Description: Safinamide, also known as FCE-26743 and EMD-1195686, is a drug indicated for the treatment of Parkinson's disease with multiple methods of action. Potential additional uses might be restless legs syndrome (RLS) and epilepsy. Safinamide is a reversible and selective monoamine oxidase B inhibitor, reducing degradation of dopamine, and a glutamate release inhibitor. It also inhibits dopamine reuptake. Additionally, safinamide blocks sodium and calcium channels. Safinamide has been approved by the European Medicines Agency for the treatment of adult patients with idiopathic Parkinson’s disease as add-on therapy to a stable dose of Levodopa (L-dopa) alone or in combination with other PD drugs in patients with mid-to-late-stage fluctuating disease.

|Biological target:||Safinamide is a potent, selective, and reversible monoamine oxidase B (MAO-B) inhibitor (IC50=0.098 µM) over MAO-A (IC50=580 µM).|
|In vitro activity:||Using patch-clamp, it was shown that safinamide reversibly inhibited sodium currents in HEK293T cells transfected with hNav1.4. At the holding potential (hp) of -120 mV, the half-maximum inhibitory concentrations (IC50) were 160 and 33 μM at stimulation frequencies of 0.1 and 10 Hz, respectively. The calculated affinity constants of safinamide were dependent on channel state: 420 μM for closed channels and 9 μM for fast-inactivated channels. The p.F1586C mutation in hNav1.4 greatly impaired safinamide inhibition, suggesting that the drug binds to the local anesthetic receptor site in the channel pore. In a condition mimicking myotonia, i.e. hp. of -90 mV and 50-Hz stimulation, safinamide inhibited INa with an IC50 of 6 μM, being two-fold more potent than mexiletine. Using the two-intracellular microelectrodes current-clamp method, action potential firing was recorded in vitro in rat skeletal muscle fibers in presence of the chloride channel blocker, 9-anthracene carboxylic acid (9-AC), to increase excitability. Safinamide counteracted muscle fiber hyperexcitability with an IC50 of 13 μM. Reference: Exp Neurol. 2020 Jun;328:113287. https://linkinghub.elsevier.com/retrieve/pii/S0014-4886(20)30118-7|
|In vivo activity:||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 Reference: J Pharmacol Exp Ther. 2018 Feb;364(2):198-206. https://jpet.aspetjournals.org/cgi/pmidlookup?view=long&pmid=29167350|
