Background

A 83-01 is a potent and selective inhibitor of TGF-β type I receptor ALK5 kinase, activin type IB receptor ALK4, and nodal type I receptor ALK7 with an IC50 value of 12, 45, and 7.5 nM, respectively (1). This small molecule has also been shown to inhibit Smad2/3 phosphorylation along with TGF-β-induced growth inhibition and induction of Twist and Wnt3 (1,2). A 83-01 can be used to stabilize rat induced pluripotent stem cell (riPSC) cultures by inhibiting spontaneous differentiation and increasing the clonal expansion efficiency (3).
