Binding
Enzymatic Inhibition Assay: Inhibitors were evaluated in triplicate in eight-point dilutions (3-fold dilutions) during the enzymatic reactions. TgCDPK1 enzymatic inhibition was determined with a coupled luciferase assay (Kinaseglo®). 2.1 nM TgCDPK1 and 20 μM BioSyntide-2 (American Peptide Company, Inc. Sunnyvale, Calif.)) were incubated in 25 μL of buffer containing 1 mM EGTA (pH 7.2), 10 mM MgCl2, 20 mM HEPES, pH 7.5 (KOH), 0.1% BSA, and 2 mM CaCl2. The reaction was initiated with the addition of ATP at a 10 μM final concentration. After incubating at 30° C. for 90 min., changes in ATP concentration were determined by adding Kinaseglo® luciferase reagent (Promega, Madison, Wis.) and measuring luminescence with a MicroBeta2 multi-label plate reader (Perkin Elmer, Waltham, Mass.). Results were converted to percent inhibition, and IC50 values were calculated using nonlinear regression analysis in GraphPad Prism.
