Abstract:
The structure-activity relationship of diarylheptanoids and their analogues inhibitory of emesis induced by copper sulfate in young chicks was investigated by testing 19 compounds. The compounds are 5 diarylheptanoids isolated from Alpinia katsumadai (Zingiberacea), 5 chemical derivatives of them, 6 analogues isolated from Zingiber officinale rhizome (Zingiberaceae), and 3 analogues available on the market. Among them, two types of essential functional structure of diarylheptanoids and their analogues showed the inhibitory effects against emesis.
