Paralemnolide A, an Unprecedented Bisnorsesquiterpene from the Taiwanese Soft Coral <em>Paralemnalia thyrsoides</em><em></em>

Abstract

Paralemnolide A (<strong>1</strong>), possessing an unprecedented bisnorsesquiterpene skeleton, was isolated from the soft coral <em>Paralemnalia thyrsoides</em>. The structure of paralemnolide A was elucidated by extensive analysis of spectroscopic data. The anti-HCMV (human cytomegalovirus) activity of <strong>1</strong> and its cytotoxicity against selected cell lines were evaluated.
