Definitions
- the general field of the present disclosure are novel approaches to the treatment of Alzheimer’s and other neurodegenerative disorders using novel therapeutics comprising SHIP1 phosphatase inhibitors.
- AD Alzheimer’s disease
- AP extracellular P-amyloid
- NFTs intra-neuronal neurofibrillary tangles
- amyloid cascade hypothesis has come under increased scrutiny due to inadequate efficacy of drugs targeting Ap peptide processing and various forms of Ap. See Panza et al., “A critical appraisal of amyloid-beta-targeting therapies for Alzheimer disease,” (2019) Nat Rev Neurol 15: pp. 73-88.
- GWAS genome-wide association studies
- whole genome sequencing differential gene expression
- gene-expression network analyses comparing normal to affected Alzheimer’s brain tissue have identified risk and protective variants in genes such as TREM2, CD33, APOE, ABCA7, PLCG2, and INPP5D, which are essential to microglia function.
- genes such as TREM2, CD33, APOE, ABCA7, PLCG2, and INPP5D, which are essential to microglia function.
- Microglia are the non-neuronal, macrophage-like cells that serve as resident immune cells in the brain.
- Vaughan et al. “Neuroglial cells in the cerebral cortex of rats from young adulthood to old age: an electron microscope study,” (1974) J Neurocytol 3: pp. 405-429.
- microglia originate from stem cells in the yolk sac and differentiate into CD45 + , CX3CR1 + immune cells that migrate to the central nervous system (CNS).
- CNS central nervous system
- AD Disease associated microglia
- TREM2 ligands such as apolipoproteins (including, e.g., APOE) and Ap induce microglial differentiation into stage-2 DAMs with increased expression of LP1, CST7, and AXE Deczkowska et al., “Disease-Associated Microglia: A Universal Immune Sensor of Neurodegeneration,” (2016) Cell 173: pp. 1073-1081; Keren-Shaul et al. 2017.
- TREM2 is a receptor expressed on the surface of microglia. Genetic evidence suggests that lower TREM2 expression and inactivating variants increase risk of AD. See Jonsson et al., Variant of TREM2 associated with the risk of Alzheimer's disease N Engl J Med 368: pp. 107 116. TREM2 extracellular debris. See Yeh TREM2 Binds to Apolipoproteins, Including APOE and CLU/APOJ, and Thereby Facilitates Uptake of Amyloid-Beta by Microglia Neuron 91: pp. 328 340.
- the TREM2 R47H variant reduces the affinity of TREM2 ligands and cellular activation downstream, which requires DAP12, an adapter protein on the intracellular side of the plasma membrane that associates with numerous signal transduction mediators.
- DAP12 an adapter protein on the intracellular side of the plasma membrane that associates with numerous signal transduction mediators.
- DAP12 an adapter protein on the intracellular side of the plasma membrane that associates with numerous signal transduction mediators.
- an activating variant of PLCG2, PLCG2 P522R is protective in AD.
- PLCG2 P522R Alzheimer's disease phospholipase C-gamma-2
- This human genetic evidence suggests that dampened microglia activity increases risk and mitigating an inflammatory microenvironment that is toxic to neurons.
- the recent regulatory approval of the anti-amyloid antibody aducanumab provides evidence for the role of activated microglia in the treatment of AD. See Aducanumab for Alzheimer Disease- JAMA Intern Med 181: pp. 1276 1278. antibodies triggering downstream effector functions.
- the INPP5D gene encodes the Src homology 2 (SH2) domain containing phosphatase- 1 (SHIP1), which is a phosphatidylinositol phosphatase that plays a key role regulating pathways downstream from TREM2.
- SH2 Src homology 2
- SHIP1 phosphatase- 1
- SHIP1 is a complex, multi-domain protein with a phosphatase (Ptase) domain flanked by a pleckstrin-homology (PH) domain that binds phosphatidylinositol (3,4,5)-trisphosphate [PI(3,4,5)P3] and a C2 domain that binds phosphatidylinositol (3,4)-bisphosphate [PI(3,4)P2].
- Ptase phosphatase
- PH pleckstrin-homology
- the C2 domain is essential for cellular function and interactions between the Ptase and C2 domains modulate enzymatic activity. See Le Coq et al., “Structural basis for interdomain communication in SHIP2 providing high phosphatase activity,” (2017) eLife 6: p. 26640.
- SHIP1 converts PI(3,4,5)P?, to PI(3,4)P2.
- SHIP1 also contains an N-terminal SH2 domain that binds immunoreceptor tyrosine-based activation motifs (ITAMs) and a C-terminal proline rich domain that binds many other proteins including PLCy2 and the Tec and Syk family kinases.
- ITAMs immunoreceptor tyrosine-based activation motifs
- PI(3,4,5)P3 binds and activates other PH-containing proteins such as PLCy2, PDK1, and AKT.
- PLCy2, PDK1, and AKT PH-containing proteins
- SH1P1 binds ITAMs, competes with kinases, and converts Pl(3,4,5)Ps to PI(3,4)P2, it limits downstream signaling in multiple ways, and is therefore understood as a brake on microglia activation.
- the present disclosure provides novel compounds that are SHIP 1 inhibitors that address the need for a potent and effective treatment for Alzheimer’s disease and Alzheimer’s disease- related dementias.
- the present disclosure also provides a pharmaceutical composition for the prevention of Alzheimer’s disease and Alzheimer’s disease-related dementias.
- the present inventors have performed a screen of about 50,000 compounds at the SHIP1 phosphatase, analyzed a publicly available fragment-based screen, and evaluated inhibitors reported in the literature. They utilized the malachite green assay with PtdIns(3,4,5)P3-diCs and SHIP1 Ptase-C2 to measure inhibitory potency. A Cellular Thermal Shift Assay was used to confirm target engagement in cells. A high-content imaging assay measuring phagocytosis, cell number, and nuclear intensity was implemented using the BV2 and HMC3 cell lines to characterize cellular pharmacology and cytotoxicity. Mouse microglia were assayed to demonstrate similar activity in primary cells.
- Inhibitors predicted to have drug-like properties were subjected to assays measuring solubility, cellular permeability, and mouse microsomal stability. A physiological based pharmacokinetic model was compared to measured exposure in vivo for select compounds upon oral administration in mice.
- Inhibition of SHIP1 is a novel therapeutic strategy for treatment of Alzheimer’s. Identified were structurally distinct molecular scaffolds with varying degrees of enzyme inhibition, cellular activity, and exposure in mice.

[0007] FIELD
[0008] The general field of the present disclosure are novel approaches to the treatment of Alzheimer’s and other neurodegenerative disorders using novel therapeutics comprising SHIP1 phosphatase inhibitors.
[0009] BACKGROUND
[0010] Alzheimer’s disease (AD) is a fatal, neurodegenerative disorder, characterized by histopathological accumulation of extracellular P-amyloid (AP) plaques and intra-neuronal neurofibrillary tangles (NFTs), which have been hypothesized to result in neurotoxicity and progressive cognitive decline. See Kumar et al., “A review on Alzheimer's disease pathophysiology and its management: an update, (2015) Pharmacol Rep 67: pp. 195-203; Hardy et al., “Alzheimer's disease: the amyloid cascade hypothesis: an update and reappraisal,” (2006) J Alzheimers Dis 9: pp. 151-153; Shen et al, “Complement activation by neurofibrillary tangles in Alzheimer's disease,” (2001) Neurosci Lett 305: pp. 165—168; Scheltens et al., “Alzheimer's disease, 2Q2\)Lancet 397: pp. 1577-1590. The amyloid cascade hypothesis postulates that various forms of Ap oligomers and plaques are instrumental in a neuropathological process that triggers subsequent NFT pathology, neuroinflammation, and neuronal loss; however, the mechanisms by which AP influences neurotoxic signaling including NFT formation remain an area of intense
study. Recently, the amyloid cascade hypothesis has come under increased scrutiny due to inadequate efficacy of drugs targeting Ap peptide processing and various forms of Ap. See Panza et al., “A critical appraisal of amyloid-beta-targeting therapies for Alzheimer disease,” (2019) Nat Rev Neurol 15: pp. 73-88.
[0011] More recent evidence including genome-wide association studies (GWAS), whole genome sequencing, differential gene expression, and gene-expression network analyses comparing normal to affected Alzheimer’s brain tissue have identified risk and protective variants in genes such as TREM2, CD33, APOE, ABCA7, PLCG2, and INPP5D, which are essential to microglia function. See Malik et al., “Genetics ignite focus on microglial inflammation in Alzheimer's disease,” (2015) Mol Neurodegener 10: p. 52. Microglia are the non-neuronal, macrophage-like cells that serve as resident immune cells in the brain. See Vaughan et al., “Neuroglial cells in the cerebral cortex of rats from young adulthood to old age: an electron microscope study,” (1974) J Neurocytol 3: pp. 405-429.
[0012] During development microglia originate from stem cells in the yolk sac and differentiate into CD45+, CX3CR1+ immune cells that migrate to the central nervous system (CNS). See Kierdorf et al., “Microglia emerge from erythromyeloid precursors via Pu. 1 - and Independent pathways,” (2013) Nat Neurosci 16: pp. 273-280. Once resident, these cells renew slowly in humans at a rate of approximately 28 percent per year, thus providing a mechanism to renew microglia. See Reu et al., “The Lifespan and Turnover of Microglia in the Human Brain,” (2017) Cell Rep 20: pp. 779-784. Disease associated microglia (DAM) have been characterized at sites of Ap plaques and neurodegeneration in animal models. See Keren-Shaul et al., “A Unique Microglia Type Associated with Restncting Development of Alzheimer's Disease,” (2017) Cell 169: pp. 1276-1290. Although their relevance to human microglia in AD remains a current area of intense study, they have gene signatures associated with lipid metabolism and phagocytosis hypothesized to reflect the neuroprotective role of microglia in the clearance of extracellular toxins. See Olah et al., “Single cell RNA sequencing of human microglia uncovers a subset associated with Alzheimer's disease,” (2020) Nat Commun 11: pp. 6129. A two-state model of DAM induction has been proposed, in which homeostatic microglia that are associated with and support the health of neurons become activated with increased expression oiDAP12, APOE, and Triggering receptor expressed on myeloid cells-2 (TREM2). TREM2 ligands such as apolipoproteins (including, e.g., APOE) and Ap induce microglial differentiation into stage-2 DAMs with increased expression of LP1, CST7, and AXE Deczkowska et al., “Disease-Associated Microglia: A Universal Immune Sensor of Neurodegeneration,” (2018) Cell 173: pp. 1073-1081; Keren-Shaul et al. 2017.
[0013] TREM2 is a receptor expressed on the surface of microglia. Genetic evidence suggests that lower TREM2 expression and inactivating variants increase risk of AD. See Jonsson et al., Variant of TREM2 associated with the risk of Alzheimer's disease N Engl J Med 368: pp. 107 116. TREM2 extracellular debris. See Yeh TREM2 Binds to Apolipoproteins, Including APOE and CLU/APOJ, and Thereby Facilitates Uptake of Amyloid-Beta by Microglia Neuron 91: pp. 328 340. The TREM2R47H variant reduces the affinity of TREM2 ligands and cellular activation downstream, which requires DAP12, an adapter protein on the intracellular side of the plasma membrane that associates with numerous signal transduction mediators. See Sudom et al., Molecular basis for the loss-of-function effects of the Alzheimer's disease-associated R47H variant of the immune receptor TREM2 J Biol Chem 293: pp.12634 12646. For example, recruitment of SYK to phosphorylated tyrosine residues at the C-terminus of DAP12 mediates 3 and Ca2+ release. See -Edged Sword in Neural Diseases Front Cell Neurosci 12: p.206. Importantly, an activating variant of PLCG2, PLCG2P522R is protective in AD. See Magno et al. Alzheimer's disease phospholipase C-gamma-2 (PLCG2) protective variant is a functional hypermorph Res Ther 11: p. 16. This human genetic evidence suggests that dampened microglia activity increases risk and mitigating an inflammatory microenvironment that is toxic to neurons. See Deczkowska et al., 2018. [0014] The recent regulatory approval of the anti-amyloid antibody aducanumab provides evidence for the role of activated microglia in the treatment of AD. See Aducanumab for Alzheimer Disease- JAMA Intern Med 181: pp. 1276 1278. antibodies triggering downstream effector functions. See Bournazos The role of IgG Fc receptors in antibody-dependent enhancement Nat Rev Immunol 20: pp. 633 643. The a -mediated enhancement of microglia recruitment and phagocytosis. See Sevigny et al The antibody aducanumab reduces Abeta plaques in Alzheimer's disease Nature 537: pp.50 56. [0015] The INPP5D gene encodes the Src homology 2 (SH2) domain containing phosphatase- 1 (SHIP1), which is a phosphatidylinositol phosphatase that plays a key role regulating pathways
downstream from TREM2. See Peng et al., “TREM2- and DAP12-dependent activation of PI3K requires DAP10 and is inhibited by SHIP1,” (2010) Sci Signal 3: p. 38; Pauls et al., “Regulation of immune cell signaling by SHIP1 : A phosphatase, scaffold protein, and potential therapeutic target,” (2017) Eur J Immunol 47: pp. 932-945. SHIP1 is a complex, multi-domain protein with a phosphatase (Ptase) domain flanked by a pleckstrin-homology (PH) domain that binds phosphatidylinositol (3,4,5)-trisphosphate [PI(3,4,5)P3] and a C2 domain that binds phosphatidylinositol (3,4)-bisphosphate [PI(3,4)P2]. See Damen et al., “The 145-kDa protein induced to associate with She by multiple cytokines is an inositol tetraphosphate and phosphatidylinositol 3,4,5-triphosphate 5-phosphatase,” (1996) Proc Natl Acad Sci USA 93: pp. 1689-1693; Blunt et al., “Pharmacological targeting of phosphoinositide lipid kinases and phosphatases in the immune system: success, disappointment, and new opportunities,” (2012) Front Immunol 3: p. 226. The PH and C2 domains locate and orient the catalytic site towards its PI(3,4,5)Ps substrate at the intracellular side of the membrane. The C2 domain is essential for cellular function and interactions between the Ptase and C2 domains modulate enzymatic activity. See Le Coq et al., “Structural basis for interdomain communication in SHIP2 providing high phosphatase activity,” (2017) eLife 6: p. 26640. SHIP1 converts PI(3,4,5)P?, to PI(3,4)P2. SHIP1 also contains an N-terminal SH2 domain that binds immunoreceptor tyrosine-based activation motifs (ITAMs) and a C-terminal proline rich domain that binds many other proteins including PLCy2 and the Tec and Syk family kinases. PI(3,4,5)P3 binds and activates other PH-containing proteins such as PLCy2, PDK1, and AKT. See Scheffzek et al., “Pleckstrin homology (PH) like domains — versatile modules in protein-protein interaction platforms,” (2012) FEBS Lett 586: pp. 2662-2673. Because SH1P1 binds ITAMs, competes with kinases, and converts Pl(3,4,5)Ps to PI(3,4)P2, it limits downstream signaling in multiple ways, and is therefore understood as a brake on microglia activation. See Pauls et al. 2017.
[0016] Taken together, this understanding of AD risk and protective variants in genes critical to the activity of microglia, the role of microglia in the clearance of A0, and SHIP1 as a limiting node downstream from TREM2 and FCyRIIB, suggests that inhibition of SHIP1 would activate microglia, and would therefore be an effective therapeutic strategy in disease. This therapeutic intervention could be synergistically combined with anti-amyloid and/or TREM2 agonist antibodies. Therefore, inhibitors of SHIP1 would increase the protective functions of microglia and could therefore be used to prevent or treat disease, reduce the rate of disease progression and cognitive decline in patients, and reverse neurodegeneration.
[0017] The present disclosure provides novel compounds that are SHIP 1 inhibitors that address the need for a potent and effective treatment for Alzheimer’s disease and Alzheimer’s disease- related dementias. The present disclosure also provides a pharmaceutical composition for the prevention of Alzheimer’s disease and Alzheimer’s disease-related dementias.
[0018] SUMMARY
[0019] Recent evidence including genome-wide association studies (GWAS), whole genome sequencing, differential gene expression, and gene-expression network analyses comparing normal to affected Alzheimer’s brain tissue have identified risk and protective variants in genes such as TREM2, PLCG2 and INPP5D that are essential to microglia function. INPP5D encodes SHIP1, a multi-domain protein with a phosphatase that converts PI(3,4,5)Pa to PI(3,4)P2, a SH2 domain that interacts with receptor ITAMs and competes with SYK. and a proline rich region that binds many other proteins. SHIP1 therefore limits microglia activation in multiple ways. Inhibition of SHIP1 early in disease would increase microglial protective functions and reduce the rate of disease progression and cognitive decline in Alzheimer’s patients.
[0020] The present inventors have performed a screen of about 50,000 compounds at the SHIP1 phosphatase, analyzed a publicly available fragment-based screen, and evaluated inhibitors reported in the literature. They utilized the malachite green assay with PtdIns(3,4,5)P3-diCs and SHIP1 Ptase-C2 to measure inhibitory potency. A Cellular Thermal Shift Assay was used to confirm target engagement in cells. A high-content imaging assay measuring phagocytosis, cell number, and nuclear intensity was implemented using the BV2 and HMC3 cell lines to characterize cellular pharmacology and cytotoxicity. Mouse microglia were assayed to demonstrate similar activity in primary cells. Inhibitors predicted to have drug-like properties were subjected to assays measuring solubility, cellular permeability, and mouse microsomal stability. A physiological based pharmacokinetic model was compared to measured exposure in vivo for select compounds upon oral administration in mice.

[0036] DETAILED DESCRIPTION
[0037] Various quantities, such as amounts, sizes, dimensions, proportions, and the like, are presented in a range format throughout this disclosure. It should be understood that the description of a quantity in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of any embodiment. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as all individual numerical values within that range unless the context clearly dictates otherwise. For example, description of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6 etc., as well as individual values within that range, for example, 1.1, 2, 2.3, 4.62, 5, and 5.9. This applies regardless of the breadth of the range. The upper and lower limits of these intervening ranges may independently be included in the smaller ranges, and are also encompassed within the disclosure, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure, unless the context clearly dictates otherwise.
[0038] The terminology used herein is to describe particular embodiments only and is not intended to be limiting of any embodiment. As used herein, the singular forms “a.” “an”, and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes”, “comprises”, “including” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Additionally, it should be appreciated that items included in a list in the form of “at least one of A, B, and C” can mean (A); (B); (C); (A and B); (B and C); (A and C); or (A. B, and C). Similarly, items listed in the form of “at least one of A. B, or C” can mean (A); (B); (C); (A and B); (B and C); (A and C); or (A, B, and C).
[0039] Unless expressly stated or obvious from context, as used herein, the term “about” in reference to a number or range of numbers is understood to mean the stated number and numbers +/- 10% thereof, or 10% below the lower listed limit and 10% above the higher listed limit for the values listed for a range.
[0040] Recent evidence including genome-wide association studies (GW AS) and differential gene expression comparing normal to affected Alzheimer’s brain tissue have identified risk and
protective variants in genes such as TREM2, PLCG2, and INPP5D that are essential to microglia function. The INPP5D gene encodes the Src homology 2 (SH2) domain-containing phosphatase- 1 (SHIP1), which is a phosphatidylinositol phosphatase that plays a key role regulating pathways downstream from TREM2. See Peng et al. 2010; Pauls et al., 2017. SHIP1 is a complex, multidomain protein with a phosphatase (Ptase) domain flanked by a pleckstrin-homology (PH) domain that binds phosphatidylinositol (3,4,5)-trisphosphate [PI(3,4,5)P3] and a C2 domain that binds phosphatidylinositol (3,4)-bisphosphate [PI(3,4)P2], See FIG. 1; Damen et al. 1996; Blunt et al., 2012. The PH and C2 domains locate and orient the catalytic site towards its PI(3,4,5)Ps substrate at the intracellular side of the membrane. The C2 domain (SEQ ID NO: 1) is essential for cellular function and interactions between the Ptase and C2 domains modulate enzymatic activity. See Le Coq et al., 2017. SHIP1 converts PI(3,4,5)P3 to PI(3,4)P2. SHIP1 also contains an N-terminal SH2 domain that binds immunoreceptor tyrosine-based activation motifs (ITAMs) and a C-terminal proline rich domain that binds many other proteins including PLCy2 and the Tec and Syk family kinases. PI(3,4,5)P3 binds and activates other PH-containing proteins such as PLCy2, PDK1, and AKT. See Scheffzek et al. 2012. Because SHIP1 binds receptor ITAMs, competes with kinases, and converts PI(3,4,5)P3 to PI(3,4)P2, it limits downstream signaling in multiple ways, and is therefore understood as a brake on microglia activation. Therefore, our therapeutic hypothesis is that inhibition of SHIP1 early in disease would increase microglial protective functions and reduce the rate of disease progression and cognitive decline in Alzheimer’s patients.
[0041] In any of the embodiments disclosed herein, the term “treating the progression of mild cognitive impairment to Alzheimer's disease” includes restraining, slowing, stopping, or reversing the progression of mild cognitive impairment to Alzheimer's disease in a patient.

[0073] EXAMPLES
[0074] The following examples are provided for the purpose of illustrating various embodiments of the disclosure and are not meant to limit the present disclosure in any fashion. The present examples, along with the methods described herein are presently representative of preferred embodiments, are provided only as examples, and are not intended as limitations on the scope of the invention. Changes therein and other uses which are encompassed within the spirit of the disclosure as defined by the scope of the claims will occur to those skilled in the art.
[0075] General Methods and Procedures
[0076] Chemical Synthesis and Validation, For each of the examples provided herein, reagents and solvents were purchased from commercial sources and used without further purification. All reactions involving air- or moisture-sensitive reagents were performed under a nitrogen or argon atmosphere. Nuclear magnetic resonance (NMR) spectra were recorded on Bruker AVANCE™ NEO 400 MHz or Bruker DRX500-1 500 MHz instruments. For ’H NMR, chemical shifts in ppm
relative to the residual solvent peak, multiplicities, coupling constants in Hertz, and numbers of protons are indicated. Reactions were routinely monitored by analytical thin layer chromatography (TLC) or liquid chromatography -mass spectroscopy (LC-MS). Analytical TLC was performed on silica gel 60 F254 silica gel plates, and 254 nm ultraviolet (UV) light and/or b staining were used for visualization. Reaction monitoring LC-MS and high-performance liquid chromatography (HPLC) purity data were obtained on a Waters™ ACQUITY® ultra-performance liquid chromatography (UPLC) sy stem equipped with a Waters™ ACQUITY® BEH C18 column (1.7 pm, 50 mm x 2.1 mm) or other specified column (see below), and either TUV and SQD2 detectors or PDA and QDa detectors. Flash normal phase (NP) or reversed-phase (RP) chromatography were performed on a Teledyne ISCO NextGen 300 instrument using prepacked silica gel or CIS- functionalized silica gel columns available from Teledyne ISCO, or on a Teledyne ISCO CombiFlash® using prepacked silica gel columns available from Agela or Welch. Preparative reverse-phase (RP) HPLC was performed on a Waters™ AutoPurification HPLC system equipped with PDA and ELSD detectors and a Waters™ XBridge C18 Prep column (10 pm, 250 mm x 19 mm). High-resolution mass spectra were obtained on an Agilent 6550 Q-TOF instrument. All compounds had >95% purity as determined by LC-MS. One of the following specified LC-MS methods was used to determine test compound purity:
[0077] Method 1 : gradient table A (below); column, Waters™ ACQUITY® HSS-T3 (1.8 pm, 100 mm x 2.1 mm); mobile phase A, 0.1% TFA in H2O; mobile phase B, ACN; flow rate, 0.3 mL/min; detection wavelength, 214 nm; column temperature, 35 °C.
[0078] Method 2: gradient table A; column, Waters™ ACQUITY® BEH C-18 (1.7 pm, 100 mm x 2.1 mm); mobile phase A, 5 mM NH4OAC in H2O; mobile phase B, ACN; flow rate, 0.3 mL/min; detection wavelength, 214 nm; column temperature, 35 °C.
[0079] Malachite Green Enzyme Assay. Enzymatic inhibitory potencies (IC50) were determined using Pl(3,4,5)P3-diC8 as a substrate at 25 °C in 50 mM 4-(2-hydroxyethyl)-l-
piperazineethanesulfonic acid (HEPES) buffer (pH7.4, 150 mM NaCl, 2 mM MgCL). Compounds diluted in dimethyl sulfoxide (DMSO) were added to 384-well plates. Enzyme solution was added. After a 20-minute incubation period, the reaction was initiated by addition of PI(3,4,5)P3-diCs. Final compound concentrations ranged from 50 nM to 950 pM. Final reaction concentrations for the PI(3,4,5)P3-diCs substrate and the enzyme were 52 pM and 10 nM respectively. The reaction was quenched after 10 minutes by adding Malachite BioMol Green (Enzo Lifesciences, PA, USA). Plates were then incubated for 30 minutes at room temperature. Absorbance (620nm) was measured using a SpectraMax® Me5 Microplate Reader (Molecular Devices, LLC, USA). IC50 values were calculated by fitting absorbance versus inhibitor concentration.
[0080] Cellular thermal shift assav (CETSA). A split Nano Luciferase assay (SplitLuc CETSA) was used to demonstrate target engagement of SH1P1 inhibitors in a physiologically relevant cellular context by quantifying changes in the thermal stability of a HiBit-labeled full length SHIP1 protein in intact cells. This assay was run in the following two formats with HMC3/HiBit-INPP5D stably transfected cells.
[0081] L Thermal shift: Cells were treated with 40 pM compound for 60 minutes, then heated with a temperature gradient covering 38-52 °C for 3 minutes before luminescence detection. Mean and standard deviation of control Tmwere determined to generate a "Mean+3SD" ATm, which was used as threshold to determine a significant ATm of compound from control. When the difference of ATm of compound treated cells from control Tm > 3SD, the compound was considered positive for target engagement, otherwise negative. SD = average standard deviation.
[0082] 2, Compound dose response: Run at target Tm (44.2°C for SHIP1) with compound dosing from 80 pM or 100 pM with 1 :3 serial dilutions to generate an 8-point curve. Cells were treated for 60 minutes before being heated at target Tm for 3 minutes before luminescence detection. An AC50 was calculated using a four-parameter logistic curve regression model with change at highest concentration noted when difference from control >3SD, otherwise AC50 marked as "NC" for not calculated.
