Tabernaemontanine is a naturally occurring monoterpene indole alkaloid found in several species in the genus Tabernaemontana including Tabernaemontana divaricata .

Contents

History

Tabernaemontanine was first reported in 1939 [1] but its structure was only fully confirmed in the 1970s as there was confusion in the original literature regarding the configuration of the ethyl group in the piperidine ring of this alkaloid and its isomer dregamine, so that their identities had been reversed. [2] [3] [4] Both compounds were isolated from plants of the dogbane (Apocynaceae) family including Tabernaemontana coronaria . [5] They have structures that are reduced versions of vobasine.

Biosynthesis

As with other Indole alkaloids, the biosynthesis of tabernaemontanine starts from the amino acid tryptophan. This is converted into strictosidine before further elaboration. [6]

Natural occurrence

Tabernaemontana divaricata, a source of tabernaemontanin

Tabernaemontanine is found commonly in the genera Tabernaemontana and Kopsia , [7] including the species Ervatamia hirta , [8] Tabernaemontana elegans [9] and Tabernaemontana divaricata . [10] [11] The latter species is known to produce many other alkaloids including catharanthine, ibogamine and voacristine. [12]

Research

Plant metabolites have been of interest for their possible biological activity and alkaloids in particular are major subjects for ethnobotanical research. [13] [14] Tabernaemontanine has been studied, for example as a potential anti-cancer agent, [15] [16] [17] [18] for its antimalarial activity [19] [20] and in antifertility research. [21] However, the alkaloid itself has not been developed as a drug.

Voacangine is an alkaloid found predominantly in the root bark of the Voacanga africana tree, as well as in other plants such as Tabernanthe iboga, Tabernaemontana africana, Trachelospermum jasminoides, Tabernaemontana divaricata and Ervatamia yunnanensis. It is an iboga alkaloid which commonly serves as a precursor for the semi-synthesis of ibogaine. It has been demonstrated in animals to have similar anti-addictive properties to ibogaine itself. It also potentiates the effects of barbiturates. Under UV-A and UV-B light its crystals fluoresce blue-green, and it is soluble in ethanol.

<span class="mw-page-title-main">Indole alkaloid</span> Class of alkaloids

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. Many of them possess significant physiological activity and some of them are used in medicine. The amino acid tryptophan is the biochemical precursor of indole alkaloids.

It is thought to be intermediate compound in many different biosynthetic pathways such as in Aspidosperma species. Many alkaloids are proposed to be produced through intermediate stemmadenine. Some of them are:
