DefinitionA morphinane alkaloid that is a highly potent opiate analgesic psychoactive drug. Morphine acts directly on the central nervous system (CNS) to relieve pain but has a high potential for addiction, with tolerance and both physical and psychological dependence developing rapidly. Morphine is the most abundant opiate found in Papaver somniferum (the opium poppy).

Roles Classification
Chemical Roles:
environmental contaminant  Any minor or unwanted substance introduced into the environment that can have undesired effects.
Bronsted base  A molecular entity capable of accepting a hydron from a donor (Brønsted acid).
Biological Roles:
mu-opioid receptor agonist  A compound that exhibits agonist activity at the μ-opioid receptor.
opioid analgesic  A narcotic or opioid substance, synthetic or semisynthetic agent producing profound analgesia, drowsiness, and changes in mood.
xenobiotic  A xenobiotic (Greek, xenos "foreign"; bios "life") is a compound that is foreign to a living organism. Principal xenobiotics include: drugs, carcinogens and various compounds that have been introduced into the environment by artificial means.
drug allergen  Any drug which causes the onset of an allergic reaction.
plant metabolite  Any eukaryotic metabolite produced during a metabolic reaction in plants, the kingdom that include flowering plants, conifers and other gymnosperms.
metabolite  Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
Applications:
geroprotector  Any compound that supports healthy aging, slows the biological aging process, or extends lifespan.
mu-opioid receptor agonist  A compound that exhibits agonist activity at the μ-opioid receptor.
opioid analgesic  A narcotic or opioid substance, synthetic or semisynthetic agent producing profound analgesia, drowsiness, and changes in mood.
drug allergen  Any drug which causes the onset of an allergic reaction.
vasodilator agent  A drug used to cause dilation of the blood vessels.
