By employing various novel reactions developed in our synthetic studies on 4-demethoxy-adriamycin and 4-demethoxydaunorubicin, three examples of the title compounds (7a-c) were prepared from (R)-2, 5, 12-trihydroxy-1, 2, 3, 4-tetrahydro-6, 11-naphthacenedione-2-carboxylic acid (9). While 7a-c showed marked cytotoxicity against P388 in vitro, it was found that 7a (carrying a nonanoyl group at the C9-position) was ineffective against P388 in vivo.
通过采用我们在 4-去甲氧基阿霉素和 4-去甲氧基杜诺比星合成研究中开发的各种新型反应,从(R)-2, 5, 12-三羟基-1, 2, 3, 4-四氢-6, 11-萘醌-2-羧酸(9)制备出了三种标题化合物(7a-c)。虽然 7a-c 在体外对 P388 显示出明显的细胞毒性,但研究发现 7a(在 C9 位带有一个壬酰基)在体内对 P388 无效。
