生物活性    
LDN-214117 is an orally active ALK2 inhibitor with well-tolerated and good brain penetration. LDN-214117 has a high selectivity and low cytotoxicity for ALK2 with an IC50 value of 24 nM. LDN-214117 also is a specific bone morphogenetic proteins (BMPs) signaling inhibitor and has relatively selective inhibition for BMP6 with an IC50 value of 100 nM. LDN-214117 can be used for the research of fibrodysplasia ossificans progressiva (FOP), diffuse intrinsic pontine glioma (DIPG) [1][2]

IC50 & Target    
IC50: 24 nM (ALK2); 27 nM (ALK1); 1,171 nM (ALK3); 3,000 nM (ALK5); 1,022 nM (BMP6); 27 nM (BMP2); 960 nM (BMP4); 16,000 nM (TGF-β1)[1]
