Structural elucidation and biological significance of 2-hydroxy-1-naphthaldehyde derived sulfonamides and their first row d-transition metal chelates.
2-Hydroxy-1-naphthaldehyde derived sulfonamides and their first row d-transition metal chelates [cobalt (II), copper (II), nickel (II) and zinc (II)] have been synthesized and characterized. The nature of bonding and structure of all the compounds have been deduced from elemental analyses, infrared, 1H NMR, 13C NMR, mass spectrometry, electronic spectra, magnetic susceptibility and conductivity measurements. An octahedral geometry has been suggested for all the complexes. The metal complexes were screened for their antibacterial and antifungal activities on different species of pathogenic bacteria and fungi and their biopotency has been discussed. The results of these studies revealed that all compounds showed moderate to significant antibacterial activity against all bacterial strains and good antifungal activity against various fungal strains. In-vitro cytotoxic properties of all the compounds against Artemia salina was also studies by brine shrimp bioassay.
