Roles Classification
Chemical Role(s): ligand
Any molecule or ion capable of binding to a central metal atom to form coordination complexes.
radical scavenger
A role played by a substance that can react readily with, and thereby eliminate, radicals.
iron chelator

Biological Role(s): EC 1.1.1.21 (aldehyde reductase) inhibitor
An EC 1.1.1.* (oxidoreductase acting on donor CH-OH group, NAD+ or NADP+ acceptor) inhibitor that interferes with the action of aldehyde reductase (EC 1.1.1.21).
EC 1.1.1.25 (shikimate dehydrogenase) inhibitor
An EC 1.1.1.* (oxidoreductase acting on donor CH-OH group, NAD+ or NADP+ acceptor) inhibitor that interferes with the action of shikimate dehydrogenase (EC 1.1.1.25).
EC 1.1.1.205 (IMP dehydrogenase) inhibitor
An EC 1.1.1.* (oxidoreductase acting on donor CH-OH group, NAD+ or NADP+ acceptor) inhibitor that interferes with the action of IMP dehydrogenase (EC 1.1.1.205), so blocking de novo biosynthesis of purine nucleotides.
EC 1.6.5.2 [NAD(P)H dehydrogenase (quinone)] inhibitor
An EC 1.6.5.* (oxidoreductase acting on NADH or NADPH with a quinone or similar as acceptor) inhibitor that interferes with the action of NAD(P)H dehydrogenase (quinone), EC 1.6.5.2.
EC 1.8.1.9 (thioredoxin reductase) inhibitor
An EC 1.8.1.* (oxidoreductase acting on sulfur group of donors, NAD+ or NADP+ as acceptor) inhibitor that interferes with the action of thioredoxin reductase (EC 1.8.1.9).
flavouring agent
A food additive that is used to added improve the taste or odour of a food.
biological pigment
An endogenous molecular entity that results in a colour of an organism as the consequence of the selective absorption of light.
antifungal agent
An antimicrobial agent that destroys fungi by suppressing their ability to grow or reproduce.
lipoxygenase inhibitor
A compound or agent that combines with lipoxygenase and thereby prevents its substrate-enzyme combination with arachidonic acid and the formation of the icosanoid products hydroxyicosatetraenoic acid and various leukotrienes.
EC 3.5.1.98 (histone deacetylase) inhibitor
An EC 3.5.1.* (non-peptide linear amide C-N hydrolase) inhibitor that interferes with the function of histone deacetylase (EC 3.5.1.98).
immunomodulator
Biologically active substance whose activity affects or plays a role in the functioning of the immune system.
food colouring
A food additive that imparts colour to food. In European countries, E-numbers for permitted food colours are from E 100 to E 199, divided into yellows (E 100-109), oranges (E 110-119), reds (E 120-129), blues and violets (E 130-139), greens (E 140-149), browns and blacks (E 150-159), and others (E 160-199).
EC 2.7.10.2 (non-specific protein-tyrosine kinase) inhibitor
An EC 2.7.10.* (protein-tyrosine kinase) inhibitor that specifically blocks the action of non-specific protein-tyrosine kinase (EC 2.7.10.2).
metabolite
Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
plant metabolite
Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.
(via diarylheptanoid )
Application(s): hepatoprotective agent
Any compound that is able to prevent damage to the liver.
flavouring agent
A food additive that is used to added improve the taste or odour of a food.
nutraceutical
A product in capsule, tablet or liquid form that provide essential nutrients, such as a vitamin, an essential mineral, a protein, an herb, or similar nutritional substance.
dye

contraceptive drug
A chemical substance that prevents or reduces the probability of conception.
immunomodulator
Biologically active substance whose activity affects or plays a role in the functioning of the immune system.
neuroprotective agent
Any compound that can be used for the treatment of neurodegenerative disorders.
food colouring

In European countries, E-numbers for permitted food colours are from E 100 to E 199, divided into yellows (E 100-109), oranges (E 110-119), reds (E 120-129), blues and violets (E 130-139), greens (E 140-149), browns and blacks (E 150-159), and others (E 160-199).
anti-inflammatory agent
Any compound that has anti-inflammatory effects.
antineoplastic agent
A substance that inhibits or prevents the proliferation of neoplasms.
