| Description: | The effect of compounds of the invention on human plasma kallikrein activity was determined using the chromogenic substrates. In these experiments, 2 nM kallikrein was incubated with 80 μM S2302 (H-D-Pro-Phe-Arg-p-nitroaniline) in the absence or presence of increasing concentrations of compounds of the invention in a final volume of 200 μL Tris-HCl buffer (200 mM NaCl; 2.5 mM CaCl2; 50 mM Tris-HCl, pH 7.8).After incubation at 30° C., the activity of kallikrein was measured as a change in absorbance at OD 405 nm using BioTek PowerWave X340 Microplate Reader. |
