Safinamide

Research use only, not for human use.

A potent and selective inhibitor of MAO-B with IC50 of 98 nM.

A potent and selective inhibitor of MAO-B with IC50 of 98 nM; displays >5,000-fold selectivity over MAO-A; also inhibits glutamate release and dopamine reuptake, inhibits voltage-dependent Na+ and Ca2+ channels; is used for treatment ofParkinson's disease.Parkinson's Disease Approved.

Safinamide (1–300?μM) reduces the amplitude of the peak sodium currents in a concentration-dependent manner.?When currents are stimulated to a?Vtest?of +10 mV from a?Vh?of -110 mV, the IC50?value was 262?μM. When the holding potential is depolarized to -53 mV, the inhibitory effect of safinamide with a lower IC50?value (8?μM) in rat cortical neurons.

Safinamide (intraperitoneal?injection; 90 mg/kg; once daily; 14 days) treatment prior to MCAO significantly ameliorates MCAO-caused cerebral infarction volume, neurological deficit, disruption of the brain-blood barrier (BBB), and impairs expression of tight junction protein occludin and ZO-1 in mice.Safinamide (intraperitoneal?injection; 5 mg/kg, 15 mg/kg and 30 mg/kg) dose dependently inhibits the veratridine-induced GABA release and Glu release in vivo. At the dose 30 mg/kg, ?Safinamide prevents the effect of veratridine both on Glu (treatment?F1,8=1.31; time×treatment interaction?F8,64=2.4) and GABA (treatment?F1,8=4.04; time?F8,64=3.76, time×treatment interaction?F8,64?= 2.83) release.Safinamide causes a slight, albeit not significant, reduction of veratridine-stimulated Glu release at 0.5 mg/kg and full inhibition at 5 and 15 mg/kg in rat. Animal Model:Focal cerebral ischemia C57/BL6 male mouse ModelDosage:90 mg/kg Administration:Intraperitoneal?injection; once daily; 14 days Result:Significantly decreased infarction volume in brain areas.
