hMAO-B-IN-2 (compound 6j) (0-100 μM, 15 min) exhibits potent inhibitory activity, with IC50 values of 4 nM (hMAO-B) and 6.04 nM (hMAO-A), respectively[1]. hMAO-B-IN-2 (30 min) is a reversible MAO-B inhibitor, the activity of MAO-B enzyme was restored to about 82% and 45% after compound 6j dilution to 0.1 × IC50 and 1 × 50, respectively[1]. hMAO-B-IN-2 (25 μM, 48 h) exhibits remarkable inhibitory activities against MAO-B, had good inhibition property of Aβ self-induce aggregation (40.78 ± 6.27%)[1]. hMAO-B-IN-2 (0-100 μM, 24 h) shows non-toxic at the concentrations of 25 μM[1]. hMAO-B-IN-2 (0-25 μM, 24 h) has neuroprotective capability against neurodegeneration disease, and increases cell survival rates in a dose-dependent manner[1]. Cell Cytotoxicity Assay Cell Line: SH-SY5Y neuroblastoma cell[1] Concentration: 0, 6.25, 12.5, 25, 50, 100 μM Incubation Time: 24 h Result: Showed non-toxic at the concentrations of 25 μM.
