Sigma-Aldrich Dorsomorphin. ≥98% (HPLC), powder, AMPK inhibitor. 25 mg

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.[1]

Dorsomorphin has been used:

• as an inhibitor of adenosine monophosphate-activated protein kinase (AMPK) to find the effects of trans-resveratrol on lipid mobilization in 3T3-L1 (a murine cell line of adipocytes) cells[2]
• as an AMPK inhibitor, to indicate the involvement of AMPK/mTOR (mammalian target of rapamycin) pathway in LRG (liraglutide) -induced autophagy[3]
• in the induction step, employed in in vitro differentiation of Friedreich′s ataxia (FRDA) and induced pluripotent stem cells (iPSCs) to neurospheres and neurons using ES (embryonic stem cell) media[4]

BMP Inhibitor; Cell-permeable pyrrazolopyrimidine compound that acts as a potent, selective, reversible, and ATP-competitive inhibitor of AMPK (AMP-activated protein kinase; Ki = 109 nM in the presence of 5 μM ATP and the absence of AMP).

Dorsomorphin is a selective inhibitor of Bone morphogenetic protein (BMP) signaling. It has been found to inhibit BMP signals required for embryogenesis and promoted significant neural differentiation from human pluripotent stem cell (hPSC) lines. Dorsomorphin also acts as a potent, selective, reversible, and ATP-competitive inhibitor of AMPK (AMP-activated protein kinase); Ki = 109 nM in the presence of 5 μM ATP and the absence of AMP).
