Chrysin‐based sulfonylpiperazines 7a‐k were synthesized and investigated for their in vitro free radical scavenging potential as well as cytotoxic efficacies against selected cancer cell lines. Cytotoxicity of the new compounds toward noncancer cells was confirmed using the SRB assay against Madin–Darby Canine Kidney cells. Reaction of piperazine with different substituted benzenesulfonyl chlorides
合成了基于白杨素的磺酰基哌嗪 7a-k,并研究了它们的体外自由基清除能力以及对选定癌细胞系的细胞毒性作用。使用针对 Madin-Darby 犬肾细胞的 SRB 测定证实了新化合物对非癌细胞的细胞毒性。哌嗪与不同取代苯磺酰氯在三乙胺提供的磺酰哌嗪 (3a-k) 中反应,然后与 7-(4-溴丁氧基)-5-羟基-2-苯基-4H-色胺-4-酮 (6 ) 制备白杨素与 1,4-二溴丁烷反应得到最终衍生物 7a-k。结果表明,白杨素-磺酰基哌嗪比以前研究的白杨素-哌嗪前体具有更好的抗氧化和抗癌功效。例如,化合物 7h、7j 和 7k 与 4-OCF3、4-OCH3、和 2,4-diOCH3 基团对 2,2-diphenyl-1-picrylhydrazyl (DPPH) 和 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) 自由基
