摘要：
Four new homoverrucosane-type diterpenes (1-4) and two known analogs (5-6) were isolated from the marine sponge Halichondria sp. Their structures including absolute configurations were determined by combination of spectroscopic analyses, theoretical calculations and comparison with data of literatures. The cytotoxicity against human multiple myeloma cell line RPMI-8266 of compounds 1-4 was evaluated, but none showed activity (IC50 > 10 mu M). It was the first report that homoverrucosanes isolated from the marine sponge Halichondria sp. (C) 2020 Published by Elsevier Ltd.
