The synthesis, DNA binding properties, and in vitro and in vivo anticancer activity of fifteen achiral seco-cyclopropylindoline (or achiral seco-CI) analogs (5a-o) of CC-1065 and the duocarmycins are described. The achiral seco-CI analogs contain a 4-hydroxyphenethyl halide moiety that is attached to a wide range of indole, benzimidazole, pyrrole, and pyridyl-containing noncovalent binding components
描述了CC-1065和双carocin的十五种非手性seco-环丙基二氢吲哚啉(或非手性seco-CI)类似物(5a-o)的合成,DNA结合特性以及体外和体内抗癌活性。非手性seco-CI类似物包含4-羟基苯乙基卤化物部分,该部分与各种吲哚,苯并咪唑,吡咯和含吡啶基的非共价结合组分相连。4-羟基苯乙基卤化物部分代表天然产物中存在的癸二环丙基吡咯并吲哚啉(seco-CPI)药效团的最简单模拟物,并且缺少手性中心。使用Taq DNA聚合酶终止测定和使用pBR322或pUC18质粒DNA片段的热诱导DNA切割实验确定了非手性化合物的序列和微小凹槽特异性。例如,seco-CI-InBf(5a)和seco-CI-TMI(5c)显示了对富含AT的序列的特异性,特别是通过与5'-AAAAA(865)-3'的下划线腺嘌呤-N3位置反应。这也是CC-1065和adozelesin偏爱烷基化的顺序。对非手性s
