cytotoxicities and DNA cross-linking abilities of several alkyl-substituted diaziridinylquinones have been investigated. The cytotoxicities were determined in DT-diaphorase-rich (H460 and HT29) and -deficient (H596 and BE) cell lines. It was shown that the cytotoxicities in these cell lines correlated with the relative rates of reduction by the purified human enzyme and with the cross-linking efficiencies.
已经研究了几种烷基取代的二叠氮基奎宁醌的细胞毒性和DNA交联能力。在富含DT-黄递酶的细胞(H460和HT29)和细胞缺陷(H596和BE)的细胞系中测定细胞毒性。结果表明,这些细胞系中的细胞毒性与纯化的人酶的相对还原速率以及交联效率相关。通过循环伏安法测定,DT-心肌黄递酶的还原速率比还原电位更依赖于化合物的结构。还使用计算机模型来解释高效率的交联和还原的甲基取代的二叠氮基奎宁酮的GNC序列选择性。
