MedKoo CAT#: 202900

CAS#: 518-34-3

Description: Tetrandrine is a bisbenylisoquinoline alkaloid isolated from the dried root of Stephenia tetrandra S Moore. Tetrandrine exhibits very broad pharmacological actions, including anti-tumor activity. The beneficial effects of tetrandrine on tumor cell cytotoxicity and radiosensitization, multidrug resistance, normal tissue radioprotection, and angiogenesis are most promising and deserve great attention. Tetrandrine has potential either as a tumoricidal agent or as an adjunct to chemotherapy and radiotherapy.

Additional Information

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,  and other Chinese and Japanese herbs. It has vasodilatory properties and can therefore reduce blood pressure. Tetrandrine may have potential use for the treatment of liver disease and liver cancer.  Tetrandrine has potential therapeutic value to prevent excess scarring/fibrosis in conjunctiva following trabeculectomy or in patients with severe conjunctival inflammation. 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.  (source: http://en.wikipedia.org/wiki/Tetrandrine).
