Ramosetron hydrochloride was launched in Japan for chemotherapy-induced emesis. Ramosetron hydrochloride was prepared by a four step sequence via the Vilsmeier-type coupling of 1- methylindole and 5-( 1- pyrrolidoncarbonyl)-4,5,6,7-tetrahydro-Hl -benzimidazole hydrochloride. The antiemetic activity arises because it is a potent 5-HT3 receptor antagonist that is i.v. and orally active. The (R)-isomer was found to be 100 times more potent than the (S)-isomer. It was able to inhibit cisplatin-induce emesis and was 8670 times more potent than netoclopramide.
