In vitro antiproliferative screening of compounds performed on human cancer cell lines revealed that p-chlorophenyl-substituted 1,2,3-triazolyl N-isopropylamidine 10c and benzyl-substituted 1,2,3-triazolyl imidazoline 11f benzimidazoles had selective and potent cytostatic activities in the low nM range against non-small cell lung cancer cell line A549, which could be attributed to induction of apoptosis
通过在点击反应中实施微波和超声辐射,然后缩合由此获得的4-(1,2,3-),合成了一系列与1,4-二取代的1,2,3-三唑连接的新型a基2-取代的苯并咪唑。三唑-1-基)苯甲醛与邻苯二胺。在人类癌细胞系上进行的化合物的体外抗增殖筛选显示,对氯苯基取代的1,2,3-三唑基N-异丙基idine10c和苄基取代的1,2,3-三唑基咪唑啉11f苯并咪唑在低nM范围内对非小细胞肺癌A549细胞具有选择性和有效的细胞抑制活性,这可能归因于诱导凋亡和原发性坏死。额外的蛋白质印迹分析表明,化合物10c和11f之间具有不同的细胞抑制活性机制,这可能与苯并咪唑环的C-5位的1-(1,2,3-三唑基)上的芳族取代基和a基部分的性质有关。具体来说,化合物11f消除了包括TGM2,CDK9,SK1和p38 MAPK在内的几种蛋白激酶的活性,而化合物10c并未对CDK9和TGM2的活性产生深远的影响,而是显示出SK1活性的适度下调,同时p38
