[0001] THIAZOLO TETRAHYDROCHINOLINE COMPOUNDS AS CLASS II PHOSPHOINOSITIDE 3-KINASE INHIBITORS

[0002] DESCRIPTION

[0003] The invention is in the field of biochemistry and medicine relates to chemical compounds useful as inhibitors of class II phosphoinositide 3-kinase (PI3K) signalling. The invention further relates to the medical use of inhibitors of class II phosphoinositide 3-kinase (PI3K) signalling in the treatment of medical conditions associated with defective and / or pathologic class II phosphoinositide 3-kinase (PI3K) signaling such as stroke, a cardiovascular disease related to endothelial cell dysfunction, cancer, cancer metastasis, myopathy and diabetes. The invention further relates to the medical use of inhibitors of signalling of the beta isoform of class II phosphoinositide 3-kinase (PI3K-2b) in the treatment of medical conditions associated with defective and / or pathologic signaling of the beta isoform of class II phosphoinositide 3-kinase (PI3K-C2b).

[0004] BACKGROUND OF THE INVENTION

[0005] The phosphoinositide 3-kinases (PI3Ks) are a family of lipid kinases central to regulating a wide range of important intracellular processes. PI3Ks orchestrate cell responses including mitogenic signaling, cell survival and growth, metabolic control, vesicular trafficking, degranulation, cytoskel- etal rearrangement and migration. PI3Ks catalyze the phosphorylation of the 3-OH group on the inositol ring of phosphatidylinositol. Based on substrate preference, amino acid sequence, and structure, three classes of PI3Ks are identified.

[0006] Class I PI3Ks are the earliest discovered PI3Ks. They form hetero-dimers by association of a catalytic subunit and a regulatory subunit that produce P I (3 ,4,5)P3. Class I PI3Ks are further classified into class IA (p110a, p, and 5) and class IB (p110y), based on distinct regulatory subunits (Figure 1). The structural similarity between kinase domains of class I PI3Ks and protein kinases implies that PI3Ks have protein kinase activity in addition to lipid kinase activity.

[0007] Class II phosphoinositide 3-kinases (PI3Ks) control multiple cellular functions ranging from membrane and actin dynamics to cell signaling via synthesis of 3'-phosphorylated inositol phospholipids. In contrast to class I, relatively little is known about class II PI3K. Class II PI3Ks produce PI(3)P or PI(3,4)P2, with varying levels of efficiency that may be related to isoform and cell type. There are three class II PI3K isoforms (PI3KC2oc, PI3KC2P, and PI3KC2y) in vertebrates, but only one member exists in worm and fly. Similar to the catalytic subunit of class I PI3Ks, all class II isoforms contain a Ras binding domain (RBD), a C2 domain (C2), a helical domain (HD), and a kinase domain, but have unique disordered regions in their N-terminus and are extended by two lipid binding domains (PX and C2 domain) at their C-terminus. Unlike class I PI3K, class II PI3K kinases lack regulatory subunits and act as monomers.

[0008] Class II PI3K isoforms have been demonstrated to couple signaling to membrane traffic. This indicates that distinct mechanisms serve to recruit PI3KII and that their lipid product has unique roles [PI(3)P and / or PI(3,4)P2]. Recently, the a isoform has been shown to synthesize PI(3,4)P2 on endocytic pits at the plasma membrane, where PI(3,4)P2 is required for membrane constriction prior to vesicle fission (Posor et al, Nature, 2013, 499, 233-237) and is required to internalize VEGF receptor in endothelial cells (Yoshioka et al., Nat. Med., 2012, 18, 1560-1569). Besides, PI3KC2oc knock-down impairs autophagy at least in some cells and the maturation of endocytic vesicles. PI3KC2oc can also generate PI(3)P and regulate the formation of a PI(3)P pool at peri- centriolar recycling endosomes (PRE) required for Rabi 1 and Shh pathway activation and primary cilia formation.

[0009] The activity of the beta isoform of class II PI3K (PI3KC2P, also termed PI3K-C2b) is associated with endocytosis, proliferation and glucose metabolism. Moreover, the beta isoform regulates nutrient signaling by suppressing mTORCI signaling via local production of PI(3,4)P2 at late endosomes or lysosomes (Marat et al, Science, 2017, 356, 968-972).

[0010] Endothelial-specific PI3KC2a knock-out mice display a vascular barrier function defect indicating that PI3KC2a is involved in angiogenesis (Yoshioka et al., Endothelial PI3K-C2alpha, a class II PI3K, has an essential role in angiogenesis and vascular barrier function. Nat. Med. 2012, 18, 1560-1569). In addition, the liver-specific C2y isoform has recently been shown to produce an endosomal PI(3,4)P2 pool needed for sustained Akt2 activation following insulin stimulation (Braccini et al., Nat. Commun. 2015, 6, 7400). Based on data accumulated to this point in time, class II PI3Ks appear to be involved in cancer, cardiovascular disease, myopathy and diabetes, amongst other diseases (Falasca et al, J. Med. Chem. 2016, 60, 47-65).

[0011] Cell permeable small-molecule inhibitors of kinases are excellent tools to directly and quickly unravel the functional consequences of kinase inactivity and represent useful medical agents. A key challenge for the generation of such inhibitors is their specificity. For PI3Ks, the two widely used primary pharmacological tools available, wortmannin and LY294002, have off-target effects on other members of this family. Therefore, during the past decade more chemotypically diverse small molecule inhibitors have been developed in order to specifically target specific PI3K isoforms.

[0012] For a spectrum of PI3K inhibitors with different degrees of selectivity, different chemotypes have been observed. The most selective compounds include the quinazolinone purine inhibitors (e.g. TGX-115, TGX286, and PIK-108) for PI3K 8 and imidazopyridine inhibitors (e.g. PIK75) for PI3K a (Figure 2A). These compounds exhibit > 100-fold selectivity between their primary targets and other class I PI3Ks. Other chemotypes of inhibitors (i.e. aryl thiazolidinones, pyridinylfuranopyrim- idines, phenylthiazoles, and imidazoquinazolines) were found to inhibit multiple PI3Ks to a variable extent. Additional class I PI3K inhibitors are described in Falasca et al, J. Med. Chem. 2016, 60, 47-65.

[0013] Recently, the class III PI3K (Vps34) specific inhibitors, SAR304 / VPS34IN1 and SAR405, have been developed. These were shown to affect late endosomal / lysosomal compartments, to inhibit autophagy and to rescue defective endosomal exocytosis in absence of the PI(3)P phosphatase MTM1 (Ketel et al, Nature, 2016, 529, 408-412).

[0014] In contrast to class I and III PI3Ks, for class II PI3Ks few specific inhibitors exist, also because of the lack of structural information. At present no specific inhibitors of PI3K-C2b have been described. Mountford et al (ACS Medicinal Chemistry Letters, 2015, 6, 3-6) and Falasca et al. J. Med. Chem. 2016, 60, 47-65) are review articles that present comments on prospects for the development of inhibitors of class II phosphoinositide 3-kinase (PI3K) signalling and class II phosphoinositide 3- kinases as potential drug targets. The chemical structures disclosed therein are distinct from those of the present invention.

[0025] None of these documents besides WO 2019 / 234237 A1 and Pemberton et al. discloses the inhibition of class II PI3K.

[0026] In light of the lack of established class II PI3K inhibitors, the present invention sought the development of class II PI3Ks inhibitors, in particular specific inhibitors of PI3K-C2b, in order to provide novel compounds useful in research and medical treatment. In light of the prior art, and considering the relevance of class II PI3Ks in multiple medical conditions, there remains a significant need in the art to provide compounds for the inhibition of class II PI3Ks.

[0438] DETAILED DESCRIPTION

[0439] The invention relates to chemical compounds useful as inhibitors of class II phosphoinositide 3- kinase (PI3K) signalling. The invention further relates to the medical use of inhibitors of class II phosphoinositide 3-kinase (PI3K) signalling in the treatment of medical conditions associated with defective and / or pathologic class II phosphoinositide 3-kinase (PI3K) signaling, such as stroke, a cardiovascular disease related to endothelial cell dysfunction, cancer, cancer metastasis, myopathy (preferably myotubular myopathy) and diabetes.

[0440] Medical Use:

[0441] According to the invention, “medical conditions associated with defective and / or pathologic class II phosphoinositide 3-kinase (PI3K) signaling” or “associated with defective and / or pathologic signaling of the beta isoform of class II phosphoinositide 3-kinase (PKI3-C2b)” relate to any medical condition, illness, disease or other medical state in which class II phosphoinositide 3- kinase (PI3K) signaling is aberrant or associated with a defect in signaling, such as reduced signaling, enhanced signaling and / or any change in signaling associated with or responsible for the cause of a medical condition.

[0442] The term “class II phosphoinositide 3-kinase (PI3K) signaling” relates to a signaling pathway as understood by a skilled person, in preferred embodiments relating to aberrations in class II phosphoinositide 3-kinase (PI3K) activity, thereby leading to disruptions in associated signaling pathways. A review of PI3K signaling is provided in Vanhaesebroeck et al (Nat. Rev. Mol. Cell Biol. 2010, 11 , 329-341).

[0443] In preferred embodiments, without limitation thereto, the “defective and / or pathologic class II phosphoinositide 3-kinase (PI3K) signaling” or relates to elevated activity, gene copy number, or expression of class II phosphoinositide 3-kinases. In preferred embodiment, without limitation, the “defective and / or pathologic signaling of the beta isoform of class II phosphoinositide 3-kinase (PKI3-C2b)” relates to elevated activity, gene copy number, or expression of the beta isoform of class II phosphoinositide 3-kinases. Established tests are available for a skilled person to determine whether class II PI3K signaling is disrupted, for example by obtaining pathologic cells, such as cancer cells, and assessing these for said signaling, or directly assessing elevated activity, gene copy number, or expression of class II phosphoinositide 3-kinases in tumor or other biological samples, depending on the disease to be tested.

[0444] PIK3-C2b also termed “PI3KC2P” is an isoform of class PIK3 and plays a role in in signaling pathways involved in cell proliferation, oncogenic transformation, cell survival, cell migration, and intracellular protein trafficking. PIK3-C2b is associated with endocytosis, proliferation and glucose metabolism and further regulates nutrient signaling by suppressing mTORCI signaling via local production of PI(3,4)P2 at late endosomes or lysosomes (Marat et al, Science, 2017, 356, 968- 972). Based on data accumulated to this point in time, class II PI3Ks such as PIK3-C2b appear to be involved in cancer, cardiovascular disease, and diabetes, amongst other diseases (Falasca et al, J. Med. Chem. 2016, 60, 47-65).

[0445] Diabetes:

[0446] A number of PIK3-C2b deficient mouse models have been developed to date. Thereby, a mouse model in which there is combined deficiency of both PI3K-C2a and PI3K-C2b has been described, and suggests that at least some of the key functions of these two highly related enzymes do not overlap (Fyffe et al., Curr. Pharm. Des., 2013, 19, 680-686). The first significant phenotype observed in PI3KC2P- deficient mice points to a role for PI3KC2P in insulin sensitivity and glucose tolerance. Furthermore, PI3KC2PD1212A / D1212A mice were protected from high- fat diet-induced steatosis, indicating that this regulatory role of insulin signalling is particularly important in the liver (Alliouachene et al., Cell Rep., 2015, 13, 1881-1894). These results suggest that PI3K-C2b may be a potential drug target for the treatment of type 2 diabetes, as well as other insulin-resistant conditions such as nonalcoholic fatty liver diseases.

[0447] Cancer:

[0448] Thorpe et al, (Nat. Rev. Cancer, 2015, 15, 7-24) provides an extensive review of potential cancer targets in PI3K signaling.

[0449] Amplification of the gene encoding PI3K-C2b, PIK3C2B, has been reported in several tumors, such as glioblastoma multiforme and glioblastoma histological sections, and in 90 ovarian cancer specimens pointed to a similar, significant increase in PIK3C2B copy number in these cells. The observed increase in PI3K-C2b expression in ovarian cancer cells was significantly higher than of other PI3K classes. Amplification of PIK3C2B, together with MDM4, was also detected in oligodendroglia tumors. Overexpression of PI3K-C2b has been observed in different cancer cell lines and specimens, such as acute myeloid leukemia, medulloblastoma, glioblastoma multiforme. PIK3C2B was identified as one of the genes mutated in non-small-cell lung cancer samples, compared to nontumorigenic tissues. Overexpression of negative PI3K-C2b considerably inhibited growth and growth factor-induced Akt activation in small cell lung cancer. Increased expression of PI3K-C2b was also demonstrated in myeloid leukemia and acute lymphocytic leukemia. Its inhibition showed high antiproliferative activity, especially in AML cell lines, in which reduced proliferation, as well as considerable increase in apoptosis, was observed.

[0450] Taken together, these observations suggest that PI3K-C2b inhibition has value as a therapeutic strategy for the treatment of cancer, including solid tumors, with PI3K-C2b as a drug target for reducing pathologic tumor metastasis, angiogenesis and growth / survival.

[0451] In a preferred embodiment the present invention relates to cancer and / or cancer metastasis as a disease to be treated.

[0460] Myopathy: The term “myopathy” refers to a class of diseases that involve structural changes and / or functional impairments of the muscles and that are associated with defective and / or pathologic phosphoinositide 3-kinase (PI3K) signaling. Preferably the term “myopathy” refers to a mytotubular myopathy, more preferably an X-linked centronuclear myopathy.

[0461] It has been demonstrated that PIK3-C2b inhibition improves function and prolongs survival in myotubular myopathy animal models (Sabha et al, J Clin Invest. 2016,126, 3613-3625). Myotubular myopathy (MTM) is a pediatric neuromuscular disorder of phosphoinositide (PIP) metabolism resulting from mutations of the PIP phosphatase MTM1 for which there are presently no established treatments. Class II and III PI3 kinases were targeted (PI3Ks) in an MTM1- deficient mouse model. Muscle-specific ablation of Pik3c2b, but not Pik3c3, resulted in complete prevention of the MTM phenotype, and postsymptomatic targeting promoted a striking rescue of disease. The PI3K inhibitor wortmannin also improved motor function and prolonged lifespan of the Mtm1 -deficient mice. This evidence speaks strongly for a therapeutic effect of PIK3 inhibitors in treating myopathy. Muscular dystrophies such as

[0501] Compositions and modes of treatment:

[0502] The present invention relates further to pharmaceutically acceptable salts of the compounds described herein. The term "pharmaceutically acceptable salt" refers to salts or esters of the compounds described herein prepared by conventional means that include basic salts of inorganic and organic acids. "Pharmaceutically acceptable salts" are also inclusive of the free acid, base, and zwitterionic forms. Descriptions of suitable pharmaceutically acceptable salts can be found in Handbook of Pharmaceutical Salts, Properties, Selection and Use, Wiley VCH (2002). For therapeutic use, salts of the compounds are those wherein the counter-ion is pharmaceutically acceptable. However, salts of acids and bases which are non-pharmaceutically acceptable may also find use, for example, in the preparation or purification of a pharmaceutically acceptable compound.

[0503] Another aspect of the disclosure includes pharmaceutical compositions prepared for administration to a subject and which include a therapeutically effective amount of one or more of the compounds disclosed herein. In certain embodiments, the pharmaceutical compositions are useful for treating medical conditions associated with defective and / or pathologic class II phosphoinositide 3-kinase (PI3K) signaling, preferably defective and / or pathologic signaling of the beta isoform of class II phosphoinositide 3-kinase (PIK3-C2b), such as myopathy, cancer, diabetes and cardiovascular disease.

[0504] The therapeutically effective amount of a disclosed compound will depend on the route of administration, the species of subject and the physical characteristics of the subject being treated. Specific factors that can be taken into account include disease severity and stage, weight, diet and concurrent medications. The relationship of these factors to determining a therapeutically effective amount of the disclosed compounds is understood by those of skill in the art. Pharmaceutical compositions for administration to a subject can include at least one further pharmaceutically acceptable additive such as carriers, thickeners, diluents, buffers, preservatives, surface active agents and the like in addition to the molecule of choice. Pharmaceutical compositions can also include one or more additional active ingredients such as antimicrobial agents, anti-inflammatory agents, anesthetics, and the like. The pharmaceutically acceptable carriers useful for these formulations are conventional. Remington's Pharmaceutical Sciences, by E. W. Martin, Mack Publishing Co., Easton, PA, 19th Edition (1995), describes compositions and formulations suitable for pharmaceutical delivery of the compounds herein disclosed.

[0505] In general, the nature of the carrier will depend on the particular mode of administration being employed. For instance, parenteral formulations usually contain injectable fluids that include pharmaceutically and physiologically acceptable fluids such as water, physiological saline, balanced salt solutions, aqueous dextrose, glycerol or the like as a vehicle. For solid compositions (for example, powder, pill, tablet, or capsule forms), conventional non-toxic solid carriers can include, for example, pharmaceutical grades of mannitol, lactose, starch, or magnesium stearate. In addition to biologically-neutral carriers, pharmaceutical compositions to be administered can contain minor amounts of non-toxic auxiliary substances, such as wetting or emulsifying agents, preservatives, and pH buffering agents and the like, for example sodium acetate or sorbitan monolaurate.

[0506] The pharmaceutical compositions can be administered to subjects by a variety of mucosal administration modes, including by oral, rectal, intraocular, intranasal, intrapulmonary, or transdermal delivery, or by topical delivery to other surfaces. Optionally, the compositions can be administered by non-mucosal routes, including by intramuscular, intraocular, subcutaneous, intravenous, intra-arterial, intra-articular, intraperitoneal, intrathecal, intracerebroventricular, or parenteral routes.

[0507] The compositions of the disclosure can alternatively contain as pharmaceutically acceptable carrier substances as required to approximate physiological conditions, such as pH adjusting and buffering agents, tonicity adjusting agents, wetting agents and the like, for example, sodium acetate, sodium lactate, sodium chloride, potassium chloride, calcium chloride, sorbitan monolaurate, and triethanolamine oleate. For solid compositions, conventional nontoxic pharmaceutically acceptable vehicles can be used which include, for example, pharmaceutical grades of mannitol, lactose, starch, magnesium stearate, sodium saccharin, talcum, cellulose, glucose, sucrose, magnesium carbonate, and the like.

[0508] In a preferred embodiment the invention comprise the topical and / or local administration of a compound as described herein and / or a composition comprising a compound as described herein to a subject. The term “topical administration” refers to the delivery of a pharmacologically active agent to the skin or mucosa of a patient. Topical administration can provide a local rather than a systemic effect. The terms “topical administration” and “transdermal administration” are used interchangeably to mean administration of a pharmacologically active agent to the skin or mucosa of a patient to achieve a therapeutic effect in treating or preventing a medical disorder of the invention or discomfort at the site of topical or transdermal administration. Preferred administration modes relate to a topical solution, lotion, shake lotion, cream, ointment, gel, foam, transdermal patch, powder, solid form, sponge, tape, paste or tincture. Preferred embodiments relate to creams, foams, gels, lotions, and ointments.

[0509] Various additives, known to those skilled in the art, may be included in topical compositions of the present disclosure. For example, solvents, including relatively small amounts of alcohol, may be used to solubilize a compound of the invention. Other optional additives include antioxidants, fragrances, colorant, gelling agents, emulsifiers, thickening agents, stabilizers, surfactants, buffers, cooling agents (e.g., menthol) and the like. Other agents may also be added, such as antimicrobial agents, to prevent spoilage upon storage, i.e., to inhibit growth of microbes such as yeasts and molds. Examples of suitable antimicrobial agents include methyl and propyl esters of p-hydroxybenzoic acid (i.e., methyl and propyl paraben), sodium benzoate, sorbic acid, imidurea, and the like. When applied to skin, a topical composition of the present disclosure can be covered with an occlusive or non-occlusive dressing, which may be porous or non-porous, so as to protect the composition from mechanical removal during the period of treatment, e.g. a plastic film food wrap or other non-absorbent film. Various inert coverings may be employed. Non-woven or woven coverings may be employed, particularly elastomeric coverings, which allow for heat and vapor transport. These coverings can allow for cooling of the diseased site, which can provide for greater comfort, while protecting the composition from mechanical removal.

[0510] In accordance with the various treatment methods of the disclosure, the compound can be delivered to a subject in a manner consistent with conventional methodologies associated with management of the disorder for which treatment or prevention is sought. In accordance with the disclosure herein, a prophylactically or therapeutically effective amount of the compound and / or other biologically active agent is administered to a subject in need of such treatment for a time and under conditions sufficient to prevent, inhibit, and / or ameliorate a selected disease or condition or one or more symptom(s) thereof.

[0511] "Administration of' and "administering a" compound should be understood to mean providing a compound, a prodrug of a compound, or a pharmaceutical composition as described herein. The compound or composition can be administered by another person to the subject (e.g., intravenously, gel, cream, spray) or it can be self-administered by the subject (e.g., tablets, gel, cream, spray).

[0512] Dosage can be varied by the attending clinician to maintain a desired concentration at a target site (for example, the lungs or systemic circulation). Higher or lower concentrations can be selected based on the mode of delivery, for example, trans-epidermal, rectal, oral, pulmonary, or intranasal delivery versus intravenous or subcutaneous delivery. Dosage can also be adjusted based on the release rate of the administered formulation, for example, of an intrapulmonary spray versus powder, sustained release oral versus injected particulate or transdermal delivery formulations, and so forth.

[0513] The term "subject" includes both human and veterinary subjects. The term "treatment" refers to a therapeutic intervention that ameliorates a sign or symptom of a disease or pathological condition after it has begun to develop.

[0514] As used herein, the term "ameliorating", with reference to a disease or pathological condition, refers to any given beneficial effect of the treatment. The beneficial effect can be evidenced, for example, by a delayed onset of clinical symptoms of the disease in a subject, a reduction in severity of some or all clinical symptoms of the disease, a slower progression of the disease, an improvement in the overall health or well-being of the subject, or by other parameters well known in the art that are specific to the particular disease.

[0515] The present invention encompasses both therapeutic treatment and prophylactic treatment of a subject. A "prophylactic" treatment is a treatment administered to a subject, who does not exhibit signs of the medical condition or who preferably exhibits indications of developing or developing further any given medical condition, for the purpose of decreasing the risk of developing pathology or clinical symptoms. A prophylactic administration may comprise the administration of the compounds in advance of developing symptoms, thereby avoiding or reducing the subsequent occurrence of a disease. The present invention also relates to a method of treatment of subjects suffering from the various medical conditions disclosed herein. The method of treatment comprises preferably the administration of a therapeutically effective amount of a compound disclosed herein to a subject in need thereof.

[0516] A "therapeutically effective amount" refers to a quantity of a specified agent sufficient to achieve a desired effect in a subject being treated with that agent. For example, this may be the amount of a compound disclosed herein useful in alleviating the symptoms of one or more of the medical conditions described herein in a subject. The therapeutically effective amount or diagnostically effective amount of an agent will be dependent on the subject being treated, the severity of illness, and the manner of administration of the therapeutic composition. Dosage regimens can be adjusted to provide an optimum prophylactic or therapeutic response. A therapeutically effective amount is also one in which any toxic or detrimental side effects of the compound and / or other biologically active agent is outweighed in clinical terms by therapeutically beneficial effects. A non-limiting range for a therapeutically effective amount of a compound and / or other biologically active agent within the methods and formulations of the disclosure is about 0.001 mg / kg body weight to 50 mg / kg body weight, 0.01 mg / kg body weight to about 20 mg / kg body weight, such as about 0.05 mg kg to about 5 mg / kg body weight, or about 0.2 mg / kg to about 2 mg / kg body weight.

[0517] The instant disclosure also includes kits, packages and multi-container units containing the herein described pharmaceutical compositions, active ingredients, and / or means for administering the same for use in the prevention and treatment of diseases and other conditions in mammalian subjects.

[0533] The invention is further described by the following examples. These are not intended to limit the scope of the invention but represent preferred embodiments of aspects of the invention provided for greater illustration of the invention described herein.

[0534] Example 1 : Inhibitor development and structural characterization of PI3KC2p.

[0535] Functional genetic data indicate that PI3KC2P is a potential drug target forX-linked myotubular myopathy (XLMTM) treatment. So far, the structure of PI3KC2P is still unresolved. Besides, no potent and selective inhibitors against PI3KC2P have been described. The object of this invention is therefore the development of novel small molecular inhibitor for structurally unveiling the pharmacological target sites in PI3KC2P and for XLMTM treatment.

[0536] Example 2: Expression and purification of PI3KC2pANKKT

[0537] To overcome limitations with respect to the availability of pure recombinant PI3KC2P and the poor activity of PI3KC2P against PI as substrate. The inventors engineer the human PI3KC2P with truncation of AA 1-297 and mutation of1248DPK1250to1248^1-1250 according to previous experiences on the purification PI3KC2o. The PI3KC2PANKKT was tagged with 10x histidine at its N-termini. The expression of PI3KC2PANKKT was performed by baculovirus-infected insect cells. The cells were grown to a cell density at 1 .5 million cells / ml and infected with 1 :50 (volume ratio) of virus stock. The expression of PI3KC2pANKKT takes place for 48-hours post infection. PI3KC2PANKKT was purified with Ni-NTA beads and followed by size exclusion chromatography. The peak fractions containing PI3KC2PANKKT were validated by SDS-PAGE and Coomassie blue staining. Purified PI3KC2PANKKT was concentrated to a protein concentration at 0.4 mg / ml. The sample was snap frozen by liquid nitrogen and stored at -80 °C freezer.

[0538] Example 3: Enzymatic activity and assay development for purified PI3KC2pANKKT

[0539] The kinase activity of purified PI3KC2ANKKT was measured by ADP-Glo™ kinase assay. To determine the linear correlation rage of the signal with different amount of kinase, the kinase activity was first measured with titrated concentration of PI3KC2PANKKT and fixed concentration of PI (200 pM) and ATP (100 pM). The activity curve displays a broad range of linear correlation in the setup. To measure the Km of ATP for PI3KC2PANKKT, the activity of 10 ng / pl purified kinase together with 200 pM of PI and titrated concentration of ATP were used for triplicated measurement. The titration curve was fit into Michaelis-Menten equation to obtain the Km value of ATP for PI3KC2ANKKT is 63.7 pM. Therefore, the IC50 measurements for chemical compounds were established with 10 ng / pl purified PI3KC2PANKKT, PI (200 pM), and ATP (40 pM).

[0540] Example 4: Cellular activity of chemical compounds

[0541] Four PI3KC2P inhibitors (DC-03-036, -040, -090, -096) were selected for cellular activity measurement. Because PI3KC2P kinase activity is the negative regulator of mTOR1 activity on phosphorylation of S6K, the cellular activity of PI3KC2P can be reported by pS6K level. PKN2 is the known negative regulator for basal PI3KC2P activity. Therefore, the protocol for cellular treatment was established with overnight incubation of compounds with HEK cell at 1 pM concentration and followed by 2-hours PKN1 / 2 inhibition. With DC-03-036, -040, -090, -096 treatment, pS6K level showed significant increase indicating DC-03-036, -040, -090, -096 can inhibit PI3KC2P activity in the cell.

[0542] Example 4: Kinase selectivity of chemical compounds

[0543] Five PI3KC2P inhibitors (example compounds 2, 18, 19, 47 and 91) were selected for the measurement of kinase selectivity in an extended panel. The results for the respective compounds are shown in tables 2 to 6.

[0544] SelectScreen Kinase Profiling was performed at ThermoFisher Scientific (Table 2-6) following protocols described by Kashem et al. J. Biomol. Screen. 2007, 12, 70-83 (Adapta); Lebakken et al. J. Biomol. Screen. 2009, 14; 924-935 (lanthascreen); Kleman-Leyer et al. Drug Disc. Devel. 2003, 6, 81-82. (zlyte)

[0545] Kinobead profiling was performed by adapting procedures described by Reinecke et al. ACS Chem. Biol. 2019, 14, 655-664 and Klaeger et al., Science 2017, 358, eaan4368

[0546] Kinobead pulldown assays were performed using 5 mg / mL HEK293 cell lysates in IGEPAL CA- 630-containing buffer 32. Briefly, for profiling each compound, 12 wells of a 96-well plate were filled with lysate (2.5 mg of total proteins per well) and incubated for 45 min at 4 °C in an end- over-end shaker with 0 nM (DMSO control), 30 nM, 100 nM, 300 nM, 1 pM, 3 pM, 10 pM, 30 pM, 100 pM, 300 pM and 1 mM of compound dissolved in DMSO. Subsequently, the treated lysates were incubated with Kinobeads-E for 30 min at 4 °C in a 96-well filter plate on an end-over-end shaker. The beads were then washed before the bound proteins were denatured and alkylated with chloroacetamide. Addition of trypsin (300 ng per well) started overnight on-bead digestion. Acidified peptide eluates were then subjected to C18 StageTip desalting for LC-MS / MS analysis on an Orbitrap Fusion Lumos Tribrid (ThermoFisher Scientific) mass spectrometer coupled to an online Dionex Ultimate3000 equipped with a micro flow Vanquish pump UHPLC (ThermoFisherScientific). MaxQuant (v.1.5.3.30.) / Andromeda was used to quantify proteins using the Swissprot reference database containing all canonical protein sequences with standard settings. Dose-response curves, Kdapps and the kinome tree were derived from the proteinGroup.txt file using a set of R scripts.

[0557] Km app MKNK1 (MNK1) 7 The evaluation on kinase selectivity (Tables 2 to 6) and inhibitory concentration (IC50) (Table 1) shows that the compounds of the present invention show a selectivity for the PIK3C2 kinases, having a substantially lower IC50 for the inhibition of PI3K-C2b (PI3KC2P) compared to PI3Ky (see for in table 1 for example compound 2: PI3KC2P IC50 [nM] = 18 and PI3Ky IC50 [nM] = 1024; compound 18: PI3KC2 IC50 [nM] = 42 and PI3Ky IC50 [nM] = > 5000; compound 19: PI3KC2P IC50 [nM] = 22 and PI3Ky IC50 [nM] = 3570; compound 47: PI3KC2 IC50 [nM] = 56 and PI3Ky IC50 [nM] = > 10000 and compound 91 : PI3KC2 IC50 [nM] = 48 and PI3Ky IC50 [nM] = > 10000) The compounds of the present invention are thus particularly effective for inhibiting PIK3C2 kinases, in particular PI3K-C2b.

[0558] The compounds were further screened by a kinobead pulldown assay performed on HEK293 cell lysates at ten different concentrations. Hit criteria were an IC50 < 10 pM. The results are shown in Figure 5. For example compounds 47 and 91 no hit except the desired target PI3KC2b was found. This further confirms that the compounds of the present invention are particularly effective for inhibiting PIK3C2 kinases, in particular PI3K-C2b.

[0559] Methods employed for protein expression and ADP-Glo kinase assay:

[0560] Protein purification

[0561] His -tagged PI3KC2PANKKT was expressed in Sf21 insect cells, using SF900-II serum-free media (ThermoFisher). S / 21 cells (800 ml) grown to a density of 1 .5-2 x 106cells / ml were infected with 16 ml amplified baculovirus encoding the desired construct. Cells were harvested at 48h post-infection. Cell pellets were frozen and stored at -20 °C until purification. For purification, cell pellets from each 200 ml culture were resuspended in 30 ml lysis buffer (50 mM Tris pH 7.2, 300 mM NaCI, 10 mM imidazole, 1 mM DTT, 0.5% Triton X-100, 1 tablet / 50ml protease inhibitor cocktail), sonicated for 1 min (1s pulse on, 5 s pulse off) and centrifuged for 20 min at 27k rpm 50 ml supernatant were incubated with 0.25 ml Nickel NTA beads (Sigma Inc.) on a rotating wheel for 1 h. Beads were collected in an open column, washed with 10 ml lysis buffer, then 3 times with 10 ml wash buffer (50 mM Tris pH 7.5, 300 mM NaCI, 20 mM imidazole, 1 mM DTT). Protein was eluted with 8 ml elution buffer (20 mM Tris pH 7.5, 300 mM NaCI, 300 mM imidazole, 5 mM DTT). PI3KC2PANKKT was immediately further purified by a Superdex 200 gel filtration column at 4°C with SEC buffer (20 mM Tris pH 7.5, 300 mM NaCI, 5 mM DTT). PI3KC2PANKKT were concentrated to 0.4 mg / ml. The sample were flash frozen in liquid nitrogen and stored at -80°C.

[0562] ADP-Glo kinase assay

To do the kinase titration, the kinase reaction was initiated by adding titrated amount of purified PI3KC2PANKKT. For measurement of Km of ATP, the titrated amount of ATP in PI solution was prepared. Reactions were started by mixing 5 pl of protein stock with 5 pl of substrate solution and incubated for 20 m at room temperature. The reactions were stopped by adding 10 pl of ADP-Glo reagent (Promega). After 40 min incubation, 20 pl Kinase Detection Reagent were added. After 20 min incubation, luminescence was read with a TECAN plate reader. IC50 measurements of chemical compound were carried out using concentration series of compounds, and 10 ng / pl PI3KC2pANKKT, 200 pM PI, and 40 pM ATP.

[0564] Cell treatment and Western blot

[0565] 0.4 million HEK cells per well were seeded to poly-Lys coated 6-wells plate. 10- hours after seeding, DSMO or chemical compounds were applied to the cell af final concentration of 0.1 % DMSO or 1 pM in respect. After overnight treatment, cells were treated with PKN1 / 2 inhibitor cocktail for 2-hours. To collect the cell lysate, cells were washed three times in ice-cold PBS and collected in TBS with 1% CHAPS, 1 tablet / 10ml of protease inhibitor cocktail mini (Roch) and phosphatase inhibitors (cocktails 2 and 3, Sigma-Aldrich). Protein levels were quantified using Bradford reagent (Sigma-Aldrich). Equal concentration lysates in Laemmli sample buffer were boiled for 5 min; between 10 and 30 pg protein was resolved by SDS-PAGE and analysed via immunoblot using LI-COR 800CW infrared secondary antibodies.
