Roles Classification
Chemical Role(s): radical scavenger
A role played by a substance that can react readily with, and thereby eliminate, radicals.
A ligand with two or more separate binding sites that can bind to a single metallic central atom, forming a chelate.
A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.
Biological Role(s): plant metabolite
Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.
EC [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
Any compound produced by a plant that happens to have estrogenic activity.
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).
antibacterial agent
A substance 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.
Application(s): antineoplastic agent
A substance that inhibits or prevents the proliferation of neoplasms.
