(S)-Canadine, also known as (S)-tetrahydroberberine and xanthopuccine, is a benzylisoquinoline alkaloid (BIA), of the protoberberine structural subgroup, and is present in many plants from the family Papaveraceae, such as Corydalis yanhusuo and C. turtschaninovii.

Biosynthesis

[edit]

Metabolically, (S)-canadine is derived from (S)-reticuline, a pivotal intermediate in the biosynthesis of numerous BIA structural subgroups, through three enzymatic steps: 1) Berberine bridge enzyme to (S)-scoulerine; 2) (S)-scoulerine 9-O-methyltransferase to (S)-tetrahydrocolumbamine; and 3) (S)-canadine synthase/CYP719A21 to (S)-canadine.[1]

(S)-Canadine is the immediate metabolic precursor of berberine, which is obtained through the action of the enzyme (S)-tetrahydroprotoberberine oxidase.[1] It is also an intermediate in the complex biosynthesis of noscapine, which is likewise a benzylisoquinoline alkaloid, but of the phthalideisoquinoline structural subgroup.[2][3]

(S)-Canadine, berberine, palmatine, and hydrastine are the major alkaloids present in goldenseal.

Effects

[edit]

A number of in vitro effects of (S)-canadine have been reported. It stimulates myogenesis and inhibits muscle protein degradation.[4] (S)-Canadine blocks K(ATP) channels in dopamine neurons.[5][6] (S)-Canadine has displayed antioxidant activity: though it lacked any demonstrable cytotoxic effect in three unique cell cultures, it was observed to possess antioxidant activity against free radical-induced oxidative injury.[7][8] (S)-Canadine can block voltage-dependent calcium channels, but at a level significantly lower than that of verapamil.[9]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
