Abstract
Disclosed are compounds of formula (I), compositions and methods for treating of diseases, syndromes, conditions, and disorders that are affected by the inhibition of MALT1.
Description
MALT1 INHIBITORS FIELD OF THE INVENTION The present invention relates to a novel compound that is a MALT1 (mucosa-associated lymphoid tissue lymphoma translocation protein 1) inhibitor. The compound may be useful for the treatment of a disease, syndrome, condition, or disorder, particularly a MALT1-related disease, syndrome, condition, or disorder, including but not limited to, cancer and immunological diseases. The invention also relates to pharmaceutical compositions comprising one or more of such compounds, to processes to prepare such compounds and compositions, and to the use of such compounds or pharmaceutical compositions for the treatment of cancer and autoimmunological diseases, syndromes, disorders, or conditions associated with MALT1 inhibitors. BACKGROUND OF THE INVENTION MALT1 (mucosa-associated lymphoid tissue lymphoma translocation 1) is a key mediator of the classical NF ^B signaling pathway. MALT1 is the only human paracaspase and transduces signals from the B cell receptor (BCR) and T cell receptor (TCR). MALT1 is the active subunit of the CBM complex which is formed upon receptor activation. The CBM complex consists of multiple subunits of three proteins: CARD11 (caspase recruitment domain family member 11), BCL10 (B-cell CLL/Lymphoma 10) and MALT1. MALT1 affects NF ^B signaling by two mechanisms: firstly, MALT1 functions as a scaffolding protein and recruits NF- ^B signaling proteins such as TRAF6, TAB-TAK1 or NEMO-IKKα/ ^; and secondly, MALT1, as a cysteine protease, cleaves and thereby deactivates negative regulators of NF- ^B signaling, such as RelB, A20 or CYLD. The ultimate endpoint of MALT1 activity is the nuclear translocation of the NF- ^B transcription factor complex and activation of NF- ^B signaling. Constitutive activation of NF- ^B signaling is the hallmark of ABC-DLBCL (Diffuse Large B cell Lymphoma of the Activated B Cell-like subtype), the more aggressive form of DLBCL. DLBCL is the most common form of non-Hodgkin’s lymphoma (NHL), accounting for approximately 25% of lymphoma cases while ABC-DLBCL comprises approximately 40% of DLBCL. NF- ^B pathway activation is driven by mutations of signaling components, such as CD79A/B, CARD11, MYD88 or A20, in ABC-DLBCL patients. The use of BTK inhibitors, for example Ibrutinib, provides clinical proof-of-concept that inhibiting NF- ^B signaling in ABC-DLBCL is efficacious. MALT1 is downstream of BTK in the NF- ^B signaling pathway and a MALT1 inhibitor could target ABC-DLBCL patients not responding to Ibrutinib, mainly patients with CARD11 mutations, as well as treat patients that acquired resistance to Ibrutinib.
Small molecule tool compound inhibitors of MALT1 protease have demonstrated efficacy in preclinical models of ABC-DLBCL. Interestingly, covalent catalytic site and allosteric inhibitors of MALT1 protease function have been described, suggesting that inhibitors of this protease may be useful as pharmaceutical agents. The chromosomal translocation creating the API2-MALT1 fusion oncoprotein is the most common mutation identified in MALT (mucosa-associated lymphoid tissue) lymphoma. API2-MALT1 is a potent activator of the NF- ^B pathway. API2-MALT1 mimics ligand-bound TNF receptor, promotes TRAF2-dependent ubiquitination of RIP1 which acts as a scaffold for activating canonical NF- ^B signaling. Furthermore, API2-MALT1 has been shown to cleave and generate a stable, constitutively active fragment of NF- ^B-inducing kinase (NIK) thereby activating the non-canonical NF- ^B pathway. In addition to lymphomas, MALT1 has been shown to play a critical role in innate and adaptive immunity. MALT1 protease inhibitor can attenuate disease onset and progression of mouse experimental allergic encephalomyelitis, a mouse model of multiple sclerosis. Mice expressing catalytically inactive MALT1 mutant showed loss of marginal zone B cells and B1 B cells and general immune deficiency characterized as decreased T and B cell activation and proliferation. However, those mice also developed spontaneous multi-organ autoimmune inflammation at the age of 9 to 10 weeks. It is still poorly understood why MALT1 protease dead knock-in mice show a break of tolerance while conventional MALT1 KO mice do not. One hypothesis suggests the unbalanced immune homeostasis in MALT1 protease dead knock- in mice may be caused by incomplete deficiency in T and B cell but severe deficiency of immunoregulatory cells. Similarly, MALT deficiency in humans has been associated with combined immunodeficiency disorder. Given the difference between genetic mutation and pharmacological inhibition, a phenotype of MALT1 protease dead knock-in mice might not resemble that of patients treated with MALT1 protease inhibitors. A reduction of immunosuppressive T cells by MALT1 protease inhibition may be beneficial to cancer patients by potentially increasing antitumor immunity. WO2023192506 described MALT1 modulators. Thus, MALT1 inhibitors of the present invention may provide a therapeutic benefit to patients suffering from cancer and/or immunological diseases. SUMMARY OF THE INVENTION The present invention is directed to compounds of Formula (I)
and the tautomers and the stereoisomeric forms thereof, wherein R1 represents C1-4alkyl or C3-6cycloalkyl; each optionally substituted with 1, 2 or 3 substituents each independently selected from halo and -OH;
ring represents phenyl or pyridyl; Rx represents halo; n is 0, 1 or 2; Ar represents phenyl, thiazolyl, 1,2,4-thiadiazolyl, isothiazolyl, oxazolyl, pyrazolyl, pyridinonyl or pyridinyl; R4a and R4b are each independently selected from the group consisting of hydrogen; halo; C1-4alkyl; -C(=O)-NR5R6; -O-C1-4alkyl; -CN; -NR7aR8a; -C(=O)-O-R9; C3-6cycloalkyl; -O-C1-4alkyl substituted with 1, 2 or 3 halo substituents; or C1-4alkyl substituted with 1, 2 or 3 halo substituents; R2 represents C1-4alkyl; R3 represents C3-6cycloalkyl optionally substituted with one substituent selected from -NR7bR8b, 1-azetidinyl, 1-pyrrolidinyl and 1-piperidinyl; or R3 represents (a-1), (a-2), (a-3), (a-4) or (a-5):
(a-1) (a-4) (a-2) (a-5) (a-3) X1 represents O, NH or N-C1-4alkyl; X2 represents O, NH or N-C1-4alkyl; n1, n2, n3, n4, n5, n6, n7, n8, n9, n10, n11, n12, and n14 are each independently 1, 2 or 3; n13 is 0, 1 or 2; R12, R13 and R16 are each independently selected from the group consisting of hydrogen, C1-4alkyl and -S(=O)2-C1-4alkyl; R14, R15 and R17 are substituents on a carbon atom of (a-1), (a-2), (a-3), (a-4) or (a-5) and are each independently selected from the group consisting of hydrogen, C1-4alkyl and halo; which they are attached
; X3 represents CH or N; X4 represents CH or N; provided that at least one of X3 and X4 represents N; X5 represents CH or N;
X6 represents CH or N; provided that at least one of X5 and X6 represents N; R10 and R11 represent hydrogen or C1-4alkyl optionally substituted with 1, 2 or 3 halo substituents; R5, R6, R7a, R7b, R8a, R8b and R9 are each independently selected from the group consisting of hydrogen and C1-4alkyl; and the pharmaceutically acceptable salts thereof. All references to “compound(s) of Formula (I)”, in the context of this invention, might also refer to a solvate or a pharmaceutically acceptable salt form thereof, even if not explicitly referred to, and are included in the scope of the present invention. It will be clear this also applies to subgroups of Formula (I). The compounds of Formula (I) may exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water, ethanol, and the like, and it is intended that the invention embrace both solvated and unsolvated forms. As used herein, bonds shown only as solid lines and not as solid wedged or hashed wedged bonds or otherwise indicated as having a particular configuration (e.g. by a stereodescriptor such as R, S, ‘R or S’, ‘S or R’) around one or more atoms, contemplate each possible stereoisomer (stereoisomeric form), or mixture of two or more stereoisomers. Where the stereochemistry of any particular chiral atom is not specified in the structures shown herein, then all possible stereoisomers are contemplated and included as the compounds of the invention, either as a pure stereoisomer or as a mixture of two or more stereoisomers. Hereinbefore and hereinafter, the term “compound(s) of Formula (I)” is also meant to include the tautomers and the stereoisomeric forms (stereoisomers; for example enantiomers and diastereomers) thereof, even if not explicitly referred to. However, where stereochemistry, as mentioned in the previous paragraph, is specified by bonds which are shown as solid wedged or hashed wedged bonds or are otherwise indicated as having a particular configuration (e.g. R, S, ‘R or S’, ‘S or R’, trans, cis), then that stereoisomer is so specified and defined. It will be clear this also applies to subgroups of Formula (I). In the context of this invention it should be understood that bonds shown as solid lines but indicated with ‘R or S’ or ‘S or R’, are used to indicate that such a stereocenter is chirally pure but with unknown configuration (pure stereoisomers and enantiomerically pure, but absolute stereochemistry undetermined on stereocenter indicated with ‘R or S’ or ‘S or R’). Substituents on bivalent cyclic saturated (for example a cyclopropyl moiety) or partially saturated radicals may have either the cis- or trans-configuration. Terms like ‘trans A’ or ‘trans
B’ mean that one particular trans form was obtained but that the absolute stereochemistry was undetermined. Atropisomers (or atropoisomers) are stereoisomers which have a particular spatial configuration, resulting from a restricted rotation about a single bond, due to large steric hindrance. All atropisomeric forms of the compounds of Formula (I) are intended to be included within the scope of the present invention. If a compound contains a double bond, the substituents may be in the E or the Z configuration. Therefore, the invention and the term “compound(s) of Formula (I)” is also meant to include enantiomers, atropisomers, diastereomers, racemates, E isomers, Z isomers, cis isomers, trans isomers and mixtures thereof, whenever chemically possible. The meaning of all those terms, i.e. enantiomers, atropisomers, diastereomers, racemates, E isomers, Z isomers, cis isomers, trans isomers and mixtures thereof are known to the skilled person. The term “compound(s) of the (present) invention” or “compound(s) according to the (present) invention” as used herein, is meant to include the compounds of Formula (I) including tautomers and stereoisomeric forms, the pharmaceutically acceptable salt forms, and the solvates thereof. The present invention also provides a pharmaceutical composition comprising, consisting of and/or consisting essentially of a pharmaceutically acceptable carrier, a pharmaceutically acceptable excipient, and/or a pharmaceutically acceptable diluent and a compound of Formula (I). Also provided are processes for making a pharmaceutical composition comprising, consisting of, and/or consisting essentially of admixing a compound of Formula (I), and a pharmaceutically acceptable carrier, a pharmaceutically acceptable excipient, and/or a pharmaceutically acceptable diluent. The present invention further provides methods for treating or ameliorating a disease, syndrome, condition, or disorder in a subject, including a mammal and/or human in which the disease, syndrome, or condition is affected by the inhibition of MALT1, including but not limited to, cancer and/or immunological diseases, using a compound of Formula (I). The present invention also is directed to the use of any of the compounds described herein in the preparation of a medicament wherein the medicament is prepared for treating a disease, syndrome, condition, or disorder that is affected by the inhibition of MALT1, such as cancer and/or immunological diseases. The present invention is also directed to the preparation of Compounds of Formula (I)
that act as an inhibitor of MALT1. Exemplifying the invention are methods of treating a disease, syndrome, condition, or disorder mediated by MALT1, using a compound of Formula (I). In particular said disease, syndrome, condition, or disorder mediated by MALT1 is selected from the group consisting of lymphomas, leukemias, carcinomas, and sarcomas, e.g. non-Hodgkin’s lymphoma (NHL (including B-cell NHL)), diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL), follicular lymphoma (FL), mucosa-associated lymphoid tissue (MALT) lymphoma, marginal zone lymphoma, T-cell lymphoma, Hodgkin’s lymphoma, Burkitt’s lymphoma, multiple myeloma, chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), Waldenström macroglobulinemia, lymphoblastic T cell leukemia, chronic myelogenous leukemia (CML), hairy-cell leukemia, acute lymphoblastic T cell leukemia, plasmacytoma, immunoblastic large cell leukemia, megakaryoblastic leukemia, acute megakaryocytic leukemia, promyelocytic leukemia, erytholeukemia, brain (gliomas), glioblastomas, breast cancer, colorectal/colon cancer, prostate cancer, lung cancer including non-small-cell, gastric cancer, endometrial cancer, melanoma, pancreatic cancer, liver cancer, kidney cancer, squamous cell carcinoma, ovarian cancer, sarcoma, osteosarcoma, thyroid cancer, bladder cancer, head and neck cancer, testicular cancer, Ewing’s sarcoma, rhabdomyosarcoma, medulloblastoma, neuroblastoma, cervical cancer, renal cancer, urothelial cancer, vulval cancer, esophageal cancer, salivary gland cancer, nasopharangeal cancer, buccal cancer, cancer of the mouth, and GIST (gastrointestinal stromal tumor), comprising, consisting of, and/or consisting essentially of, administering to a subject in need thereof a therapeutically effective amount of any of the compounds or pharmaceutical compositions described in the present invention.

Another embodiment of the present invention is directed to a pharmaceutical composition comprising a compound of Formula (I) and uses thereof as described in any of the other embodiments. DETAILED DESCRIPTION OF THE INVENTION With reference to substituents, the term “independently” refers to the situation where several substituents are selected independently from each other and may be the same or different from each other. The term “about” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, i.e., the limitations of the measurement system. Unless explicitly stated otherwise within the Examples or elsewhere in the Specification in the context of a particular assay, result or embodiment, “about” means within one standard deviation per the practice in the art, or a range of up to 5%, whichever is larger. The transitional terms “comprising,” “consisting essentially of,” and “consisting of” are intended to connote their generally accepted meanings in the patent vernacular; that is, (i) “comprising,” which is synonymous with “including,” “containing,” or “characterized by,” is inclusive or open-ended and does not exclude additional, unrecited elements or method steps; (ii) “consisting of” excludes any element, step, or ingredient not specified in the claim; and (iii) “consisting essentially of” limits the scope of a claim to the specified materials or steps “and those that do not materially affect the basic and novel characteristic(s)” of the claimed invention. Embodiments described in terms of the phrase “comprising” (or its equivalents) also provide as embodiments those independently described in terms of “consisting of” and “consisting essentially of.” The prefix ‘Cx-y’ (where x and y are integers) as used herein refers to the number of carbon atoms in a given group. Thus, a C1-4alkyl group contains from 1 to 4 carbon atoms, and so on. The term ‘C1-4alkyl’ as used herein as a group or part of a group represents a straight or branched
chain saturated hydrocarbon radical having from 1 to 4 carbon atoms, such as methyl, ethyl, n- propyl, isopropyl, n-butyl, s-butyl, t-butyl and the like. The term ‘C3-6cycloalkyl’ as used herein as a group or part of a group defines a saturated, cyclic hydrocarbon radical having from 3 to 6 carbon atoms, such as cyclopropyl, cyclobutyl, cyclopentyl and cyclohexyl. The term “halogen” or “halo” refers to fluorine, chlorine, bromine and iodine atoms. It will be clear for the skilled person that S(=O)2 or SO2 represents a sulfonyl moiety.
. Whenever substituents are represented by chemical structure, “---” represents the bond of attachment to the remainder of the molecule of Formula (I). When any variable occurs more than one time in any constituent, each definition is independent. When any variable occurs more than one time in any formula (e.g. Formula (I)), each definition is independent. The skilled person will understand that in general, whenever the term ‘substituted’ is used in the present invention, it is meant, unless otherwise indicated or clear from the context, to indicate that one or more hydrogens, in particular from 1 to 4 hydrogens, more in particular from 1 to 3 hydrogens, preferably 1 or 2 hydrogens, more preferably 1 hydrogen, on the atom or radical indicated in the expression using ‘substituted’ are replaced with a selection from the indicated group, provided that the normal valency is not exceeded, and that the substitution results in a chemically stable compound, i.e. a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture (isolation after a reaction e.g. purification by silica gel chromatography). The skilled person will understand that combinations of substituents and/or variables are permissible only if such combinations result in chemically stable compounds. ‘Stable compound’ is in this context meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture (isolation after a reaction e.g. purification by silica gel chromatography). The skilled person will understand that the term ‘optionally substituted’ means that the atom or radical indicated in the expression using ‘optionally substituted’ may or may not be substituted (this means substituted or unsubstituted respectively).
Unless otherwise specified or clear from the context, the R4a and R4b substituents on the Ar moiety, can be substituents on carbon and/or nitrogen atoms of the Ar moiety. Lines drawn from substituents into ring systems indicate that the bond may be attached to any of the suitable ring atoms. The stereodescriptor label “R” or “(R)” at a stereocenter designates that the stereocenter is purely of the R-configuration as defined in the art; likewise, the stereodescriptor label “S” or “(S)” means that the stereocenter is purely of the S-configuration. A compound containing one stereocenter drawn without a stereo bond designation is a mixture of two stereoisomers unless otherwise indicated (for example via a stereodescriptor). A compound containing two stereocenters both drawn without stereo bond designations is a mixture of four diastereomers unless otherwise indicated (for example via stereodescriptors). Unlabeled stereocenters drawn without stereo bond designations are mixtures of the R- and S- configurations. For unlabeled stereocenters drawn with stereo bond designations, the absolute stereochemistry is as depicted. Hereinbefore and hereinafter, the term “compound(s) of Formula (I)” is meant to include the stereoisomers thereof and the tautomeric forms thereof. However, where stereochemistry, as mentioned in the previous paragraph, is specified by bonds which are shown as solid wedged or hashed wedged bonds, or are otherwise indicated as having a particular configuration (e.g. R, S), then that stereoisomer is so specified and defined. It will be clear this also applies to subgroups of Formula (I). Unless otherwise noted, it is intended that the definition of any substituent or variable at a particular location in a molecule be independent of its definitions elsewhere in that molecule. It is understood that substituents and substitution patterns on the compounds of the present invention can be selected by one of ordinary skill in the art to provide compounds that are chemically stable enough to isolate and that can be synthesized by methods set forth herein in combination with techniques known in the art.

The compounds of Formula (I) may be synthesized in the form of racemic mixtures of enantiomers which can be separated from one another following art-known resolution procedures. The racemic compounds of Formula (I) containing a basic nitrogen atom may be converted into the corresponding diastereomeric salt forms by reaction with a suitable chiral acid. Said diastereomeric salt forms are subsequently separated, for example, by selective or
fractional crystallization and the enantiomers are liberated therefrom by alkali. An alternative manner of separating the enantiomeric forms of the compounds of Formula (I) involves liquid chromatography using a chiral stationary phase. Said pure stereochemically isomeric forms may also be derived from the corresponding pure stereochemically isomeric forms of the appropriate starting materials, provided that the reaction occurs stereospecifically. In the preparation of compounds of the present invention, protection of remote functionality (e.g., primary or secondary amine) of intermediates may be necessary. The need for such protection will vary depending on the nature of the remote functionality and the conditions of the preparation methods. Suitable amino-protecting groups (NH-Pg) include acetyl, trifluoroacetyl, t-butoxycarbonyl (Boc), benzyloxycarbonyl (CBz) and 9- fluorenylmethyleneoxycarbonyl (Fmoc). The need for such protection is readily determined by one skilled in the art. Specific Examples The following examples further illustrate the present invention. EXAMPLES Several methods for preparing the intermediates and Compounds of this invention are illustrated in the following examples. Unless otherwise noted, all starting materials were obtained from commercial suppliers and used without further purification, or alternatively can be synthesized by a skilled person by using well-known methods.

Analytical Analysis The High Performance Liquid Chromatography (HPLC) measurement was performed using a LC pump, a diode-array (DAD) or a UV detector and a column as specified in the respective methods. If necessary, additional detectors were included (see table of methods below). Flow from the column was brought to the Mass Spectrometer (MS) which was configured with an atmospheric pressure ion source. It is within the knowledge of the skilled person to set the tune parameters (e.g., scanning range, dwell time…) to obtain ions allowing the identification of the compound’s nominal monoisotopic molecular weight (MW). Data acquisition was performed with appropriate software. Compounds are described by their experimental retention times (Rt) and ions. If not specified differently in the table of data, the reported molecular ion corresponds to the [M+H]+ (protonated molecule) and/or [M-H]- (deprotonated molecule). In case the compound was not directly ionizable the type of adduct is specified (i.e. [M+NH4]+, [M+HCOO]-, etc…). For
molecules with multiple isotopic patterns (Br, Cl), the reported value is the one obtained for the lowst isotope mass. All results were obtainedwith experimental uncertainties that are commonly associated with the method used.

Alternate or additional in vitro assays may be used to quantitate the ability of the inhibitor to bind to protein or nucleic acid molecules within the cell.
Inhibitor binding may be measured by radiolabelling the inhibitor prior to binding, isolating the inhibitor/target molecule complex and determining the amount of radiolabel bound. Alternatively or additionally, inhibitor binding may be determined by running a competition experiment where new inhibitors are incubated with purified proteins or nucleic acids bound to known radioligands. Detailed conditions of exemplary systems for assaying a compound of Formula (I) of the present invention as MALT1 inhibitors are set forth in the Biological Examples below. Such assays are exemplary and not intended to limit the scope of the invention. The skilled practitioner can appreciate that modifications can be made to conventional assays to develop equivalent or other assays that can be employed to comparably assess activity or otherwise characterize compounds and/or compositions as described herein. In Vitro Assays Biological Example 1 MALT1 Biochemical Protease Assay MALT1 protease activity was assessed in an in vitro assay using a tetrapeptide as substrate and full-length MALT1 protein (Strep-MALT1(1-824)-His) purified from baculovirus-infected insect cells. The tetrapeptide LRSR is coupled to AMC (7-amino-4-methylcoumarin) and provides a quenched, fluorescent substrate for the MALT1 protease (SM Biochemicals). Cleavage of AMC from the Arginine residue results in an increase in coumarin fluorescence measured at 460 nm (excitation 355 nm). The final assay buffer consisted of 10 nM FL MALT1 protein, 200 µM Ac-LRSR-AMC, 50 mM Tris pH 7.5, 0.6 M Citrate, 1 mM dithiothreitol (DTT), 1 mM ethylenediaminetetraacetic acid (EDTA), 0.05% bovine serum albumin (BSA) and 1.5% dimethyl sulfoxide (DMSO). Test compounds were spotted at 50 nL in 100% DMSO per well of a black 384-Proxiplate (Perkin Elmer). Test compound concentrations ranged from 30 µM to 0.5 nM using 11 dilution steps (1:3). Background signal was measured from control wells containing assay buffer without enzyme which functions as low control (LC). High control (HC) values were generated using the reaction with enzyme but no compound treatment. Compounds were pre-incubated with MALT1 enzyme for 50 minutes at RT. Substrate was added subsequently, and fluorescence was measured in Labsystems fluoroskan at excitation 355 nm and emission 460 nm to determine time 0. The reaction was subsequently incubated for 4 h at RT and fluorescence was measured. For IC50 calculations, timepoint 0 was subtracted from the 4 h timepoint to correct for any potential autofluorescence of the compounds. The enzyme reaction was linear during the 4 h incubation period. Characterization of the substrate Ac-LRSR-AMC determined the Michaelis constant KM at 200 µM. IC50 values were calculated using the following formula (Z prime should be >0.5):
LC = Median of the low control values = Low control: Reaction without enzyme HC= Median of the High control values = High Control: Reaction with enzyme %Effect = 100-[((sample-LC) / (HC-LC)) x 100] %Control = (sample /HC) x 100 %Controlmin = ((sample-LC) / (HC-LC)) x 100 A best-fit curve was fitted by a minimum sum of squares method to the plot of %Controlmin vs. compound concentration. From this an IC50 value (inhibitory concentration causing 50 % inhibition) can be obtained. An estimate of the slope of the plot in terms of the Hill coefficient was also obtained. IC50 Calculation: yi = LB + UB – LB 1 +10(h*(pCONCi-pIC50)) With y = estimated response UB = upper bound LB = lower bound h = Hill slope of curve CONC = concentration in “Lexis Dose Response Curve Fitting” Version 1.0.

cleavage site sequence PRLVSRGA. MALT1-induced cleavage allows for a conformational change that reestablishes a functional luciferase protein resulting in luminescence, and hence luciferase activity would be a surrogate of endogenous MALT1 protease activity. Jurkat MALT1 GloSensorTM were generated by electroporation and, selected and maintained in the presence of 0.5 mg/mL Geneticin. MALT1 protease is basally inactive in Jurkat cells and can be activated by treatment with PMA/Ionomycin. Small molecule MALT1 inhibitors added prior to PMA/Ionomycin addition prevent MALT1 protease activation and, therefore, the cleavage of the MALT1 GloSensor split luciferase reporter in a dose-dependent manner. Jurkat MALT1 GloSensorTM cells were maintained in complete RPMI 1640 media containing 10% fetal bovine serum, 10mM 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES), 100 units/mL of penicillin, 100 µg/mL of streptomycin and 0.5 mg/mL Geneticin. Prior to the assay, compounds were made 2.5-fold serial dilutions in DMSO. 100 nL of of test compounds were spotted per well of 384-well plates (Perkin Elmer, catalogue number 6007688). Jurkat cells were harvested by centrifuge at 1200 RPM for 5 min and suspended in fresh complete RPMI 1640 media with 2% GloSensor™ cAMP Reagent and preincubated for 45-60 minutes at 37 °C in a 5% CO2 incubator. A volume of 50 uL of preincubated Jurkat MALT1 GloSensorTM cells (1 x 105 cells) were seeded in each well of 384-well plate. Next, a volume 2 µL of diluted PMA / Ionomycin (2.5 ^g/mL / 25 µM respectively, Sigma, catalog number P1585 and 407953) in DMSO were added to each well. After incubation at 37 °C in 5% CO2 incubator for 4 h, luminescence was measured on the Envision (Perkin Elmer) at 37 °C. IC50 values were calculated using SmartFit in GeneData Screener ^:

Cell passage number should not exceed 30. Cells should be kept between 0.5 – 1.5 million cells per mL during culturing. For the Mesoscale assay, 100,000 OCI-Ly3 cells were seeded per well into black-colored 96- well plates with clear bottom (Corning #3904) and test compounds were added in 9 dilution steps (1:2) ranging from 15 µM to 58.6 nM (final DMSO concentration 0.3%). DMSO control wells were used to determine the maximum signal (High Control (HC)). Treatment with reference compounds at an appropriate dose served as positive control for MALT1 inhibition and was used to determine the maximum inhibition (Low Control (LC)). Compounds and cells were incubated for 24 h at 37 °C and 5% CO2 (assay volume is 150 µL). After 24 h of incubation 50 µL of the supernatant was transferred to an MSD plate (V-Plex Proinflammation Panel 1 (human) kit, Mesoscale (MSD)) and incubated for 2 h with vigorous shaking (600 rpm) at room temperature. Following incubation, plates were washed 3x with phosphate-buffered saline (PBS) + 0.05% Tween-20 and 25 µL detection antibody solution (IL-6 & IL-10 antibodies in diluent 3 (MSD)) was added per well followed by 2 h of incubation with vigorous shaking (600 rpm) at room temperature.
