[0068] 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”.

[0069] The term “modulate”, “modulation”, or “modulating” refers to a biological activity of a compound, or substrate that inhibits and/or activates PI3K.

[0070] 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.

[0071] 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.

[0072] The term “treating” with regard to a subject, includes restraining, slowing, stopping, or reversing the progression or severity of an existing symptom or disorder.

[0436] 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.sup.nd Revised Edition (Wiley-VCH, 2011); S. M. Berge, et al., “Pharmaceutical Salts,” Journal of Pharmaceutical Sciences, Vol. 66, No. 1, January 1977).

[0437] 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.

[0438] 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.

##STR00722##

[0439] Scheme 1 depicts the preparation of compounds of Formula (II), where R is H and R.sub.7 is methyl. Acylation of substituted phenol (1) may provide ester (2). Ester (2) may undergo rearrangement under Lewis acid (e.g., AlCl.sub.3) or Brønsted acid (e.g., triflic acid) conditions to the hydroxy aryl ketone (3). Acidic condensation of an aryl aldehyde with hydroxy aryl ketone (3) may provide keto-alkene (4) which may cyclize to the 2-substituted chromen-4-one (5).

Condensation of ketone (6) with tert-butanesulfinamide using a Lewis acidic dehydrating agent such as a titanium(IV) alkoxide may afford ketimine (7). Asymmetric reduction of sulfinimine (7) may be affected with a borohydride reagent in the presence of a transition metal catalyst such as cerium (III) chloride to yield chirally enriched sulfinamide (8). Removal of the sulfinyl group under acidic conditions may be used to transform sulfinamide (8) to benzylamine (9) which can be alkylated with an aryl or heteroaryl halide under Finkelstein or Ullmann-type conditions to give compounds of Formula (II) after hydrolysis of ester present on R.sub.1.

[0640] PI3K-Alpha Kinase (PIK3CA) Activity, Wild-Type and H1047R Mutant and Determining IC50 Values for Inhibitors

[0641] Recombinant, catalytically active human full length PIK3KA Wild-type and H1047R mutant were purchased as 1:1 complex of N-terminal 6× his tagged p110α (catalytic) and untagged p85α (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 MgCl.sub.2, 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 MgCl.sub.2 10 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 IC.sub.50 values 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)].Math.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.

[0642] For IC.sub.50 values shown in Table A, “A” means IC.sub.50<0.5 μM; “B” means IC.sub.50 ranging between 0.5 μM and 1.0 μM; “C” means IC.sub.50 ranging between 1 μM and 5 μM; “D” means IC.sub.50 ranging between 5 μM and 10 μM; “E” means IC.sub.50>10 μM.

[0643] PI3K-Alpha Kinase (PIK3CA) Activity In Vitro Cell Based Assay and Determining IC50 Values for Inhibitors

[0644] 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% CO.sub.2/95% air.

For compound testing in 0% FBS, MDA-MB-453 cells were seeded at a density of 1.5×10.sup.4 cells 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 IC.sub.50 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 IC.sub.50.

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

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

[0645] For IC.sub.50 values shown in Table B, “A” means IC.sub.50<50 nM; “B” means IC.sub.50 ranging between 50 nM and 100 nM; “C” means IC.sub.50 ranging between 100 nM and 500 nM; “D” means IC.sub.50>500 nM.
