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 Ki of 0.08 nM.[1] Only one enantiomer is active which has made it the subject of several asymmetric synthesis efforts.[2][3][4]

L-733,060 has antidepressant[5][6] and anxiolytic effects in animal studies,[7] and reduces both the dopamine release and neurotoxicity produced by methamphetamine and cocaine.[8][9][10][11][12] It shows anti-inflammatory and anti-hepatotoxic effects in animals,[13][14] and counteracts the development of hyperalgesia following nerve injury.[15][16] It also has anticancer effects in a variety of in vitro models.[17][18][19]
