New Sesquiterpenes from a Taiwanese Marine Sponge of the GenusParahigginsia
摘要:
AbstractAn undescribed Taiwanese marine sponge of the genus Parahigginsia yielded two new sesquiterpene hydrocarbons‐parahigginine (1) and parahigginone (2). The structures of the new compounds were established on the basis of NMR spectroscopic and mass spectrometric data. Compounds 1 and 2 exhibited moderate cytotoxicity against murine P‐388 and human KB‐16, A‐549, and HT‐29 tumor cells.
