The title compounds, (+)-13-methyl-13-dihydro-4-demethoxydaunorubicin hydrochloride (8·HCl) and (+)-13-methyl-13-dihydrodaunorubicin hydrochloride (9·HCl), were prepared from (+)-4-demethoxydaunomycinone (13) and (+)-daunomycinone (18), respectively, by silylation of the C7-hydroxy group, addition of methylmagnesium bromide to the C13-carbonyl group, and direct glycosidation of the 7-O-silyl anthracyclinones with the daunosamine derivative (anthracycline numbering). In the P388 in vitro test, 8·HCl was several hundred-fold more active than adriamycin hydrochloride (1·HCl). Notable anticancer activity, equivalent to that of adriamycin hydrochloride, was also observed in the P388 in vivo test of 8·HCl.
标题化合物(+)-13-甲基-13-二氢-4-去甲氧基多柔比星盐酸盐(8·HCl)和(+)-13-甲基-13-二氢多柔比星盐酸盐(9·HCl)分别是由(+)-4-去甲氧基多柔霉素酮(13)和(+)-多柔霉素酮(18)通过对C7-羟基的硅化、向C13-羰基加入溴化甲基镁,以及将7-O-硅醇基的蒽环类化合物与多柔糖衍生物直接糖苷化制备而成。在P388体外测试中,8·HCl的活性是阿霉素盐酸盐(1·HCl)的几百倍。此外,在8·HCl的P388体内测试中也 observed 到与阿霉素盐酸盐相等的显著抗癌活性。
