Ifenprodil
Based on 10 publication(s) in Google Scholar
Ifenprodil (NP-120), a cerebral vasodilator, is a noncompetitive NMDA receptor antagonist. Ifenprodil exerts high affinity at NR1A/NR2B receptors (IC50=0.34 μM) over 400-fold than at NR1A/NR2A receptors (IC50=146 μM). Ifenprodil is an α1 adrenergic receptor antagonist. Ifenprodil inhibits GIRK (Kir3), reduces inward currents through the basal GIRK activity. Ifenprodil has reliable inhibitory effects against A/H1N1 strains (EC50 of 6.6 µM). Ifenprodil has neuroprotective, anticonvulsant and antinociceptive effects. Ifenprodil can be used for the study of cerebrovascular diseases and peripheral arterial obliterative disease.

The degree of inhibition seen with 100 μM Ifenprodil at NR1A/NR2A receptors is not altered by changes in the concentration of extracellular glycine. However, the inhibitory effect of 1 μM Ifenprodil at NR1A/NR2B receptors is reduced by increasing the concentration of glycine[1].
In oocytes injected with mRNAs for GIRK1/GIRK2, GIRK2 or GIRK1/GIRK4 subunits, Ifenprodil (3 μM) reversibly reduces inward currents through the basal GIRK activity[2].
Ifenprodil interacts with several other receptors, namely, serotonin (5-HT) subtype 1A, 5-HT2 and 5-HT3 receptors, and σ receptors at nanomolar concentrations and that it inhibits voltage-gated Ca2+ channels at micromolar concentrations[2].
