Roles Classification
Chemical Role(s): antioxidant
A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.
Biological Role(s): EC [DNA topoisomerase (ATP-hydrolysing)] inhibitor
A topoisomerase inhibitor that inhibits DNA topoisomerase (ATP-hydrolysing), EC (also known as topoisomerase II and as DNA gyrase), which catalyses ATP-dependent breakage of both strands of DNA, passage of the unbroken strands through the breaks, and rejoining of the broken strands.
Application(s): antineoplastic agent
A substance that inhibits or prevents the proliferation of neoplasms.
A compound that causes the contraction of body tissues, typically used to reduce bleeding from minor abrasions.
