Abstract
Neogenkwanine I (1), a new daphnane-type diterpene with 4,7-ether group, along with four known ones (2-5), were isolated from Daphne genkwa. The structure including absolute configurations of 1 was established on the basis of NMR, 13C-NMR and ECD calculations and CD exciton chirality analysis. 13C-NMR and ECD calculations of daphnane-type diterpenes were reported here for the first time. All of the diterpenes were screened for their cytotoxic activities against MCF-7 and Hep3B cell lines. The cytotoxicity structure- activity relationship of compounds was illustrated with the absence of ortho-ester group of daphnane-type diterpenes.
