Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
7.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 140 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Tranilast is an antiallergic drug by inhibiting lipid mediator and cytokine release from inflammatory cells, used for the treatment of allergic disorders such as asthma, allergic rhinitis and atopic dermatitis.
In vitro Tranilast is an anti-allergic drug inhibiting the release of substances such as histamine and prostaglandins from mast cells, which suppresses collagen synthesis of fibroblasts derived from keloid tissues. Tranilast (3-300 mM) suppresses the collagen synthesis of fibroblasts from keloid and hypertrophic scar tissue but not healthy skin fibroblasts. Tranilast (30-300 mM) inhibits the release of transforming growth factor (TGF)-beta 1 from keloid fibroblasts, which enhances the collagen synthesis of keloid fibroblasts. [1] Tranilast improves keloids and hypertrophic scars which originate from the abnormal proliferation and excessive collagen accumulation of fibroblasts. Tranilast inhibits the release of TGF-beta 1, IL-1 beta and PGE2 from the human monocytes-macrophages. [2] Tranilast inhibits the proliferation stimulated with fetal bovine serum (FBS), TGF-beta 1 and platelet-derived growth factor-BB (PDGF-BB) as well as PDGF-BB-induced migration. Tranilast exhibits inhibitory effects on spontaneous collagen synthesis and TGF-beta 1-induced collagen and glycosaminoglycan synthesis. [3]
In vivo Tranilast results in a 58% reduction in TGF-beta1-induced 3[H]-hydroxyproline incorporation in the diabetic heart of rats. Tranilast attenuates cardiac fibrosis by 37% in association with reduction in phospho-Smad2 in the diabetic heart of rats. [4] Tranilast treatment completely prevents the increase in chymaselike activity, reduces the chymase mRNA levels by 43%, and decreases the carotid intima/media ratio by 63% in the carotid artery of dogs.
