LDN-193189 is a cell-permeable, highly potent and selective BMP pathway inhibitor by inhibiting BMP type I receptors ALK2 (IC50=5 nM) and ALK3 (IC50=30 nM), but not ALK4, ALK5, and ALK7 (> 0.5 µM). It prevents Smad1, Smad5, and Smad8 phosphorylation. It is a useful tool compound to modulate stem cell differentiation (for example, neural differentiation of human ESC/iPSC in combination with SB431542). It was also used in animal models to treat FOP and ectopic ossification, as well as NSCLC lung cancer.
