(a) Lineweaver–Burk plots for the inhibition of hMAO-B by compound 4b. [S], substrate concentration (μM); V, reaction velocity (nmol/min/mg protein). Inhibitor concentrations are shown at the left. Vmax values from 2xIC50 to control: 172.565, 243.902, 277.778, and 525.120 (nmol/min/mg protein). Km value of the noncompetitive inhibition: 0.443 ± 0.018 (µM). (b) Secondary plot for calculation of steady-state inhibition constant (Ki) of compound 4b. Ki was calculated as 0.346 μM.
