derivatives via intramolecularoxidative coupling of thiosemicarbazide, using the in situ generated hypervalent iodine(III) reagents is developed. The protocol can be carried out smoothly and provides a variety of thiadiazole derivatives in moderate to excellent yields.Graphical AbstractA highly efficient method for the synthesis of thiadiazole derivatives via PhI-catalyzed intramolecularoxidative coupling

containing complexes have long been known to be well suited for biological applications, and have long been utilized as replacements to popular platinum based-drugs. Here, we report a novel series of ruthenium(II) arene compounds bearing thiosemicarbazone and isonicotinylhydrazone ligands with potent anticancer activity their structure activity relationships and apoptosis was studied. The cytotoxic activity
含铂化合物已显示出抗肿瘤潜力,但其临床应用受到高毒性的限制。长期以来,众所周知,含钌的配合物非常适合生物应用,并已长期用作流行的铂基药物的替代品。在这里,我们报告一系列新型的钌(II)芳烃化合物,带有硫代半脲和异烟酰ot配体,具有强大的抗癌活性,研究了它们的结构活性关系和细胞凋亡。新的钌(II)芳烃化合物的细胞毒活性已在几种细胞系(Molt 4 / C 8,L1210,CEM,HL60和BEL7402)中进行了评估。其中,有十种复合物在体外具有优异的表现IC 50在亚微摩尔范围内,对各种细胞系具有抑制生长的活性。
