| Description: | The compound was dissolved in dimethyl sulfoxide (DMSO), and diluted to an arbitrary concentration (A). A was 100-fold diluted with a buffer (0.1 M Tris (pH 8.0), 0.15 M NaCl, 10 mM CaCl2, 0.05% Brij38) (B). The r-h trypsin was diluted with a buffer to 0.088 ug/mL, and the m-trypsin was diluted with a buffer to 1/50 (C). The dilution ratio of the m-trypsin (1/50) was set to exhibit the same activity as the 0.088 ug/mL r-h trypsin as determined by kinetic analysis. The substrate solution of a substrate for the enzyme reaction, BZiPAR, (Rhodamine Reference Substrate) was diluted with a buffer to 5 umol/L (D). B; 5 uL, C; 5 uL, and D; 10 uL were added to a 384-plate, and incubated at room temperature for 30 minutes. The fluorescent signals were detected with Ex/Em = 497/520 using Tecan Safire Fluorometer. The compound was reviewed from 2500 nM to its 3-fold value, 0.0075 nM, at 12 concentrations, and the inhibitory rate of each compound was calculated. |
