Biological Activity for (+)-MK 801 maleate

(+)-MK 801 maleate is a high affinity (Ki = 37.2 nM), selective and non-competitive NMDA receptor antagonist. (+)-MK 801 maleate acts by binding to a site located within the NMDA associated ion channel and thus prevents Ca2+ flux. It is an effective anti-ischemic agent in several animal models. (+)-MK 801 maleate increases motor activity in rat models. (+)-MK 801 maleate inhibits proliferation and increases apoptosis in hippocampal neural stem cells (NSCs). (+)-MK 801 maleate induces schizophrenia-like symptoms in rodents.

(-)-enantiomer also available.
