A-83-01

InformationA-83-01 is a potent inhibitor ofTGF-β type I receptor (ALK5-TD)with IC50 of 12 nM. A-83-01 also inhibits the transcription induced byactivin/nodal type I receptor (ALK4-TD)andnodal type I receptor (ALK7-TD)with IC50 of 45 nM and 7.5 nM, respectively.SolutIn vitroA-83-01 inhibits the transcriptional activity induced by TGF-β type I receptor ALK-5 and that by activin type IB receptor ALK-4 and nodal type I receptor ALK-7, the kinase domains of which are structurally highly related to those of ALK-5. A-83-01 is potent in the inhibition of ALK5 and also prevents phosphorylation of Smad2/3 and the growth inhibition induced by TGF-β.In vivoA83-01 treatment significantly increases the number of Nkx2.5+ cardiomyoblasts at baseline and after myocardial injury, resulting in an increase in newly formed cardiomyocytes. A83-01 treatment significantly improves ventricular elastance and stroke work, leading to improved contractility after injury.Cell Datacell lines：Concentrations：1 μMIncubation Time：1 hPowder Purity:.
