Roles Classification
Chemical Roles:
radical scavenger  A role played by a substance that can react readily with, and thereby eliminate, radicals.
chelator  A ligand with two or more separate binding sites that can bind to a single metallic central atom, forming a chelate.
antioxidant  A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.
Biological Roles:
anti-obesity agent  Any substance which is used to reduce or control weight.
plant metabolite  Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.
EC 1.10.99.2 [ribosyldihydronicotinamide dehydrogenase (quinone)] inhibitor  An EC 1.10.99.* (oxidoreductases acting on diphenols and related substances as donors, other acceptors) inhibitor that interferes with the action of ribosyldihydronicotinamide dehydrogenase (quinone), EC 1.10.99.2.
antiviral agent  A substance that destroys or inhibits replication of viruses.
Aurora kinase inhibitor  Any protein kinase inhibitor that inhibits the action of an Aurora kinase (a group of serine/threonine kinases that are essential for cell proliferation).
phytoestrogen  Any compound produced by a plant that happens to have estrogenic activity.
antibacterial agent  A substance (or active part thereof) that kills or slows the growth of bacteria.
protein kinase inhibitor  An EC 2.7.* (P-containing group transferase) inhibitor that interferes with the action of protein kinases.
Applications:
ophthalmology drug  Any compound used for the treatment of eye conditions or eye diseases.
anti-inflammatory agent  Any compound that has anti-inflammatory effects.
hypoglycemic agent  A drug which lowers the blood glucose level.
antineoplastic agent  A substance that inhibits or prevents the proliferation of neoplasms.
geroprotector  Any compound that supports healthy aging, slows the biological aging process, or extends lifespan.
cardiovascular drug  A drug that affects the rate or intensity of cardiac contraction, blood vessel diameter or blood volume.
antifibrotic agent  Any agent which acts to reduce fibrosis.
anti-anaemic agent  A compound which increases either the number of red cells or the amount of haemoglobin in the blood.
