    SCREENING OF BIOLOGICAL PROPERTIES OF MOV2O2S2- AND MOV2O4-BASED COORDINATION COMPLEXES: INVESTIGATION OF ANTIBACTERIAL, ANTIFUNGAL, ANTIOXIDATIVE AND ANTITUMORAL ACTIVITIES VERSUS GROWING OF SPIRULINA PLATENSIS BIOMASS

    This paper deals with the biological potential of coordination compounds based on binuclear core [MoV2O2E2]2+ (E = O or S) coordinated with commercially available ligands such as oxalates (Ox2−), L-cysteine (L-cys2−), L-histidine (L-his−), Iminodiacetate (IDA2−), Nitrilotriacetate (HNTA2− or NTA3−) or ethylenediamine tetraacetate (EDTA4−) by means of various in vitro assays in a screening approach. Results suggest that the obtained complexes show weak antibacterial and antifungal properties while not being cytotoxic on cancerous and mammalian cells. In contrast, [Mo2O2E2(L-cys)2]2− complexes stand out as powerful antioxidant, whereas [Mo2O2E2(EDTA)]2− associating tetraphenylphosphonium counter-cations display strong antibiotic activity. Finally, some complexes have evidenced a positive activity towards the growing of spirulina platensis together with a modification of the proportions of biological components inside the cells. These findings reveal promising bioactivity of the bridged binuclear Mo(+V) cores inside complexes and encourage further research for new highly active yet non-toxic molecules for biological and biomedical applications.
