The synthesis of 4'-epi-daunorubicin and of 4'-epi-adriamycin was performed by condensation of 2,3,6-trideoxy-3-trifluoroacetamido-4-O-trifluoroacetyl-alpha-L-arabino-hexopyranosyl chloride with daunomycinone or the protected adriamycinone derivative 17, respectively. Both the alpha and beta anomers were obtained and characterized. All new compounds are biologically active in cultured cells and the
4'-表柔红霉素和4'-表阿霉素的合成是通过将2,3,6-三苯氧基-3-三氟乙酰氨基-4-O-三氟乙酰基-α-L-阿拉伯糖基-己吡喃糖酰氯与柔红霉素缩合进行的。或受保护的阿霉素衍生物17。获得并表征了α和β端基异构体。所有新化合物在培养的细胞中均具有生物学活性,并且α异头物在小鼠实验性肿瘤中显示出明显的活性。有趣的是,浓度高达5杯/毫升的4'-表阿霉素(4)对培养的心脏细胞无毒。
