Compounds which are acryloyl substituted distamycin derivatives of formula (I) wherein: n is 2, 3 or 4; m is 1 or 2; X and Y are the same or different and are selected, independently for each heterocyclic ring of the polyetherocyclic chain, from N and CH; R1 and R2, which are the same or different, are selected from hydrogen, halogen, and C1-C4 alkyl; R3 is hydrogen or halogen; B is selected from (a), (b), (c), (d), (e), (f), (g) and —C≡N; wherein R4, R5, R6, R7, R8, R10, R11, and R12 are, independently from each other, hydrogen or C1-C4 alkyl; and R9 is hydrogen or hydroxy, or pharmaceutically acceptable salt thereof; provided that a) at least one of R4, R5 and R6 is alkyl b) at least one of the heterocyclic rings within the polyheterocyclic chain is other than pyrole; and c) X and Y are not both N for the same heterocyclic ring; are useful as antitumor agents.
化合物是acryloyl取代的formula(I)的distamycin衍生物,其中:n为2、3或4;m为1或2;X和Y相同或不同,分别选自N和CH,为聚醚杂环链的每个杂环环;R1和R2相同或不同,选自氢、卤素和C1-C4烷基;R3为氢或卤素;B选自(a)、(b)、(c)、(d)、(e)、(f)、(g)和—C≡N;其中R4、R5、R6、R7、R8、R10、R11和R12独立地选自氢或C1-C4烷基;R9为氢或羟基,或其药用可接受的盐;条件是a)R4、R5和R6中至少有一个是烷基;b)聚杂环链内至少有一个杂环环不是吡咯;和c)X和Y对于相同的杂环环不同时为N;这些化合物可用作抗肿瘤剂。
