Isolation of C11 Compounds and a Cyclopropane Fatty Acid from an Okinawan Ascidian Diplosoma sp.

摘要

Pentylphenols >1 and >2, cyclopropane fatty acid >3, and cyclopentenones >4 and >5, were isolated from an ascidian, Diplosoma sp. The structures of >1−>5 were determined by spectroscopic analysis and/or synthesis. Compound >1 inhibited the division of fertilized sea urchin eggs and compound >4 showed mild cytotoxity against HCT116 cells (human colorectal cancer cell).
