Abstract

A new anthracycline antibiotic, designated as aclacinomycin X, was isolated from the culture broth of Streptomyces galilaeus ATCC 31133, and was identified as 7-(O-rhodosaminyl-deoxyfucosyl-rednosyl)- aklavinone. Its in vitro cytotoxicity was tested against several human tumor cell lines.
