MAO-B-IN-64
MAO-B-IN-64 is an orally active, blood-brain barrier-permeable reversible competitive inhibitor of monoamine oxidase B, with an IC50 of 0.35 nM against human MAO-B and a Ki of 0.22 nM for human MAO-B. MAO-B-IN-64 exhibits antioxidant effects by scavenging free radicals. MAO-B-IN-64 exerts anti-neuroinflammatory effects by inhibiting the release of pro-inflammatory factors. MAO-B-IN-64 acts as an H2S donor by releasing hydrogen sulfide. MAO-B-IN-64 can be applied in the research of Parkinson's disease.

In Vitro
MAO-B-IN-64 (30 min) is a highly potent and selective inhibitor of recombinant human MAO-B, with an MAO-B IC50 value of 0.35 nM[1].
MAO-B-IN-64 acts as a reversible MAO-B inhibitor, as the MAO-B activity of the inhibited enzyme is largely recovered after dialysis[1].
MAO-B-IN-64 is a competitive inhibitor of recombinant human MAO-B with a Ki value of 0.22 nM[1].
MAO-B-IN-64 (100 μg/mL) possesses excellent in vitro blood-brain barrier permeability and is predicted to successfully penetrate the central nervous system[1].
MAO-B-IN-64 (compound 12d) has the highest antioxidant activity among all tested target derivatives, reaching 0.59 Trolox equivalent[1].
MAO-B-IN-64 (2.5-50 μM) shows no cytotoxicity in PC12 cells up to 50 μM, and exerts significant neuroprotective effects to improve the viability of H2O2-injured PC12 cells[1].
MAO-B-IN-64 (2.5-10.0 μM) potently and dose-dependently reduces LPS-triggered intracellular ROS production in BV2 microglial cells[1].
MAO-B-IN-64 (2.5-10.0 μM) exerts potent anti-neuroinflammatory effects in in vitro LPS-activated BV2 microglial cells by suppressing multiple inflammatory mediators including NO, TNF-α, IL-6, and iNOS[1].
MAO-B-IN-64 (5.0-10 μM) effectively alleviates MPP+-induced neuronal apoptosis and rescues cell viability in SH-SY5Y cells[1].

Parmacokinetics
In Vivo
MAO-B-IN-64 (30 mg/kg; i.g.; single administration) exhibits favorable pharmacokinetic properties, good BBB penetration with an AUCbrain/plasma ratio of 0.83, and in vivo metabolic cleavage that generates the active metabolite 9a for sustained action[1].

Result:Mitigated MPTP-induced deficits in the climbing exploration test, with the 43.7 mg/kg dose producing effects slightly superior to the equimolar positive control.
Reduced the prolonged beam transit time observed in the MPTP model in the beam walking test.
Improved motor function scores in a dose-dependent manner in the traction test, with the 43.7 mg/kg group showing the best performance.
Reduced both T-turn and T-total times in the pole test at 43.7 mg/kg relative to the model group.
Moderately recovered striatal dopamine content at 8.3 mg/kg and 17.5 mg/kg, with the 43.7 mg/kg group exhibiting a significant increase in dopamine levels.
Produced a 56.4% reduction in striatal malondialdehyde content at 43.7 mg/kg relative to the model group.
Restored striatal sulfide (H2S) concentration in a dose-dependent manner, reaching 22.7 nmol/mg protein at 43.7 mg/kg.
Increased the number of tyrosine hydroxylase-positive dopaminergic neurons in the substantia nigra and striatum, preserving this neuronal population against MPTP-induced damage.
