To discover the promising antitumor agents, a series of β-carboline derivatives with nitrogen mustard moieties were designed and synthesized. Most target derivatives showed antiproliferative activity against MCF-7 and MDA-MB-231 cells. Among them, (1-methyl-9H-pyrido[3,4-b]indol-3-yl)methyl (S)-3-(4-(bis(2-chloroethyl)amino)phenyl)-2-formamidopropanoate possessed the most potent antiproliferative activity
为了发现有前景的抗肿瘤剂,设计并合成了一系列具有氮芥部分的β-咔啉衍生物。大多数目标衍生物对 MCF-7 和 MDA-MB-231 细胞显示出抗增殖活性。其中,(1-甲基-9- ħ -吡啶并[3,4- b ]吲哚-3-基)甲基(小号)-3-(4-(双(2-氯乙基)氨基)苯基)-2- formamidopropanoate具有最强的抗增殖活性,IC 50值分别为 1.79 μM 和 4.96 μM,显着高于母体化合物,功效与阳性对照阿霉素相当。更重要的是,它对人正常乳腺细胞系 MCF-10A(IC50 > 20 μM),表现出一定的选择性。随后,进一步的机制探索表明它在MDA-MB-231细胞中诱导了G2/M期细胞周期阻滞和凋亡。DCFH-DA 荧光探针试验和彗星试验表明,该化合物可导致细胞内 ROS 积累和 DNA 损伤。此外,它在体外对MDA-MB-231细胞的迁移、侵袭和粘附发挥了强效抑制作用。简而言之,(1-甲基-9
