Description

A new toxic substance, Teleocidin B, was isolated from the mycellium of aSStreptomyces. The chemical structure of this compound was studied using its crystalline hydrogenated derivative (Hydroteleocidin B). As the results of these studies, a new acid anhydride named teleocidic anhydride was isolated by the oxidative degradation and it was postulated as 3, 6-dimethyl-6-amyl-1-cyclohexene-1, 2-dicarboxylic anhydride. The partial structure of Hydroteleocidin B was also discussed in this paper.
