LDN193189 is a highly potent small molecule BMP inhibitor that inhibits BMP type I receptors ALK2 (IC50: 5 nM), ALK3 (IC50: 30 nM) and ALK6 (TGFβ1/BMP signaling) and subsequent SMAD phosphorylation.

LDN-193189 is a cell permeable small molecule inhibitor of bone morphogenetic protein (BMP) type I receptors ALK2 and ALK3 (IC50 = 5 nM and 30 nM respectively). LDN-193189 was derived from structure-activity relationship studies of Dorsomorphin and functions primarily through prevention of Smad1, Smad5, and Smad8 phosphorylation. LDN-193189 only weakly inhibits ALK4, ALK5, and ALK7. BMP signaling coordinates developmental patterning and has essential physiological roles in mature organisms. LDN-193189  has been used to reduce ectopic ossification in a mouse model of fibrodysplasia ossificans progressiva
