compounds, 6d, 6e, and 8a–e, suppressed cancer cell growth (GI50 = 0.23–2.00 µM) comparably to erlotinib (GI50 = 0.06 µM). Compounds 6d, 6e, and 8a–e inhibited the epidermal growth factor receptor tyrosine kinase (EGFR-TK) at IC50 = 0.11–0.73 µM, compared to erlotinib (IC50 = 0.08 ± 0.04 µM). The apoptotic mechanism revealed that the most active hybrid 8d induced expression levels of caspase-3, caspase-9,
已经设计和合成了一系列带有不同药效基团的1,3,4-恶二唑-1,2,3-三唑杂化物。使用 MTT (3-(4,5-dimethylthiazol-2-yl)−2,5) 评估了它们对四种人类癌细胞系(Panc-1、MCF-7、HT-29 和 A-549)的抗增殖活性-二苯基溴化四唑)测定。初步活性测试表明,与厄洛替尼 (GI 50 = 0.06 µM) 相比,最活跃的化合物6d、6e和8a-e可抑制癌细胞生长 (GI 50 = 0.23-2.00 µM )。与厄洛替尼( IC _50 = 0.08 ± 0.04 µM)。凋亡机制表明,最活跃的杂交8d诱导人癌细胞系 Panc-1 中 caspase-3、caspase-9 和 cytochrome-c 的表达水平比多柔比星高 7.80 倍、19.30 倍和 13 倍。此外,8d使 Bax 水平比阿霉素增加 40 倍,同时 Bcl-2 水平降低
