The first individual alkaloid, morphine, was isolated in 1804 from the opium poppy (Papaver somniferum). [1] 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]
Protopine is an alkaloid occurring in opium poppy, [2] Corydalis tubers [3] and other plants of the family papaveraceae, like Fumaria officinalis. [4] Protopine is metabolically derived from the benzylisoquinoline alkaloid (S)-Reticuline through a progressive series of five enzymatic transformations: 1) berberine bridge enzyme to -Scoulerine; 2) (S)-cheilanthifoline synthase/CYP719A25 to (S ...
The most common flavonoid alkaloids contain a nitrogen heterocycle such as a pyridine or piperidine which is covalently bonded to the A-ring of a chromone. One flavonoid alkaloid, lilaline, was isolated from Lilium candidum in 1987. [2] The synthesis of flavonoid alkaloids has been achieved [3]
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).
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]
The free base form of cocaine is prepared from cocaine hydrochloride by extracting the cocaine with an alkaline solution (sodium hydroxide or ammonia) and adding a non-polar solvent such as diethyl ether or benzene. The mixture separates into two layers, the top solvent layer containing the dissolved cocaine.
Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms. Molecules containing polar bonds have no molecular polarity if the bond dipoles cancel each other out by symmetry. Polar molecules interact through dipole-dipole intermolecular forces and hydrogen bonds.
Latifolinin is a compound that is naturally present in the bark of Funtumia latifolia. Additionally, the leaves of this plant contain two other compounds, namely funtumin and funtumidin. These compounds belong to the Apocynaceae steroid alkaloids family and share the 5α-pregnan backbone structure. [4]
