Bisnortilidine
Bisnortilidine is an opioid metabolite. It is formed from tilidine by demethylation Demethylation is the chemical process resulting in the removal of a methyl group (CH3) from a molecule. A common way of demethylation is the replacement of a methyl group by a hydrogen atom, resulting in a net loss of one carbon and two hydrogen at ... in the liver.

Tilidine
Tilidine, sold under the brand name Valoron among others, is a synthetic opioid analgesic, used mainly in Belgium, Bulgaria, Germany, Albania, Luxembourg, South Africa, and Switzerland for the treatment of moderate to severe pain, both acute and Chronic pain, chronic. Its onset of pain relief after oral administration is about 10–15 minutes and peak relief from pain occurs about 25–50 minutes after administration. Medical uses Tilidine is used in the form of hydrochloride or phosphate salt. In Germany, tilidine is available in a fixed combination with naloxone for oral administration (Valoron N and generics); the mixture of naloxone is claimed to lower the drug abuse, abuse liability of the opioid analgesic. This is so that if people take the medication orally (which is the way they are meant to) the opioid blocker, naloxone, has minimal effects on them but if they inject it the naloxone becomes bioavailable and hence antagonises the effects of the tilidine producing withd ...

Opioid
Opioids are a class of Drug, drugs that derive from, or mimic, natural substances found in the Papaver somniferum, opium poppy plant. Opioids work on opioid receptors in the brain and other organs to produce a variety of morphine-like effects, including analgesic, pain relief. The terms "opioid" and "opiate" are sometimes used interchangeably, but the term "opioid" is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain. Opiates are alkaloid compounds naturally found in the opium poppy plant ''Papaver somniferum''. Medically they are primarily used for pain relief, including anesthesia. Other medical uses include suppression of diarrhea, replacement therapy for opioid use disorder, and Cold medicine, suppressing cough. The opioid receptor antagonist naloxone is used to reverse opioid overdose. Extremely potent opioids such as carfentanil are approved only for Veterinary medicine, veterinary use. Opioids are also frequently use ...

Demethylation
Demethylation is the chemical process resulting in the removal of a methyl group (CH3) from a molecule. A common way of demethylation is the replacement of a methyl group by a hydrogen atom, resulting in a net loss of one carbon and two hydrogen atoms. The counterpart of demethylation is methylation. In biochemistry : Demethylation is relevant to epigenetics. Demethylation of DNA is catalyst, catalyzed by demethylases. These enzymes oxidize N-methyl groups, which occur in histones, in lysine derivatives, and in some forms of DNA. :R2N-CH3 + O → R2N-H + CH2O One family of such oxidative enzymes is the cytochrome P450. Alpha-ketoglutarate-dependent hydroxylases are also active for demethylation of DNA, operating by a similar stoichiometry. These reactions, which proceed via hydroxylation, exploit the slightly weakened Carbon–hydrogen bond, C-H bonds of methylamines and methyl ethers. Demethylation of some sterols are steps in the biosynthesis of testosterone and ...

Human Metabolites
Humans (''Homo sapiens'') or modern humans are the most common and widespread species of primate, and the last surviving species of the genus ''Homo''. They are great apes characterized by their hairlessness, bipedalism, and high intelligence. Humans have large brains, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups — from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's development of ...
