Netropsin (dihydrochloride) is a small-molecule MGB (minor-groove binder), inhibits the catalytic activity of isolated topoisomerase and interferes with the stabilization of the cleavable complexes of topoisomerase II and I in nuclei[1]. Netropsin (dihydrochloride) has potential antibiotic and antiviral properties by binding to dsDNA in a non-intercalative manner, it improves survival from murine endotoxaemia by attenuating NOS2 induction through interference with HMGA1 DNA binding to the core NOS2 promoter[2]. Netropsin (dihydrochloride) in solutions of DNA has radioprotective ability against radiation-induced damage due to its high binding affinity and high structural stabilization, hydroxyl radical (OH*) generated by ionizing radiation cannot radiolyse the netropsin-DNA complex[3].
