cytotoxicity studies were carried out on melanoma cell line WM35 which confirm that both compounds inhibit the growth of these cells. They have a higher activity compared to a platinum drug, carboplatin. A new N-sulfonamide ligand (HL1= N-(5-(4-methoxyphenyl)-[1,3,4]–thiadiazole–2-yl)-toluenesulfonamide) and two Cu(II) complexes, [Cu(L1) 2 (py) 2 ] and [Cu(L2) 2 (py) 2 (H 2 O)] (HL2= N-(5-(4-methylphenyl)-[1
一个新的N-磺酰胺配体(HL1 = N-(5-(4-甲氧基苯基)-[1,3,4]-噻二唑-2-基)-甲苯磺酰胺)和两个Cu(II)络合物[Cu(L1)2(py)2 ](C1)和[Cu(L2)2(py)2(H 2 O)](C2)(HL2 = N-(5-(4-甲基苯基)-[1,3,4] -噻二唑-2-基)-苯磺酰胺)。测定了配合物的X射线晶体结构。在配合物C1中,Cu(II)离子为四配位,形成CuN 4发色团;在配合物C2中,Cu(II)离子为五配位,形成CuN 4 O发色团。配体充当单齿,通过单个N噻二唑配位Cu(II)离子原子。反应介质中的分子(吡啶和水)也参与Cu(II)离子的配位。配合物C1和C2分别为方形平面和略微变形的方形锥体。通过FT-IR,电子,EPR光谱和磁性方法对化合物进行表征。合成复合物的核酸酶结合活性研究证实了它们裂解DNA分子的能力。在黑色素瘤细胞系WM35上进行了细
