Synthesis of 3-(4-((3-Phenyl-4,5-dihydroisoxazol-5-yl)methyl)piperazin-1-yl) benzoisothiazole derivatives (5a-i), which constitute a new class of isoxazolines, has been accomplished in regio-selective manner. These derivatives have been prepared by employing the reaction between substituted aldoximes (4a-i) and 3-(4-Allylpiperazin-1-yl) benzoisothiazole in presence of chloramine-T which afforded in
已经完成了构成新型异恶唑啉的3-(4-((3-苯基-4,5-二氢异恶唑-5-基)甲基)哌嗪-1-基)苯并异噻唑衍生物(5a-i)的合成以区域选择性的方式。这些衍生物是通过在氯胺-T存在下利用取代的醛肟(4a-i)和3-(4-烯丙基哌嗪-1-基)苯并异噻唑之间的反应制备的,其收率很高。筛选这些化合物对肿瘤细胞的细胞毒活性。与哺乳动物癌细胞中与肿瘤坏死因子相关的凋亡诱导配体(TRAIL)蛋白相比,九种合成化合物中的四种被发现具有强大的细胞毒性和抗肿瘤活性。其余的衍生物显示中等活性。
