Tranilast is a compound that exhibits anti-inflammatory and immunomodulatory effects by inhibiting lipid mediator and cytokine release from inflammatory cells and interfering with PDGF- and TGF-β1-induced proliferation and migration of vascular medial smooth muscle cells. Tranilast suppresses production of prostaglandin D2 (IC50 = 0.1 mM)1, prostaglandin E2 (IC50 = ~1-20 µM), thromboxane B2 (IC50 = ~10-50 µM), TGF-β1 (IC50 = ~100-200 µM), and interleukin-8 (IC50 = ~100 µM) in in vitro models as well as attenuates of the proinflammatory activity of human monocytes.2 While originally marketed as an antiallergenic drug, the efficacy of tranilast in preventing restenosis after percutaneous coronary intervention has been tested in a large-scale clinical trial.3 Additionally, tranilast inhibits VEGF-induced angiogenetic activities (i.e., proliferation, migration and tube formation of vascular endothelial cells) with IC50 values of 22, 18 and 193 µM, which may prove therapeutic for various retinal diseases.4

Cayman Chemical Company regularly evaluates our shipping methods to ensure product stability is maintained and our corporate environmental impact is minimized. Products selected for review are evaluated and shipping methods are certified by our Scientists. While occasionally our method of shipping a product may change, rest assured the shipping conditions on all Cayman Chemical products have been reviewed and validated.
Upon receipt, it is important to check the storage requirements of your products and place them at the appropriate temperature. Products shipped without ice may require frozen storage for long term stability.
Cayman Chemical was formed over thirty years ago by demonstrating the value of naturally growing gorgonian corals as a renewable, economically viable source of prostaglandins. Today we operate our business knowing that we owe our start to the renewable resources our environment had provided. As Cayman Chemical continues to grow we consistently evaluate our business processes to ensure we are operating at the highest environmental standards.
