Biological Activity for RepSox
RepSox is a potent and selective inhibitor of the TGF-β type I receptor/ALK5 (IC50 values are 4 and 23 nM for TGF-β type I receptor autophosphorylation and binding respectively). Selective for TGF-β type I receptor over a range of kinases, including p38 MAPK, JNK1 and GSK3 (IC50 > 16 μM). Enhances the efficiency of cellular reprogramming; replaces Sox2 by inducing Nanog expression.
RepSox synthesized to Ancillary Material Grade also available.

Stem Cells Scientific Review
Written by Kirsty E. Clarke, Victoria B. Christie, Andy Whiting and Stefan A. Przyborski, this review provides an overview of the use of small molecules in the control of stem cell growth and differentiation. Key signaling pathways are highlighted, and the regulation of ES cell self-renewal and somatic cell reprogramming is discussed. Compounds available from Tocris are listed.
