Isolation and properties of valanimycin, a new azoxy antibiotic

Abstract

Valanimycin, a new azoxy antibiotic, was isolated from culture broths of a streptomycete. Valanimycin is an unstable oil at room temperature and active against some Gram-positive and Gram-negative bacteria, mouse leukemia L1210 cells in cultures, and prolongs the life span of mice inoculated with Ehrlich carcinoma or L1210. © 1986, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION.
