Tropanserin (INN; MDL-72,422) is a drug which acts as a potent and selective 5-HT3 receptor antagonist.[1] It was investigated in clinical trials for the treatment of migraine in the 1980s but was never marketed.[2]


Tropanserin can be prepared by the reaction of tropine with 3,5-dimethylbenzoyl chloride.
