A new antibiotic, setomimycin, was isolated from the culture broth of strain AM-2947, which was identified as Streptomyces pseudovenezuelae. The compound is a weakly acidic substance, and has UV-absorption at 228, 268 and 422 nm and a molecular formula of C34H28O9 (MW 580). It is active against Gram-positive bacteria including Mycobacteria, and has antitumor activity against Sarcoma-180 solid tumor in mice.
