Dorsomorphin (866405-64-3) is a potent, selective and ATP-competitive inhibitor of AMP-activated protein kinase (AMPK) (Ki = 109 nM).1 It displays no significant inhibition of ZAPK, SYK, PKCT, PKA and JAK3. It inhibits bone morphogenetic protein (BMP) type I receptors (ALK2, ALK3 and ALK6).2 Dorsomorphin has been shown to promote cardiomyogenesis in mouse embryonic stem cells (ESCs) in vitro.3 Dorsomorphin also induces autophagy in cancer cell lines via a mechanism independent of AMPK inhibition.4
