Field of Invention

[0002] The present invention is directed to inhibitors of phosphatidylinositol-5-phosphate- 4-kinase (PI5P4K) useful in the treatment of diseases or disorders associated with PI5P4K enzymes. In particular, the invention is concerned with compounds and compositions inhibiting PI5P4K, methods of treating diseases or disorders associated with PI5P4K, and methods of synthesis of these compounds.

Background of the Invention

[0003] A minor but ubiquitous component of cells, phosphoinositol lipids are pivotal players in many intracellular signal transduction pathways. Phosphoinositol lipids are formed when phosphatidylinositol (Ptdlns) is converted, by the catalytic action of lipid kinases, to polyphosphoinositides. As a prototypic example, the membrane associated phospholipid, phosphatidylinositol-4,5-bisphosphate (PtdIns(4,5)P2), is formed by two successive phosphorylations of Ptdlns by the phosphatidylinositol phosphate kinases (PIP kinases).

[0004] PtdIns(4,5)P2 is a substrate for phospholipase C (PLC) and is converted into the second messengers inositol-l,4,5-trisphosphate and diacylglycerol (DAG). Phosphoinositides are involved in regulating a broad spectrum of activities from cytoskeletal assembly and motility to vesicle trafficking and exocytosis to transduction of intracellular signals including stimulating the release of intracellular calcium stores (Hinchliffe et al, Biochem. Soc. Trans., 1999, 27, 657-661).

[0005] PIP kinases comprise a unique and promiscuous family of enzymes that catalyze the production of poly-phosphorylated inositol lipids from mono-phosphorylated phosphoinositides. isolation and purification of several different PIP kinase enzymes able to catalyze phosphorylation of phosphatidylinositol 4-phosphate and produce PtdIns(4,5)P2 led to the further categorization of these enzymes, dubbed the phosphatidylinositol 4-phosphate 5- kinases (PIP5Ks), into two types having different activities. The PIP kinases have no homology to other lipid or protein kinases at the primary sequence level, and are distinguished from each other by their lack of immuno-cross reactivity and by the fact that type I PIP5Ks are stimulated in vitro by phosphatidic acid, whereas the type II PIP5Ks are not. Furthermore, the recent discovery that the type II PTP5Ks are able to phosphorylate multiple lipid substrates in vitro suggests that this family of kinases is potentially able to generate several distinct, often subcellularly compartmentalized, phosphoinositol products for regulation of a variety of physiologically important processes (Hinchliffe et al, Biochem. Soc. Trans., 1999, 27, 657- 661).

[0006] One particular species of PI, phosphatidylinositol 5-phosphate (PI5P), has been implicated in the regulation of the tumor suppressor ING2 and the oncogene AKT. The phosphatidylinositol 5-phosphate 4-kinase (PI5P4K) family (a, b, g isoforms) catalyzes the conversion of PI5P to PI4, 5 P2. These enzymes therefore represent one means by which cells can regulate endogenous PI5P levels. Mice deficient for RI5R4Kb (RI5R4Kb-/-) have been shown to exhibit enhanced insulin sensitivity and activation of AKT in skeletal muscle.

[0007] The pharmacological modulation of PIP5KII-beta activity and/or expression is therefore believed to be an appropriate point of therapeutic intervention in pathological conditions in which cell differentiation, proliferation, and/or motility are compromised, such as cancer or inflammation, and in metabolic disorders.

[0008] Currently, there are no known therapeutic agents which effectively inhibit the synthesis of PIP5KII-beta. Inhibition of PI5P4K with small molecule inhibitors, therefore, has the potential to be a treatment for cancers and other disorders. For this reason, there remains a considerable need for novel and potent small molecule inhibitors and agents capable of effectively inhibiting PIP5KII-beta function.

[0025] The details of the invention are set forth in the accompanying description below. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, illustrative methods and materials are now described. Other features, objects, and advantages of the invention will be apparent from the description and from the claims. In the specification and the appended claims, the singular forms also include the plural unless the context clearly dictates otherwise. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. All patents and publications cited in this specification are incorporated herein by reference in their entireties.

Definitions

[0026] The articles "a" and "an" are used in this disclosure to refer to one or more than one (i.e., to at least one) of the grammatical object of the article. By way of example, "an element" means one element or more than one element. [0027] The term "and/or" is used in this disclosure to mean either "and" or "or" unless indicated otherwise.

[0028] The term“optionally substituted” is understood to mean that a given chemical moiety (e.g., an alkyl group) can (but is not required to) be bonded other substituents (e.g, heteroatoms). For instance, an alkyl group that is optionally substituted can be a fully saturated alkyl chain (i.e.. a pure hydrocarbon). Alternatively, the same optionally substituted alkyl group can have one or more substituents different from hydrogen. For instance, it can, at any point along the chain be bounded to a halogen atom, a hydroxyl group, or any other substituent described herein. Thus the term“optionally substituted” means that a given chemical moiety has the potential to contain other functional groups, but does not necessarily have any further functional groups. Suitable substituents used in the optional substitution of the described groups include, without limitation, halogen, oxo, -OH, -CN, -COOH, -CH2CN, -O-(C i-CT) alkyl, (Oi-Ob) alkyl, (Oi-Ob) alkoxy, (Oi-Ob) haloalkyl, (Oi-Ob) haloalkoxy, -0-(C2-C6) alkenyl, -0-(C ₂ -C ₆ ) alkynyl, (C ₂ -Ce) alkenyl, (C ₂ -Ce) alkynyl, -OH, -OP(0)(OH) ₂ , - OC(0)(Ci-Ce) alkyl, -C(0)(Ci-Ce) alkyl, -0C(0)0(Ci-Ce) alkyl, -NH ₂ , -NH((Ci-Ce) alkyl), -N((Ci-Ce) alkyl) ₂ , -NHC(0)(Ci-Ce) alkyl, -C(0)NH(Ci-Ce) alkyl, -S(0) ₂ (Ci-Ce) alkyl, - S(0)NH(Ci-C6)alkyl, and -S(0)N((Ci-C6)alkyl) ₂ . The substituents can themselves be optionally substituted. “Optionally substituted” as used herein also refers to substituted or unsubstituted whose meaning is described below.

[0029] As used herein, the term“substituted” means that the specified group or moiety bears one or more suitable substituents wherein the substituents may connect to the specified group or moiety at one or more positions. For example, an aryl substituted with a cycloalkyl may indicate that the cycloalkyl connects to one atom of the aryl with a bond or by fusing with the aryl and sharing two or more common atoms.

[0030] As used herein, the term“unsubstituted” means that the specified group bears no substituents.

[0031] Unless otherwise specifically defined, the term "aryl" refers to cyclic, aromatic hydrocarbon groups that have 1 to 3 aromatic rings, including monocyclic or bicyclic groups such as phenyl, biphenyl or naphthyl. Where containing two aromatic rings (bicyclic, etc.), the aromatic rings of the aryl group may be joined at a single point (e.g., biphenyl), or fused (e.g, naphthyl). The aryl group may be optionally substituted by one or more substituents, e.g, 1 to 5 substituents, at any point of attachment. Exemplary substituents include, but are not limited to,

[0032] -H, -halogen, -0-(Ci-Ce)alkyl, (Ci-Ce)alkyl, -0-(C2-C ₆ )alkenyl, -0-(C ₂ -C ₆ ) alkynyl, (C2-C ₆ )alkenyl, (C ₂ -C6)alkynyl, -OH, -0P(0)(0H) ₂ , -OC(0)(Ci-C ₆ )alkyl, - C(0)(Ci-Ce) alkyl, -0C(0)0(Ci-C ₆ )alkyl, -NH ₂ , -NH((Ci-C ₆ )alkyl), -N((Ci-C ₆ )alkyl)2, - S(0) ₂ -(Ci-C ₆ ) alkyl, -S(0)NH(Ci-C6)alkyl, and -S(0)N((Ci-C6)alkyl)2. The substituents can themselves be optionally substituted. Furthermore when containing two fused rings the aryl groups herein defined may have an unsaturated or partially saturated ring fused with a fully saturated ring. Exemplary ring systems of these aryl groups include, but are not limited to, phenyl, biphenyl, naphthyl, anthracenyl, phenalenyl, phenanthrenyl, indanyl, indenyl, tetrahydronaphthalenyl, tetrahydrobenzoannulenyl, and the like.

[0033] Unless otherwise specifically defined, "heteroaryl" means a monovalent monocyclic or a polycyclic aromatic radical of 5 to 24 ring atoms, containing one or more ring heteroatoms selected from N, O, S, P, or B, the remaining ring atoms being C. A polycyclic aromatic radical includes two or more fused rings and may further include two or more spiro- fused rings, e.g., bicyclic, tricyclic, tetracyclic, and the like. Unless otherwise specifically defined,“fused” means two rings sharing two ring atoms. Unless otherwise specifically defined,“spiro-fused” means two rings sharing one ring atom. Heteroaryl as herein defined also means a bicyclic heteroaromatic group wherein the heteroatom is selected from N, O, S, P, or B. Heteroaryl as herein defined also means a tricyclic heteroaromatic group containing one or more ring heteroatoms selected fromN, O, S, P, or B. Heteroaryl as herein defined also means a tetracyclic heteroaromatic group containing one or more ring heteroatoms selected from N, O, S, P, or B.

For example, if a compound of the invention incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the invention. Each compound herein disclosed includes all the enantiomers that conform to the general structure of the compound. The compounds may be in a racemic or enantiomerically pure form, or any other form in terms of stereochemistry. The assay results may reflect the data collected for the racemic form, the enantiomerically pure form, or any other form in terms of stereochemistry.

[0385] Diastereomeric mixtures can be separated into their individual diastereomers on the basis of their physical chemical differences by methods well known to those skilled in the art, such as, for example, by chromatography and/or fractional crystallization. Enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with an appropriate optically active compound (e.g., chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers. Also, some of the compounds of the invention may be atropisomers (e.g., substituted biaryls) and are considered as part of this invention. Enantiomers can also be separated by use of a chiral HPLC column.

[0386] It is also possible that the compounds of the invention may exist in different tautomeric forms, and all such forms are embraced within the scope of the invention. Also, for example, all keto-enol and imine-enamine forms of the compounds are included in the invention.

[0387] All stereoisomers (for example, geometric isomers, optical isomers and the like) of the present compounds (including those of the salts, solvates, esters and prodrugs of the compounds as well as the salts, solvates and esters of the prodrugs), such as those which may exist due to asymmetric carbons on various substituents, including enantiomeric forms (which may exist even in the absence of asymmetric carbons), rotameric forms, atropisomers, and diastereomeric forms, are contemplated within the scope of this invention, as are positional isomers (such as, for example, 4-pyridyl and 3-pyridyl). (For example, if a compound of Formula (I) incorporates a double bond or a fused ring, both the cis- and trans-forms, as well as mixtures, are embraced within the scope of the invention. Also, for example, all keto-enol and imine-enamine forms of the compounds are included in the invention.) Individual stereoisomers of the compounds of the invention may, for example, be substantially free of other isomers, or may be admixed, for example, as racemates or with all other, or other selected, stereoisomers. The chiral centers of the present invention can have the S or R configuration as defined by the IUPAC 1974 Recommendations. The use of the terms“salt”,“solvate”,“ester,” “prodrug” and the like, is intended to equally apply to the salt, solvate, ester and prodrug of enantiomers, stereoisomers, rotamers, tautomers, positional isomers, racemates or prodrugs of the inventive compounds.

[0388] The compounds of Formula I may form salts which are also within the scope of this invention. Reference to a compound of the Formula herein is understood to include reference to salts thereof, unless otherwise indicated.

[0389] The present invention relates to compounds which are modulators of PI5P4K. In one embodiment, the compounds of the present invention are inhibitors of PI5P4K.

[0390] The invention is directed to compounds as described herein and pharmaceutically acceptable salts, hydrates, solvates, prodrugs, stereoisomers, or tautomers thereof, and pharmaceutical compositions comprising one or more compounds as described herein, or pharmaceutically acceptable salts, hydrates, solvates, prodrugs, stereoisomers, or tautomers thereof.

Method of Synthesizing the Compounds [0391] The compounds of the present invention may be made by a variety of methods, including standard chemistry. Suitable synthetic routes are depicted in the Schemes given below.

[0392] The compounds of Formula (I) may be prepared by methods known in the art of organic synthesis as set forth in part by the following synthetic schemes. In the schemes described below, it is well understood that protecting groups for sensitive or reactive groups are employed where necessary in accordance with general principles or chemistry. Protecting groups are manipulated according to standard methods of organic synthesis (T. W. Greene and P. G. M. Wuts, "Protective Groups in Organic Synthesis", Third edition, Wiley, New York 1999). These groups are removed at a convenient stage of the compound synthesis using methods that are readily apparent to those skilled in the art. The selection processes, as well as the reaction conditions and order will be readily apparent to those skilled in the art and they will recognize if a stereocenter exists in the compounds of Formula (I). Accordingly, the present invention includes both possible stereoisomers (unless specified in the synthesis) and includes not only racemic compounds but the individual enantiomers and/or diastereomers as well. When a compound is desired as a single enantiomer or diastereomer, it may be obtained by stereospecific synthesis or by resolution of the final product or any convenient intermediate. Resolution of the final product, an intermediate, or a starting material may be affected by any suitable method known in the art. See, for example, "Stereochemistry of Organic Compounds" by E. L. Eliel, S. H. Wilen, and L. N. Mander (Wiley-lnterscience, 1994).

[0393] The compounds described herein may be made from commercially available starting materials or synthesized using known organic, inorganic, and/or enzymatic processes.

If enantiomerically pure or enriched compound (II) is used in this reaction, an enantiomerically pure or enantiomerically enriched compound (I) is obtained. [0397] Compounds of formula (II) and B-NH2 may be commercially available compounds, or known in the literature, or they are prepared by standard processes known in the art. A compound of formula (I), (II) or B-NH2 may be separated into its enantiomers by standard processes known in the art by for example chromatography on a chiral stationary phase.
