structure has been established to be 4-O-demethyl-13-dihydrodaunorubicin (4), by application of spectroscopic methods and chemical degradation. A new synthesis of 4-O-demethyl-daunorubicin (carminomycin I, 2) starting from daunomycinone, together with the comparison of the antitumor activity of the anthracycline glycosides 2 and 4 are also reported.
通过应用光谱学方法和化学降解作用,Peuceomyus peucetius的突变菌株产生了蒽环类抗生素,其结构已确定为4-O-去甲基-13-二氢柔红霉素(4)。还报道了从道诺霉素开始的4-O-去甲基柔红霉素(卡米霉素I,2)的新合成,以及蒽环类苷2和4的抗肿瘤活性的比较。
