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. Benzylidene nicotino/isonicotinohydrazides
A library of acylhydrazone iron chelators was synthesized and tested for its ability to inhibit the growth of a chloroquine-resistant strain of Plasmodium falciparum. Some of these new compounds are significantly more active than desferrioxamine DFO, the iron chelator in widespread clinical use and also than the most effective chelators. (c) 2005 Elsevier Ltd.

Experimental and theoretical studies of new dioxomolybdenum complex: Synthesis, characterization and application as an efficient homogeneous catalyst for the selective sulfoxidation
with titanium (III) chloride and (IV) bromide and 12 novel complexes were synthesized and studied experimentally and theoretically. Using the UV–vis spectroscopic titration, the solution stability of the complexes was indicated. Depending on the nature of the Schiffbase ligand, their formation constants were calculated in the range of 6.84–17.32. Using the DFT def2-TZVP theoretical method together
dinuclear bismuth(III) Schiff-base complexes bearing Schiff-base ligands have been synthesized and structurally characterized by single-crystal X-ray diffraction, elemental analysis, and spectral techniques (FT-IR, NMR and MS). The analytical data reveal the bismuth(III) complexes possess 1:1 metal–ligand ratios. In vitro biological studies have revealed that bismuth(III) complexes displayed much higher
合成了四种带有席夫碱配体的双核铋 (III) 席夫碱配合物,并通过单晶 X 射线衍射、元素分析和光谱技术(FT-IR、NMR 和 MS)对其结构进行了表征。分析数据表明,铋 (III) 配合物具有 1:1 的金属配体比。体外生物学研究表明,铋 (III) 配合物显示出比其母体配体更高的抗菌和抗肿瘤活性,其中涉及两种革兰氏阴性菌(金黄色葡萄球菌、枯草芽孢杆菌)和两种革兰氏阳性菌(大肠杆菌、P . aeruginosa ) 细菌和人胃癌 SNU-16 细胞。S. pombe的功率-时间曲线通过生物微量热法检测暴露于测试化合物的。根据代谢功率-时间曲线导出了一些热动力学参数(k、P max、 t G和Q total ),并进一步讨论了它们与浓度( c )的定量关系。
