cell lines. They induced G2/M cell cycle arrest and apoptosis in the aggressive triple-negative breast cancer cell line MDA-MB-231. Among these derivatives, compound 25 with the lowest IC50 induced cell death by suppressing autophagy. This was accompanied by inhibition of autophagic flux and accumulation of autophagy protein 1 light chain 3, LC3II, and p62. The novel alkylamide derivative offers a potential
咔唑衍生物显示出抗癌活性,并且对药物开发非常感兴趣。在这项研究中,我们合成并分析了消旋霉素B的几种新的烷基酰胺衍生物,消旋霉素B是一种最初从绿藻Caulerpa消旋体中分离出来的天然吲哚[3,2- a ]咔唑分子。发现几种烷基酰胺衍生物对人乳腺癌细胞系表现出中等至强的生长抑制作用。他们在侵袭性三阴性乳腺癌细胞系MDA-MB-231中诱导G2 / M细胞周期停滞和凋亡。在这些衍生物中,具有最低IC 50的化合物25通过抑制自噬诱导细胞死亡。这伴随着自噬通量的抑制和自噬蛋白1轻链3,LC3II和p62的积累。新型烷基酰胺衍生物为人类乳腺癌提供了潜在的新疗法。
