Description

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)[1].

IC50 & Target[1]

MAO-B

0.019 μM (IC50)

MAO-A

46.365 μM (IC50)

In Vitro

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].

In Vivo

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
