9a-tetrahydrocyclopropa[c]benz[e]indol-4-one (CBI) analogues of CC-1065 and the duocarmycins containing dimeric monocyclic, bicyclic, and tricyclic heteroaromatic replacements for the DNA-binding domain are described. This systematic study revealed clear trends in the structural requirements for observation of potent cytotoxic activity and DNA alkylation efficiency, the range of which spans a magnitude of >
CC-1065和Duocarmycins的132(+)-1,2,9,9a-四氢环丙烷[c]苯并[e]吲哚-4-酮(CBI)类似物的文库的溶液相平行合成和评价描述了含有DNA结合域的二聚单环,双环和三环杂芳族取代基。这项系统的研究揭示了用于观察有效细胞毒性活性和DNA烷基化效率的结构要求的明显趋势,其范围跨越>或= 10000倍。与相关研究相结合,这些结果表明,DNA结合结构域的作用不仅限于提供DNA结合的选择性和亲和力(性能提高10到100倍),
