EVT-101, also known as ENS-101, is an experimental medication which originated from Roche and is under development by Evotec AG for the treatment of major depressive disorder. It acts as a selective NMDA receptor subunit 2B (NR2B) antagonist.
EVT-101 is a GluN2B antagonist, binding at the same GluN1/GluN2B dimer interface as ifenprodil but adopting a remarkably different binding mode involving a distinct subcavity and receptor interactions.
