NCIt definition : An orally bioavailable bis-dioxopiperazine and a derivative of the chelating agent
ethylenediaminetetraacetic acid (EDTA) with antineoplastic, antiangiogenic, and antimetastatic
activities. Razoxane specifically inhibits the enzyme topoisomerase II without inducing
DNA strand breaks, which may result in the inhibition of DNA synthesis and cell division
in the premitotic and early mitotic phases of the cell cycle. This agent may also
exhibit antiangiogenic and antimetastatic activities although the precise molecular
mechanisms of these actions are unknown.;
