using (1)H NMR, (13)C NMR, high resolution MS and melting points. Evaluation of antiproliferative activity of the benzimidazole analogues against MCF-7 and MDA-MB-231 revealed several compounds with unexpected selective inhibitions of MDA-MB-231 in micromolar range. All analogues were found inactive towards MCF-7. The most potent inhibition against MDA-MB-231 human breast cancer cell line came from the
在聚焦微波辐射下,通过将3-氨基-4-丁基氨基苯甲酸乙酯与苯甲醛的各种取代的亚硫酸氢盐加合物缩合,在2-3.5分钟内以85-96%的产率合成了一系列新的N-仲/叔丁基2-芳基苯并咪唑衍生物。 。苯并咪唑类似物使用(1)H NMR,(13)C NMR,高分辨率MS和熔点进行表征。苯并咪唑类似物对MCF-7和MDA-MB-231的抗增殖活性的评估显示了几种化合物在微摩尔范围内具有意想不到的选择性抑制MDA-MB-231的作用。发现所有类似物对MCF-7无活性。对MDA-MB-231人乳腺癌细胞系最有效的抑制作用来自未取代的2-苯基苯并咪唑10a。
