Dorsomorphin is an AMP-activated kinase (AMPK) inhibitor. Dorsomorphin selectively inhibits the bone morphogenetic protein (BMP) type I receptors ALK2, ALK3 and ALK6 and thus blocks BMP-mediated SMAD1/5/8 phosphorylation, target gene transcription and osteogenic differentiation. Dorsomorphin has shown to increase cisplatin-induced apoptosis, which was associated with hyper-induction of the tumor suppressor p53.
