exhibit excellent anticancer activity. Previous studies revealed that some of the synthesized 2‑chloro/nitrophenylbenzimidazole derivatives showed unexpected selective inhibition towards MDA-MB-231. In continuing efforts toward the development of a more selective anticancer drug, two series of N-sec and tert-butyl-2-phenylbenzimidazoles were designed and synthesized by substitution of chloro‑ and nitro-
乳腺癌是女性最常见的癌症类型,耐药病例的增加对新型抗癌药物的开发提出了巨大挑战。据报道,含有各种官能团的苯并咪唑衍生物表现出优异的抗癌活性。先前的研究表明,一些合成的 2-氯/硝基苯基苯并咪唑衍生物对 MDA-MB-231 表现出意想不到的选择性抑制作用。在继续努力开发更具选择性的抗癌药物的过程中,通过在苯基的不同位置取代氯基和硝基,设计并合成了两个系列的N-sec和tert -butyl-2-phenylbenzimidazoles。衍生物通过1 H NMR 表征,13 C NMR和质谱。针对 MDA-MB-231 和 MCF-7 评估了合成化合物的抗增殖活性。在这两种细胞系中,与硝基取代基相比,氯代苯并咪唑通常表现出更好的抑制作用。最有效的化合物是4b3(MCF-7 的 IC 50 = 54.62 µM),对 MDA-MB-231 细胞最有效的衍生物是4a7(IC 50 = 62.3
