and copper(I) complexes with modified amino acid esters and phosphine ligands have been prepared in order to test their cytotoxic activity. Two different phosphine fragments, PPh3 and PPh2py (py = pyridine), have been used. The amino acid esters have been modified by introducing an aromatic amine as pyridine that coordinates metal fragments through the nitrogen atom, giving complexes of the type [M(L)(PR3)]+
为了测试它们的细胞毒性活性,已经制备了具有修饰的氨基酸酯和膦配体的金(I),金(III),银(I)和铜(I)配合物。使用了两个不同的膦片段PPh 3和PPh 2 py(py =吡啶)。通过引入芳香胺作为吡啶来修饰氨基酸酯,吡啶可通过氮原子配位金属片段,从而形成[M(L)(PR 3)] +或[AuCl 3(L)]类型的络合物(L = 升-缬氨酸- N-(4-吡啶基羰基)甲基酯(L1),升丙氨酸-N-(4-吡啶基羰基)甲基酯(L2),升-苯丙氨酸-N-(4-吡啶基羰基)甲酯)(L3); M = Au(I),Ag(I),Cu(I),PR 3 = PPh 3,PPh 2 py)。在体外的金属配合物的细胞毒性活性对四名肿瘤人细胞系和一种肿瘤的小鼠细胞系测试。使用代谢活性测试(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四氮唑,MTT),并将IC 50值与顺铂的IC 50值进行比较。几种复
