Roles Classification
Chemical Roles:
radical scavenger  A role played by a substance that can react readily with, and thereby eliminate, radicals.
antioxidant  A substance that opposes oxidation or inhibits reactions brought about by dioxygen or peroxides.
Bronsted acid  A molecular entity capable of donating a hydron to an acceptor (Brønsted base).
Biological Roles:
human metabolite  Any mammalian metabolite produced during a metabolic reaction in humans (Homo sapiens).
ferroptosis inhibitor  Any substance that inhibits the process of ferroptosis (a type of programmed cell death dependent on iron and characterized by the accumulation of lipid peroxides) in organisms.
antiviral drug  A substance used in the prophylaxis or therapy of virus diseases.
Applications:
antidote to paracetamol poisoning  A role borne by a molecule that acts to counteract or neutralize the deleterious effects of paracetamol (acetaminophen).
antiinfective agent  A substance used in the prophylaxis or therapy of infectious diseases.
antiviral drug  A substance used in the prophylaxis or therapy of virus diseases.
mucolytic  A compound that alters the structure of mucus so as to decrease its viscosity and thereby facilitate its removal by ciliary action and expectoration. Compare with antitussives, which suppress the cough reflex, and expectorants, which are considered to increase the volume of secretions in the respiratory tract, so facilitating their removal by ciliary action and coughing.
vulnerary  A drug used in treating and healing of wounds.
geroprotector  Any compound that supports healthy aging, slows the biological aging process, or extends lifespan.
