Assay: BACE1 Cell-Free Assay: A synthetic APP substrate that can be cleaved by beta-secretase having N-terminal biotin and made fluorescent by the covalent attachment of Oregon Green at the Cys residue is used to assay beta-secretase activity in the presence or absence of the inhibitory compounds. The substrate is Biotin-GLTNIKTEEISEISY^EVEFR-C[Oregon Green]KK-OH. The BACE1 enzyme is affinity purified material from conditioned media of CHO-K1 cells that have been transfected with a soluble BACE construct (BACE1deltaTM96His). Compounds are incubated in a log dose response curve from a top concentration of 100 uM with BACE1 enzyme and the biotinylated fluorescent peptide in 384-well black plates (Thermo Scientific #4318). BACE1 is at a final concentration of 0.1 nM with a final concentration of peptide substrate of 150 nM in a reaction volume of 30 uL assay buffer [100 mM sodium acetate, pH 4.5 (brought to pH with acetic acid), and 0.001% Tween-20]. Plates are covered and incubated for 3 hours at 37° C. The reaction is stopped with the addition of 30 uL of 1.5 uM Streptavidin (Pierce, #21125). After a 10 minute incubation at room temperature, plates are read on a PerkinElmer EnVision for fluorescence polarization (Ex485 nm/Em530 nm). The activity of the beta-secretase enzyme is detected by changes in the fluorescence polarization that occur when the substrate is cleaved by the enzyme. Incubation in the presence of compound inhibitor demonstrates specific inhibition of beta-secretase enzymatic cleavage of the synthetic APP substrate.

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: Inhibition Assay: The potency of the compounds of the invention is ascertained in an in vitro inhibition assay.

Assay: Fluorescence Polarization Assay: In a typical experiment the PDE10 inhibitory activity of the compounds of the present invention was determined in accordance with the following experimental method. PDE10A2 was amplified from human fetal brain cDNA (Clontech, Mountain View, Calif.) using a forward primer corresponding to nucleotides 56-77 of human PDE10A2 (Accession No. AF127480, Genbank Identifier 4894716), containing a Kozak consensus sequence, and a reverse primer corresponding to nucleotides 2406-2413 of human PDE10A2 (Accession No. AF127480, Genbank Identifier 4894716). Amplification with Easy-A polymerase (Stratagene, La Jolla, Calif.) was 95° C. for 2 minutes followed by thirty three cycles of 95° C. for 40 seconds, 55° C. for 30 seconds, and 72° C. for 2 minutes 48 seconds. Final extension was 72° C. for 7 minutes. The PCR product was TA cloned into pcDNA3.2-TOPO (Invitrogen, Carlsbad, Calif.) according to standard protocol. AD293 cells with 70-80% confluency were transiently transfected with human PDE10A2.

Target: Tyrosine-protein kinase SYK (SINGLE PROTEIN), Homo sapiens
UniProt: P43405
Assay: Homogeneous Time-Resolved Fluorescence (HTRF) Assay: A recombinant GST-hSyk fusion protein was used to measure potency of compounds to inhibit human Syk activity. The recombinant human GST-Syk (Carna Biosciences #08-176) (5 pM final concentration) was incubated with various concentrations of the inhibitor diluted in DMSO (0.1% final concentration) for 10 minutes at room temperature in 15 mM Tris-HCl (pH 7.5), 0.01% tween 20, 2 mM DTT in 384 well plate format. To initiate the reaction the biotinylated substrate peptide (250 nM final concentration) that contains the phosphorylation site for Syk was added with magnesium (5 mM final concentration) and ATP (25 uM final concentration). Final volume of the reaction was 10 uL. Phosphorylation of the peptide was allowed to proceed for 45x at room temperature. To quench the reaction and detect the phosphorylated product, 2 nM of a Europium-anti-phosphotyrosine antibody (Perkin Elmer #AD0161) and 70 nM SA-APC (Perkin-Elmer #CR130-100) were added together in 15 mM Tris pH 7.5.

Assay: Thallium Flux Assay: The ROMK channel functional thallium flux assay is performed in 384 wells, using the FLIPR-Tetra instrument. HEK-hKir1.1 cells are seeded in Poly-D-Lysine microplates and kept in a 37° C.-10% CO2 incubator overnight. On the day of the experiment, the growth media is replaced with the FluxOR reagent loading buffer and incubated, protected from light, at ambient temperature (23-25° C.) for 90 min. The loading buffer is replaced with assay buffer+/-test compound followed by 30 min incubation at ambient temperature, where the Thallium/Potassium stimulant is added to the microplate.Step Protocol 1. Seed HEK-hKir1.1 cells (50 uA at 20,000 cells/well) in 384-well PDL coated Microplates 2. Allow cells to adhere overnight in humidified 37° C./10% CO2 incubator 3. Completely remove cell growth media from microplate and replace with 25 ul loading buffer 4. Incubate Microplate at room temperature, protected form light, for 90 min.

Assay: LanthaScreen™ Assay (5 mM ATP): a) 400 nl of a 1:2.15 serial dilution of test compound(98 μM top assay concentration) is spotted via Labcyte Echo to certain wells in a 384 well black, untreated plate. Control wells contain 400 nl of either DMSO or 400 nl of a known inhibitor in DMSO. b) 10 μl of a 2.5 nM LRRK2(G2019S mutation, GST-LRRK2(amino acids 970-2527)) enzyme solution in 1× assay buffer(50 mM Tris pH 8.5, 10 mM MgCl2, 0.01% Brij-35, 1.0 mM EGTA, 2 mM DTT, 0.05 mM NaVO4) is added to all wells. c) A 30 minute room temperature incubation is followed by addition of 10 μl of 800 nM fluorescein labeled LRRKtide peptide substrate and 10 mM ATP solution in 1× assay buffer to all wells. d) After a 35 minute room temperature incubation, 20 μl of TR-FRET Dilution Buffer(Invitrogen PV3756B) containing 4 nM Tb-labeled anti-phospho LRRKtide antibody and 20 mM EDTA is added to all wells. e) Plates are incubated at room temperature for 1 hour and read on an Envision™ multi-mode plate reader with LanthaScreen™ settings.
