Abstract Terpestacin a novel syncytium formation inhibitor in HIV infection, was isolated from Arthrinium sp. metabolites. The structure of terpestacin including the absolute stereochemistry was determined on the basis of spectroscopic analysis and chemical reactions. The biosynthetic pathway of terpestacin was also determined.
