respectively in comparison to sildenafil (IC50 0.689 nM). Moreover, compounds 3a, 3c, 3f, 3g, 3h were found to have potent cytotoxic activities against MCF-7 cancer cell line with IC50 ranging from 5.47±0.4 to 9.92±0.9 µM. Apoptosis cytometric assay showed that compound 5a induced pronounced increase in the total percent of apoptotic HCT116 cells (15.87%) compared to 3c (12.43%), mainly during late stage
抑制磷酸二酯酶 5 (PDE5) 已被证实为可能的癌症新治疗方法。为了进一步探索这一概念,设计并合成了三个系列的含有噻唑并嘧啶的化合物作为 PDE5 抑制剂。除了对三种不同癌细胞系(结肠直肠癌结肠癌;HCT-116,乳腺乳腺癌;MCF-7 和人前列腺癌;PC3)的抗增殖活性外,还评估了所有化合物对 PDE5 的抑制作用。细胞系(人肺成纤维细胞;WI38)。在合成的化合物中,三种化合物(3c、4a 和 5a)显着抑制 PDE5,IC 50分别为 0.046 nM、0.323 nM 和 0.546 nM,与西地那非(IC 500.689 纳米)。此外,化合物3a、3c、3f、3g、3h对 MCF-7 癌细胞系具有有效的细胞毒活性,IC 50范围为 5.47±0.4 至 9.92±0.9 µM。细胞凋亡细胞计数分析表明,与3c (12.43%) 相比,化合物5a诱导的凋亡 HCT116 细胞的总百分比
