A negative allosteric modulator selective for NR2B containing NMDA receptors (IC50 = 1, >100, and >100 µM for NR2B, NR2A, and NR2C, respectively). Also a potent ligand for ς1 receptor (Ki = 0.013 µM), one of the two types of unique non-opioid, non-phencyclidine brain ς receptors. Blocks neuronal voltage-gated Ca2+ channels and selectively inhibits the rapid component of the delayed rectifier K+ current (IKr). A neuroprotective agent in acute ischemic stroke. Prolongs the QT interval in EKG.
