Information
RepSox (E-616452, SJN 2511, ALK5 Inhibitor II) is a potent and selective inhibitor of theTGFβR-1/ALK5withIC50of 23 nM and 4 nM for ATP binding to ALK5 and ALK5 autophosphorylation in cell-free assays, respectively.
In vitro
RepSox inhibits ATP binding to ALK5 and ALK5 autophosphorylation with IC50 of 23 nM and 4 nM, respectively. RepSox inhibits TGF-β induced cellular PAI-1 luciferase activity with IC50 of 18 nM. RepSox is able to successfully replace Sox2 in reprogramming by inhibiting transforming growth factor-β (Tgf-β) signaling, which in turn induces Nanog expression. Effect of RepSox inducing reprogramming does not require chromatin remodeling. RepSox is found to be efficient at generating iPSCs.
In vivo
RepSox is able to be contribute to forming chimeric embryos in vivo when injected into blastocysts. A one-day treatment with RepSox is sufficient to replace transgenic Sox2.
