Pethidinic acid (meperidinic acid, pethidine intermediate C) is a 4-phenyl piperidine derivative that is both a metabolite of and a precursor to pethidine (meperidine). [2] [3] It is scheduled by UN Single Convention on Narcotic Drugs. It is a Schedule II Narcotic controlled substance in the United States and has an ACSCN of 9234. The 2014 annual manufacturing quota was 6 grams. [4]
Pethidinic acid is a controlled drug because of its potential uses in manufacturing both pethidine itself and some of its substituted derivatives, but it has little opioid activity in its own right. Metabolism of pethidine to pethidinic acid is carried out mainly by the carboxylesterase enzyme hCE-1 in the liver, [5] and since the activity of this enzyme can vary between individuals, the rate and extent of pethidinic acid production can vary. [6] [7]
Frank Wätjen used pethidinic acid as a precursor chemical to a heterocyclic moiety. [8]
Safrole is an organic compound with the formula CH2O2C6H3CH2CH=CH2. It is a colorless oily liquid, although impure samples can appear yellow. A member of the phenylpropanoid family of natural products, it is found in sassafras plants, among others. Small amounts are found in a wide variety of plants, where it functions as a natural antifeedant. Ocotea pretiosa, which grows in Brazil, and Sassafras albidum, which grows in eastern North America, are the main natural sources of safrole. It has a characteristic "sweet-shop" aroma.
Desmethylprodine or 1-methyl-4-phenyl-4-propionoxypiperidine is an opioid analgesic drug developed in the 1940s by researchers at Hoffmann-La Roche. Desmethylprodine has been labeled by the DEA as a Schedule I drug in the United States. It is an analog of pethidine (meperidine) a Schedule II drug. Chemically, it is a reversed ester of pethidine which has about 70% of the potency of morphine. Unlike its derivative prodine, it was not reported to exhibit optical isomerism. It was reported to have 30 times the activity of pethidine and a greater analgesic effect than morphine in rats, and it was demonstrated to cause central nervous system stimulation in mice.
Pethidine, also known as meperidine and sold under the brand name Demerol among others, is a synthetic opioid pain medication of the phenylpiperidine class. Synthesized in 1938 as a potential anticholinergic agent by the German chemist Otto Eisleb, its analgesic properties were first recognized by Otto Schaumann while working for IG Farben, Germany. Pethidine is the prototype of a large family of analgesics including the pethidine 4-phenylpiperidines, the prodines, bemidones and others more distant, including diphenoxylate and analogues.
Phenylacetone, also known as phenyl-2-propanone, is an organic compound with the chemical formula C6H5CH2COCH3. It is a colorless oil that is soluble in organic solvents. It is a mono-substituted benzene derivative, consisting of an acetone attached to a phenyl group. As such, its systematic IUPAC name is 1-phenyl-2-propanone.
Anileridine is a synthetic analgesic drug and is a member of the piperidine class of analgesic agents developed by Merck & Co. in the 1950s. It differs from pethidine (meperidine) in that the N-methyl group of meperidine is replaced by an N-aminophenethyl group, which increases its analgesic activity.
Phenoperidine(Operidine or Lealgin), is an opioid analgesic which is structurally related to pethidine and is used clinically as a general anesthetic.
Haloxazolam, is a drug which is a benzodiazepine derivative. It has similar hypnotic properties as the benzodiazepine drugs triazolam, temazepam, and flunitrazepam and as such is indicated for the treatment of insomnia. A study in cats comparing estazolam and haloxazolam found that haloxazolam only affects gamma motor neurons, whereas estazolam affects both alpha and gamma motor neurons.
Hydroxypethidine (Bemidone) is an opioid analgesic that is an analogue of the more commonly used pethidine (meperidine). Hydroxypethidine is slightly more potent than meperidine as an analgesic, 1.5x meperidine in potency, and it also has NMDA antagonist properties like its close relative ketobemidone.
Mesocarb is a drug that is currently being developed for Parkinson's disease.
Prodine is an opioid analgesic that is an analog of pethidine (meperidine). It was developed in Germany in the late 1940s.
Norpethidine is a 4-phenylpiperidine derivative that is both a precursor to, and the toxic metabolite of, pethidine (meperidine). It is scheduled by UN Single Convention on Narcotic Drugs. It is a Schedule II Narcotic controlled substance in the United States and has an ACSCN of 9233. The 2014 annual manufacturing quota was 11 grams (0.39 oz).
Benzethidine is a 4-phenylpiperidine derivative that is related to the clinically used opioid analgesic drug pethidine.
Etoxeridine is a 4-phenylpiperidine derivative that is related to the clinically used opioid analgesic drug pethidine (meperidine).
Furethidine is a 4-phenylpiperidine derivative that is related to the clinically used opioid analgesic drug pethidine (meperidine), but with around 25x higher potency. According to another source, Furethidine is 500/30 = 16.7 x the potency of pethidine.
Morpheridine (Morpholinoethylnorpethidine) is a 4-phenylpiperidine derivative that is related to the clinically used opioid analgesic drug pethidine (meperidine). It is a strong analgesic with around 4 times the potency of pethidine, and unlike pethidine, does not cause convulsions, although it produces the standard opioid side effects such as sedation and respiratory depression.
Oxpheneridine is a 4-phenylpiperidine derivative that is related to the opioid analgesic drug pethidine (meperidine).
Pethidine intermediate A is a 4-phenylpiperidine derivative that is a precursor to the opioid analgesic drug pethidine (meperidine). It is not known to have any analgesic activity in its own right, however other derivatives of pethidine with a 4-cyano group in place of the carboxylate ethyl ester have been found to be active, so pethidine intermediate A might also show opioid effects. It is scheduled by UN Single Convention on Narcotic Drugs. It is a Schedule II Narcotic controlled substance in the United States and has an ACSCN of 9232. The 2014 annual manufacturing quota was 6 grammes.
Normorphine is an opiate analogue, the N-demethylated derivative of morphine, that was first described in the 1950s when a large group of N-substituted morphine analogues were characterized for activity. The compound has relatively little opioid activity in its own right, but is a useful intermediate which can be used to produce both opioid antagonists such as nalorphine, and also potent opioid agonists such as N-phenethylnormorphine. with its formation from morphine catalyzed by the liver enzymes CYP3A4 and CYP2C8.
Moramide intermediate is a moramide precursor scheduled by UN Single Convention on Narcotic Drugs.
Methadone intermediate is a methadone precursor scheduled by UN Single Convention on Narcotic Drugs. It is a Schedule II Narcotic controlled substance in the United States and has an ACSCN of 9254. The 2014 annual manufacturing quota was 32 875 kilos.
