Target: MAO-B

Safinamide (EMD 1195686; FCE 26743; ) is a highly selective and reversible monoamine oxidase type B (MAO-B) inhibitor that increases neostriatal dopamine concentration. In addition, Safinamide (EMD 1195686; FCE 26743; ) is voltage-dependent sodium and calcium channel blocker. Safinamide (EMD 1195686; FCE 26743; ) appears to bind to the batrachotoxin-sensitive site 2 of the voltage-sensitive sodium channels. Safinamide blocks N and L-type calcium channels and inhibits glutamate and aspartate release from synaptic terminals.
