o-nitrobenzoyl-, salicyloyl- and isonicotinoyl hydrazines have been synthesised by condensing acetylferrocene and/or formylferrocene with the respective aroyl hydrazine. These organometallic compounds act as ligands for metal complexation and copper(II) complexes of some of these have been isolated and characterized.

A series of ferrocenyl hydrazones and their beta-cyclodextrin (CD) inclusion complexes were prepared and evaluated for antitubercular activity under low and high iron conditions. The inclusion complexes were characterized by Fourier Transform Infrared (FTIR), Differential Scanning Calorimetry (DSC), Powder X-ray Diffraction (PXRD), H-1 NMR, Scanning Electron Microscopy (SEM) and Cyclic Voltammetric (CV) studies. The inclusion complexes exhibited improved aqueous solubility as well as enhanced hydrolytic and thermal stability. They were also found to exhibit greater antitubercular activity than the parent ferrocenyl hydrazones against Mycobacterium tuberculosis under high iron conditions. When grown under low iron conditions these compounds exhibited lower activity suggesting requirement of iron-dependant peroxidase activation. (C) 2014 Elsevier Ltd. All rights reserved.
