... We offer access to a new class of synthetic antibiotics that target bacterial type II topoisomerase with a novel mode of action. There are several advantages of topoisomerase inhibitors as antibiotics. Bacteria contain the two type IIA topoisomerases DNA gyrase (topoisomerase II) and topoisomerase I ...
