Abstract:
From the leaves of Miliusa mollis Pierre (Annonaceae), five new dihydrobenzofuran neolignans, namely miliumollin, 7-methoxymiliumollin, 3'-methoxymiliumollin, 4'-O-methylmiliumollin and miliumollinone, and a new 8-O-4' neolignan named miliusamollin were isolated, and their structures were elucidated through analysis of spectroscopic data. Miliumollin, 3'-methoxymiliumollin, miliumollinone and decurrenal exhibited weak cytotoxicity against KB, MCF7 and NCI-H187 cells. Miliumollinone possessed weak inhibitory effects against herpes simplex virus types 1 and 2. None of the isolates displayed inhibitory activity against avian influenza H5N1 neuraminidase.
