    Due to the increasing threat of antibiotic resistance and the emergence of new pathogenic strains, the development of effective combined therapeutic agents represents a crucial direction in the fight against infections. Within this study, several compounds were synthesized in which iodine is present in a coordination complex with antibiotics—sodium sulfadimidine and gentamicin sulfate. The physicochemical parameters of these compounds were investigated using capillary electrophoresis and UV spectroscopy, along with their cytotoxicity, antimicrobial, and antiviral activities. As a result of this work, two stable compounds, KC-246 and KC-248, were synthesized, demonstrating virus-inhibitory activity against herpes simplex virus and influenza A under extremely low cytotoxicity levels of 0.018–0.106 mg/mL. Additionally, they exhibited antimicrobial activity against representatives of the families Staphylococcaceae, Pseudomonadaceae, Enterobacteriaceae, Enterococcaceae, and yeast-like fungi. The minimum bactericidal concentrations (MBCs) ranged from 0.794 µg/mL to 0.198 µg/mL (KC-246) and from 2.093 µg/mL to 0.523 µg/mL (KC-248).

    Iodine-based antimicrobial materials are widely considered for biomedical applications due to their broad-spectrum antimicrobial activity; however, their potential genotoxicity requires systematic evaluation prior to clinical use. The aim of this study was to assess the genotoxic potential of a dextrin–polyvinyl alcohol–iodine (D/PVA/I-1) complex in accordance with OECD guidelines. Genotoxicity was evaluated in vitro using two complementary assays: the mammalian cell micronucleus test (OECD TG 487) in L5178Y TK+/− cells and the bacterial reverse mutation assay (Ames test, OECD TG 471) using Salmonella typhimurium strains TA98, TA100, TA1535, TA1537 and Escherichia coli WP2 uvrA, both in the presence and absence of metabolic activation (S9). In the micronucleus assay, no statistically significant increase in micronucleus frequency was observed at concentrations ranging from 0.039 to 0.625 mg/mL compared with the negative control. In the Ames test, no increase in revertant colony numbers was detected in any tested bacterial strain at concentrations up to 1250 μg/plate. At higher concentrations, pronounced cytotoxic and bactericidal effects were observed without evidence of mutagenic activity. Overall, the results demonstrate that the D/PVA/I-1 complex does not exhibit genotoxic or mutagenic potential under the tested in vitro conditions, indicating a favorable genetic safety profile and supporting further preclinical evaluation for potential biomedical applications.
