Desacetoxyvindoline is a terpene indole alkaloid produced by the plant Catharanthus roseus . Desacetoxyvindoline is a product formed by the methylation of the nitrogen on the indole ring by the enzyme 3-hydroxy-16-methoxy-2,3-dihydrotabersonine N-methyltransferase (NMT). [1] The metabolite is a substrate for desacetoxyvindoline 4-hydroxylase (D4H) which catalyzes a hydroxylation to yield deacetylvindoline. [2]

<i>Catharanthus roseus</i> Species of flowering plant in the family Apocynaceae

Catharanthus roseus, commonly known as bright eyes, Cape periwinkle, graveyard plant, Madagascar periwinkle, old maid, pink periwinkle, rose periwinkle, is a perennial species of flowering plant in the family Apocynaceae. It is native and endemic to Madagascar, but grown elsewhere as an ornamental and medicinal plant. It is a source of the drugs vincristine and vinblastine, used to treat cancer. It was formerly included in the genus Vinca as Vinca rosea.

<i>Vinca</i> alkaloid

Vinca alkaloids are a set of anti-mitotic and anti-microtubule alkaloid agents originally derived from the periwinkle plant Catharanthus roseus and other vinca plants. They block beta-tubulin polymerization in a dividing cell.

<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.

<span class="mw-page-title-main">Strictosidine</span> Chemical compound

Strictosidine is a natural chemical compound and is classified as a glucoalkaloid and a vinca alkaloid. It is formed by the Pictet–Spengler condensation reaction of tryptamine with secologanin, catalyzed by the enzyme strictosidine synthase. Thousands of strictosidine derivatives are sometimes referred to by the broad phrase of monoterpene indole alkaloids. Strictosidine is an intermediate in the biosynthesis of numerous pharmaceutically valuable metabolites including quinine, camptothecin, ajmalicine, serpentine, vinblastine, vincristine and mitragynine.

<span class="mw-page-title-main">Tabersonine</span> Chemical compound

Tabersonine is a terpene indole alkaloid found in the medicinal plant Catharanthus roseus and also in the genus Voacanga. Tabersonine is hydroxylated at the 16 position by the enzyme tabersonine 16-hydroxylase (T16H) to form 16-hydroxytabersonine. The enzyme leading to its formation is currently unknown. Tabersonine is the first intermediate leading to the formation of vindoline one of the two precursors required for vinblastine biosynthesis.

<span class="mw-page-title-main">16-Hydroxytabersonine</span> Chemical compound

16-Hydroxytabersonine is a terpene indole alkaloid produced by the plant Catharanthus roseus. The metabolite is an intermediate in the formation of vindoline, a precursor needed for formation of the pharmaceutically valuable vinblastine and vincristine. 16-hydroxytabersonine is formed from the hydroxylation of tabersonine by tabersonine 16-hydroxylase (T16H). Tabersonine 16-O-methyltransferase (16OMT) methylates the hydroxylated 16 position to form 16-methoxytabersonine.

<span class="mw-page-title-main">3-Hydroxy-16-methoxy-2,3-dihydrotabersonine</span> Chemical compound

3-Hydroxy-16-methoxy-2,3-dihydrotabersonine is a terpene indole alkaloid produced by Catharanthus roseus. The metabolite is a substrate for 3-hydroxy-16-methoxy-2,3-dihydrotabersonine N-methyltransferase (NMT) which transfers a methyl group to the nitrogen of the indole ring forming desacetoxyvindoline. The enzyme catalyzing the formation of 3-hydroxy-16-methoxy-2,3-dihydrotabersonine from 16-methoxytabersonine is currently unknown, but is a result of hydration of the double bond connecting the 6 and 13 position carbons.

<span class="mw-page-title-main">16-Methoxytabersonine</span> Chemical compound

16-Methoxytabersonine is a terpene indole alkaloid produced by the medicinal plant Catharanthus roseus. 16-methoxytabersonine is synthesized by methylation of the hydroxyl group at the 16 position of 16-hydroxytabersonine by tabersonine 16-O-methyltransferase (16OMT). The compound is a substrate for hydration by two concerted enzymes Tabersonine-3-Oxidase (T3O) and Tabersonine-3-Reductase (T3R), which leads to the formation of 3-hydroxy-16-methoxy-2,3-dihydrotabersonine.
