The reactions of dicyclopentadienylzirconium(IV) dichloride with picolinoyl, nicotinoyl and isonicotinoyl hydrazones derived from the appropriate acid hydrazides and acetone, acetophenone, salicylaldehyde or o-hydroxyacetophenone, have been studied in anhydrous tetrahydrofuran or dichloromethane in the presence or absence of amine using different molar ratios. Tentative structural coclusions are drawn
在无水四氢呋喃或二氯甲烷中,在存在或不存在胺的情况下,研究了无水四氢呋喃或二氯甲烷中二环戊二烯基二氯化锆(IV)与衍生自适当酸酰肼和丙酮,苯乙酮,水杨醛或邻羟基苯乙酮的吡啶甲酸,烟碱和异烟酰肼的反应。比率。根据元素分析,电导率,磁矩和光谱数据(电子,红外和1 H NMR)为反应产物绘制了暂定的结构共轭关系。这些配体表现为中性或去质子化的螯合剂。配位行为取决于介质的pH,取代基的性质以及hydr基相对于吡啶氮核的位置。

Co(II), Mn(II), oxovanadium(IV), oxovanadium(V) and Pd(II) complexes have been prepared and their stereochemistries identified. Flexidentate behaviour of these ligands have also been examined. Under different reaction conditions, the ligands exhibit neutral, monobasic and dibasic tridentate character. Models throw light on the mode of attachment of the ligands to the metal ions.

A systematically generated series of hydrazones were analyzed as potential inhibitors of anthrax lethal factor. The hydrazones were screened using one UV-based and two fluorescence-based in vitro assays. The study identified several inhibitors with IC50 values in the micromolar range, and importantly, significant differences in the types of inhibition were observed with the different assays.
