with an oxidant such as m-CPBA can give sulfoxide (10). Sulfoxide (10) can be converted to compounds of Formula (I) by substitution with various bicyclic heteroaryl amines followed by hydrolysis of an ester if present on R₁.

Scheme 3 depicts the preparation of compounds of Formula (II) where R is —H, R₇is methyl, and R₈is —H. Ketone (6) can be reduced to hydroxy compound (11) with a chiral catalyst such as the Noyori catalyst. The hydroxyl group in compound (11) can be converted into a leaving group with methanesulfonic anhydride or methanesulfonyl chloride to give mesylate (12). Mesylate (12) can be used to alkylate an arylamine or heteroarylamine to give amine (15). Thiolether (15) can be converted to compounds of Formula (II) using transition metal catalysis to couple bicyclic heteroaryl boronic acids, bicyclic heteroaryl boronate esters, or other coupling partners, followed by hydrolysis of the ester if present on R₁.

Scheme 3 also depicts the preparation of compounds of Formula (II) where R is —H, R₇is methyl, and R₈is —H. Ketone (6) can be reduced to hydroxy compound (13) with a chiral catalyst such as the Noyori catalyst. The hydroxyl group in compound (13) can be converted with chlorinating agents such as 2,4,6-trichloro-1,3,5-triazine to chloride (14). Chloride (14) can be used to alkylate an arylamine or heteroarylamine to give amine (15). Thiolether (15) can be converted to compounds of Formula (II) using transition metal catalysis to couple bicyclic heteroaryl boronic acids, bicyclic heteroaryl boronate esters, or other coupling partners, followed by hydrolysis of an ester if present on R₁.

Scheme 4 depicts an alternative preparation of compounds of Formula (II) where R is —H, R₇is methyl, and R₈is —H. Thiolether (6) can be converted to 2-substituted chromenone (16) using transition metal catalysis to couple bicyclic heteroaryl boronic acids, bicyclic heteroaryl boronate esters, or other coupling partners. Ketone (16) can be reduced to hydroxy compound (17) with a chiral catalyst such as the Noyori catalyst. The hydroxyl compound (17) can be converted into a leaving group with methanesulfonic anhydride or methanesulfonyl chloride to give mesylate (18). Mesylate (18) can be used to alkylate an arylamine or heteroarylamine to give compounds of Formula (II) after hydrolysis of the ester present on R₁.

Alternatively, ketone (16) can be reduced to hydroxy compound (19) with a chiral catalyst such as the Noyori catalyst. The hydroxyl group can be converted to chloride (20) with a chlorinating agent such as 2,4,6-trichloro-1,3,5-triazine. Chloride (20) can then be used to alkylate an arylamine or heteroarylamine to give compounds of Formula (II) after hydrolysis of an ester present if present on R₁.

Treated the reaction with 6-bromo-2-methyl-1,3-benzothiazole (172.16 mg, 0.75 mmol), bis(pinacoloto)diboron (383.32 mg, 1.51 mmol), copper(I) thiophene-2-carboxylate (215.88 mg, 1.13 mmol), cesium carbonate (491.82 mg, 1.51 mmol), RuPhos Pd G3 (31.56 mg, 0.04 mmol), and XPhos Pd G3 (31.94 mg, 0.04 mmol) to the reaction and stirred at 80° C. for another 16 h. The reaction was concentrated and diluted with 30 mL each of dichloromethane and water. The pH was adjusted to pH 3 with 2M aqueous HCl, the organic layer removed and the remaining aqueous layer extracted with dichloromethane (3×30 mL). The combined organic layers were dried over Na₂SO₄, filtered, and concentrated. The resulting residue was purified by silica gel chromatography eluted with 0% to 100% (EtOAc/dichloromethane=3:1) in petroleum ether and then 0% to 6% MeOH in dichoromethane to give the product (22.86 mg, 13%) as an off-white solid.

The tube was evacuated and refilled with argon twice, 1,4-dioxane added to the tube, and the tube evacuated and refilled with argon 2 more times. The tube was sealed and the reaction heated at 90° C. After 5 h, added 50% of the coupling reactants to the tube, resealed, and stirred overnight at 90° C. LCMS indicated a mixture of the ester and the acid. Concentrated the reaction and the resulting residue was treated with 2 mL of dichloromethane and 5 mL of trifluoroacetic acid and the reaction allowed to stir at rt overnight. Concentrated the reaction and purified the residue via reversed phase chromatography eluted with 10% to 100% 0.1 TFA in water in AcCN (0.1% TFA as an additive) to obtain the product (110 mg, 55%) as a light tan solid.

PI3K-Alpha Kinase (PIK3CA) Activity, Wild-Type and H1047R Mutant and Determining IC50 Values for Inhibitors

Recombinant, catalytically active human full length PIK3KA Wild-type and H1047R mutant were purchased as 1:1 complex of N-terminal 6×his tagged p110a (catalytic) and untagged p85a (regulatory subunit) from EMD Millipore Sigma (cat. no. 14-602M and 14-792M, respectively). PIP2diC8 (Avanti Polar Lipids Inc., cat. no. 850185) or Soy PI (Avanti Polar Lipids Inc., cat. No. 840044P) was used as lipid substrate. PIP2diC8 or PI lyophilized powder was dissolved in milliQ water to a concentration of 1 mM just before use. 10 mM stock compounds in DMSO were serially diluted 1:3 to generate a 10-point curve and plated using an acoustic liquid handler system (Echo 550 series instrument, Labcyte). A 10× intermediate compound plate (200 uM starting compound concentration and 10% DMSO) was prepared before starting the reaction. A typical reaction mixture (50 uL) comprised 40 mM HEPES buffer, pH 7.4, 25 mM MgCl₂, 0.01% v/v triton-X-100, 1% v/v DMSO, 20 mM NaCl, 1-5 nM WT or H1047R PI3K protein, 20 uM ATP, and 50 uM PIP2diC8 or Soy PI. 1% DMSO buffer alone without test compound was employed as MAX control (full activity in the absence of any inhibitor), and no enzyme control was used to determine the level of background Adenosine 5′-diphosphate (ADP) (MIN control). First, Wild-type (WT) and H1047R mutant protein in kinase buffer with all components except ATP were incubated with or without compound at 27° C. for 1 h. After the pre-incubation, the reaction was initiated by the addition of 20 uL of 50 uM ATP (20 uM final concentration). The reaction was allowed to proceed until about 10% conversion of ATP (2 uM ADP) at 27° C. After that time, 5 uL of reaction was mixed with 5 uL of ADP-Kinase Glo Reagent (ADP-Glo Kinase assay kit, Promega cat. no. V9102) supplemented with MgCl₂10 mM to stop the reaction and deplete the remaining ATP for 40 min at room temperature. Then, 10 uL of Kinase Detection Reagent (ADP-Glo Kinase assay kit, Promega cat. no. V9102) was added to simultaneously convert ADP to ATP and allow the newly synthesized ATP to be measured using a luciferase/luciferin reaction. After 30 min at room temperature the light generated was measured using a luminometer (EnVision plate reader, Perkin Elmer). Process data through Genedata-Screener tool. Relative IC₅₀values are determined using luminescence units by calculating percent inhibition with respect to on-plate “MIN” and “MAX” controls. Data was analyzed using a 4-parameter nonlinear logistic equation (four-parameter logistic concentration-response curve):

Y=bot+[(top−bot)/1+(x/IC50)slope]

where Y=% inhibition, X=concentration yielding y % inhibition, Bottom=minimum value of y attained by curve, Top=maximum value of y attained by curve and Slope=steepness of curve at IC50.

% Inh=[(median Max−x/median Max−median Min)]·100

IC50: concentration of compound that reduces a given response (ligand binding, enzyme response) by 50%. IC50 relative: concentration giving half the compound's maximum response.

For IC₅₀values shown in Table A, “A” means IC₅₀<0.5 μM; “B” means IC₅₀ranging between 0.5 μM and 1.0 μM; “C” means IC₅₀ranging between 1 μM and 5 μM; “D” means IC₅₀ranging between 5 μM and 10 μM; “E” means IC₅₀>10 μM.

PI3K-Alpha Kinase (PIK3CA) Activity In Vitro Cell Based Assay and Determining IC50 Values for Inhibitors

The MDA-MB-453 (ATCC-HTB-131) cell line was obtained from the American Type Culture Collection (Manassas, Va.). Cells were maintained in Dulbecco's Modified Eagle Media (DMEM, Gibco 11965-092) supplemented with 10% Fetal Bovine Serum, heat inactivated (FBS HI, Gibco 10082-147), 1× non-essential amino acids (NEAA, Gibco 11140-050), and 1 mM sodium pyruvate (Gibco 11360-070). Cultures were maintained in a humidified incubator at 37° C. under 5% CO₂/95% air.

For compound testing in 0% FBS, MDA-MB-453 cells were seeded at a density of 1.5×10⁴cells per well in white 384-well plates in 20 μl of Minimum Essential Media (MEM) assay media with 1×NEAA, 1 mM sodium pyruvate, and 1 μg/mL human insulin (Sigma I9278). Compounds dissolved in 10 mM stock solutions in DMSO were serially diluted 1:3 in DMSO to generate a 10-point dilution series and plated using an acoustic liquid handler system (Echo 550 Series Liquid Handler, Labcyte). A 5× intermediate compound dilution plate in MEM with 1×NEAA and 1 mM sodium pyruvate (150 μM starting compound concentration in 1.5% DMSO) was then prepared. Five μl of the intermediate serially diluted compounds were added to the cell plate to final concentrations ranging from 30 mM to 0.0015 mM in 0.3% DMSO. 0.3% DMSO alone was used to establish the maximum (MAX) signal and GDC-0032 at a final concentration of 1 μM was used as a reference compound for the minimum (MIN) signal. After 3 hours treatment, the medium was removed, and the cells lysed in 10 μL of 1× SureFire Lysis buffer with shaking for 10 minutes at room temperature. The Acceptor Mix (Reaction Buffer 1+Reaction Buffer 2+Activation Buffer+SureFire Ultra Acceptor Beads) was prepared by diluting Activation buffer 25-fold in combined Reaction Buffer 1 and Reaction Buffer 2. The Acceptor beads were diluted 50-fold in the combined Reaction Buffers. Five μL of Acceptor Mix was added to each well, the plate was sealed and covered with foil and incubated for 1 hour at room temperature. The Donor Mix (dilution buffer+SureFire Ultra Donor Beads) was prepared by diluting Donor Beads 50-fold in dilution buffer. Five μL of the Donor Mix was added to each well and the plate sealed and covered with foil and incubated for 1 hour at room temperature in the dark. The plates were read on a Neo2 plate reader instrument from Biotek using standard AlphaLisa settings. Compounds were tested in duplicate and the average % inhibition at each compound concentration was used to generate a single dose response curve. The data were processed using the Genedata-Screener tool. Relative IC50 values were determined using luminescence units by calculating percent inhibition with respect to the in-plate “MIN” (GDC-0032 reference control) and “MAX” (DMSO) controls. The data was analyzed using a 4-parameter nonlinear logistic equation (four-parameter logistic concentration-response curve):

Y=bottom+[(top−bottom)/1+(X/IC50)slope]

where Y=% inhibition, X=concentration of inhibitor, bottom=minimum value of y attained by curve-fit, top=maximum value of y attained by curve-fit and slope=steepness of curve at the IC₅₀.

% Inhibition=[(signal at X−median Min)/(median Max−median Min)]×100

IC₅₀: concentration of compound that reduces a given response (ligand binding, enzyme response) by 50%. Relative IC50: concentration giving half the compound's maximum response.

For IC₅₀values shown in Table B, “A” means IC₅₀<50 nM; “B” means IC₅₀ranging between 50 nM and 100 nM; “C” means IC₅₀ranging between 100 nM and 500 nM; “D” means IC₅₀>500 nM.
