ChEBI

A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.

Any EC 1.14.18.* (oxidoreductase acting on paired donors, miscellaneous compound as one donor, incorporating 1 atom of oxygen) inhibitor that interferes with the action of tyrosinase (monophenol monooxygenase), EC 1.14.18.1, an enzyme that catalyses the oxidation of phenols (such as tyrosine) and is widespread in plants and animals.

An EC 2.3.1.* (acyltransferase transferring other than amino-acyl group) inhibitor that interferes with the action of arylamine N-acetyltransferase (EC 2.3.1.5).

Any EC 2.4.1.* (hexosyltransferase) inhibitor that interferes with the action of glycogen phosphorylase (EC 2.4.1.1).

An EC 2.5.1.* (non-methyl-alkyl or aryl transferase) inhibitor that interferes with the action of a glutathione transferase (EC 2.5.1.18).

Any EC 2.7.1.* (phosphotransferases with an alcohol group as acceptor) inhibitor that interferes with the action of inositol-trisphosphate 3-kinase (EC 2.7.1.127).

Any EC 2.7.1.* (phosphotransferases with an alcohol group as acceptor) inhibitor that interferes with the action of inositol-polyphosphate multikinase (EC 2.7.1.151).

Any EC 2.7.4.* (phosphotransferases with a phosphate group as acceptor) inhibitor that interferes with the action of nucleoside-diphosphate kinase (EC 2.7.4.6).

Any substance which is added to food to preserve or enhance its flavour and/or appearance.

Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.

A topoisomerase inhibitor that inhibits the bacterial enzymes of the DNA topoisomerases, Type I class (EC 5.99.1.2) that catalyze ATP-independent breakage of one of the two strands of DNA, passage of the unbroken strand through the break, and rejoining of the broken strand. These bacterial enzymes reduce the topological stress in the DNA structure by relaxing negatively, but not positively, supercoiled DNA.

A topoisomerase inhibitor that inhibits DNA topoisomerase (ATP-hydrolysing), EC 5.99.1.3 (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.

A DNA polymerase inhibitor that interferes with the action of a DNA-directed DNA polymerase (EC 2.7.7.7).

Any eukaryotic metabolite produced during a metabolic reaction in fungi, the kingdom that includes microorganisms such as the yeasts and moulds.

Any substance which is added to food to preserve or enhance its flavour and/or appearance.

Any cosmetic used to lighten the colour of skin by reducing the concentration of melanin.

Any compound that supports healthy aging, slows the biological aging process, or extends lifespan.
