Antibiotics from basidiomycetes. X. Scorodonin, a new antibacterial and antifungal metabolite from Marasmius scorodonius (Fr.) Fr.

Abstract
Scorodonin, a novel biologically active metabolite, was isolated from submerged cultures of the mushroom M. scorodonius (Fr.) Fr. Its structure was determined by chemical and physical methods. The antibiotic inhibits the growth of bacteria, yeasts and filamentous fungi. In cells of the ascitic form of Ehrlich carcinoma, the incorporation of thymidine and uridine into DNA and RNA is strongly inhibited by scorodonin, whereas the incorporation of leucine into protein is not affected.
