The synthesis, biological activity, and DNA-binding properties of a series of four hybrids prepared by combining polypyrrole minor groove binders and pyrrolo[2,1-c][1,4]benzodiazepine (PBD) 13, related to the naturally occurring anthramycin (3) and DC-81 (4), have been described, and structure-activity relationships have been discussed. These hybrids 22-25 contain from one to four pyrrole units, respectively
通过将聚吡咯小沟结合剂和吡咯并[2,1-c] [1,4]苯并二氮杂((PBD)13结合而制备的一系列四个杂种的合成,生物学活性和DNA结合特性,它们与天然蒽醌有关已经描述了(3)和DC-81(4),并且已经讨论了结构-活性关系。这些杂化物22-25分别包含1-4个吡咯单元。为了研究药物/ DNA复合物的序列选择性和稳定性,对人类c-myc癌基因,雌激素受体基因和人类免疫缺陷病毒1型长末端重复序列(HIV-1 LTR)进行了DNase I印迹和阻滞聚合酶链反应(PCR)。 )基因序列。该杂合体的抗增殖活性已在体外对人髓样白血病K562和T淋巴Jurkat细胞系进行了测试,并与天然产物双他霉素A 1,其四吡咯同系物17,DC 81(4)和PBD的抗增殖作用进行了比较。甲酯12。获得的结果表明,杂合体22-25相对于双霉素A 1和PBD 12表现出不同的DNA结合活性。此外,发现杂合体22-中存在的吡咯环数之间存在直接关系。
