Binding
In Vitro JAK Kinase Inhibition Test: Kinases used were human-derived JAK1, JAK2, JAK3, and TYK2 (Millipore, Germany). Each of these kinases was diluted with a suitable buffer solution as described below, and then mixed with reagents. Kinase-activity inhibitory effects of some of the compounds of Examples 1 to 73 (for example, Examples 5, 55, and 66) for JAK1, JAK2, JAK3, and TYK2 were measured at various concentrations by the above-described method, and IC50 values were determined. The IC50 values of the test compounds were calculated from % inhibition values of the compounds, by the Cheng-Prusoff method (Biochem. Pharmacol. (1973) 22, 3099-3108).
