Biological Data

Biological description

LDN193189 hydrochloride is a potent and selective ALK2/ALK3 inhibitor (IC50 values are 5 and 30 nM) which inhibits BMP4-mediated Smad1/5/8 phosphorylation. It is a derivative of dorsomorphin.

LDN193189 is frequently used in stem cell research. It promotes differentiation of neural progenitor cells from hPSCs.

It may be used as a component for brain organoid production.
