摘要

Coordination complexes exhibited interesting potentials in different fields such as medical, industrial, pharmaceutical, and analytical. They possess versatile biological applications in drugs synthesis, extraction of noble metals like silver and gold from their ores and in metals purification. In current project we aim to synthesized and characterized transition metal complexes like Mn, Fe, Co, Ni, Cu and Zn using Nitroso-R Salt as a ligand. This study presents a novel approach to develop stable metal complexes using Nitroso R Salt, a ligand comprising nitrosyl, hydroxyl, and sulfonate groups. This study offers a combined analysis of both chemical and functional properties, which was not commonly investigated with NRS, by combining biological screening with thorough structural characterizations (FTIR, CHN, XRD and UV). The complexes were then subjected to various tests to explore their deoxyribose degradation inhibition potential, antioxidant and antimicrobial potential. Copper and Zinc Complexes showed good potential 173 and 182% against iron at 100 mM. The highest potential was recorded for Nickel complex potential 2, 7 and 14% against H2O2, Fe (II) and in combine form. It was further confirmed respectively by antioxidant DPPH assay. Ligand and complexes showed good inhibitory potential by showing 18.66, 39.32, 38.22, 28.89, 20.71, 19.14 and 28.89% for NRS, Iron, Cobalt, Nickel, Zinc, Copper and Manganese complexes at high concentration of 200uM, respectively. The complexes showed promising antibacterial and antioxidant properties. Nickel complexes demonstrated a strong inhibition against reactive species, but copper and zinc complexes showed a notably high antioxidant capacity. Effective inhibitory zones were found in antimicrobial testing, especially for Fe, Mn, Co, and Cu complexes against Klebsiella pneumoniae and Bacillus subtilis. However, further studies are needed to examine the exact mechanisms of action of these discoveries, which point to possible biomedical uses.
