involved in regulation of serum uric acid, xanthine oxidase (XO) is the best pharmacological target to control the levels of serum uric acid as it catalyzes the final steps in uric acid production. In the current study, a systemic search for the inhibitors of xanthine oxidase, starting from synthesis to in vitro screening and leading to in vivostudies is presented.

oxovanadium and dioxomolybdenum Schiffbasecomplexes, [VO(L)(OCH3)]n and [MoO2(L)(CH3OH)], were synthesized by treating an ONO donorSchiffbase (H2L) derived by condensation of 3-ethoxysalicylaldehyde and nicotinic hydrazide with oxo and dioxo acetylacetonate salts of vanadium and molybdenum (VO(acac)2 and MoO2(acac)2), respectively. The synthesized ligand and complexes were characterized by FTIR, multinuclear
摘要 新的氧钒和二氧钼席夫碱配合物 [VO(L)(OCH 3 )] n和 [MoO 2 (L)(CH 3 OH)] 通过处理缩合得到的 ONO 供体席夫碱 (H 2 L)合成3-乙氧基水杨醛和烟碱酰肼分别与钒和钼的氧代和二氧代乙酰丙酮盐(VO(acac) 2和MoO 2 (acac) 2)。合成的配体和配合物通过 FTIR、多核 ( 1 H, 13C) NMR、元素和单晶 X 射线衍射分析。衍射研究表明,在这两种配合物中,中心金属离子周围的几何形状都是扭曲的八面体。合成化合物的理论计算采用DFT在B3LYP/Def2-TZVP理论水平下进行,与实验结果具有良好的相关性。此外,通过在乙醇中 30% H 2 O 2存在下氧化芳基和烷基硫化物来研究这两种配合物的催化效率。
