生物活性:
MAO-B-IN-6 is a potent, selective and orally active MAO-B inhibitor with an IC50 of 0.019 μM. MAO-B-IN-6 shows more efficacious than Safinamide in vitro and in vivo. MAO-B-IN-6 has the potential for the research of parkinson's disease (PD).

体内研究:
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%).MAO-B-IN-6 (0.08, 0.4, 2 mg/kg; i.p.) diaplays stronger MAO-B inhibitory activity.MAO-B-IN-6 (0.625, 1.25, 2.5 mg/kg; i.p.) increases the rearing activity in a dose-dependent manner.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.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.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.Pharmacokinetic Parameters of MAO-B-IN-6 in SD rats and cynomolgus monkeys.CompoundRoute Dose (mg/kg) Cmax (ng/mL)AUCt (ng·h/mL)T1/2 (h)Vss (h)Cl (mL/min/kg)F (%)

体外研究:
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.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).MAO-B-IN-6 (10 μM) shows high permeability through MDR1-MDCK II cell monolayers.
