A cell-permeable, potent, and highly selective BMPR (bone morphogenetic protein receptor) inhibitior (IC₅₀ against human ALK2/BMPR-I = 107.9 nM) that exhibits no inhibitory activity against ALK5, AMPK, FLK1/KDR/VEGRF2, or PDGFRβ. Effectively blocks ALK2- and ALK3-, but not ALK6-, mediated transcription activity (IC₅₀<500 nM, <100 nM, and >10 M in reporter assays using C2C12BRA expressing constitutively active ALK2, ALK3, or ALK6, respectively). Comparing to its non-BMPR-selective structural analog dorsomorphin, DMH1 is 12.5-times more potent in preventing BMP pathway-dependent DV (dorsoventral) development (EC₁₀₀ = 0.2 M DMH1 or 2.5 M DM) in zebrafish embryo in vivo, while being non-toxic to the fish embryo and exhibiting no effect against VEGF signaling-dependent intersomitic vessel (ISV) formation even at concentrations as high as 50 M.
