General description

Ifenprodil is a phenylethanolamine, which stimulates blood circulation. It has anticonvulsant and antinociceptive properties. Ifenprodil is used to treat posttraumatic stress disorder, cerebrovascular diseases and peripheral arterial obliterative disease. It blocks G protein-coupled inwardly-rectifying potassium channels (GIRKs) and interacts with α1 adrenergic, N-methyl-D-aspartate and serotonin receptors.

Application

Ifenprodil (+)-tartrate salt has been used:
  • to test the action in a KCl-induced cortical spreading depression (CSD) animal
  • to study its effects on electrophysiological properties and spontaneous spikes in neocortical pyramidal cells
  • to investigate its therapeutic effects

Biochem/physiol Actions

NMDA antagonist acting at the polyamine site; neuroprotective agent; α-adrenergic central and peripheral vasodilator; α2 adrenergic receptor ligand.

The amino-terminal domains of NMDA receptor subunits are important for receptor assembly and desensitization, and incorporate the high-affinity binding sites for zinc and ifenprodil. These amino-terminal ligands are thought of as subunit-specific receptor inhibitors. However, multiple NMDA receptor subtypes contribute

In the late 1980s, a new class of N-methyl-D-aspartate (NMDA) receptor antagonists, exemplified by the phenylethanolamine ifenprodil (1), was identified. Initially, the mechanism of action of ifenprodil was a mystery as it was not a competitive antagonist at the glutamate
