Synthesis, physicochemical properties and antimicrobial activity of a di-aminopropionic acid hydrogen tri-iodide coordination compound. | LitMetric
Objective : The objective of this study is to synthesize and comprehensively characterize a novel iodine-containing coordination compound, di-aminopropionic acid hydrogen tri-iodide. This involves determining its structural, physicochemical, and thermal properties, as well as evaluating its antimicrobial activity against a range of bacterial strains, including multidrug-resistant pathogens. The aim is to explore the potential of this compound as a candidate for developing new antibacterial agents to address the challenge of antibiotic resistance.Results : An original iodine-containing semiorganic coordination compound was synthesized and characterized. The physicochemical properties were studied via diffraction, FTIR spectroscopy and thermogravimetric/differential scanning calorimetry (TG/DSC). In vitro antimicrobial activity evaluation was performed using two-fold serial dilution method. The obtained results demonstrated efficiency against both gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli, Pseudomonas aeruginosa, Acinetobacter baumannii) bacteria including MDR strains that cause infectious disease. The results of the antibacterial evaluation revealed that the new iodine coordination compound - di-aminopropionic acid hydrogen tri-iodide possesses high bactericidal properties and exhibits better antimicrobial activity against both susceptible and multidrug-resistant strains than does Lugol solution and ampicillin sodium, which are used as reference drugs.
