  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.

  Significant enhancement in the topoisomerase I poisoning activity and cytotoxicity of 5-phenylterbenzimidazole is observed when the 2"-position is substituted with either a chloro or trifluoromethyl substituent. The influence of such substituents on the biological activity of 5.6-dibromoterbenzimidazole (6a) was also explored. In the case of either 2"-chloro-5,6-dibromoterbenzimidazole (6b) or 2"-trifluoromethyl-5

  拓扑异构酶I是在转录，翻译和有丝分裂过程中维持DNA三维结构必不可少的酶。随着有效地中毒拓扑异构酶I的新临床药物的引入，该酶已被证明是开发抗癌药物中有吸引力的分子靶标。几种苯并咪唑已被确定为有效的拓扑异构酶I毒物。关于各种苯并咪唑的结构活性数据表明，在各种苯并咪唑的5位上存在亲脂性取代基与增强的细胞毒性有关。虽然尚未评估在5位和6位上都具有取代基的效果，但先前的研究确实表明在5位上存在稠合的苯并环 6位导致拓扑异构酶I中毒活性和细胞毒性显着降低。在本研究中，我们调查了不同的苯并咪唑的5位和6位上的取代基是否会保留topo I中毒活性。合成了5-溴和5-苯基叔苯并咪唑的6-溴，6-甲氧基或6-苯基衍生物，并评估了topo I的中毒活性以及它们对人淋巴母细胞瘤细胞的细胞毒性。数据表明，此类衍生物确实保留了类似的topo I中毒活性，并具有与5-溴-或5-苯基叔苯并咪唑相当的细胞毒性。当2“被观
