TGF-β Receptor
A 83-01 is an inhibitor of TGF-β type I receptor kinase (ALK5), activin type IB receptor (ALK4), and nodal type I receptor (ALK7) (IC50s = 12, 45, and 7.5 nM, respectively). It blocks the phosphorylation of SMAD2/3 and inhibits TGF-β-induced epithelial-to-mesenchymal transition.

1.Topical application of ALK5 inhibitor A-83-01 reduces burn wound contraction in rats by suppressing myofibroblast population.
Sun X1, Kim YH, Phan TN, Yang BS. Biosci Biotechnol Biochem. 2014;78(11):1805-12. doi: 10.1080/09168451.2014.932666. Epub 2014 Jul 10.
Burn scar contracture that follows the healing of deep dermal burns causes severe deformation and functional impairment. However, its current therapeutic interventions are limited with unsatisfactory outcomes. When we treated deep second-degree burns in rat skin with activin-like kinase 5 (ALK5) inhibitor A-83-01, it reduced wound contraction and enhanced the area of re-epithelialization so that the overall time for wound closing was not altered. In addition, it reduced myofibroblast population in the dermis of burn scar with a diminished deposition of its biomarker proteins such as α-SMA and collagen. Treatment of rat dermal fibroblast with A-83-01 inhibited transforming growth factor-β1 (TGF-β1)-dependent induction of α-SMA and collagen type I. Taken together, these results suggest that topical application of ALK5 inhibitor A-83-01 could be effective in preventing the contraction of burn wound without delaying the wound closure by virtue of its inhibitory activity against the TGF-β-induced increase of myofibroblast population.
