Assay: Radioligand Binding Assay: Assessments of compound binding to human MC5R (hMC5R)) by displacement of an 125I-labeled NDP-MSH receptor ligand peptide were performed essentially as described in the data sheets produced by Perkin Elmer to accompany their frozen hMC5R membranes (Perkin Elmer catalog number RBXMC5M400UA). [125I] NDP-MSH: Radiolabeled in House and Purified by HPLC: Na125I (0.5 mCi, 17.4 Ci/mg) was added to 50 μL sodium phosphate (50 mM, pH 7.4) in an eppendorf tube precoated with IODOGEN. After incubation for 10 mins the phosphate buffer containing the iodine was added to NDP-MSH (10 μl at 1 mg/mL) in a separate eppendorf tube. This was incubated for a further 10 mins. The iodinated NDP-MSH was purified by HPLC on a Zorbax SB 300 column using solvent A: 0.05% TFA and solvent B: 90% acetonitrile 0.045% TFA with a linear gradient, 0-67% B over 60 mins. The 125I NDP-MSH eluted at 52 mins after the unlabeled starting material (48 min) and was counted and stored in the freezer. It was used within 48 hrs, as radioactive decay and ligand decomposition resulted in greatly reduced specific binding observed after 72 hrs. Incubation buffer: 25 mM HEPES-KOH (pH 7.0), 1.5 mM CaCl2, 1 mM MgSO4, 0.1 M NaCl, 1 mM 1,10-phenanthroline, and 1 Complete™ protease inhibitor tablet/100 mL (Roche, catalog number 1873580). Perkin Elmer frozen hMC5 membranes: catalog number RBXMC5M400UA, 0.4 mL/vial; 400 microassays/vial, 0.78 mg/mL protein concentration. Vials of frozen membranes were thawed rapidly immediately before use, diluted with binding buffer and vortexed. Resuspended membranes were kept on ice until they were added to the wells of the plate. Assays were performed in 96 well polypropylene plates. Membranes (0.78 μg 40 μL of a 1:40 dilution in incubation buffer) were added to [125I] NDP-MSH (0.84 nM; 2200 Ci/mmol) and test compounds in a total volume of 140 μL. This was incubated for 1 hr at 37° C. Non-specific binding was determined with 3 mM NDP-MSH. Plates were filtered using a Tomtec cell harvester with GF/A filters (Wallac) (presoaked in 0.6% polyethylenimine) and washed three times with 1.0 mL ice-cold wash buffer (the above incubation buffer without 1,10-phenanthroline and Complete™ protease inhibitor tablet). The filters were dried in a 37° C. oven, placed in a sample bag and 5 mL Betaplatescint (Wallac) was added. Prepared filters were counted in cassettes in a Microbeta Trilux (Wallac) for 1 min.

Target: Plasma kallikrein (SINGLE PROTEIN), Homo sapiens
UniProt: P03952
Assay: In Vitro Inhibition Assay: Plasma kallikrein inhibitory activity in vitro was determined using standard published methods (see e.g. Johansen et al., Int. J. Tiss. Reac. 1986, 8, 185; Shori et al., Biochem. Pharmacol., 1992, 43, 1209; Stiirzebecher et al., Biol. Chem. Hoppe-Seyler, 1992, 373, 1025). Human plasma kallikrein (Protogen) was incubated at 37° C. with the fluorogenic substrate H-DPro-Phe-Arg-AFC and various concentrations of the test compound. Residual enzyme activity (initial rate of reaction) was determined by measuring the change in optical absorbance at 410 nm and the IC50 value for the test compound was determined.

Target: Tyrosine-protein kinase BTK (SINGLE PROTEIN), Homo sapiens
UniProt: Q06187
Assay: Recombinant Human BTK Inhibition Assay: The inhibition assays were performed using the generic tyrosine kinase assay kit from C is Bio (HTRF KinEASE-TK #62TK0PEB). The assay is based on the principle of fluorescence resonance energy transfer (FRET) between the Europium Cryptate labeled anti-phosphotyrosine antibody and streptavidin labeled fluorophore, XL-665. In an uninhibited kinase reaction the biotinylated peptide substrate (Tk-Biotin) gets phosphorylated at an intermediate tyrosine site which is captured by anti-phosphotyrosine antibody which eventually acts as a FRET donor. The streptavidin labeled XL-665 binds strongly to the Tk-Biotin substrate and act as a FRET acceptor. The resultant FRET signal is measured at 665 nm. A ratio of this specific fluorescence (665 nm) to the background fluorescence (620 nm), conferred by the free antibody, is directly proportional to the kinase activity. Inhibition of the kinase activity by a pharmacological intervention such as a Btk inhibitor of the present disclosure will result into decreased FRET signal.

Assay: Intracellular Ca2+ Mobilization Assay: A monoclonal HEK-293 cell line stably transfected with a cDNA encoding for the human mGlu5a receptor was generated; for the work with mGlu5 Positive Allosteric Modulators (PAMs), a cell line with low receptor expression levels and low constitutive receptor activity was selected to allow the differentiation of agonistic versus PAM activity. Cells were cultured according to standard protocols (Freshney, 2000) in Dulbecco's Modified Eagle Medium with high glucose supplemented with 1 mM glutamine, 10% (vol/vol) heat-inactivated bovine calf serum, Penicillin/Streptomycin, 50 μg/ml hygromycin and 15 μg/ml blasticidin (all cell culture reagents and antibiotics from Invitrogen, Basel, Switzerland). bout 24 hrs before an experiment, 5×104 cells/well were seeded in poly-D-lysine coated, black/clear-bottomed 96-well plates. The cells were loaded with 2.5 μM Fluo-4AM in loading buffer (1×HBSS, 20 mM HEPES) for 1 hr at 37 °C. and washed five times with loading buffer. The cells were transferred into a Functional Drug Screening System 7000 (Hamamatsu, Paris, France), and 11 half logarithmic serial dilutions of test compound at 37 °C. were added and the cells were incubated for 10-30 min. with on-line recording of fluorescence. Following this pre-incubation step, the agonist L-glutamate was added to the cells at a concentration corresponding to EC20 (typically around 80 μM) with on-line recording of fluorescence; in order to account for day-to-day variations in the responsiveness of cells, the EC20 of glutamate was determined immediately ahead of each experiment by recording of a full dose-response curve of glutamate. Responses were measured as peak increase in fluorescence minus basal (i.e. fluorescence without addition of L-glutamate), normalized to the maximal stimulatory effect obtained with saturating concentrations of L-glutamate.

Assay: Biotin Assay: A streptavidin-coated plate (Thermo Scientific, NUNC #436014) was washed three times with 300 μL of PBS-0.05% Tween solution. A biotinylated twenty-six amino acid peptide, corresponding to the BH3 domain of Bim, with the sequence biotin-(β)A-D-M-R-P-E-I-W-I-A-Q-E-L-R-R-I-G-D-E-F-N-A-Y-Y-A-R-R-amide (SEQ ID No. 14), hereafter referred to as biotin-Bim, was obtained (Tufts). The biotin-Bim peptide was diluted to 0.018 μg/mL (5 nM) in SuperBlock blocking buffer in PBS (Thermo Scientific, #37515), and 100 μL of this solution was incubated in the streptavidin-coated plate for 2.5 hours while shaking. Separately, a compound of Formula I or Formula II, which had been prepared in a 10 mM stock DMSO solution, was then incubated with 20 nM GST-Mcl-1 fusion protein in PBS. Compounds were tested in six three-fold dilutions ranging from 20 μM to 0.6 μM, 10 μM to 0.3 or 5 μM to 0.15 μM. In addition, Bim peptide (New England Peptide) was utilized as a control and tested in six-fold dilutions ranging from 100 nM to 3.3 nM. The streptavidin-coated plate which had previously been treated with biotin-Bim peptide was then washed three times with 300 μL of PBS-0.05% Tween solution. A solution of GST-MCL-1 and a compound of Formula I or Formula II (100 μL) was then added to the streptavidin-coated plate, with two wells utilized as controls (PBS buffer only, no GST-MCL-1 or biotin-Bim) and two wells as an alternative control (containing GST-MCL-1 but no biotin-Bim), and four three-fold dilutions of DMSO (0.2%, 0.06%, 0.02%, and 0.008%). All wells containing compounds of Formula I or Formula II were loaded in duplicate. The plate was incubated for 2 hours at RT, then washed three times with 300 μL of PBS-0.05% Tween solution. Anti-GST HRP (GE Healthcare, #RPN1236) is diluted 1:20,000 in freshly prepared PBS, 0.1% Tween20, and 0.5% BSA was then added to the plate and the plate was incubated for 30 minutes. The plate was then washed five times with 300 μL of PBS-0.05% Tween solution. A solution of color reagents A (stabilized peroxide solution) and B (stabilized chrommogen solution) (R&D Systems, #DY999) is mixed in a 1:1 ratio and added to each well in a quantity of 80 μL. The wells were allowed to develop until control wells containing DMSO are blue (approximately 5-10 minutes). A solution of ELISA stop solution (1M sulfuric acid, 20 μL per well) was then added. Absorbance at 450 nM was read on a Tecan GeniosPro plate reader.

Assay: In Vitro Assay rPDE10: Rat recombinant PDE10a (rPDE10a) was expressed in Sf9 cells using a recombinant rPDE10a baculovirus construct. Cells were harvested after 48 h of infection and the rPDE10a protein was purified by metal chelate chromatography on Ni-sepharose 6FF. Tested compounds were dissolved and diluted in 100% DMSO to a concentration 100 fold of the final concentration in the assay. Compound dilutions (0.4 uL) were added in 384 well plates to 20 uL of incubation buffer (50 mM Tris pH 7.8, 8.3 mM MgCl2, 1.7 mM EGTA). 10 uL of rPDE10a enzyme in incubation buffer was added and the reaction was started by addition of 10 uL substrate to a final concentration of 60 nM cAMP and 0.008 uCi 3H-cAMP. The reaction was incubated for 60 min at rt. After incubation, the reaction was stopped with 20 uL of 17.8 mg/mL PDE SPA beads. After sedimentation of the beads during 30 min the radioactivity was measured in a Perkin Elmer Topcount scintillation counter and results were expressed as cpm. For blank values the enz

UniProt: P23458
Assay: HTRF Biochemical Assay: The reactions employed a common peptide substrate, LCB-EQEDEPEGDYFEWLW-NH2 (in-house). The basic assay protocol is as follows: First, 250 nL of diluted compounds in DMSO were dispensed into the wells of a dry 384-well Black plate (Greiner #781076) using a Labcyte Echo 555 acoustic dispenser. Subsequent reagent additions employed an Agilent Bravo. Next, 18 uL of 1.11x enzyme and 1.11x substrate in 1x assay buffer (Invitrogen kinase buffer # PV3189, 2 mM DTT, 0.05% BSA) were added to the wells and shaken and then preincubated for 30 minutes at room temperature to allow compound binding to equilibrate. After equilibration, 2 uL of 10xATP in 1x assay buffer was added to initiate the kinase reaction and the plates were shaken and then incubated at room temperature for 120 minutes. At the end of the incubation, 20 uL of 2x stop buffer (streptavidin-Dylight 650 (Thermo #84547B/100 mL), Eu-tagged pY20 antibody (Perkin Elmer #AD0067), EDTA, HEPES, and Triton) was added to quench the reaction.

Assay: Time Resolved-Fluorescence Resonance Energy Transfer (TR-FRET) Assay: The inhibition constant (Ki) is the dissociation constant of an enzyme-inhibitor complex or a protein/small molecule complex, wherein the small molecule is inhibiting binding of one protein to another protein or peptide. Where the Ki for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-XL) is greater than the limits of detection of the assay used. Where the binding selectivity ratio for a compound is represented as > (greater than) a certain numerical value, it is intended to mean that the selectivity of a particular compound for Bcl-2 over Bcl-XL is at least as great as the number indicated. Where the Ki for a compound is represented as < (less than) a certain numerical value, it is intended to mean that the binding affinity value (e.g., for Bcl-2) is lower than the limit of detection of the assay used. Inhibition constants were determined using Wang's equation (Wang Z-X).
