Research Area: Rheumatoid arthritis, Hyp Biological Activity: Tranilast (Rizaben) is an antiallergic drug for bronchial asthma. It has been used for the treatment of allergic disorders such as asthma, allergic rhinitis and atopic dermatitis. It has also been investigated for use as an antiproliferative drug on drug-eluting stents. [1]
Biochem/physiol Actions Tranilast is an anti-asthma drug, which inhibits LTC4 and PGE2 formation in stimulated monocytes, but does not inhibit cyclooxygenase or lipoxygenase activity; inhibits mast cell degranulation; inhibits VEGF-induced angiogenesis in vivo and also inhibits proliferation and tube formation of human endothelial cells in vitro. Tranilast may represent a new class of drugs for therapy to treat ongoing TH1-mediated autoimmune diseases.
