Description:
3-(5-AMINO-PYRAZIN-2-YL)-BENZENESULFONAMIDE DERIVATIVES AND RELATED COMPOUNDS AS PI3K-GAMMA KINASE INHIBITORS FOR TREATING E.G. CANCER

TECHNICAL FIELD

The present invention provides bridged cyclic compounds that modulate the activity of phosphoinositide 3-kinases-gamma (RI3Kg) and are useful in the treatment of diseases related to the activity of RI3Kg including, for example, autoimmune diseases, cancer,

cardiovascular diseases, and neurodegenerative diseases.

BACKGROUND

The phosphoinositide 3-kinases (PI3Ks) belong to a large family of lipid signaling kinases that phosphorylate phosphoinositides at the D3 position of the inositol ring (Cantley, Science, 2002, 296(5573): 1655-7). PI3Ks are divided into three classes (class I, II, and III) according to their structure, regulation and substrate specificity. Class I PI3Ks, which include RI3Ka, RI3Kb, RI3Kg, and RBKd, are a family of dual specificity lipid and protein kinases that catalyze the phosphorylation of phosphatidylinosito-4,5-bisphosphate (PIP2) giving rise to phosphatidylinosito-3,4,5-trisphosphate (PIP3). PIP3 functions as a second messenger that controls a number of cellular processes, including growth, survival, adhesion and migration. All four class I PI3K isoforms exist as heterodimers composed of a catalytic subunit (pl 10) and a tightly associated regulatory subunit that controls their expression, activation, and subcellular localization. RI3Ka, RBKb, and PI3K5 associate with a regulatory subunit known as p85 and are activated by growth factors and cytokines through a tyrosine kinase- dependent mechanism (Jimenez, et ah, J Biol Chem., 2002, 277(44):4l556-62) whereas

RBKg associates with two regulatory subunits (plOl and p84) and its activation is driven by the activation of G-protein-coupled receptors (Brock, et ah, J Cell Biol., 2003, l60(l):89-99). PBKa and RI3Kb are ubiquitously expressed. In contrast, RBKg and PI3K5 are

predominantly expressed in leukocytes (Vanhaesebroeck, et ah, Trends Biochem Sci., 2005, 30(4): 194-204).

Expression of RBKg is mainly restricted to hematopoietic system, although it can be also detected at lower level in endothelium, heart and brain. RBKg knock-out or kinase dead knock in mice are normal and fertile and do not present any overt adverse phenotypes.

Analysis at the cellular level indicates that RBKg is required for GPCR ligand-induced

PtdINs (3,4,5)P3 production, chemotaxis and respiratory burst in neutrophils. RBKg-null macrophages and dendritic cell exhibit reduced migration towards various chemoattractants. T-cells deficient in RBKg show impaired cytokine production in response to anti-CD3 or Con A stimulation. RBKg working downstream of adenosine A3A receptor is critical for sustained degranulation of mast cells induced by FCsRI cross-linking with IgE. RI3Kg is also essential for survival of eosinophils (Ruckle et ah, Nat. Rev. Drug Discovery , 2006, 5, 903- 918)

Given its unique expression pattern and cellular functions, the potential role of RI3Kg in various autoimmune and inflammatory disease models has been investigated with genetic and pharmacological tools. In asthma and allergy models, RI3Kg mice or mice treated with RI3Kg inhibitor showed a defective capacity to mount contact hypersensitivity and delayed- type hypersensitivity reactions. In these models, RI3Kg was shown to be important for recruitment of neutrophils and eosinopohils to airways and degranulation of mast cells (see e.g. Laffargue et ah, Immunity, 2002, 16, 441-451; Prete et ah, The EMBO Journal, 2004, 23, 3505-3515; Pinho et ah, L. Leukocyte Biology, 2005, 77, 800-810; Thomas et ah, Eur. J. Immunol. 2005, 35, 1283-1291; Doukas et ah, J. Pharmacol. Exp Ther. 2009, 328, 758-765).

In two different acute pancreatitis models, genetic ablation of RI3Kg significantly reduced the extent of acinar cell injury/necrosis and neutrophil infiltration without any impact on secretive function of isolated pancreatic acini (Lupia et ah, Am. J. Pathology, 2004, 165, 2003-2011). RI3Kg mice were largely protected in four different models of rheumatoid arthritis (CIA, a-CII-IA, K/BxN serum transfer and TNF transgenic) and RI3Kg inhibition suppressed the progression of joint inflammation and damage in the CIA and a-CII-IA models (see e.g., Camps et ah, Nat. Medicine, 2005, 11, 939-943; Randis et ah, Eur. J.

Immunol, 2008, 38, 1215-1224; Hayer et ak, FASB J, 2009, 4288-4298). In the MKL-lpr mouse model of human systemic lupus erythematous, inhibition of RI3Kg reduced glomerulonephritis and prolonged life span (Barber et ak, Nat. Medicine, 2005, 9, 933-935).

There is evidence suggesting that chronic inflammation due to infiltration by myeloid-derived cells is a key component in the progression of neurodegeneration diseases, such as Alzheimer’s disease (AD) (Giri et ak, Am. J. Physiol. Cell Physiol., 2005, 289, C264- C276; El Khoury et ak, Nat. Med., 2007, 13, 432-438). In line with this suggestion, RI3Kg inhibition was shown to attenuate Ap(l-40)-induced accumulation of activated astrocytes and microglia in the hippocampus and prevent the peptide-induced congnitive deficits and synaptic dysfunction in a mouse model of AD (Passos et ak, Brain Behav. Immun. 2010, 24, 493-501). RI3Kg deficiency or inhibition also was shown to delay onset and alleviate symptoms in experimental autoimmune encephalomyelitis in mice, a mouse model of human multiple sclerosis, which is another form of neurodegeneration disease (see e.g., Rodrigues et ak, J. Neuroimmunol . 2010, 222, 90-94; Berod et ak, Euro. J. Immunol. 2011, 41, 833-844; Comerford et ak, PLOS one, 2012, 7, e45095; Li et ak, Neuroscience, 2013, 253, 89-99). Chronic inflammation has been formally recognized as one of the hallmarks for many different types of cancers. Accordingly, selective anti-inflammatory drugs represent a novel class of anti -cancer therapies (Hanahan and Weinberg, Cell, 2011, 144, 646-674). Since RI3Kg is reported to mediate various inflammatory processes, its role as an immune oncology target has also been investigated. A recent study reported that RI3Kg deficiency suppressed tumor growth in the syngeneic models of lung cancer, pancreatic cancer and melanoma (LLC, PAN02 and B 16). RI3Kg deficiency or inhibition also inhibited tumor growth in a spontaneous breast cancer model (Schmid et al., Cancer Cell, 2011, 19, 715-727). A further study reported that RI3Kg deficiency could ameliorate inflammation and tumor growth in mice having colitis-associated colon cancer, (Gonzalez-Garcia et al., Gastroenterology, 2010, 138, 1373-1384). Detailed mechanistic analysis indicates that tumor infiltration by CD1 lb + myeloid cells can cause protumorigenic inflammation at tumor sites and RI3Kg in the myeloid cells is critical in mediating signaling of various chemoattractants in bring the cells to the tumor (Schmid et al., Cancer Cell, 2011, 19, 715-727). Other studies suggest that RI3Kg is also required for differentiation of naive myeloid cells into M2 macrophges at tumor sites.

M2 macrophages promote tumor growth and progression by secreting immunosuppressive factors such arginase 1, which depletes the tumor microenvironment of arginine, thereby promoting T-cell death and NK cell inhibition (Schmidt et al., Cancer Res. 2012, 72 (Suppl 1: Abstract, 411, Kaneda et al., Cancer Res., 74 (Suppl 19: Abstact 3650)).

In addition to its potential role in promoting protumorigenic microenvironment,

RI3Kg may play a direct role in cancer cells. RI3Kg is reported to be required for signaling from the Kaposi’s sarcoma-associated herpevirus encoded vGPCR oncogene and tumor growth in a mouse model of sarcoma (Martin et al., Cancer Cell, 2011, 19, 805-813). RI3Kg was also suggested to be required for growth of T-ALL (Subramanjam et al., Cancer Cell, 2012, 21, 459-472), PDAC and HCC cells (Falasca and Maffucci, Frontiers in Physiology, 2014, 5, 1-10). Moreover, in a survey of driver mutations in pancreatic cancer, RI3Kg gene was found to contain second highest scoring predicted driven mutation (R839C) among the set of genes not previously identified as a driver in pancreatic cancer (Carter et al., Cancer Biol. Ther. 2010, 10, 582-587).

Finally, RI3Kg deficiency also has been reported to offer protection to experimental animals in different cardiovascular disease models. For examples, lack of RI3Kg would reduce angiotension-evoked smooth muscle contraction and, therefore, protect mice from angiotension-induced hypertension (Vecchione et al., J. Exp. Med. 2005, 201, 1217-1228). In rigorous animal myocardial infarction models, RI3Kg inhibition provided potent cardioprotection, reducing infarct development and preserving myocardial function (Doukas et ak, Proc. Natl. Acad. Sci. USA, 2006, 103, 19866-19871).

For these reasons, there is a need to develop new RI3Kg inhibitors that can be used for the treatment of diseases such as cancer, autoimmune disorders, and inflammatory and cardiac diseases. This application is directed to this need and others.

Pharmaceutical Formulations and Dosage Forms

When employed as pharmaceuticals, the compounds of the disclosure can be administered in the form of pharmaceutical compositions. These compositions can be prepared in a manner well known in the pharmaceutical art, and can be administered by a variety of routes, depending upon whether local or systemic treatment is desired and upon the area to be treated. Administration may be topical (including transdermal, epidermal, ophthalmic and to mucous membranes including intranasal, vaginal and rectal delivery), pulmonary (e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal or intranasal), oral or parenteral. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal intramuscular or injection or infusion; or intracranial, e.g., intrathecal or intraventricular, administration. Parenteral administration can be in the form of a single bolus dose, or may be, for example, by a continuous perfusion pump. Pharmaceutical compositions and formulations for topical administration may include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable. This disclosure also includes pharmaceutical compositions which contain, as the active ingredient, the compound of the disclosure or a pharmaceutically acceptable salt thereof, in combination with one or more pharmaceutically acceptable carriers (excipients).

In some embodiments, the composition is suitable for topical administration. In making the compositions of the disclosure, the active ingredient is typically mixed with an excipient, diluted by an excipient or enclosed within such a carrier in the form of, for example, a capsule, sachet, paper, or other container. When the excipient serves as a diluent, it can be a solid, semi-solid, or liquid material, which acts as a vehicle, carrier or medium for the active ingredient. Thus, the compositions can be in the form of tablets, pills, powders, lozenges, sachets, cachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, suppositories, sterile injectable solutions, and sterile packaged powders.

In preparing a formulation, the active compound can be milled to provide the appropriate particle size prior to combining with the other ingredients. If the active compound is substantially insoluble, it can be milled to a particle size of less than 200 mesh. If the active compound is substantially water soluble, the particle size can be adjusted by milling to provide a substantially uniform distribution in the formulation, e.g. about 40 mesh.

The compounds of the disclosure may be milled using known milling procedures such as wet milling to obtain a particle size appropriate for tablet formation and for other formulation types. Finely divided (nanoparticulate) preparations of the compounds of the disclosure can be prepared by processes known in the art, e.g., see International App. No. WO 2002/000196.

Some examples of suitable excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, water, syrup, and methyl cellulose. The formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents. The compositions of the disclosure can be formulated so as to provide quick, sustained or delayed release of the active ingredient after administration to the patient by employing procedures known in the art.

The compositions can be formulated in a unit dosage form, each dosage containing from about 5 to about 1000 mg (1 g), more usually about 100 to about 500 mg, of the active ingredient. The term "unit dosage forms" refers to physically discrete units suitable as unitary dosages for human subjects and other mammals, each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect, in association with a suitable pharmaceutical excipient.

In some embodiments, the compositions of the disclosure contain from about 5 to about 50 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 5 to about 10, about 10 to about 15, about 15 to about 20, about 20 to about 25, about 25 to about 30, about 30 to about 35, about 35 to about 40, about 40 to about 45, or about 45 to about 50 mg of the active ingredient.

In some embodiments, the compositions of the disclosure contain from about 50 to about 500 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 50 to about 100, about 100 to about 150, about 150 to about 200, about 200 to about 250, about 250 to about 300, about 350 to about 400, or about 450 to about 500 mg of the active ingredient.

In some embodiments, the compositions of the disclosure contain from about 500 to about 1000 mg of the active ingredient. One having ordinary skill in the art will appreciate that this embodies compositions containing about 500 to about 550, about 550 to about 600, about 600 to about 650, about 650 to about 700, about 700 to about 750, about 750 to about 800, about 800 to about 850, about 850 to about 900, about 900 to about 950, or about 950 to about 1000 mg of the active ingredient.

Similar dosages may be used of the compounds described herein in the methods and uses of the disclosure.

The active compound can be effective over a wide dosage range and is generally administered in a pharmaceutically effective amount. It will be understood, however, that the amount of the compound actually administered will usually be determined by a physician, according to the relevant circumstances, including the condition to be treated, the chosen route of administration, the actual compound administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical excipient to form a solid preformulation composition containing a homogeneous mixture of a compound of the present disclosure. When referring to these preformulation compositions as homogeneous, the active ingredient is typically dispersed evenly throughout the composition so that the composition can be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules. This solid

preformulation is then subdivided into unit dosage forms of the type described above containing from, for example, about 0.1 to about 1000 mg of the active ingredient of the present disclosure.

The tablets or pills of the present disclosure can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permit the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.

The liquid forms in which the compounds and compositions of the present disclosure can be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil, or peanut oil, as well as elixirs and similar pharmaceutical vehicles.

Compositions for inhalation or insufflation include solutions and suspensions in pharmaceutically acceptable, aqueous or organic solvents, or mixtures thereof, and powders. The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as described supra. In some embodiments, the compositions are administered by the oral or nasal respiratory route for local or systemic effect. Compositions can be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device can be attached to a face mask, tent, or intermittent positive pressure breathing machine. Solution, suspension, or powder compositions can be administered orally or nasally from devices which deliver the formulation in an appropriate manner.

Topical formulations can contain one or more conventional carriers. In some embodiments, ointments can contain water and one or more hydrophobic carriers selected from, for example, liquid paraffin, polyoxyethylene alkyl ether, propylene glycol, white Vaseline, and the like. Carrier compositions of creams can be based on water in combination with glycerol and one or more other components, e.g. glycerinemonostearate, PEG- glycerinemonostearate and cetylstearyl alcohol. Gels can be formulated using isopropyl alcohol and water, suitably in combination with other components such as, for example, glycerol, hydroxyethyl cellulose, and the like. In some embodiments, topical formulations contain at least about 0.1, at least about 0.25, at least about 0.5, at least about 1, at least about 2, or at least about 5 wt % of the compound of the disclosure. The topical formulations can be suitably packaged in tubes of, for example, 100 g which are optionally associated with instructions for the treatment of the select indication, e.g., psoriasis or other skin condition.

The amount of compound or composition administered to a patient will vary depending upon what is being administered, the purpose of the administration, such as prophylaxis or therapy, the state of the patient, the manner of administration, and the like. In therapeutic applications, compositions can be administered to a patient already suffering from a disease in an amount sufficient to cure or at least partially arrest the symptoms of the disease and its complications. Effective doses will depend on the disease condition being treated as well as by the judgment of the attending clinician depending upon factors such as the severity of the disease, the age, weight and general condition of the patient, and the like.

The compositions administered to a patient can be in the form of pharmaceutical compositions described above. These compositions can be sterilized by conventional sterilization techniques, or may be sterile filtered. Aqueous solutions can be packaged for use as is, or lyophilized, the lyophilized preparation being combined with a sterile aqueous carrier prior to administration. The pH of the compound preparations typically will be between 3 and 11, more preferably from 5 to 9 and most preferably from 7 to 8. It will be understood that use of certain of the foregoing excipients, carriers, or stabilizers will result in the formation of pharmaceutical salts.

The therapeutic dosage of a compound of the present disclosure can vary according to, for example, the particular use for which the treatment is made, the manner of

administration of the compound, the health and condition of the patient, and the judgment of the prescribing physician. The proportion or concentration of a compound of the disclosure in a pharmaceutical composition can vary depending upon a number of factors including dosage, chemical characteristics (e.g., hydrophobicity), and the route of administration. For example, the compounds of the disclosure can be provided in an aqueous physiological buffer solution containing about 0.1 to about 10% w/v of the compound for parenteral administration. Some typical dose ranges are from about 1 pg/kg to about 1 g/kg of body weight per day. In some embodiments, the dose range is from about 0.01 mg/kg to about 100 mg/kg of body weight per day. The dosage is likely to depend on such variables as the type and extent of progression of the disease or disorder, the overall health status of the particular patient, the relative biological efficacy of the compound selected, formulation of the excipient, and its route of administration. Effective doses can be extrapolated from dose-response curves derived from in vitro or animal model test systems. The compositions of the disclosure can further include one or more additional pharmaceutical agents such as a chemotherapeutic, steroid, anti-inflammatory compound, or immunosuppressant, examples of which are listed herein.

Labeled Compounds and Assay Methods

Another aspect of the present disclosure relates to labeled compounds of the disclosure (radio-labeled, fluorescent-labeled, etc.) that would be useful not only in imaging techniques but also in assays, both in vitro and in vivo, for localizing and quantitating PI3K in tissue samples, including human, and for identifying PI3K ligands by inhibition binding of a labeled compound. Substitution of one or more of the atoms of the compounds of the present disclosure can also be useful in generating differentiated ADME (Adsorption, Distribution, Metabolism and Extretion.) Accordingly, the present disclosure includes PI3K assays that contain such labeled or substituted compounds.

The present disclosure further includes isotopically-labeled compounds of the disclosure. An“isotopically” or“radio -labeled” compound is a compound of the disclosure where one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (/. e. , naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present disclosure include but are not limited to 2 H (also written as D for deuterium), 3 H (also written as T for tritium), n C, 13 C, 14 C, 13 N, 15 N, 15 0, 17 0, 18 0, 18 F, 35 S, 36 C1, 82 Br, 75 Br, 76 Br, 77 Br, 123 I, 124 I, 125 I and 131 I. For example, one or more hydrogen atoms in a compound of the present disclosure can be replaced by deuterium atoms (e.g., one or more hydrogen atoms of a Ci- 6 alkyl group of Formula (I) can be optionally substituted with deuterium atoms, such as - CD 3 being substituted for -CFF).

One or more constituent atoms of the compounds presented herein can be replaced or substituted with isotopes of the atoms in natural or non-natural abundance. In some embodiments, the compound includes at least one deuterium atom. For example, one or more hydrogen atoms in a compound presented herein can be replaced or substituted by deuterium (e.g., one or more hydrogen atoms of a Ci- 6 alkyl group can be replaced by deuterium atoms, such as -CD 3 being substituted for -CFF). In some embodiments, the compound includes two or more deuterium atoms. In some embodiments, the compound includes 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23 or 24 deuterium atoms. In some embodiments, all of the hydrogen atoms in a compound can be replaced or substituted by deuterium atoms. Synthetic methods for including isotopes into organic compounds are known in the art (Deuterium Labeling in Organic Chemistry by Alan F. Thomas (New York, NY., Appleton-Century-Crofts, 1971; The Renaissance of H/D Exchange by Jens Atzrodt, Volker Derdau, Thorsten Fey and Jochen Zimmermann, Angew. Chem. Int. Ed. 2007, 7744-7765; The Organic Chemistry of Isotopic Labelling by James R. Hanson, Royal Society of

Chemistry, 2011). Isotopically labeled compounds can used in various studies such as NMR spectroscopy, metabolism experiments, and/or assays.

Substitution with heavier isotopes, such as deuterium, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances (see e.g., A. Kerekes et.al. J. Med. Chem. 2011, 54, 201-210; R. Xu et.al. J. Label Compd.

Radiopharm. 2015, 58, 308-312). In particular, substitution at one or more metabolism sites may afford one or more of the therapeutic advantages.

The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro PI3K labeling and competition assays, compounds that incorporate 3 H, 14 C, 82 Br, 125 I, m I or 35 S can be useful. For radio -imaging applications n C, 18 F, 125 I, 123 I, 124 I, 131 1, 75 Br, 76 Br or 77 Br can be useful.

It is understood that a“radio-labeled” or“labeled compound” is a compound that has incorporated at least one radionuclide. In some embodiments the radionuclide is selected from the group consisting of 3 H, 14 C, 125 1, 35 S and 82 Br.

The present disclosure can further include synthetic methods for incorporating radio isotopes into compounds of the disclosure. Synthetic methods for incorporating radio-isotopes into organic compounds are well known in the art, and an ordinary skill in the art will readily recognize the methods applicable for the compounds of disclosure.

A labeled compound of the disclosure can be used in a screening assay to

identify/evaluate compounds. For example, a newly synthesized or identified compound (/. e. , test compound) which is labeled can be evaluated for its ability to bind a PI3K by monitoring its concentration variation when contacting with the PI3K, through tracking of the labeling. For example, a test compound (labeled) can be evaluated for its ability to reduce binding of another compound which is known to bind to a PI3K (i.e. , standard compound). Accordingly, the ability of a test compound to compete with the standard compound for binding to the PI3K directly correlates to its binding affinity. Conversely, in some other screening assays, the standard compound is labeled and test compounds are unlabeled. Accordingly, the concentration of the labeled standard compound is monitored in order to evaluate the competition between the standard compound and the test compound, and the relative binding affinity of the test compound is thus ascertained.

Kits

The present disclosure also includes pharmaceutical kits useful, for example, in the treatment or prevention of PI3K-associated diseases or disorders, such as cancer, which include one or more containers containing a pharmaceutical composition comprising a therapeutically effective amount of a compound of the disclosure. Such kits can further include, if desired, one or more of various conventional pharmaceutical kit components, such as, for example, containers with one or more pharmaceutically acceptable carriers, additional containers, etc., as will be readily apparent to those skilled in the art. Instructions, either as inserts or as labels, indicating quantities of the components to be administered, guidelines for administration, and/or guidelines for mixing the components, can also be included in the kit.

The invention will be described in greater detail by way of specific examples. The following examples are offered for illustrative purposes, and are not intended to limit the invention in any manner. Those of skill in the art will readily recognize a variety of non- critical parameters which can be changed or modified to yield essentially the same results. The compounds of the Examples have been found to be RI3Kg inhibitors according to at least one assay described herein.

EXAMPLES

Preparatory LC-MS purifications of some of the compounds prepared were performed on Waters mass directed fractionation systems. The basic equipment setup, protocols, and control software for the operation of these systems have been described in detail in the literature (see e.g.“Two-Pump At Column Dilution Configuration for Preparative LC-MS”, K. Blom, J. Combi. Chem., 4, 295 (2002);“Optimizing Preparative LC-MS Configurations and Methods for Parallel Synthesis Purification”, K. Blom, R. Sparks, J. Doughty, G. Everlof, T. Haque, A. Combs, J.
