substituted C
1-4
alkyl; m is 0 or 1; n is 1 or 2; X
1
is a halogen atom, a hydroxyl group, a C

.
6
alkoxyl group, an aryloxy group or an acyloxy group; and X

is a halogen atom, a hydroxyl group, a C
1
6 alkoxyl group, an aryloxy group or an acyloxy group; provided that at least one of R
1

4
is a group of formula (II). The N-oxides are useful prodrugs which are selectively bioreduced in hypoxic tumours to the corresponding cyclic amine derivatives. The amine compounds are cytotoxic and may be used as alkylating agents having topoisomerase II inhibiting activities in cancer therapy.
通式(I)或其盐(式I)的蒽醌化合物,其中R1至R4均选自H、C1-4烷基、X1、-NHR0N(Rs)2的群,其中R°是C1l12烷二基,每个R5是H或可选取代的C14烷基,以及式(II)的一组,其中至少有一个R6、R7和R8选自X2和X2取代的C1-4烷基,其余为H或C14烷基;R9选自H、C14烷基、X2和X2取代的C1-4烷基;m为0或1;n为1或2;X1为卤素原子、羟基、C1.6烷氧基、芳基氧基或酰氧基;X2为卤素原子、羟基、C16烷氧基、芳基氧基或酰氧基;前提是至少有一个R1至R4是式(II)的一组。N-氧化物是有用的前药,在低氧肿瘤中选择性地生物还原为相应的环状胺衍生物。胺化合物具有细胞毒性,并可用作具有拓扑异构酶II抑制活性的烷基化剂,用于癌症治疗。
