Mechanism of Action

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. This compound (3-300 mM) suppresses the collagen synthesis of fibroblasts from keloid and hypertrophic scar tissue but not healthy skin fibroblasts. It (30-300 mM) inhibits the release of transforming growth factor (TGF)-beta 1 from keloid fibroblasts, which enhances the collagen synthesis of keloid fibroblasts. This drug improves keloids and hypertrophic scars which originate from the abnormal proliferation and excessive collagen accumulation of fibroblasts. It inhibits the release of TGF-beta 1, IL-1 beta and PGE2 from the human monocytes-macrophages. This chemical 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. It exhibits inhibitory effects on spontaneous collagen synthesis and TGF-beta 1-induced collagen and glycosaminoglycan synthesis.
In vivo	Tranilast results in a 58% reduction in TGF-beta1-induced 3[H]-hydroxyproline incorporation in the diabetic heart of rats. This compound attenuates cardiac fibrosis by 37% in association with reduction in phospho-Smad2 in the diabetic heart of rats. It 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.
