Merck, P5499-25MG, Dorsomorphin

Dorsomorphin got its name due to its ability to induce dorsoventral patterning abnormalities in zebrafish, a characteristic trait of BMP-pathway mutant embryos. Structurally, dorsomorphin is identical to compound C. Dorsomorphin induces stem cell differentiation, suggesting potential therapeutic implications for fibrodysplasia ossificans progressiva (FOP), a progressive muscle and bone disease. Besides its BMP signaling inhibition, dorsomorphin also hinders the vascular endothelial growth factor (VEGF) type 2 receptor (FLK1/KDR) and disrupts angiogenesis during zebrafish development.
