e (HL 4) (cltrz). Subsequently, oxovanadium(IV) complexes of the type [VO(saltrz)2] (1), [VO(dhtrz)2] (2), [VO(ndtrz)2] (3), and [VO(cltrz)2] (4) were synthesized by the reactions of vanadyl(V) isopropoxide [VO(OCHMe2)3] with the ligands HL 1–HL 4. The synthesized compounds were characterized by the melting point method, elemental analysis, FT-IR and 1H and 13C NMR spectroscopies, the molar susceptibility
通过将4H-1,2,4-三唑-4-胺与水杨醛(HL 1)(saltrz),2,3-二羟基苯甲醛(HL 2)(dhtrz),2-缩合衍生化一系列新的甲亚胺前体羟基-1-萘醛(HL 3)(ndtrz)和5-氯-2-羟基苯甲醛(HL 4)(cltrz)。随后,[VO(saltrz)2 ](1),[VO(dhtrz)2 ](2),[VO(ndtrz)2 ](3)和[VO(cltrz)2 ](4)是通过异丙氧基钒(V)[VO(OCHMe2)3 ]与配体HL 1 - HL 4。通过熔点法,元素分析,FT-IR和1H和13 C NMR光谱,摩尔磁化率和电导率方法以及热重分析法对合成的化合物进行了表征。配体HL 3和HL 4还通过单晶分析表征。SS-DNA与化合物的结合模式已通过低色度和UV-Vis光谱的红/蓝位移证实。化合物-DNA加合物的DG负值表明结合是自发过程。发现该复合物是酶碱性磷酸酶(ALP)
