Antibacterial behavior of chitosan-bivalent metal chelates (Co and Ni) was investigated in vitro against standard bacteria, Staphylococcus aureus ATCC 4533, S. faecalis ATCC 8043 and Escherichia coli ATCC 25923. The chitosan-metal chelates were prepared by varying the molar ratio of metal ions to a fixed amount of chitosan. The metal ion contents,(More)
Chemical reduction of nitrate using metal nanoparticles has received increasing interest due to over-dependence on groundwater and consequence health hazard of the nitrate ion. One major drawback of this technique is the agglomeration of nanoparticles leading to the formation of large flocs. A low cost biopolymeric material, poly(More)
Metal coordination of bioorganic compounds from both natural and synthetic products is not only gaining recognition in drug design and medicinal inorganic chemistry research, also they are being considered in the improvement of the bioactivity of drugs. What is done in this paper is a review of recent advances in the study of coordination-driven drug(More)
A range of transition metals ligated by sesquiterpene lactone-artesunate (ATS) have been investigated. Syntheses of Cu(II), Ni(II), and Mn(II) complexes of decahydro-3,6,9-trimethyl3,12-epoxy-12H-pyrano[4,3-j]1,2-benzodioxepin10-ol hydrogen succinate were prepared by a direct aqueous substitution reaction in methanol. Structural elucidations of the(More)
