Alimadol (INN; A-4020) is an opioid analgesic related to methadone which was never marketed. [1]
Methadone, sold under the brand names Dolophine and Methadose among others, is a synthetic opioid used medically to treat chronic pain and opioid use disorder. Prescribed for daily use, the medicine relieves cravings and opioid withdrawal symptoms. Withdrawal management using methadone can be accomplished in less than a month, or it may be done gradually over a longer period of time, or simply maintained for the rest of the patient's life. While a single dose has a rapid effect, maximum effect can take up to five days of use. After long-term use, in people with normal liver function, effects last 8 to 36 hours. Methadone is usually taken by mouth and rarely by injection into a muscle or vein.
BINAP (2,2′-bis(diphenylphosphino)-1,1′-binaphthyl) is an organophosphorus compound. This chiral diphosphine ligand is widely used in asymmetric synthesis. It consists of a pair of 2-diphenylphosphinonaphthyl groups linked at the 1 and 1′ positions. This C2-symmetric framework lacks a stereogenic atom, but has axial chirality due to restricted rotation (atropisomerism). The barrier to racemization is high due to steric hindrance, which limits rotation about the bond linking the naphthyl rings. The dihedral angle between the naphthyl groups is approximately 90°. The natural bite angle is 93°.
Biphenyl is an organic compound that forms colorless crystals. Particularly in older literature, compounds containing the functional group consisting of biphenyl less one hydrogen may use the prefixes xenyl or diphenylyl.
The Controlled Drugs and Substances Act is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the Narcotic Control Act and Parts III and IV of the Food and Drugs Act, and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest."
Lefetamine (Santenol) is a drug which is a stimulant and also an analgesic with effects comparable to codeine.
The Wagner-Jauregg reaction is a classic organic reaction in organic chemistry, named after Theodor Wagner-Jauregg, describing the double Diels–Alder reaction of 2 equivalents of maleic anhydride with a 1,1-diarylethylene. After aromatization of the bis-adduct, the ultimate reaction product is a naphthalene compound with one phenyl substituent.
Phenadoxone is an opioid analgesic of the open chain class invented in Germany by Hoechst in 1947. It is one of a handful of useful synthetic analgesics which were used in the United States for various lengths of time in the 20 or so years after the end of the Second World War but which were withdrawn from the market for various or no known reason and which now are mostly in Schedule I of the United States' Controlled Substances Act of 1970, or in Schedule II but not produced or marketed in the US. Others on this list are ketobemidone (Ketogin), dextromoramide, phenazocine, dipipanone, piminodine (Alvodine), propiram (Algeril), anileridine (Leritine) and alphaprodine (Nisentil).
Levacetylmethadol (INN), levomethadyl acetate (USAN), OrLAAM or levo-α-acetylmethadol (LAAM) is a synthetic opioid similar in structure to methadone. It has a long duration of action due to its active metabolites.
Etifelmine is a stimulant drug. It was used for the treatment of hypotension.
Hexobendine is a vasodilator that acts as an adenosine reuptake inhibitor.
IC-26 is an analogue of the opioid analgesic methadone, where the carbonyl group has been replaced by the bioisosteric sulfone group.
Fezolamine (Win-41,528-2) is a drug which was investigated by Sterling Drug as an antidepressant in the 1980s. The isomeric N,N-dimethyl-4,5-diphenyl-1H-pyrazole-1-propanamine was completely inactive in the primary antidepressant screens.
In organic chemistry, the thiol-yne reaction is an organic reaction between a thiol and an alkyne. The reaction product is an alkenyl sulfide.
Cyclarbamate, also known as cyclopentaphene, is a muscle relaxant and tranquilizer of the carbamate family which has been marketed by Cassenne in France since 1961.
Methade, or 6-(dimethylamino)-4,4-diphenylheptane, is the parent compound of the methadone and methadol series of opioid analgesics:
Max Bockmühl was a German inventor and chemist.
Moramide intermediate is a moramide precursor scheduled by UN Single Convention on Narcotic Drugs.
Gustav Ehrhart was a German chemist. He synthesized the first fully synthetic opioid analgesic, methadone, together with Max Bockmühl.
The hexafluoroarsenate anion is a chemical species with formula AsF−6. Hexafluoroarsenate is relatively inert, being the conjugate base of the notional superacid hexafluoroarsenic acid.
Ilona Graenitz was an Austrian politician who served in the National Council of Austria and the European Parliament as a member of the Social Democratic Party of Austria.
