Assay: ERK2 (20 pM) Kinase Assay: Compound potency against activated ERK2 was determined using a kinase assay that measures ERK2-catalyzed phosphorylation of biotinylated ERKtide peptide substrate ([Biotin]-AHA-K-R-E-L-V-E-P-L-T-P-S-G-E-A-P-N-Q-A-L-L-R-[NH2], the peptide sequence derived from EGF receptor: SEQ ID NO:1). The assay was carried out in 20 mM HEPES [pH 7.5], 5 mM MgCl2, 1 mM DTT, 0.01% Tween-20, 0.05% BSA using 0.02 nM ERK2, 400 nM ERKtide peptide and 35 uM ATP (all concentrations are final in the reaction) in a total volume of 10.25 uL. A 16-point, half-log dilution series of compounds at 41x final concentration was used for generating IC50 curves. Compound dilution series were prepared in 100% DMSO. ERK2 was preincubated with compounds for 30 minutes at ambient temperature. Reaction was initiated by addition of a substrate cocktail of ERKtide peptide and ATP and was allowed to proceed for 4 hours at ambient temperature. Reaction was terminated by addition of 10 uL of a 2x stop buffer consisting of 100 mM Tris-Cl [pH 7.5], 25 mM EDTA, 0.01% Tween 20, 20 ug/mL of AlphaScreen Protein A Acceptor Beads, 20 ug/mL of Streptavidin Donor Beads (PerkinElmer, Waltham, Mass.), and 1:1000 dilution phospho-EGF Receptor (Thr669) antibody (Cat #8808, Cell Signaling Technology, Danvers, Mass.). Terminated reactions were read, after overnight incubation in the dark, on an EnVision Multilabel Plate Reader (PerkinElmer, Waltham, Mass.), with excitation and emission wavelengths set to 680 nm and 570 nm, respectively. IC50 values were determined using a four-parameter fit.

Assay: Enzymatic Activity Assay: A Caliper-based kinase assay (Caliper Life Sciences, Hopkinton, Mass.) was used to measure inhibition of Btk kinase activity of a compound of Formula (IA), (I′) or (I). Serial dilutions of test compounds were incubated with human recombinant Btk (2 nM), ATP (40 μM) and a phosphoacceptor peptide substrate FAM-GEEPLYWSFPAKKK-NH2 (1 μM) at room temperature for 3 h. The reaction was then terminated with EDTA, final concentration 20 mM and the phosphorylated reaction product was quantified on a Caliper Desktop Profiler (Caliper LabChip 3000). Percent inhibition was calculated for each compound dilution and the concentration that produced 50% inhibition was calculated.

Target: Complement factor D (SINGLE PROTEIN), Homo sapiens
UniProt: P00746
Assay: In Vitro Assay: Method 1: Recombinant human factor D (expressed in E. coli and purified using standard methods) at 10 nM concentration is incubated with test compound at various concentrations for 1 hour at room temperature in 0.1 M Hepes buffer, pH 7.5, containing 1 mM MgCl2, 1 M NaCl and 0.05% CHAPS. A synthetic substrate Z-Lys-thiobenzyl and 2,4-dinitrobenzenesulfonyl-fluoresceine are added to final concentrations of 200 μM and 25 μM, respectively. The increase in fluorescence is recorded at excitation of 485 nm and emission at 535 nm in a microplate spectrofluorimeter. IC50 values are calculated from percentage of inhibition of complement factor D-activity as a function of test compound concentration.
