| Description: | The inhibition of the sample on VAP-1 enzyme activity was measured by using an Amplex Red Monoamine Oxidase kit (Invitrogen #A12214). 100 nL of the gradiently-diluted to-be-tested compound (solvent DMSO) was added to a 384-well plate. 25 μL of 10 nM VAP-1 enzyme solution was added and incubated for 30 minutes at room temperature. A substrate mixture of VAP-1 enzyme (200 μM Amplex Red, 1 U/mL HRP, 1 mM Benzylamine) was added and incubated for 60 minutes at room temperature. After the incubation, the fluorescent signal was read with a microplate reader Envision (excitation light wavelength 530-560 nm, emission light wavelength 590 nm). The fluorescence signal value after the background signal was removed was analyzed by Prism software, and the IC50 of the sample against the VAP-1 enzyme was calculated. |
