A series of twenty-five 2-azitidinone (β-lactam) derivatives were synthesized and evaluated for anti-cancer properties against breast cancer, MCF-7 and MDA-MB-231. These β-lactam derivatives depicted significant cytotoxicity in cancer cell lines but not in normal human mammary epithelial cells, MEpiC. Interestingly, derivatives of 2-bromo ethyl acrylonitrile (19w) exhibited - potent anti-proliferative
合成了一系列二十五种2-氮杂环丁酮(β-内酰胺)衍生物,并评估了它们对乳腺癌,MCF-7和MDA-MB-231的抗癌性能。这些β-内酰胺衍生物在癌细胞系中表现出显着的细胞毒性,但在正常人乳腺上皮细胞MEpiC中却没有。有趣的是,2-溴乙基丙烯腈(19w)的衍生物具有很强的抗增殖活性,在ICF 50中为MCF-7为5.79±0.01μM,在MDA-MB-231中为6.86±0.009μM。此外,观察到促凋亡基因(p53,Bax,Bid)的表达增加,以及细胞周期蛋白D1,E和Cdk 2、6的mRNA表达下降,同时细胞周期停滞在G 1期。19瓦治疗显示出较高的膜联蛋白阳性细胞百分比,表明细胞凋亡的诱导。此外,对接研究证实了19w和AKT1的ATP结合催化位点之间存在相互作用。机械地,19瓦特在AKT的磷酸化和GSK-3所描绘的剂量依赖性降低β和AKT显著降低激酶活性。最后,β内酰胺衍生物19瓦特
