Tetrandrine, a bis-benzylisoquinoline alkaloid, is a calcium channel blocker.[1] It is isolated from the plant Stephania tetrandra,[2] and other Chinese and Japanese herbs.

Pharmacology

[edit]

It has anti-inflammatory, immunologic and antiallergenic effects. It inhibits the degranulation of mast cells. It has a quinidine-like anti-arrhythmic effect. It has vasodilatory properties and can therefore reduce blood pressure.[3] Tetrandrine may have potential use for the treatment of liver disease[4] and liver cancer.[5][6][7] Tetrandrine has potential therapeutic value to prevent excess scarring/fibrosis in conjunctiva following trabeculectomy or in patients with severe conjunctival inflammation.[8] Tetrandrine has anti-inflammatory and anti-fibrogenic actions, which make tetrandrine and related compounds potentially useful in the treatment of lung silicosis, liver cirrhosis, and rheumatoid arthritis.[9] Tetrandrine has also been shown to inhibit entry of Ebola virus into host cells in vitro and showed therapeutic efficacy against Ebola in preliminary studies on mice.[10][1] Tetrandrine has also been studied and patented as a possible treatment for tinnitus.[11][12][13]

Biosynthesis

[edit]

Tetrandrine is biosynthesized from a free radical coupled dimerization of S-N-methylcoclaurine:[14]

Synonyms

[edit]

Synonyms include fanchinine, hanfangchin A, NSC 77037, (S,S)-(+)-tetrandrine, sinomenine A, TTD, tetrandrin, d-tetrandrine, and GW-201.[15][13]
