A new series of 1,2,4-triazole-linked urea and thiourea conjugates have been synthesized and evaluated for their in vitro cytotoxicity against selected human cancer cell lines namely, breast (MCF-7, MDA-MB-231), lung (A549) prostate (DU145) and one mouse melanoma (B16-F10) cell line and compared with reference drug. The compound 5t showed significant cytotoxicity on MCF-7 breast cancer cell line with a IC value of 7.22 ± 0.47 µM among all the tested compounds. Notably, induction of apoptosis by compound 5t on MCF-7 cells was evaluated using different staining techniques such as acridine orange/ethidium bromide (AO/EB), annexin V-FITC/PI, and DAPI. Further, clonogenic assay indicates the inhibition of colony formation on MCF-7 cells by compound 5t. Moreover, the flow-cytometric analysis also revealed that compound 5t caused the arrest of cells at G0/G1 phase of cell cycle. In addition, the compounds when tested on normal human cells (L-132) were found to be safer with low cytotoxicity profile.
已合成了一系列新的 1,2,4-三唑连接的脲和硫脲缀合物，并对其进行了体外细胞毒性评估，针对的是选定的人类癌细胞系，包括乳腺癌（MCF-7、MDA-MB-231）、肺癌（A549）、前列腺癌（DU145）和一种小鼠黑色素瘤（B16-F10）细胞系，并与参比药物进行了比较。在所有测试的化合物中，化合物 5t 对 MCF-7 乳腺癌细胞系表现出显著的细胞毒性，IC 值为 7.22±0.47µM。值得注意的是，通过不同的染色技术，如吖啶橙/溴化乙锭（AO/EB）、Annexin V-FITC/PI 和 DAPI，评估了化合物 5t 对 MCF-7 细胞的凋亡诱导作用。此外，集落形成抑制试验表明，化合物 5t 抑制 MCF-7 细胞的集落形成。此外，流式细胞术分析还表明，化合物 5t 导致细胞周期停滞在 G0/G1 期。此外，当在正常人类细胞（L-132）上进行测试时，这些化合物被发现具有较低的细胞毒性特征，安全性更高。
