ABSTRACT
The human digestive tract contains some 100 trillion cells and thousands of species of micro-organisms may be present as normal flora of this tract as well as other mucocutaneous junctions of the body. Candida specie is the most common organism residing in these areas and can easily invade the internal tissues in cases of loss of host defenses. Modifications of previously existing antifungal agents may provide new options to fight against these species. Inorganic compounds of different antifungals are under investigations. Present study report six complexes of fluconazole with Cu [II]], Fe[II], Cd[II], Co[II], Ni[II] and Mn[II] have been synthesized and characterized by elemental analysis, IR, UV and H-NMR. The elemental analysis and spectroscopic data were found in agreement with the expected values as the metal to ligand value was 1:2 ratios with two chlorides in coordination sphere. The morphology of each complex was studied using scanning electron microscope and compared with fluconazole molecule the flaky-slab rock like particles of pure fluconazole was also observed as reported earlier. However, the complexes of fluconazole were showed different morphology in their micrograph. Fluconazole and its complex derivatives have also been screened in vitro for their antifungal activity against Candida albican and Aspergillus niger by MIC method. The complexes showed varied activity ranging from 2-20%
