IDE 2 (CAS 1136466-93-7): R&D Systems
Catalog Number: 4016
Chemical Name: Heptanedioic acid-1-(2-cyclopentylidenehydrazide)
Biological Activity
Cell-permeable inducer of definitive endoderm formation in mouse and human embryonic stem cells (ESCs) (EC50 = 223 nM for induction of Sox17 expression in ESCs). Reported to activate TGF-β signaling and downstream Smad2 phosphorylation; upregulates Nodal expression. Promotes pancreatic progenitor cell formation in vitro, and gut tube formation in vivo.
