breast cancer cells isolated from patients. Interestingly, all these derivatives inhibited cellular proliferation in all the cancer cells that ranged between 6.2 to 38.9 μM, which is 6.7 to 1.5 fold lower than that of noscapine. Unlike previously reported derivatives of noscapine that arrests cells in the S-phase, these novel derivatives effectively inhibit proliferation of cancer cells, arrests cell
基于我们在计算机上的努力,结合微管蛋白并显示出对一组乳腺癌细胞的抗癌活性,我们提出了一类新型的Noscapine衍生物,一种镇咳植物生物碱的1,3-二炔基-Noscapinoids,Noscapine 。结构活性分析指出,异喹啉环的C-9位置可以通过偶联1,3-二炔基结构基序进行修饰,以进行合理设计,并筛选出一系列具有较强耐受性的新型1,3-二炔基-类芥子油苷(20–22)与微管蛋白的结合亲和力。选定的1,3-二炔基-类胡萝卜素类化合物20-22预测的结合能提高了-6.568 kcal / mol,对于20为-7.367 kcal / mol,对于21为-7.922 kcal / mol,对于22为-7.922 kcal / mol。与铅分子(-5.246 kcal / mol)相比。这些新颖的衍生物是化学合成的,并基于使用两种人乳腺腺癌MCF-7和MDAMB-231以及从患者中分离出的一
