suitable cell-based assay using resazurin reduction method, and evaluated towards cell cycle, apoptosis and Tax/GFP expression analyses through flow cytometry. Compound 02 induced S phase cell cycle arrest and compounds 05, 06, 22 and 25 promoted apoptosis. Remarkably, compounds 22 and 25 also reduced GFP expression in an inducible-tax reporter cell, which suggests an effect on Tax viral protein. More importantly
1型人类T细胞淋巴病毒(HTLV-1)是一种人类逆转录病毒,感染了全世界约10-20百万人,并引起侵袭性肿瘤(成人T细胞白血病/淋巴瘤-ATL)。治疗ATL的治疗方法疗效不一,预后差,因此需要策略来鉴定对感染细胞具有活性的新型化合物。从这个意义上讲,我们最初筛选了25个1,2,3-三唑衍生物的小系列,以发现HTLV-1感染的T细胞系(MT-2)中的细胞增殖抑制剂和凋亡诱导剂,以进一步评估其对TLV-1的作用。通过诱导税收报告细胞系(Jurkat LTR-GFP)进行病毒税收活动。八种有前途的化合物(02,05,06,13,15,21,22和25)具有活性的≥70%的最初选择的基础上,合适的基于细胞的刃天青使用还原法测定,并朝向细胞周期,细胞凋亡和税务/ GFP表达分析评价通过流式细胞仪。合成化合物02诱导的S期的细胞周期停滞和化合物05,06,22和25促进细胞凋亡。值得注意的是,化合物2
