A novel application of radiomimetic compounds as antibiotic drugs.

Objective: This study aims to examine the potential of radiomimetic compounds as antimicrobial therapeutics, as the recent advances in radiomimetic targeting as well as rapid increase of multidrug resistant bacteria make these compounds attractive for future development.

Methods: Representative radiomimetics from each of the three major categories was examined; C-1027 and neocarzinostatin from the protein-chromophore enediyne family; Calicheamicin from the non-protein chromophore enediyne family and Bleomycin and Tallysomycin S10b from the glycopeptide family. The activity of these compounds was examined against 12 distinct bacteria species.
