Lanicemine (AZD6765) is a low-trapping NMDA receptor antagonist developed by AstraZeneca,[1] which was being studied for the management of severe and treatment-resistant depression.[2] It was originally developed as a neuroprotective agent, but was redeveloped as an antidepressant following the observation that the NMDA receptor antagonist ketamine has potent antidepressant effects, but also has hallucinogenic side effects which make it unsuitable for use as an antidepressant in most circumstances. Lanicemine differs from ketamine in that it is a low-trapping NMDA receptor antagonist, showing similar rapid-acting antidepressant effects to ketamine in clinical trials but with little or no psychotomimetic side effects.[3] However, lanicemine did not meet study endpoints, and its development was terminated by AstraZeneca in 2013.[4]
