Its structure was determined by spectroscopic methods. In the structure, a ketene function is connected with a long conjugated system via an allene unit. Irciniketene shows a moderate inhibition toward MGC and HepG2 tumor cell lines.展开更多
文摘A new diterpene, irciniketene, was isolated from the marine sponge Ircinia selaginea(Lamark) collected from the sea around Baihai, Guangxi Province. Its structure was determined by spectroscopic methods. In the structure, a ketene function is connected with a long conjugated system via an allene unit. Irciniketene shows a moderate inhibition toward MGC and HepG2 tumor cell lines.
