How are opoiods derived from the opium poppy?
Best insight from top research papers
Opium alkaloids, including opioids such as morphine, codeine, thebaine, noscapine, and papaverine, are derived from the opium poppy (Papaver somniferum L.) . These alkaloids are secondary metabolites produced in the latex of the poppy capsule . The biosynthesis of alkaloids involves multistep reactions, mainly derived from amino acids . Opium poppy genome-wide transcriptome analyses have revealed the differential expression of genes related to alkaloid biosynthesis, including NCS, CNMT, SalR, 16TOMT, 6OMT, COR, and StySyn . The opium poppy genome also shows evidence of gene duplication, rearrangement, and fusion events that have led to the evolution of specialized metabolic products, such as morphinan-based painkillers . The opium alkaloids, particularly morphine and codeine, have been detected in poppy seeds, which are widely used in the food industry . However, thermal processing of poppy seeds reduces the levels of alkaloids, making them unlikely to exceed recommended safe levels .

What is the mechanism of the poppy alkaloids against insects?5 answersPoppy alkaloids, such as morphinan alkaloids found in Papaver somniferum, act as a defense mechanism against herbivory. These alkaloids accumulate in the plant's capsules, with shade during early floral development significantly reducing capsule size, alkaloid yield, and seed number. The alkaloids in poppies have toxic properties and are involved in insecticidal activities. Additionally, the geometry study of alkaloids in Argemone Mexicana Linn seeds revealed their toxic, bactericidal, hallucinogenic, and insecticidal properties. The phototoxicity of naturally occurring alkaloids was also observed against Escherichia coli and Trichoplusia ni, suggesting hydrophobic mechanisms play a role in their insecticidal effects. Overall, poppy alkaloids serve as chemical defensive weapons against insects through their toxic properties and impact on insect behavior.
What are the medicinal used of Opium poppy?4 answersOpium poppy (Papaver somniferum) has been used for medicinal purposes for centuries. It is known for its analgesic and hypnotic properties, making it useful as a pain reliever and sleep aid. The plant contains benzylisoquinoline alkaloids (BIAs), including morphine and codeine, which are widely used as narcotic analgesics. Opium poppy is also rich in oil content in its seeds, making it a valuable source of food. Additionally, opium poppy has been used in traditional medicine for various purposes, including as an analgesic, sedative, stimulant, and nutritive agent. The plant is also known for its antispasmodic, antitussive, and sedative properties. Overall, opium poppy has a long history of medicinal use and continues to be an important source of therapeutic compounds.
What are the different methods for synthesizing dexanabinol?5 answersDifferent methods for synthesizing dexanabinol are described in the provided abstracts. One method involves the ester exchange of 2,4-dyhydroxy-6-pentyl methyl benzoate with N,N-dialkyl alcohol amine under potassium hydroxide catalysis, followed by a coupled reaction with (1S, 4R)-1-methyl-4-(1-methylvinyl)-2-cyclohexene-1-alcohol under Lewis acid catalysis. Another method involves reacting a malononitrile derivative with a dehydrating agent, and then reacting the reaction product with a nucleophilic agent to synthesize a dicyanomethylidene compound, which can be further reacted with a hydrazine compound to synthesize a heterocyclic compound. The abstracts do not provide information on specific methods for synthesizing dexanabinol.
What are some of the drugs that are derived from plants?4 answersPlants have been a valuable source of drugs, including anticancer and antibacterial agents. Some of the anticancer drugs derived from plants include podophyllotoxin (teniposide and etoposide), taxanes (docetaxel and paclitaxel), and vinca alkaloids (vinorelbine, vincristine, vindesine, and vinblastine). In the field of antibacterial drugs, plants offer a wide variety of secondary metabolites with potential antimicrobial activity. However, only a small percentage of these compounds have been examined under clinical trials, and currently, plants contribute only 3% to the repertoire of FDA-approved antibacterial drugs. Additionally, plant-derived compounds have shown promise as immunomodulators, with examples such as Tinospora cordifolia, Andrographis paniculata, Curcuma longa, Zingiber officinale, Allium sativum, Terminalia chebula, and Piper longum displaying significant immunomodulatory potential.
What is opium trade by alfred mccoy?3 answersThe opium trade, particularly originating in Afghanistan, has significant global impacts on health, governance, security, stability, and development. It poses threats to the security and stability of Afghanistan due to factors such as predatory warlords, the Taliban-led insurgency, and general criminality. The trade of Afghan opiates and precursor chemicals used to produce heroin has worldwide flows, affecting regions beyond Afghanistan and its neighbors. The history of the opium trade, including the nineteenth century trade, provides insights into the current Asian heroin traffic. Scholars studying U.S. intervention in Southeast Asia also recognize the importance of understanding the submerged operations of crime in the region. The response to the threats posed by the opium trade and the security situation in Afghanistan has been insufficient, with challenges such as lack of resources, corruption, and inadequate direction.
What is the origin of papaya?5 answersPapaya is believed to have originated in Southern Mexico and neighboring Central America. It is native to the tropics of the Americas, particularly from southern Mexico and Central America. The exact center of origin is difficult to define, but there is evidence suggesting a Mesoamerican origin, specifically the south of Mexico and Central America. It is a fruit crop that is native to tropical America. The fruit is commonly found in tropical and sub-tropical regions, and it is cultivated in various countries including Australia, Hawaii, Brazil, Malaysia, Burma, Philippines, Sri Lanka, India, South Africa, Thailand, and Tropical America.
