Pharmaceutical drug development frequently involves the use of complexation to modify the pharmacological, toxicological, and physico-chemical properties of drugs. In our investigation, we employed solvent-free (mechanochemical) synthesis techniques to create copper (II) and silver (I) complexes with cefuroxime. Various physico-chemical analyses, including infrared spectroscopy, UV/Visible spectroscopy, elemental analysis, melting point determination, solubility tests, and conductivity measurements, were utilized to characterize these complexes. Our findings led to the proposed chemical formulas of [Cu(CFU)2H2O] and [Ag(CFU)NO3], where CFU represents cefuroxime. To assess the antimicrobial activity of the synthesized complexes, we conducted experiments using the disc diffusion method against a range of bacteria, including Streptococcus pneumonia, Bacillus subtillus, Salmonella typhi, Klebsiella pneumoniae, Escherichia coli, Methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, and Staphylococcus aureus. Our results demonstrated that these complexes exhibited superior antimicrobial activity compared to the free ligand. Analysis of the IR spectra indicated that cefuroxime coordinated with the metal ions through v(COO), v(C=O), and the oxygen atom of the water molecule. Moreover, distinct differences in the melting point, color, and electronic spectra of the complexes in comparison to the ligand strongly suggest the formation of coordination compounds.
