Thebaïne
Thebaine (paramorphine), also known as codeine methyl enol ether, is an opiate alkaloid, its name coming from the Greek Θῆβαι, '' Thēbai'' (Thebes), an ancient city in Upper Egypt. A minor constituent of opium, thebaine is chemically similar to both morphine and codeine, but has stimulatory rather than depressant effects. At high doses, it causes convulsions similar to strychnine poisoning. The synthetic enantiomer (+)-thebaine does show analgesic effects apparently mediated through opioid receptors, unlike the inactive natural enantiomer (−)-thebaine. While thebaine is not used therapeutically, it is the main alkaloid extracted from ''Papaver bracteatum'' (Iranian opium / Persian poppy) and can be converted industrially into a variety of compounds, including hydrocodone, hydromorphone, oxycodone, oxymorphone, nalbuphine, naloxone, naltrexone, buprenorphine, butorphanol and etorphine. Thebaine is controlled under international law, is listed as a Class A drug under the Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Opiate
An opiate is an alkaloid substance derived from opium (or poppy straw). It differs from the similar term ''opioid'' in that the latter is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain (including antagonists). Opiates are alkaloid compounds naturally found in the opium poppy plant ''Papaver somniferum''. The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. Opiates have long been used for a variety of medical conditions, with evidence of opiate trade and use for pain relief as early as the eighth century AD. Most opiates are considered drugs with moderate to high abuse potential and are listed on various "Substance-Control Schedules" under the Uniform Controlled Substances Act of the United States of America. In 2014, between 13 and 20 million people used opioids recreationally, representing 0.3% to 0.4% of the global population between the ages of 15 and 65. According to the CDC, ...

Naltrexone
Naltrexone, sold under the brand name Revia among others, is a medication primarily used to manage alcohol use or opioid use disorder by reducing cravings and feelings of euphoria associated with substance use disorder. It has also been found effective in the treatment of other addictions and may be used for them off-label. An opioid-dependent person should not receive naltrexone before detoxification. It is taken orally or by injection into a muscle. Effects begin within 30 minutes, though a decreased desire for opioids may take a few weeks to occur. Side effects may include trouble sleeping, anxiety, nausea, and headaches. In those still on opioids, opioid withdrawal may occur. Use is not recommended in people with liver failure. It is unclear if use is safe during pregnancy. Naltrexone is an opioid antagonist and works by blocking the effects of opioids, including both opioid drugs as well as opioids naturally produced in the brain. Naltrexone was first m ...

Poppy Seeds
Poppy seed is an oilseed obtained from the poppy plant (''Papaver somniferum''). The tiny, kidney-shaped seeds have been harvested from dried seed pods by various civilizations for thousands of years. It is still widely used in many countries, especially in Central Europe and South Asia, where it is legally grown, used in food products and sold in shops. The seeds are used whole or ground into meal as an ingredient in many foods – especially in pastry and bread – and they are pressed to yield poppyseed oil. History The poppy seed is mentioned in ancient medical texts from many civilizations. For instance, the Egyptian Ebers Papyrus, written c. 1550 BCE, lists the poppy seed as a sedative. The Minoan civilization (approximately 2700 to 1450 BCE), a Bronze Age civilization which arose on the island of Crete, cultivated poppies for their seeds, and used a milk, opium and honey mixture to calm crying babies. The Sumerians are another civilization that are known to have grown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Canberra Times
''The Canberra Times'' is a daily newspaper in Canberra, Australia, which is published by Australian Community Media. It was founded in 1926, and has changed ownership and format several times. History ''The Canberra Times'' was launched in 1926 by Thomas Shakespeare along with his oldest son Arthur Shakespeare and two younger sons Christopher and James. The newspaper's headquarters were originally located in the Civic retail precinct, in Cooyong Street and Mort Street, in blocks bought by Thomas Shakespeare in the first sale of Canberra leases in 1924. The newspaper's first issue was published on 3 September 1926. It was the second paper to be printed in the city, the first being '' The Federal Capital Pioneer''. Between September 1926 and February 1928, the newspaper was a weekly issue. The first daily issue was 28 February 1928. In June 1956, ''The Canberra Times'' converted from broadsheet to tabloid format. Arthur Shakespeare sold the paper to John Fairfax ...

Poppy Straw
Poppy straw (also known as opium straw, mowed opium straw, crushed poppy capsule, poppy chaff, or poppy husk) is derived from opium poppies (''Papaver somniferum'') that are harvested when fully mature and dried by mechanical means. Opium poppy straw is what remains after the seed pods have been that is, the dried stalks, stem and leaves of poppies grown for their seeds. The field-dried leaves, stalk, and seed pod are then used in commercial manufacture of morphine or other poppy-alkaloid derived drugs, by first processing the material, separating the seeds, and then making concentrate of poppy straw where no extraction using the traditional methods of latex extraction has been made. The straw was originally considered an agricultural by-product of the mechanised poppy seed harvest, which was primarily grown for its edible and oil-producing seed. This changed in 1927 when János Kabay developed a chemical process to extract morphine from the crushed capsule. Concentrated poppy stra ...

Reticuline
Reticuline is an alkaloid found in opium and a variety of plants including ''Lindera aggregata'', ''Annona squamosa'', and ''Ocotea#Selected species, Ocotea fasciculata'' (also known as ''Ocotea duckei''). Experiments in rodents suggest reticuline possesses potent central nervous system depressant, depressing effects. It is the precursor of morphine and many other alkaloids. It is also toxic to dopaminergic neurons causing a form of Parkinson plus syndrome, atypical parkinsonism known as Guadeloupean Parkinsonism. Metabolism 3'-hydroxy-N-methyl-(S)-coclaurine 4'-O-methyltransferase uses S-Adenosyl methionine, ''S''-adenosyl methionine and 3'-hydroxy-''N''-methyl-(''S'')-coclaurine to produce S-Adenosyl-L-homocysteine, ''S''-adenosylhomocysteine and (''S'')-reticuline. Reticuline oxidase uses (''S'')-reticuline and O2 to produce (''S'')-scoulerine and H2O2. Salutaridine synthase uses (''R'')-reticuline, NADPH, H+, and O2 to produce salutaridine, NADP+, and H2O.

Oripavine
Oripavine is an opioid and the major metabolite of thebaine. It is the precursor to the semi-synthetic compounds etorphine and buprenorphine. Although this chemical compound has analgesic potency comparable to morphine, it is not used clinically due to severe adverse effects and a low therapeutic index. Being a precursor to a series of extremely strong opioids, oripavine is a controlled substance in some jurisdictions. Pharmacological properties Oripavine possesses an analgesic potency comparable to morphine; however, it is not clinically useful due to severe toxicity and low therapeutic index. In both mice and rats, toxic doses caused tonic-clonic seizures followed by death, similar to thebaine. Oripavine has a potential for dependence which is significantly greater than that of thebaine but slightly less than that of morphine. Bridged derivatives (The Bentley compounds) Of much greater relevance are the properties of the orvinols, a large family of semi-synthet ...

Salutaridine
Salutaridine, also known as floripavine, is an alkaloid Alkaloids are a broad class of natural product, naturally occurring organic compounds that contain at least one nitrogen atom. Some synthetic compounds of similar structure may also be termed alkaloids. Alkaloids are produced by a large varie ... that is present in the morphinian alkaloid pathway of opium poppy. Its biosynthetic precursor is the alkaloid (''R'')-reticuline. (''R'')-Reticuline is converted to salutaridine by the enzyme salutaridine synthase. Salutaridine is converted to salutaridinol by the enzyme salutaridine reductase (SalR), with the reduction of NADPH to NADP+.

Analog Act
The Federal Analogue Act, , is a section of the United States Controlled Substances Act passed in 1986 which allows any chemical "substantially similar" to a controlled substance listed in Schedule I or II to be treated as if it were listed in Schedule I, but only if intended for human consumption. These similar substances are often called designer drugs. The law's broad reach has been used to successfully prosecute possession of chemicals openly sold as dietary supplements and naturally contained in foods (e.g., the possession of phenethylamine, a compound found in chocolate, has been successfully prosecuted based on its "substantial similarity" to the controlled substance methamphetamine). The law's constitutionality has been questioned by now Supreme Court Justice Neil Gorsuch on the basis of Vagueness doctrine. Definition (32) *(A) Except as provided in subparagraph (C), the term ''controlled substance analogue'' means a substance - **(i) the chemical structure of which i ...
