LDN193189 (4HCl)
Small Molecules for Stem Cell Research
LDN193189 (HCl) is a highly-potent inhibitor of BMP signaling, specifically blocking ALK1 (IC50 of 0.8 nM), ALK2 (IC50 of 0.8 nM), ALK3 (IC50 of 5.3 nM), and ALK6 (IC50 of 16.7 nM), and in turn affecting Smad1/5/8 expression (Galvin-Burgess, et al.). LDN193189 (HCl) has been shown to contribute to the differentiation of pluripotent stem cells (PSCs) into functional pancreatic beta cells when combined with CHIR99021, SANT-1, Y27632, Compound E, RepSox, Triiodothyronine Salt along with other growth factors (Pagliuca, et al.). LDN193189 has also been utilized in the derivation of neural progenitor cells (Edri, et al.), and cortical neurons (Qi, et al.) from PSCs.
