Compounds which are benzoheterocyclic distamycin derivatives of formula (I), wherein n is 2, 3 or 4; A is a heteroatom selected from O and S or is a group NR, wherein R is hydrogen or C1-C4 alkyl; B is CH or N; R1 is hydrogen or C1-C4 alkyl; G is selected from the group consisting of (a, b, c, d, e, f, g, h, i, j), and —C≡N; wherein R5, R6, R7, R8, R9, R10, R11 and R12 are, independently from each other, hydrogen or C1-C4 alkyl; T is a group of formula (II) or (III) as defined above, wherein p is 0 or 1; R2 and R3 are, independently from each other, hydrogen, C1-C4 alkyl optionally substituted by one or more fluorine atoms, or C1-C4 alkoxy; R4 is C1-C4 alkyl or C1-C3 haloalkyl; X1 and X2 are halogen atoms or pharmaceutically acceptable salts thereof; provided that at least one of R5, R6 and R7 is alkyl; are useful as antitumor agents.
式(I)的苯并杂环二聚霉素衍生物化合物,其中n为2、3或4;A为从O和S中选择的杂原子或为NR基团,其中R为氢或C1-C4烷基;B为CH或N;R1为氢或C1-C4烷基;G从(a,b,c,d,e,f,g,h,i,j)和—C≡N的群中选择;其中R5、R6、R7、R8、R9、R10、R11和R12各自独立地是氢或C1-C4烷基;T为如上所定义的式(II)或(III)的基团,其中p为0或1;R2和R3各自独立地是氢、C1-C4烷基,可选地取代一个或多个氟原子,或C1-C4烷氧基;R4为C1-C4烷基或C1-C3卤代烷基;X1和X2为卤素原子或其药学上可接受的盐;前提是R5、R6和R7中至少有一个为烷基;这些化合物作为抗肿瘤剂是有用的。
