title: Microbial transformations of natural antitumor agents. 13. Conversions of 13-blocked anthracyclinones.
abstract: Microbial transformation experiments were performed using 13-ketone-blocked daunomycinone derivatives which were converted into the corresponding carminomycinone derivatives by microbial O-demethylation.
