Tetrandrine a bis-benzylisoquinoline alkaloid, is a calcium channel blocker. 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 been isolated from Stephania tetrandra S Moore,[1] and other Chinese and Japanese herbs. It has vasodilatory properties and can therefore reduce blood pressure.[2] Tetrandrine may have potential use for the treatment of liver disease[3] and liver cancer.[4][5][6] Tetrandrine has potential therapeutic value to prevent excess scarring/fibrosis in conjunctiva following trabeculectomy or in patients with severe conjunctival inflammation.[7] 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.[8] 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.[9]


Tetrandrine is biosynthesized from a free radical coupled dimerization of S-N-methylcoclaurine:[10]
