Two series of tetrazole-containing platinum(II) and palladium(II) chlorido complexes, trans-[ML2Cl2] (M = Pt, Pd) and cis-[PtL2Cl2]·nH2O (n = 0, 1), where L is 1- or 2-substituted 5-aminotetrazole, have been synthesized and thoroughly characterized. Configuration of platinum(II) complexes obtained from the reaction of 5-aminotetrazoles with K2PtCl4 has been found to vary depending on the nature of
两个系列的铂(II)和钯的含四唑(II)chlorido配合物,反式- [ML 2氯2 ](M =铂,钯)和顺式- [专利文献2氯2 ]· Ñ ħ 2 O(Ñ = (0,1),其中L是1-或2-取代的5-氨基四唑,已经合成并充分表征。已经发现,由5-氨基四唑与K 2 PtCl 4反应获得的铂(II)配合物的构型根据四唑衍生物的性质和反应条件而变化。根据体外在细胞毒性评估中,只有铂配合物显示出明显的抗增殖作用,并且它们的细胞毒性在很大程度上取决于其几何形状和载体配体的疏水性。最有前途的配合物是顺式-[Pt(1-apt)2 Cl 2 ]·H 2 O和顺式-[Pt(2-abt)2 Cl 2 ]·H 2 O,其中1-apt是5-氨基- 1-苯基四唑和2-abt是5-氨基-2-叔丁基四唑。与顺铂相比,它们对顺铂敏感的人类癌细胞系cis- [Pt(2-abt)2 Cl 2 ]·H 2具有可比的细胞毒
