analogues-1,2,4-oxadiazole hybrid derivatives were synthesized by a new, simple, and efficient method using for the first time HAP-SO3H as an heterogenous acid catalyst for the condensation and cyclization between amidoxime and aldehyde. The new derivatives were characterized by HRMS, FT-IR, 1H NMR, and 13C NMR spectroscopy techniques. The synthesized 1,2,4-oxadiazole hybrids were evaluated for their cytotoxic
通过一种新的,简单而有效的方法合成了一系列新的尿嘧啶类似物-1,2,4-恶二唑杂化衍生物,首次使用HAP-SO 3 H作为异质酸催化剂,用于mid胺肟与and胺肟的缩合和环化。醛。通过HRMS,FT-IR,1 H NMR和13 C NMR光谱技术对新衍生物进行了表征。评估了合成的1,2,4-恶二唑杂种在五种人类癌细胞系中的细胞毒活性:黑素瘤(A-375),纤维肉瘤(HT-1080),乳腺(MCF-7和MDA-MB-231),和肺癌(A-549)。数据显示化合物22和23是针对HT-1080和MFC-7细胞的有效细胞毒性剂,IC 50低于1 µM。使用膜联蛋白V染色,caspase-3 / 7活性,线粒体膜电位测量和分析细胞周期进程,研究了由衍生物诱导的凋亡的可能机制。化合物22通过caspase-3 / 7激活和HT-1080和A549细胞的S期阻滞诱导细胞凋亡。分子对接表明化合物22通过
