7-substituted camptothecin derivatives of the general formula
wherein R represents-CHO,-CH2OR',-CH(OR')2 or-CH=N-X where R' is a lower alkyl group having from 1 to 6 carbon atoms or a phenylalkyl group having from 1 to 3 carbon atoms in the alkylene moiety thereof, and X is a hydroxyl group or -NR1R2 where R1 and R are the same or different and each represent hydrogen atom or a lower alkyl group having from 1 to 6 carbon atoms, or when R' is hydrogen, R2 may be a lower alkyl group having from 1 to 6 carbon atoms, a substituted or unsubstituted aryl group, a carbamoyl group, an acyl group, an aminoalkyl group or an amidino group, or when R' is a lower alkyl group, R2 may be an aminoalkyl group, or R1 and R2 may be combined together with the nitrogen atom to which they are attached to form a heterocyclic group which may be interrupted by one or two nitrogen, oxygen and/or sulfur atoms, and the quaternary salts thereof.
通式为 7-取代的喜树碱衍生物
其中 R 代表-CHO、-CH2OR'、-CH(OR')2 或-CH=N-X 其中 R'是具有 1 至 6 个碳原子的低级烷基或在其亚烷基中具有 1 至 3 个碳原子的苯基烷基,X 是羟基或-NR1R2 其中 R1 和 R 相同或不同,各自代表氢原子或具有 1 至 6 个碳原子的低级烷基,或当 R' 是氢时,R2 可以是具有 1 至 6 个碳原子的低级烷基、取代或未取代的芳基、氨基甲酰基、酰基、氨基烷基或脒基,或当 R' 为低级烷基时,R2 可为氨基烷基,或 R1 和 R2 可与所连接的氮原子结合在一起,形成可被一个或两个氮、氧和/或硫原子间断的杂环基团及其季盐。
