l)-2-hydroxyiminoacetic acid (anti-A and syn-A respectively) were used as potential biologically active polydentate complexing agent for Co2+, Ni2+, Cu2+ and Pd2+ ions for the synthesis of novel complex compounds with directed angiogenesis-correcting action. It shown that the location of functional groups in ligand molecules, the electronic structure of metal as complexing agent and the synthesis conditions
摘要使用2-(2-氨基噻唑-4-基)-2-羟基亚氨基乙酸的反异构体和同分异构体(分别为抗A和Syn-A)作为潜在的具有生物活性的Co2 +,Ni2 +,Cu2 +和D2的多齿络合剂。 Pd2 +离子用于合成具有定向血管生成校正作用的新型复合化合物。结果表明,配体分子中官能团的位置,金属作为络合剂的电子结构以及合成条件影响配位键的位置和形成的配合物的结构。金属盐的乙醇溶液与抗A和合成A在酸性介质中以M:L = 1:1和1:2的组分比相互作用导致形成配合物[Co(anti-A)(H2O) )3SO4](1);[Ni(anti-A)(H2O)3SO4](2); [Cu(抗-A)2Cl2](3); [Pd(抗-A)2Cl2](4); [Cu(syn-A)2Cl2](5); [Pd(syn-A)Cl2](6)具有不同的配体配位。通过IR,UV-Vis,XPS和1H(13C)NMR光谱鉴定的配体配位模
