Abstract
As previously reported 1, 2), a new antitumor anthracycline antibiotic aclacinomycin A (ACM) was isolated from Streptomyces galilaeus MA144-M1 (ATCC 31133). It was characterized and the structure was determined. In this paper, the physicochemical properties and stability of ACM hydrochloride (ACM-HCl) are described.
