| Description: | A rat VAP-1 enzyme (SSAO) (reference: Biol Pharm Bull. 2005 March; 28(3): 413-8) activity was measured by a radiochemistry-enzymatic assay using 14C-benzylamine as an artificial substrate. After homogenizing CHO (Chinese Hamster Ovary) cells stably expressing a rat VAP-1 enzyme (SSAO) in a 50 mM phosphate buffer containing 1% NP-40, an enzyme suspension was obtained by taking the supernatant obtained by centrifugation. The enzyme suspension was preincubated with the compound of the present invention in a 96-well microplate at room temperature for 30 minutes. Subsequently, the enzyme suspension was incubated with 14C-benzylamine (a final concentration of 1×10−5 mol/L) to a final volume of 50 mL at 37° C. for 1 hour. The enzymatic reaction was stopped by the addition of 2 mol/L (50 μL) of citric acid. The oxidation products were extracted directly in a 200 μL toluene scintillator, and the radioactivity was measured with a scintillation spectrometer. |
