Isolation and structures of hedaols A, B, and C, new bisnorditerpenes from a Japanese brown alga

J Nat Prod. 2001 May;64(5):653-5. doi: 10.1021/np0005661.

Abstract

New bisnorditerpenes, hedaols A (1), B (2), and C (3), were isolated from the Japanese brown alga Sargassum sp. Their structures were determined by spectroscopic analysis. The absolute stereocenter of 1 was determined by the modified Mosher's method. Hedaols showed low cytotoxicity against P388 cells.
