摘要:
Metabolites from Microorganisms. 160th Communication. Conocandin, a new Fungistatic Antibiotic.From a strain of Hormococcus conorum (SACC. ET ROUM.) ROBACK A 32′287, conocandin, a novel type C18‐fatty acid with high and specific in vitro fungistatic activity was isolated by means of counter current distribution and silicagel chromatography. The antibiotic is a viscous oil with the molecular formula C18H30O3. It is characterized by IR. and NMR. spectra, ester derivatives and the products of acid rearrangement and ozonolytic degradation. The structure of (E)‐2‐methylidene‐10‐methyl‐trans‐3,4‐epoxy‐9‐hexadecenoic acid (1) is proposed.
