Reticuline is a chemical compound found in a variety of plants including Lindera aggregata , [1] Annona squamosa , [2] and Ocotea fasciculata (also known as Ocotea duckei). [3]

Contents

Reticuline is one of the alkaloids found in opium, and experiments in rodents suggest it possesses potent central nervous system depressing effects. [3] It is the precursor of morphine and many other alkaloids. It is also toxic to dopaminergic neurons causing a form of atypical parkinsonism known as Guadeloupean Parkinsonism. [4]

Metabolism

3'-hydroxy-N-methyl-(S)-coclaurine 4'-O-methyltransferase uses S-adenosyl methionine and 3'-hydroxy-N-methyl-(S)-coclaurine to produce S-adenosylhomocysteine and (S)-reticuline.

Reticuline oxidase uses (S)-reticuline and O2 to produce (S)-scoulerine and H2O2.

Salutaridine synthase uses (R)-reticuline, NADPH, H+, and O2 to produce salutaridine, NADP+, and H2O. Salutaridine can then be transformed progressively to thebaine, oripavine, and morphine.

1,2-dehydroreticulinium reductase (NADPH) uses (R)-reticuline and NADP+ to produce 1,2-dehydroreticulinium, NADPH, and H+.

<span class="mw-page-title-main">Thebaine</span> Opiate alkaloid constituent of opium

Thebaine (paramorphine), also known as codeine methyl enol ether, is an opiate alkaloid, its name coming from the Greek Θῆβαι, Thēbai (Thebes), an ancient city in Upper Egypt. A minor constituent of opium, thebaine is chemically similar to both morphine and codeine, but has stimulatory rather than depressant effects. At high doses, it causes convulsions similar to strychnine poisoning. The synthetic enantiomer (+)-thebaine does show analgesic effects apparently mediated through opioid receptors, unlike the inactive natural enantiomer (−)-thebaine. While thebaine is not used therapeutically, it is the main alkaloid extracted from Papaver bracteatum and can be converted industrially into a variety of compounds, including hydrocodone, hydromorphone, oxycodone, oxymorphone, nalbuphine, naloxone, naltrexone, buprenorphine, butorphanol and etorphine.

<i>Annona squamosa</i> Species of tree

Annona squamosa is a small, well-branched tree or shrub from the family Annonaceae that bears edible fruits called sugar apples or sweetsops. It tolerates a tropical lowland climate better than its relatives Annona reticulata and Annona cherimola helping make it the most widely cultivated of these species. Annona squamosa is a small, semi-(or late) deciduous, much-branched shrub or small tree 3 to 8 metres tall similar to soursop. It is a native of tropical climate in the Americas and West Indies, and Spanish traders aboard the Manila galleons docking in the Philippines brought it to Asia.
