NGD-4715
NGD-4715 is a drug that was developed by Neurogen, which acts as a selective, non-peptide antagonist at the melanin concentrating hormone receptor MCH1. In animal models, it has anxiolytic, antidepressant, and anorectic effects, and it has successfully passed Phase I of clinical trials in humans.
Neurogen was acquired by Ligand Pharmaceuticals in August, 2009, and NGD-4715 was not listed among its key assets. All four laboratories were closed and sold, and no employees were retained.
The structure of NGD-4715 is often confused with, for example 1--4-piperazine.
