Indolo[3,2-b]quinoline derivatives (1b-i) with a methyl group at each possible position have been synthesized. The 1-methyl (1b) and 9-methyl (1i) derivatives were inactive, but the 3-methyl (1d), 4-methyl (1e), and 6-methyl (1f) derivatives exhibited high treatment/control (T/C) value and cure rates against leukemia P388 in mice. These results indicated that modification of indolo[3,2-b]quinoline
合成了在每个可能位置具有甲基的吲哚并[3,2-b]喹啉衍生物(1b-i)。1-甲基(1b)和9-甲基(1i)衍生物没有活性,但是3-甲基(1d),4-甲基(1e)和6甲基(1f)衍生物表现出较高的处理/控制(T / C)小鼠抗白血病P388的价值和治愈率。这些结果表明,吲哚[3,2-b]喹啉衍生物在3、4和6位的修饰可能是优化前导的有用方法。
