L 733,060

L-733,060 is a drug developed by Merck which acts as an orally active, non-peptide, selective antagonist for the NK₁ receptor, binding with a K_i of 0.08 nM. Only one enantiomer is active which has made it the subject of several asymmetric synthesis efforts.

L-733,060 has antidepressant and anxiolytic effects in animal studies, and reduces both the dopamine release and neurotoxicity produced by methamphetamine and cocaine. It shows anti-inflammatory and anti-hepatotoxic effects in animals, and counteracts the development of hyperalgesia following nerve injury. It also has anticancer effects in a variety of in vitro models.
