Benzylisoquinoline alkaloids

Codeine is an opiate and prodrug of morphine mainly used to treat pain, coughing, and diarrhea. It is commonly used as a recreational drug. It is found naturally in the sap of the opium poppy, Papaver somniferum. It is typically used to treat mild to moderate degrees of pain. Greater benefit may occur when combined with paracetamol (acetaminophen) as codeine/paracetamol or a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Evidence does not support its use for acute cough suppression in children. In Europe, it is not recommended as a cough medicine for those under 12 y

Papaverine (Latin papaver, "poppy") is an opium alkaloid antispasmodic drug, used primarily in the treatment of visceral spasms and vasospasms (especially those involving the intestines, heart, or brain), occasionally in the treatment of erectile dysfunction and acute mesenteric ischemia. While it is found in the opium poppy, papaverine differs in both structure and pharmacological action from the analgesic morphine and its derivatives (such as codeine).

Berberine is an organic compound classified as benzylisoquinoline alkaloid. Chemically, it is a quaternary ammonia compound.

chemical compound

Dauricine is a plant metabolite, chemically classified as a phenol, an aromatic ether, and an isoquinoline alkaloid. It has been isolated from the Asian vine Menispermum dauricum, Asian moonseed, and the North American vine Menispermum canadense, Canadian moonseed. Scientists Tetsuji Kametani and Keiichiro Fukumoto of Japan are credited with being the first to synthesize dauricine in 1964, using both the Arndt-Eistert reaction and Bischler-Napieralski reaction to do so. Dauricine has been studied in vitro for its potential to inhibit cancer cell growth and to block cardiac transmembrane Na+, K

Canadine, also known as '(S)-tetrahydroberberine and xanthopuccine', is a benzylisoquinoline alkaloid (BIA), of the protoberberine structural subgroup, and is present in many plants from the family Papaveraceae, such as Corydalis yanhusuo and C. turtschaninovii.

Hydrastine is an isoquinoline alkaloid which was discovered in 1851 by Alfred P. Durand. Nitric acid induced hydrolysis of hydrastine yields hydrastinine, which was patented by Bayer as a haemostatic drug in the early 1900s. It is present in Hydrastis canadensis (thus the name) and other plants of the family Ranunculaceae.

Bicuculline is a phthalide-isoquinoline compound that is a light-sensitive competitive antagonist of GABAA receptors. It was originally identified in 1932 in plant alkaloid extracts and has been isolated from Dicentra cucullaria, Adlumia fungosa, and several Corydalis species (all in subfamily Fumarioideae, previously known as family Fumariaceae). Since it blocks the inhibitory action of GABA receptors, the action of bicuculline mimics epilepsy; it also causes convulsions. This property is utilized in laboratories around the world in the in vitro study of epilepsy, generally in hippocampal or

Phellodendrine is an alkaloid isolated originally from Phellodendron amurense (Rutaceae).

Cepharanthine is an antiinflammatory and antineoplastic compound isolated from Stephania. Due to these modalities, it has been shown effective against HTLV in lab research. Additionally, it has successfully been used to treat a diverse range of medical conditions, including radiation-induced leukopenia, idiopathic thrombocytopenic purpura, alopecia areata, alopecia pityrodes, venomous snakebites, xerostomia, sarcoidosis, refractory anemia and various cancer-related conditions. No safety issues have been observed with CEP, and side effects are very rarely reported.

(−)-Stepholidine is a protoberberine alkaloid found in the plant Stephania intermedia.

Higenamine (norcoclaurine) is a chemical compound found in a variety of plants including Nandina domestica (fruit), Aconitum carmichaelii (root), Asarum heterotropioides, Galium divaricatum (stem and vine), Annona squamosa, and Nelumbo nucifera (lotus seeds).

Narcotoline is an opiate alkaloid chemically related to noscapine. It binds to the same receptors in the brain as noscapine to act as an antitussive, and has also been used in tissue culture media.

Tetrahydropalmatine (THP) is an isoquinoline alkaloid found in several different plant species, mainly in the genus Corydalis (Yan Hu Suo), but also in other plants such as Stephania rotunda. These plants have traditional uses in Chinese herbal medicine. The pharmaceutical industry has synthetically produced the more potent enantiomer Levo-tetrahydropalmatine (Levo-THP; technically l-THP, often written L-THP), which has been marketed worldwide under different brand names as an alternative to anxiolytic and sedative drugs of the benzodiazepine group and analgesics such as opiates. It is also so

chemical compound

Corydaline is an acetylcholinesterase inhibitor isolated from Corydalis yanhusuo.

Californidine is an alkaloid with the molecular formula C20H20NO4+. It has been isolated from extracts of the California poppy (Eschscholzia californica), from which it gets its name, and from other plants of the genus Eschscholzia.

Cepharanoline is an isolate of Stephania that has antiplasmodial activity with an IC50 of 0.2 μM.

Rodiasine is a cyclic bisbenzylisoquinoline alkaloid that was first isolated from the South American greenheart tree Chlorocardium rodiei. The synthesis of O-demethylrodiasine (antioquine) and its derivatives, and the possible application of these compounds as anti-cancer, calcium channel blockers, and anti-parasitic drugs has been described.

Sinomenine or cocculine is an alkaloid found in the root of the climbing plant Sinomenium acutum which is native to Japan and China. The plant is traditionally used in herbal medicine in these countries for rheumatism and arthritis. However, analgesic action against other types of pain seems to be limited. Sinomenine is a morphinan derivative that is related to the common cough suppressant dextromethorphan. The drug's anti-rheumatic effects are thought to be primarily mediated via release of histamine, but other effects such as inhibition of prostaglandin, leukotriene and nitric oxide synthesi
