    摘要:
    已经开发了新的序列选择性混合的亚胺-酰胺吡咯并苯并二氮杂(PBD)二聚体,其由DC-81和DC-81亚基的双内酰胺通过烷二氧基接头(包含三个,五个和八个碳原子)束缚在其C8位上。热变性研究表明,小牛胸腺DNA以5:1的DNA /配体比例孵育18小时后,其中一个(5c)使DeltaT(m)值增加了17.0摄氏度。因此,这些不对称分子表现出明显的DNA较小的凹槽结合亲和力和通过戊二氧链连接的5c表现出与交联DSB-120 PBD二聚体(DeltaT(m)= 15.4摄氏度)相比有效的DNA结合能力。有趣的是,这种亚胺酰胺PBD二聚体与一个5碳链连接体(不同于DSB-120)相连,其具有两个具有三个碳链接头的DC-81亚基,通过引入非共价亚基说明了非交联方面的作用。通过基于限制性内切核酸酶BamHI的抑制的限制性内切核酸酶消化测定法测量了化合物的结合亲和力。这项研究揭示了当两个结构相似部分连接在

    The present invention provides novel pyrrolo[2,1-c][1,4]benzodiazepine-glycoside prodrug of general formula 1a-b, useful as selective anticancer agents. The present invention also provides a process for the preparation of novel pyrrolo[2,1-c][1,4]benzodiazepine-glycoside prodrugs of general formula 1a-b. This invention also provides activation of these produgs by E. coli β galactosidase and envisaged that these molecules are toxic to human cancer cell lines in the presence of the enzyme E. coli β-galactosidase. The prodrugs 1a and 1b were also found to be toxic to human cancer HepG2 cells even in the absence of the E. coli □-galactosidase. The toxic effect of the molecules when activated was similar to that of the parent molecules 6a and 6b, respectively.
    本发明提供了一种新型吡咯并[2,1-c][1,4]苯二氮杂环糖苷前药,其通用公式为1a-b,可作为选择性抗癌剂。本发明还提供了一种制备新型吡咯并[2,1-c][1,4]苯二氮杂环糖苷前药的方法,其通用公式为1a-b。本发明还提供了通过大肠杆菌β-半乳糖苷酶激活这些前药,并预期这些分子在大肠杆菌β-半乳糖苷酶存在的情况下对人类癌细胞系具有毒性。前药1a和1b甚至在没有大肠杆菌β-半乳糖苷酶的情况下也被发现对人类癌细胞HepG2具有毒性。当被激活时,这些分子的毒性效果类似于相应的母体分子6a和6b。

    日期:2008.7
    Pyrrolo[2,1-c][1,4]benzodiazepine-beta-glucuronide prodrugs 15a-b, with a potential for selective therapy of solid tumors by PMT and ADEPT have been designed, synthesized and evaluated for selective cytotoxicity in the presence of the enzyme beta-glucuronidase. The prodrugs have been found to possess reduced cytotoxicity compared to the parent moieties, and are excellent substrates for the enzyme, exhibiting cytotoxicity selectively in the presence of the enzyme. Enhanced water solubility and improved stability are the other important outcomes upon modifying these molecules as their prodrugs. (C) 2008 Elsevier Ltd. All rights reserved.
