ChEBI

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

A molecular entity capable of donating a hydron to an acceptor (Bronsted base).

A molecular messenger in which the molecule is specifically involved in transmitting information between cells. Such molecules are released from the cell sending the signal, cross over the gap between cells by diffusion, and interact with specific receptors in another cell, triggering a response in that cell by activating a series of enzyme controlled reactions which lead to changes inside the cell.

An agonist that selectively binds to and activates a retinoid X receptor.

An antogonist that interferes with the action of activator protein 1 (AP-1).

An agonist that selectively binds to and activates a retinoic acid receptor.

Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).

Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.

Any vitamin that dissolves in fats and are stored in body tissues. Unlike the water-soluble vitamins, they are stored in the body for long periods of time and generally pose a greater risk for toxicity when consumed in excess.

A substance that inhibits or prevents the proliferation of neoplasms.

A drug that softens, separates, and causes desquamation of the cornified epithelium or horny layer of skin. Keratolytic drugs are used to expose mycelia of infecting fungi or to treat corns, warts, and certain other skin diseases.

Any compound that has anti-inflammatory effects.

An agonist that selectively binds to and activates a retinoic acid receptor.
