Abstract
Description
[0001] MAP4K1 INHIBITORS AND USE THEREOF IN THERAPY FIELD OF THE INVENTION The present invention relates to pharmaceutical compounds useful for therapy and / or 5 prophylaxis in a mammal, pharmaceutical composition comprising such compounds, and their use as MAP4K1 inhibitors, useful for treating diseases such as cancer, as well as other diseases or conditions in which MAP4K1 activity is involved. BACKGROUND OF THE INVENTION 10 Hematopoietic Progenitor Kinase 1 (HPK1), also designated as mitogen activated protein kinase 1 (MAP4K1), is a serine / threonine kinase that is a member of the Ste20-related kinase family. Predominantly expressed in hematopoietic cells, including T cells, B cells, macrophages, dendritic cells, neutrophils, and mast cells, HPK1 has been established as a key regulatory molecule in the immune signaling cascade. 15 HPK1 orchestrates a critical balance in the immune system by acting as a negative regulator of T cell and B cell signaling. Upon activation through T cell receptors (TCR) or B cell receptors (BCR), HPK1 has been shown to phosphorylate substrates such as SLP76, leading to a cascade of interactions that ultimately attenuates TCR signaling and limits levels of pro- inflammatory cytokines such as IL-2, TNF-ɑ, and IFN-γ (Hernandez et al., 2018, Cell Reports 20 25, 80–94). This modulation affects the proliferation and production of T cells, which are essential for an effective immune response against malignancies. The kinase activity of HPK1, particularly its ability to negatively influence immune cell activity, is augmented by various mediators within the tumor microenvironment (TME), such as adenosine, prostaglandin E2 (PGE2), and transforming growth factor-beta (TGFβ). These mediators can induce an 25 immunosuppressive environment that hampers the immune system's ability to combat tumor cells. In the context of immuno-oncology, HPK1’s role is twofold. On one hand, it serves as a naturalcheckpoint that prevents autoimmunity by tempering immune responses. On the other hand, its inhibitory effect on immune cells can be co-opted by tumors to evade immune surveillance. 30 The inactivation of HPK1's kinase domain has been shown to elicit robust anti-tumor immune responses (Sawasdikosol, S. et al., 2012, Immunol Res 54, 262–265), HPK1 knockout and kinase-dead models have revealed enhanced T cell function and antitumor efficacy, substantiating the hypothesis that HPK1 inhibition could potentiate immunotherapeutic outcomes (Liu et al., 2019, PLoS ONE 14(3): e0212670).35 There is thus a need for novel compounds able to inhibit HPK1 (i.e. MAP4K1), useful inparticular for treating cancer. 1

The present invention15 contemplates all such compounds, including cis- and trans-diastereomers, E- and Z-stereomers, R- and S-enantiomers, diastereomers, d-isomers, l-isomers, racemic mixturesthereof and other mixtures thereof. The term “tautomer” used in this invention refers to structural isomers of chemical compounds that readily interconvert. As an example, compounds comprising respectively an amide group 20 (-C(=O)-NH-) and an imidic acid group (-C(OH)=N-) are tautomers such as in the following structures: . The same is true of the following two indazoles: and .The term “stereoisomers” used in this invention refers to configurational stereoisomers and 25 includes geometric isomers and optical isomers. The “geometric isomers”, also called E / Z isomers or cis-trans isomers, result from the different position of substituents on a double C=C bond which can have a Z or E configuration, also called cis or trans configuration. The “optical isomers” result from the different position in space of substituents or lone pair of electrons onan atom (such as a carbon or sulfur atom) comprising four different substituents (including 30 potentially a lone pair of electron). This atom thus represents a chiral or asymmetric center. Optical isomers which are not mirror images of one another are thus designated as 19
[0020] “diastereoisomers” and optical isomers which are non-superimposable mirror images are designated as “enantiomers”. The compounds of the present invention may be in the form of free bases or pharmaceutically acceptable acid addition salts thereof. In some embodiments, the compounds of formula (I) 5 comprise an acidic proton. In such cases, the compounds of formula (I) may be in the form of free acids or pharmaceutically acceptable bases addition salts thereof.As used herein, a “pharmaceutically acceptable salt or solvate” designates a salt or solvate of a compound which is pharmaceutically acceptable, as defined above, and which possesses the pharmacological activity of the corresponding compound. 10 The nature of the salt may vary, provided that it is pharmaceutically acceptable. Suitable pharmaceutically acceptable acid addition salts of compounds for use in the present methods may be prepared from an inorganic acid or from an organic acid. Examples of such inorganic acids are hydrochloric, hydrobromic, hydroiodic, nitric, carbonic, sulfuric and phosphoric acid. Appropriate organic acids may be selected from aliphatic, cycloaliphatic, aromatic, araliphatic, 15 heterocyclic, carboxylic and sulfonic classes of organic acids, examples of which are formic, acetic, propionic, succinic, glycolic, gluconic, lactic, malic, tartaric, citric, ascorbic, glucuronic, maleic, fumaric, pyruvic, aspartic, glutamic, benzoic, anthranilic, mesylic, 4-hydroxybenzoic, phenylacetic, mandelic, embonic (pamoic), methanesulfonic, ethanesulfonic, benzenesulfonic, pantothenic, 2-hydroxyethanesulfonic, toluenesulfonic, sulfanilic, cyclohexylaminosulfonic, 20 stearic, algenic, hydroxybutyric, salicylic, galactaric and galacturonic acid. All of these salts may be prepared by conventional means from the corresponding compound by reacting, for example, the appropriate acid with any of the compounds of the invention. Examples of pharmaceutically acceptable bases addition salts include salts formed when anacidic proton present in the compound is either replaced by a metal ion, such as an alkali metal25 ion, an alkaline-earth metal ion, or an aluminium ion; or coordinated with an organic or inorganic base. Acceptable organic bases comprise diethanolamine, ethanolamine, N- methylglucamine, triethanolamine, tromethamine and the like. Acceptable inorganic bases comprise aluminium hydroxide, calcium hydroxide, potassium hydroxide, sodium carbonate and sodium hydroxide. 30 Acceptable solvates for the therapeutic use of the compounds of the present invention include conventional solvates such as those formed during the last step of the preparation of the compounds of the invention due to the presence of solvents. As an example, mention may be made of solvates due to the presence of water (these solvates are also called hydrates) or ethanol.35 The compounds of the present invention may also be in the form of N-oxides, i.e. a nitrogenatom of said compounds may be in an oxidized form. 20

[0173] II – Biological AssaysHPK1 Enzymatic Assay HPK1(h) is incubated with 8 mM MOPS pH 7.0, 0.2 mM EDTA, 0.33 mg / mL myelin basic protein, 10 mM Magnesium acetate and [γ-33P]-ATP (specific activity and concentration as 5 required). The reaction is initiated by the addition of the Mg / ATP mix. After incubation for 40 minutes at room temperature, the reaction is stopped by the addition of phosphoric acid to a concentration of 0.5%. An aliquot of the reaction is then spotted onto a filter and washed four times for 4 minutes in 0.425% phosphoric acid and once in ethanol prior to drying and scintillation counting. 10 Phosphorylation Assay In the cellular HPK1 phosphorylation assay the human T cell leukemia cell line Jurkat is used, which expresses the T-cell receptor complex including co-receptor CD3 and co-stimulatory receptor CD28. Stimulation of these cells with a CD3 / CD28 antibody complex results in activation of T-cell receptor signaling. This leads to HPK1 activation and phosphorylation of its15 target SLP76 at Ser376. Jurkat cells were plated in RPMI supplemented with 0.5% FBS in multiwell cell culture plates. After serum-starvation overnight cells were incubated with compounds (4 h at 37°C) in presence of 0.5 % FBS. For stimulation, cells were treated with 1:40 CD3 / CD28 antibody complex for 30 min at 37°C. After cell lysis quantification of SLP76 phosphorylation was 20 assessed in 96-well plates via sandwich-ELISA using a SLP76 specific capture antibody and an anti-phospho SLP76 (Ser376) detection antibody. Raw data were converted into percent substrate phosphorylation relative to solvent control (high control), which was set to 100%. The basal level (0%) was defined by the phosphorylation level of cells treated with the low control. The values for high and low control were calculated 25 by the median value of the corresponding 8 single data points. IC50 values were determined using GraphPad Prism software with constraints of bottom to 0 and top to 100 using a nonlinear regression curve fit with variable hill slope. Cytokine measurement Jurkat cells were plated in RPMI supplemented with 0.5% FBS in multiwell cell culture plates. 30 After serum-starvation overnight cells were incubated with compounds (4 h at 37°C) in presence of 0.5 % FBS. Cells treated with 1,0E-05 M Staurosporine served as low control for the cell viability assay. For stimulation, cells were then treated with 1:40 CD3 / CD28 antibody complex for 24 hours at 37°C in the presence of 10% FBS in the culture medium. Subsequently, the cell culture supernatants were collected and analyzed in the Il-2 secretion 35 assay using the Mesoscale V-PLEX Human IL-2 Kit. The IL-2 assay was performed using 1:5 diluted cell culture supernatants. An IL-2 calibrator solution provided with the kit was measured in a 1:2 dilution on each assay plate. 177
