  2“取代的5-苯基叔苯并咪唑作为拓扑异构酶I毒物。

  摘要：

  5-苯基苯并咪唑（1）具有拓扑异构酶I毒（拓扑I）的活性，对人肿瘤细胞具有细胞毒性。当针对喜树碱抗性细胞系CPT-K5进行评估时，没有观察到交叉抗性。但是，在2“位置被1取代的衍生物确实表现出对该细胞系的交叉耐药性。该细胞系对CPT抗性的基础是它具有topo I的突变形式。这些结果表明，取代基在2”-位的“α”可能靠近野生型酶。因此，我们假设具有2“取代基的苯并咪唑能够与酶相互作用，从而影响此类topo I毒物的活性。5-苯并苯并咪唑与羟基，羟甲基，巯基，氨基，N-苯甲酰氨基甲基，氯，合成了2′-位的三氟甲基和三氟甲基。另外，制备了几种在乙基-的2-位含有甲氧基，羟基，氨基或N-乙酰氨基的2”-乙基-5-苯基叔苯并咪唑。链。这些2“-取代的5-苯基叔苯并咪唑被评估为topo I毒物并具有细胞毒活性。在2”-位存在强吸电子基团，例如氯或三氟甲基，确实增强了topo I的中毒活性。和细胞毒性。

  Terbenzimidazoles:  Influence of 2‘‘-, 4-, and 5-Substituents on Cytotoxicity and Relative Potency as Topoisomerase I Poisons

  摘要：

  Terbenzimidazoles poison the nuclear enzyme topoisomerase I and possess significant cytotoxic activity against several human tumor cell lines. The relative pharmacological activity of 4,5- and 5,6-benzoterbenzimidazoles was compared to that of 5-phenylterbenzimidazole (3). 5,6-Benzoterbenzimidazole is inactive as a topoisomerase I poison and did not exhibit significant cytotoxic activity. In contrast, 4,5-benzoterbenzimidazole retained activity as a topoisomerase I poison but exhibited weak cytotoxic activity relative to 3. While 5-(1-naphthyl)terbenzimidazole is less potent than 3 as a topoisomerase I poison and cytotoxic agent, 5-(2-naphthyl)terbenzimidazole has comparable activity to 3. The presence of a p-methoxy or p-chloro substituent on the phenyl moiety did not dramatically alter the pharmacological activity of 3. Several analogs of 3 were synthesized wherein the 2''-substituent varied from methyl, ethyl, propyl, isopropyl, phenyl to p-methoxyphenyl, Evaluation of the intrinsic activity of these analogs as topoisomerase I poisons indicates that topoisomerase I poisoning was not diminished by the presence of a methyl, ethyl, propyl, and isopropyl substituent at the 2''-position. Among the various 2''-substituted analogs evaluated, only in the case of 2''-(p-methoxyphenyl)-5-phenylterbenzimidazole was a significant decrease in cytotoxicity observed.
