Ifenprodil (tartrate)

Ifenprodil (NP-120) tartrate, a cerebral vasodilator, is a noncompetitive NMDA receptor antagonist. Ifenprodil tartrate exerts high affinity at NR1A/NR2B receptors (IC50=0.34 μM) over 400-fold than at NR1A/NR2A receptors (IC50=146 μM) [1]. Ifenprodil tartrate is an α1 adrenergic receptor antagonist. Ifenprodil tartrate inhibits GIRK (Kir3), reduces inward currents through the basal GIRK activity. Ifenprodil tartrate has reliable inhibitory effects against A/H1N1 strains (EC50 of 6.6 µM) . Ifenprodil tartrate has neuroprotective, anticonvulsant and antinociceptive effects. Ifenprodil tartrate can be used for the study of cerebrovascular diseases and peripheral arterial obliterative disease[2][4].
