An anthracycline antibiotic, aclacinomycin A (aclarubicin), was produced from a mutant strain of Streptomyces lavendofoliae. The mutant strain which showed a 4-fold higher productivity of aclacinomycin A compared with the parent strain was also found to produce a significantly higher amount of aclacinomycin A than the reported production strain, Streptomyces galilaeus. The aclacinomycin A was produced up to 125 mg/l using potato starch and soybean meal as carbon and nitrogen sources, respectively, on a 3 liter scale fermentation in a 5 liter jar fermentor. The mutant strain also produced significant amount of aclacinomycins Band Y. Aclacinomycin A was isolated from the culture broth by solvent extractions and further purified by silica gel column chromatography. The yield of aclacinomycin A with over 99$%$ purity was found to be over 60$%$ starting from 3 liters of culture broth.

7-Deoxy-9-methyl aklavinones, the derivatives of aklavinone (the aglycone of extensive family of glycosidically derived from anthracycline antibiotics possessing significant activity), were synthesized by the simple and efficient reaction procedure.

As the previous HPLC method (Ogasawara et al., 1983) was described for the analysis of aclacinomycin A and some of its analogue compounds but not for aclacinomycin Y, we developed novel HPLC condition by optimizing solvent system. The newly developed solvent system allowed a complete separation of aclacinomycins Y and A, as opposed to the incomplete resolution of these two compounds in conventional method. The amounts of aclacinomycins Y and A could be accurately determined when the fermentation broth of Streptomyces lavendofoliae DKRS was analyzed by the newly developed method.
