Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral [2] and even weakly acidic properties. [3] Some synthetic compounds of similar structure may also be termed alkaloids. [4]
Isoquinoline is an individual chemical specimen - a heterocyclic aromatic organic compound - as well as the name of a family of many thousands of natural plant alkaloids, any one of which might be referred to as "an isoquinoline". It is a structural isomer of quinoline.
Structural formula of indole. Indole alkaloids are a class of alkaloids containing a structural moiety of indole; many indole alkaloids also include isoprene groups and are thus called terpene indole or secologanin tryptamine alkaloids. Containing more than 4100 known different compounds, it is one of the largest classes of alkaloids. [1]
In general, isoquinoline alkaloids can have different effects. The opium alkaloids may have sedative, psychotropic or analgesic properties. [7] Morphine and codeine are indeed used as analgesics. [8] Papaverine, in contrast, has an antispasmodic effect if it comes from smooth muscles, as is the case in humans in the gastrointestinal tract or ...
Opium poppy contains at least 50 different alkaloids, but most of them are of very low concentration. Morphine is the principal alkaloid in raw opium and constitutes roughly 8–19% of opium by dry weight (depending on growing conditions). [84] Some purpose-developed strains of poppy now produce opium that is up to 26% morphine by weight.
Buxus steroid alkaloids are present in the leaves of the common boxwood (Buxus sempervirens). This plant primarily thrives in southern and central Europe. These alkaloids are characterized by an amino group attached to the 3rd and/or 20th carbon atom. Methylation of the amino groups can be partial, complete, or absent.
An alkaloid is a naturally occurring nitrogenous organic molecule that has a pharmacological effect on humans and other animals. The name derives from the word alkaline; originally, the term was used to describe any nitrogen-containing base (an amine in modern terms). Alkaloids are found in plants (e.g., in potatoes and tomatoes), animals (e.g ...
Morphine. Synthesis of morphine-like alkaloids in chemistry describes the total synthesis of the natural morphinan class of alkaloids that includes codeine, morphine, oripavine, and thebaine and the closely related semisynthetic analogs methorphan, buprenorphine, hydromorphone, hydrocodone, isocodeine, naltrexone, nalbuphine, oxymorphone, oxycodone, and naloxone.
