Terpestacin, a new syncytium formation inhibitor from Arthrinium sp.

Abstract

Terpestacin, a new antibiotic which inhibits syncytium formation, was isolated from Arthrinium sp. FA1744 (ATCC 74132). The structure of terpestacin was elucidated as a bicyclic sesterterpene on the basis of spectroscopic data and chemical derivatization.
