A novel series of 6-methoxy-1H-benzotriazole-5-carboxamide derivatives with dual antiemetic and gastroprokinetic activities

A novel series of 6-methoxy-1H-benzotriazole-5-carboxamide derivatives with a medium perhydroazacycle ring in the amine moiety were prepared, and their antiemetic and gastroprokinetic activities were evaluated. Among them, N-(1-ethylhexahydroazepin-3-yl)-, N-(1-ethyloctahydroazocin-3-yl)- and N-(1-ethyloctahydroazonin-3-yl)-6-methoxy-1H-benzotriazole-5-carboxamides (24, 36, 37) showed a potent antiemetic activity (inhibition of apomorphine-induced emesis in dogs) along with gastroprokinetic activity (gastric emptying in rats).
