This research aimed to evaluate the potential of iodinated hydrazide-hydrazones and their analogues as dual antimicrobial and cytotoxic agents, addressing the increasing resistance of bacterial and fungal pathogens to existing treatments. The study synthesized and screened twenty-two iodinated hydrazide-hydrazones and ten 1,2-diacylhydrazines, along with their three reduced analogues, for their antibacterial, antifungal, and cytotoxic properties. The compounds were tested against eight bacterial and eight fungal strains, and their cytotoxicity was assessed on HepG2 and HK-2 cell lines. The study found that certain derivatives, particularly those containing the 3,5-diiodosalicylidene scaffold, exhibited potent antibacterial activity against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), with low minimum inhibitory concentrations (MIC) values. Some compounds also showed antifungal activity and variable degrees of cytotoxicity, with normal human cells exhibiting lower sensitivity. The research concluded that these compounds, especially those with electron-withdrawing groups like F, Cl, CF3, and NO2, have potential as antimicrobial and cytotoxic agents. The chemicals used in the process included various substituted benzohydrazides, 2-/4-hydroxy-3,5-diiodobenzaldehydes, 3,5-diiodosalicylic acid, and their derivatives, as well as reagents for biological assays and cytotoxicity tests.
