## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims priority to and the benefit under 35 U.S.C. 119(e) of U.S. Provisional Patent Application Ser. No. 62/016,194, filed Jun. 24, 2014, the disclosure of which is hereby incorporated by reference in its entirety.


FIELD
The present disclosure relates generally to inhibitors of phosphatidylinositol 3-kinase (PI3K) activity and, more specifically, to novel compounds that are selective inhibitors of PI3K isoforms.
BACKGROUND
Cell signaling via 3′-phosphorylated phosphoinositides has been implicated in a variety of cellular processes, e.g., malignant transformation, growth factor signaling, inflammation, and immunity. See generally Rameh et al., J. Biol. Chem., 274:8347-8350 (1999). The enzyme responsible for generating these phosphorylated signaling products is phosphatidylinositol 3-kinase (PI 3-kinase; PI3K). PI3K originally was identified as an activity associated with viral oncoproteins and growth factor receptor tyrosine kinases that phosphorylate phosphatidylinositol (PI) and its phosphorylated derivatives at the 3′-hydroxyl of the inositol ring. See Panayotou et al., Trends Cell Biol 2:358-60 (1992).
Presently, three classes of the PI 3-kinase (PI3K) enzymes are distinguished, based on their substrate specificities. Class 1 PI3Ks can phosphorylate phosphatidylinositol (PI), phosphatidylinositol-4-phosphate, and phosphatidylinositol-4,5-biphosphate (PIP2) to produce phosphatidylinositol-3-phosphate (PIP), phosphatidylinositol-3,4-biphosphate, and phosphatidylinositol-3,4,5-triphosphate, respectively. Class II PI3Ks phosphorylate PI and phosphatidylinositol-4-phosphate, whereas Class III PI3Ks can only phosphorylate PI.
The initial purification and molecular cloning of PI 3-kinase revealed that it was a heterodimer consisting of p85 and p110 summits. See Otsu et al., Cell, 65:91-104 (1991); Hiles et al., Cell, 70:419-29 (1992). Since then, four distinct Class I PI3Ks have been identified, designated PI3K α, β, δ, and γ, each consisting of a distinct 110 kDa catalytic subunit and a regulatory subunit. More specifically, three of the catalytic sub-units, i.e., p110α, p110β, and p110δ, each interact with the same regulatory subunit, i.e., p85, whereas p110γ interacts with a distinct p101 regulatory subunit. As described below, the patterns of expression of each of these PI3Ks in human cells and tissues also are distinct.
Identification of the p110δ isoform of PI 3-kinase is described in Chantry et al., J. Biol. Chem., 272:19236-41 (1997). It was observed that the human p110δ isoform is expressed in a tissue-restricted fashion. It is expressed at high levels in lymphocytes and lymphoid tissues, suggesting that the protein might play a role in PI 3-kinase-mediated signaling in the immune system. Details concerning the p110δ isoform also can be found in U.S. Pat. Nos. 5,858,753; 5,822,910; and 5,985,589, each of which is incorporated herein by reference. See also Vanhaesebroeck et al., Proc. Natl. Acad. Sci. USA, 94:4330-5 (1997); and WO 97/46688.
A need remains, however, for additional therapeutic agents useful to treat proliferative disorders or diseases that are mediated by PI3K. The present invention provides novel compounds that are inhibitors of PI3K isoforms.

The terms “optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. Also, the term “optionally substituted” refers to any one or more hydrogen atoms on the designated atom or group may or may not be replaced by a moiety other than hydrogen.
The term “substituted” means that any one or more hydrogen atoms on the designated atom or group is replaced with one or more substituents other than hydrogen, provided that the designated atom's normal valence is not exceeded.

Polymers or similar indefinite structures arrived at by defining substituents with further substituents appended ad infinitum (e.g., a substituted aryl having a substituted alkyl which is itself substituted with a substituted aryl group, which is further substituted by a substituted heteroalkyl group, etc.) are not intended for inclusion herein. Unless otherwise noted, the maximum number of serial substitutions in compounds described herein is three. For example, serial substitutions of substituted aryl groups with two other substituted aryl groups are limited to ((substituted aryl)substituted aryl) substituted aryl. Similarly, the above definitions are not intended to include impermissible substitution patterns (e.g., methyl substituted with 5 fluorines or heteroaryl groups having two adjacent oxygen ring atoms). Such impermissible substitution patterns are well known to the skilled artisan. When used to modify a chemical group, the term “substituted” may describe other chemical groups defined herein. For example, the term “substituted aryl” includes, but is not limited to, “alkylaryl.” Unless specified otherwise, where a group is described as optionally substituted, any substituents of the group are themselves unsubstituted. One or more substituents may include, for example, 1, 2, 3, 4, 5, or 6 substitutents, 1, 2, 3, 4, or 5 substitutents, 1, 2, 3, or 4 substitutents, 1, 2, or 3 substituents, 1 or 2 substituents, or 1 substituent.

In any one of the foregoing embodiments, the compound described herein or a pharmaceutically acceptable salt thereof is the (S)-enantiomer. It is understood that each compound having a chiral center has enantiomers that correspond with the “a” and “b” example provided above.
A composition containing a mixture of enantiomers of the compound described herein or a pharmaceutically acceptable salt thereof, is also provided herein. In some embodiments, the composition contains the (S)-enantiomer of the compound and is substantially free of its corresponding (R)-enantiomer. In certain embodiments, a composition substantially free of the (R)-enantiomer has less than or about 40%, 35%, 30%, 25%, 20%, 15%, 10%, 5%, 1%, 0.05%, or 0.01% of the (R)-enantiomer.

A composition containing a mixture of atropisomers of the compound described herein or a pharmaceutically acceptable salt thereof, is also provided herein. “Atropisomers” refers to conformational stereoisomers which occur when rotation about a single bond in the molecule is prevented, or greatly slowed, as a result of steric interactions with other parts of the molecule and the substituents at both ends of the single bond are asymmetrical, i.e., they do not require a stereocenter. Where the rotational barrier about the single bond is high enough, and interconversion between conformations is slow enough, separation and isolation of the isomeric species may be permitted. Atropisomers are enantiomers without a single asymmetric atom. As an example, Compound 17 can be resolved into its individual atropisomers as depicted below.

For example, certain compounds may have selectivity to at least one PI3K isoform, including PI3Kδ, and have hepatocyte stability based on a half-life of greater than 3 hours. As used herein, the term “potency,” “potent,” or variants thereof refer to a compound exhibiting an IC50 value that is less than 100 nM. When comparing two compounds, the compound that exhibits a lower IC50 value is referred to as a more potent inhibitor.
“Treatment” or “treating” is an approach for obtaining beneficial or desired results including clinical results. Beneficial or desired clinical results may include one or more of the following: a) Inhibiting the disease or condition (e.g., decreasing one or more symptoms resulting from the disease or condition, and/or diminishing the extent of the disease or condition); b) slowing or arresting the development of one or more clinical symptoms associated with the disease or condition (e.g., stabilizing the disease or condition, preventing or delaying the worsening or progression of the disease or condition, and/or preventing or delaying the spread (e.g., metastasis) of the disease or condition); and/or c) relieving the disease, that is, causing the regression of clinical symptoms (e.g., ameliorating the disease state, providing partial or total remission of the disease or condition, enhancing effect of another medication, delaying the progression of the disease, increasing the quality of life, and/or prolonging survival.
“Prevention” or “preventing” means any treatment of a disease or condition that causes the clinical symptoms of the disease or condition not to develop. Compounds may, in some embodiments, be administered to a subject (including a human) who is at risk or has a family history of the disease or condition.
“Subject” refers to an animal, such as a mammal (including a human), that has been or will be the object of treatment, observation or experiment. The methods described herein may be useful in human therapy and/or veterinary applications. In some embodiments, the subject is a mammal. In one embodiment, the subject is a human. “Human in need thereof” refers to a human who may have or is suspect to have diseases, or disorders, or conditions that would benefit from certain treatment; for example, being treated with the PI3K inhibitor of the compounds according to the present application. In certain embodiments, the subject may be a human who (i) has not received any treatment including chemotherapy treatment, (ii) is substantially refractory to at least one chemotherapy treatment, (iii) is in relapse after treatment with chemotherapy, or both (I) and (ii). In some of embodiments, the subject is refractory to at least one, at least two, at least three, or at least four chemotherapy treatments (including standard or experimental chemotherapies).
The term “therapeutically effective amount” or “effective amount” of a compound described herein or pharmaceutically acceptable salts, isomer, or a mixture thereof means an amount sufficient to effect treatment when administered to a subject, to provide a therapeutic benefit such as amelioration of symptoms or slowing of disease progression. For example, a therapeutically effective amount may be an amount sufficient to decrease a symptom of a disease or condition responsive to inhibition of PI3Kδ activity. The therapeutically effective amount may vary depending on the subject and disease or condition being treated, the weight and age of the subject, the severity of the disease or condition, and the manner of administering, which can readily be determined by one or ordinary skill in the art.
The term “inhibition” indicates a decrease in the baseline activity of a biological activity or process, “Inhibition of activity of PI3K isoforms” or variants thereof refer to a decrease in activity in any PI3K isoform (e.g., alpha, beta, gamma, or delta) as a direct or indirect response to the presence of a compound of the present application relative to the activity of PI3K isoform in the absence of the compound of the present application. “Inhibition of PI3Kδ activity” or variants thereof refer to a decrease in PI3Kδ activity as a direct or indirect response to the presence of a compound described herein relative to the activity of PI3Kδ in the absence of the compound described herein. In some embodiments, the inhibition of PI3Kδ activity may be compared in the same subject prior to treatment, or other subjects not receiving the treatment.
Without wishing to be bound to any theory, the decrease in PI3Kδ activity may be due to the direct interaction of the compound with PI3Kδ, or due to the interaction of the compounds described herein with one or more other factors that in turn affect PI3Kδ activity. For example, the presence of the compounds of any of the foregoing formulae may decrease PI3Kδ activity by directly binding to the PI3Kδ, by causing (directly or indirectly) another factor to decrease PI3Kδ activity, or by (directly or indirectly) decreasing the amount of PI3Kδ present in the cell or organism.
The terms “PI3K isoform selective inhibitor” generally refers to a compound that inhibits the activity of one or more PI3K isoforms more effectively than the other remaining PI3K isoforms. By way of example, the term “PI3Kδ selective inhibitor” generally refers to a compound that inhibits the activity of the PI3Kδ isoform more effectively than other isoforms of the PI3K family (e.g., PI3K α, β, or γ). The term “PI3Kα selective inhibitor” generally refers to a compound that inhibits the activity of the PI3Kα isoform more effectively than other isoforms of the PI3K family (e.g., PI3K β, δ, or γ). The term “PI3Kβ selective inhibitor” generally refers to a compound that inhibits the activity of the PI3Kβ isoform more effectively than other isoforms of the PI3K family (e.g., PI3K α, δ, or γ). The term “dual PI3Kα/β selective inhibitor generally refers to a compound that inhibits the activity of the PI3Kα and PI3Kβ isoforms more effectively than other isoforms of the PI3K family (e.g., PI3K δ or γ).
The relative efficacies of compounds as inhibitors of an enzyme activity (or other biological activity) can be established by determining the concentrations at which each compound inhibits the activity to a predefined extent and then comparing the results. In one embodiment, the efficacy of a compound as an inhibitor of one or more PI3K isoforms can be measured by the concentration that inhibits 50% of the activity in a biochemical assay, i.e., the 50% inhibitory concentration or “IC50”. IC50 determinations can be accomplished using conventional techniques known in the art, including the techniques describes in the Examples below. In general, an IC50 can be determined by measuring the activity of a given enzyme in the presence of a range of concentrations of the compound under study. The experimentally obtained values of enzyme activity may then be plotted against the compound concentrations used. The concentration of the inhibitor that shows 50% enzyme activity (as compared to the activity in the absence of any inhibitor) is taken as the IC50 value. Analogously, other inhibitory concentrations can be defined through appropriate determinations of activity. For example, in some settings it may be desirable to establish a 90% inhibitory concentration, i.e., IC90.
In one embodiment, a PI3Kδ selective inhibitor is a compound that exhibits a 50% inhibitory concentration (IC50) with respect to PI3Kδ that is at least 10-fold, in another aspect at least 20-fold, and in another aspect at least 30-fold, lower than the IC50 value with respect to any or all of the other Class I PI3K family members. In another embodiment, a PI3Kδ selective inhibitor is a compound that exhibits an IC50 with respect to PI3Kδ that is at least 50-fold, in another aspect at least 100-fold, in an additional aspect at least 200-fold, and in yet another aspect at least 500-fold, lower than the IC50 with respect to any or all of the other PI3K Class I family members. A PI3Kδ selective inhibitor is typically administered in an amount such that it selectively inhibits PI3Kδ activity, as described above.
In one embodiment, a PI3Kα selective inhibitor is a compound that exhibits a 50% inhibitory concentration (IC50) with respect to PI3Kβ that is at least 10-fold, in another aspect at least 20-fold, and in another aspect at least 30-fold, lower than the IC50 value with respect to any or all of the other Class I PI3K family members. In another embodiment, a PI3Kα selective inhibitor is a compound that exhibits an IC50 with respect to PI3Kα that is at least 50-fold, in another aspect at least 100-fold, in an additional aspect at least 200-fold, and in yet another aspect at least 500-fold, lower than the IC50 with respect to any or all of the other PI3K. Class I family members. A PI3Kα selective inhibitor is typically administered in an amount such that it selectively inhibits PI3Kα activity, as described above
In one embodiment, a PI3Kβ selective inhibitor is a compound that exhibits a 50% inhibitory concentration (IC50) with respect to PI3Kβ that is at least 10-fold, in another aspect at least 20-fold, and in another aspect at least 30-fold, lower than the IC50 value with respect to any or all of the other Class I PI3K family members. In another embodiment, a PI3Kβ selective inhibitor is a compound that exhibits an IC50 with respect to PI3Kβ that is at least 50-fold, in another aspect at least 100-fold, in an additional aspect at least 200-fold, and in yet another aspect at least 500-fold, lower than the IC50 with respect to any or all of the other PI3K Class I family members. A PI3Kβ selective inhibitor is typically administered in an amount such that it selectively inhibits PI3Kβ activity, as described above.
The methods described herein may be applied to cell populations in vivo or ex vivo. “In vivo” means within a living individual, as within an animal or human. In this context, the methods described herein may be used therapeutically in an individual. “Ex vivo” means outside of a living individual. Examples of ex vivo cell populations include in vitro cell cultures and biological samples including fluid or tissue samples obtained from individuals. Such samples may be obtained by methods well known in the art. Exemplary biological fluid samples include blood, cerebrospinal fluid, urine, and saliva. Exemplary tissue samples include tumors and biopsies thereof. In this context, the invention may be used for a variety of purposes, including therapeutic and experimental purposes. For example, the invention may be used ex vivo to determine the optimal schedule and/or dosing of administration of a PI3Kδ selective inhibitor for a given indication, cell type, individual, and other parameters. Information gleaned from such use may be used for experimental purposes or in the clinic to set protocols for in vivo treatment. Other ex vivo uses for which the invention may be suited are described below or will become apparent to those skilled in the art. The selected compounds may be further characterized to examine the safety or tolerance dosage in human or non-human subjects. Such properties may be examined using commonly known methods to those skilled in the art.
Compared to other PI3K isoforms, PI3Kδ is generally expressed in hematopoietic cells. Consequently, the direct effects of selective inhibitors of PI3Kδ can be observed in hematopoietic cells. Hematopoietic cells typically differentiate into either lymphoid progenitor cells or myeloid progenitor cells, both of which ultimately differentiate into various mature cell types including leukocytes. Aberrant proliferation of hematopoietic cells of one type often interferes with the production or survival of other hematopoietic cell types, which can result in compromised immunity, anemia, and/or thrombocytopenia. The methods described herein may treat aberrant proliferation of hematopoietic cells by inhibiting aberrant proliferation of hematopoietic cells. As a result, these methods may also ameliorate the symptoms and secondary conditions that result from a primary effect such as excessive system or localized levels of leukocytes or lymphocytes.
In some embodiments, the compounds described herein may be used to treat subjects having various disease states, disorders, and conditions (also collectively referred to as “indications”) involving aberrant proliferation of hematopoietic cells (including excessive production of lymphoid progenitor cell-derived cells and/or myeloid progenitor cell-derived cells). Such indications may include, for example, leukemias, lymphomas, myeloproliferative disorders, myelodysplastic syndromes, and plasma cell neoplasms. In certain embodiments, the compounds described herein may be used to treat hematologic malignancies, inflammation, autoimmune disorders, allergic conditions, cardiovascular disease, and autoimmune diseases. In certain embodiments, allergic conditions may include all forms of hypersensitivity.
In other embodiments, the compounds described herein may be used to treat cancers that are mediated by, dependent on or associated with PI3K activity, such as PI3Kδ activity. In certain embodiments, the disease is a hematologic malignancy. In certain embodiments, the disease is lymphoma, multiple myeloma, or leukemia. In particular embodiments, the hematologic malignancy is leukemia or lymphoma. In specific embodiments, the disease is acute lymphocytic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), myelodysplasia syndrome (MDS), myeloproliferative disease (MPD), chronic myeloid leukemia (CML), juvenile myelomonocytic leukemia (JMML), multiple myeloma (MM), Hodgkin lymphoma, indolent non-Hodgkin's lymphoma (iNHL), refractory iNHL, non-Hodgkin's lymphoma (NHL), mantle cell lymphoma (MCL), follicular lymphoma, Waldestrom's macroglobulinemia (WM), minimal residual disease (MRD), T-cell lymphoma, B-cell lymphoma, diffuse large B-cell lymphoma (DLBCL), T-cell acute lymphoblastic leukemia (T-ALL), B-cell acute lymphoblastic leukemia (B-ALL), lymphoplamacytic lymphoma, marginal zone lymphoma, or Burkitt lymphoma.

Pharmaceutical Compositions and Modes of Administration
Compounds provided herein are usually administered in the form of pharmaceutical compositions. Thus, provides herein are also pharmaceutical compositions that contain one or more of the compounds described herein or pharmaceutically acceptable salts, isomer, or a mixture thereof and one or more pharmaceutically acceptable vehicles selected from carriers, adjuvants and excipients. Suitable pharmaceutically acceptable vehicles may include, for example, inert solid diluents and fillers, diluents, including sterile aqueous solution and various organic solvents, permeation enhancers, solubilizers and adjuvants. Such compositions are prepared in a manner well known in the pharmaceutical art. See, e.g., Remington's Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, Pa., 17th Ed. (1985); and Modern Pharmaceutics, Marcel Dekker, Inc. 3rd Ed. (G. S. Banker & C. T. Rhodes, Eds.).
The pharmaceutical compositions may be administered in either single or multiple doses. The pharmaceutical composition may be administered by various methods including, for example, rectal, buccal, intranasal and transdermal routes. In certain embodiments, the pharmaceutical composition may be administered by intra-arterial injection, intravenously, intraperitoneally, parenterally, intramuscularly, subcutaneously, orally, topically, or as an inhalant.
One mode for administration is parenteral, for example, by injection. The forms in which the pharmaceutical compositions described herein may be incorporated for administration by injection include, for example, aqueous or oil suspensions, or emulsions, with sesame oil, corn oil, cottonseed oil, or peanut oil, as well as elixirs, mannitol, dextrose, or a sterile aqueous solution, and similar pharmaceutical vehicles.
Oral administration may be another route for administration of the compounds described herein. Administration may be via, for example, capsule or enteric coated tablets. In making the pharmaceutical compositions that include at least one compound described herein or pharmaceutically acceptable salts, isomer, or a mixture thereof, the active ingredient is usually diluted by an excipient and/or enclosed within such a carrier that can be in the form of a capsule, sachet, paper or other container. When the excipient serves as a diluent, it can be in the form of 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, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, sterile injectable solutions, and sterile packaged powders.
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, sterile 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 that include at least one compound described herein or pharmaceutically acceptable salts, isomer, or a mixture thereof can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the subject by employing procedures known in the art. Controlled release drug delivery systems for oral administration include osmotic pump systems and dissolutional systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled release systems are given in U.S. Pat. Nos. 3,845,770; 4,326,525; 4,902,514; and 5,616,345. Another formulation for use in the methods of the present invention employs transdermal delivery devices (“patches”). Such transdermal patches may be used to provide continuous or discontinuous infusion of the compounds described herein in controlled amounts. The construction and use of transdermal patches for the delivery of pharmaceutical agents is well known in the art. See, e.g., U.S. Pat. Nos. 5,023,252, 4,992,445 and 5,001,139. Such patches may be constructed for continuous, pulsatile, or on demand delivery of pharmaceutical agents.
For preparing solid compositions such as tablets, the principal active ingredient may be mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound described herein or pharmaceutically acceptable salts, isomer, or a mixture thereof. When referring to these preformulation compositions as homogeneous, the active ingredient may be dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.
The tablets or pills of the compounds described herein may be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action, or to protect from the acid conditions of the stomach. For example, the tablet or pill can include 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 that 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.
Compositions for inhalation or insufflation may 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. In other embodiments, compositions in pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be inhaled directly from the nebulizing device or the nebulizing device may be attached to a facemask tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions may be administered, preferably orally or nasally, from devices that deliver the formulation in an appropriate manner.

Compounds of Formula I
One method of preparing compounds of formula (I) is shown in Reaction Scheme I.




Step 1—Preparation of a Compound of Formula (1)
The compound of formula (1) can be made by combining compounds (A), (B) and (C) in the presence of a dehydrating agent. Compounds (A), (B) and (C) are commercially available or can be made by methods known in the art. With respect to compound (A), R1 is as defined herein. With respect to compound (B), R3 and R5 are as defined herein. With respect to compound (C), R2 is as defined herein. Compound (A) can be mixed with Compound (B) in the presence of a coupling agent such as diphenyl phosphite in a solvent such as pyridine. After stirring at a temperature between ambient and 100° C. for between 1 and 5 hours, compound (C) is added. After further stirring at a temperature between ambient and 100° C. for between 5 and 24 hours, the reaction mixture is allowed to cool to room temperature. To extract the compound of formula (1), an organic solvent such as ethyl acetate (EtOAc) may be added, followed by washing with, mild acid, water, and brine. The organic phase can be concentrated to obtain the compound of formula (1). Additional compounds may be prepared by alkylation of compounds of formula (1) in which R1 is OH. For example a compound of formula (1), R1═OH, is mixed with a reagent containing a leaving group, such as a halide or mesylate, in the presence of a base, such as Cs2CO3 or K2CO3, in a solvent such as DMF or DMSO. After stirring at a temperature between ambient and 110° C. for between 5 and 24 hours, the reaction mixture is allowed to cool to room temperature and worked up under standard conditions. Additional compounds may be prepared by coupling reactions with compounds of formula (1) in which R1 is halo, such as iodo, bromo, or chloro. For example a compound of formula (1), R1═Br, may be mixed with a double bond containing compound, such as acrylamide, allyl alcohol, allylcyclohexane, or acrolein, in the presence of a base, such as Hunig's base, Cs2CO3 or K2CO3, and metal catalyst such as chloro(2-dicyclohexylphosphino-2′,4′,6′-triisopropyl-1,1′-biphenyl)[2-(2′-amino-1,1′-biphenyl)]palladium(II) in a solvent such as DMF. After stirring at a temperature between ambient and 110° C. for between 5 and 24 hours, the reaction mixture is allowed to cool to room temperature and worked up under standard conditions. If R1 contains a double bond, it can be reduced under standard conditions such as hydrogenation in the presence of a catalyst, such as Pd/C or Pt in a solvent such as EtOAc, EtOH, or MeOH under ambient or elevated pressure. If R1 contains an aldehyde, it can be converted to an amine under standard conditions such as reaction with a primary or secondary amine in the presence of sodium cyanoborohydride or sodium triacetoxyborohydride, in a solvent such as DCM, EtOAc, EtOH, or MeOH under ambient or elevated temperature. Compounds where R1 is SO2R may be prepared by reaction of a compound (1) where R1 is halo, such as Br, with sodium alkyl or aryl sulfinate in the presence of a base, such as Cs2CO3 or K2CO3, and a catalyst such as CuI, in a solvent such as DMSO, and heated at a temperature between ambient and 120° C. Further, compounds where R1 is SO2R may be prepared by first reacting a compound (1) where R1 is halo, such as Br, with a thiol in the presence of a base such as Hunig's base, a catalyst such as Pd(dba)2, a ligand such as Xantphos, and (S)-proline in a solvent such as dioxane, and heated at a temperature between ambient and 140° C. The resulting thiol can be oxidized by treatment with an oxidizing agent, such as oxone in an aqueous solvent such as a mixture of THF and water. Additionally for compounds that have a latent amine which is desired to be acylated, the amine may be reacted with an acid in the presence of base, such as Hunig's base or triethylamine and a coupling agent such as HATU or HOBT to give the amide. The compound of formula (1) may be purified by any suitable methods known in the art, such as chromatography on silica gel. Alternatively, the compound of formula (1) may be used in the next step without purification.
Step 2—Preparation of a Compound of Formula (2)
The compound of formula (2) can be made by removing the protecting group(s) from the compound of formula (1). The compound of formula (1) is dissolved in a suitable solvent and treated with a suitable acid. Suitable solvents may include, for example, dichloromethane,-dioxane, or other suitable solvents. Suitable acids may include, for example, trifluoroacetic acid, hydrochloric acid, or boron tribromide (BBr3). The reaction can be carried out at temperatures between −78° C. to ambient temperature. On reaction completion, solvent is removed to obtain the compound of formula (2). In the case of a reaction using BBr3 the reaction may first be treated with MeOH before an aqueous work-up to obtain a compound of formula (2).
Step 3—Preparation of a Compound of Formula (3)
The compound of formula (3) can be made by treating 5-substituted-2,4,6-trihalopyrimidine with ammonium hydroxide in a suitable solvent such as dioxane, where the halo is either chloro or fluoro. The reaction is carried out at an elevated temperature between 30 and 80° C. for a suitable time, typically between 2 and 8 hours or when the reaction is complete. Upon completion, water is added to the cooled solution, and the precipitate is collected by filtration. The nitrile can be converted to the carboxamide under standard conditions.
Step 4—Preparation of a Compound of Formula (I)
The compound of formula (I) can generally be prepared by coupling compound of formula (2) and compound of formula (3) in the presence of a suitable base in a suitable solvent. An example of a suitable base is diisopropylethylamine. An example of a suitable solvent is N-methylpyrrolidone (NMP), DMF, DMSO, isopropanol, or ethanol. The reaction is typically performed at a temperature between 30° C. to 150° C. for about 30 minutes to 120 hours. Alternatively the reaction can be performed in a microwave at a temperature between 100° C. to 150° C. for about 30 minutes to 24 hours. Water can be added to quench the reaction upon completion, and the precipitate may be filtered and then dissolved in an organic solvent such as dichloromethane (DCM). The product can be isolated by methods known in the art, for example by removal of solvent under reduced pressure. The product can be purified using any suitable methods known in the art, for example, chromatography of the residue on a silica column.
It should be understood that the compounds of formula (I) can be prepared according to the methods provided in Reaction Scheme 1, starting from materials known to one of skill in the art.

Biological Examples
Activity testing was conducted in the Examples below using methods described herein and those well known in the art. Enzymatic activity of PI3K isoforms were measured to compare the PI3K isoform activity and selectivity of the compounds tested, including selectivity to PI3Kδ. A cellular assay measuring basophil activation was used to assess the potency of the compounds tested.
Enzymatic activity of the class I PI3K isoforms in the presence of certain compounds of the present application and compounds X and Y was measured using a time-resolved fluorescence resonance energy transfer (TR-FRET) assay. Compounds X and Y have the following structures:




TR-FRET monitored the formation of 3,4,5-inositol triphosphate molecule that competed with fluorescently labeled PIP3 for binding to the GRP-1 pleckstrin homology domain protein. An increase in phosphatidylinositide 3-phosphate product resulted in a decrease in TR-FRET signal as the labeled fluorophore was displaced from the GRP-1 protein binding site. Class I PI3K isoforms were expressed and purified as heterodimeric recombinant proteins. All assay reagents and buffers for the TR-FRET assay were purchased from Millipore. PI3K isoforms were assayed under initial rate conditions in the presence of 25 mM Hepes (pH 7.4), and 2× Km ATP (75-500 μM), 2 μM PIP2, 5% glycerol 5 mM MgCl2, 50 mM NaCl, 0.05% (v/v) Chaps, 1 mM dithiothreitol, and 1% (v/v) DMSO at the following concentrations for each isoform: PI3Kα, PI3Kβ, and PI3Kδ between 25 and 50 pM, and PI3Kγ at 2 nM. The compounds of Table 1, Compound X ((S)-2-(1-((9H-purin-6-yl)amino)ethyl)-5-chloro-3-phenylquinazolin-4(3H)-one) and Compound Y ((S)-4-amino-6-((1-(5-chloro-4-oxo-3-phenyl-3,4-dihydroquinazolin-2-yl)ethyl)amino)pyrimidine-5-carbonitrile), were added to the assay solution and incubated for 30 minutes at 25° C. Additionally, compounds 19 to 116 were added to the assay solution and incubated for 30 minutes at 25° C. The reactions were terminated with a final concentration of 10 mM EDTA, 10 nM labeled-PIP3, and 35 nM Europium labeled GRP-1 detector protein before reading TR-FRET on an Envision plate reader (Ex: 340 nm; Em: 615/665 nm; 100 μs delay and 500 μs read window).
The results were normalized based on positive (1 μM wortmanin) and negative (DMSO) controls, and the IC50 values for PI3K α, β, δ, and γ were calculated from the fit of the dose-response curves to a four-parameter equation. These assays generally produced results within 3-fold of the reported mean.
Table 2 summarizes the IC50 (nM) values for PI3K isoform δ (IC50 for PI3K β, α, and γ are not shown). Table 3 summarizes the IC50 (nM) values for PI3K isoform δ (IC50 for PI3K β, α, and γ are not shown). The results indicate that certain compounds of present application inhibit PI3Kδ.
