MAO-B-IN-6 (compound D5) (Sf9 cells) shows inhibitory activities towards monoamine oxidase (MAO) with the IC50s of 46.365 µM and 0.019 µM for MAO-A and MAO-B, respectively[1]. MAO-B-IN-6 shows no inhibition potential towards cytochrome P450 (IC50=>29 µM for 1A2, 2B6, 2C8, 2C9, 2C19, 2D6 and 3A4/5 enzymes)[1]. MAO-B-IN-6 (10 µM) shows high permeability through MDR1-MDCK II cell monolayers[1].

MAO-B-IN-6 (1 mg/kg, i.v.; 5 mg/kg, p.o.) shows oral bioavailability in rats (F=55.2%) and monkeys (F=107.1%)[1]. MAO-B-IN-6 (0.08, 0.4, 2 mg/kg; i.p.) diaplays stronger MAO-B inhibitory activity[1]. MAO-B-IN-6 (0.625, 1.25, 2.5 mg/kg; i.p.) increases the rearing activity in a dose-dependent manner[1]. MAO-B-IN-6 (0.625, 1.25, 2.5 mg/kg; i.p.) shows a potential efficacy for alleviating dopamine (DA) deficits in the MPTP-induced Parkinson's disease (PD) mouse model[1]. MAO-B-IN-6 (0.156, 0.312, 0.625, 1.25 mg/kg; i.p.) increases the effect of levodopa on dopamine concentration in the striatum[1]. MAO-B-IN-6 (0.156, 0.312, 0.625, 1.25 mg/kg; i.p.) shows a significant reduction in galantamine-induced tremulous jaw movements[1].
