activity was evaluated against four cell lines derived from human tumours (A549 - lung, MCF-7 - breast, Hep G2 - hepatocellular carcinoma, and HT-144-melanoma). Cell viability was significantly reduced in the MCF-7 cell line when compounds 4b, 4b' and 5a were used; IC50 values were lower than those found for their precursors (eugenol and dihydroeugenol) and sulfanilamide. We observed that 4b induced cell
癌症是世界上最重要的公共卫生问题之一,也是医学的主要挑战之一。对于基于磺酰胺的化合物,已报道了不同的生物学效应,包括抗菌,抗真菌和抗肿瘤活性。在此,合成了一系列基于苯丙烷的磺酰胺类药物(4a,4a',4b,4b',5a,5a',5b和5b'),并评估了它们对源自人类肿瘤的四种细胞系(A549-肺)的细胞毒性活性,MCF-7-乳腺癌,Hep G2-肝细胞癌和HT-144-黑色素瘤)。当使用化合物4b,4b'和5a时,MCF-7细胞系中的细胞活力显着降低。IC50值低于其前体(丁子香酚和二氢丁香酚)和磺胺的含量。我们观察到4b诱导细胞周期停滞在G1 / S过渡。这可能是由于其减少细胞周期蛋白D1和细胞周期蛋白E表达的能力。此外,与对照组相比,经处理的培养物中膜联蛋白V阳性的细胞数量增加证明了4b还诱导MCF-7细胞凋亡。两者合计,数据表明4b是一种有前途的抗肿瘤药物,应考虑用于进一步的体内研究。
