Biological Activity

Description Dorsomorphin is a potent, reversible, selective AMPK inhibitor with Ki of 109 nM in cell-free assays, exhibiting no significant inhibition of several structurally related kinases including ZAPK, SYK, PKCθ, PKA, and JAK3. Dorsomorphin selectively inhibits the BMP type I receptors ALK2, ALK3 and ALK6. Dorsomorphin is used in promoting specific cell differentiation and inducing cancer cell line autophagy. For cell testing, the water-soluble S7306 Dorsomorphin (Compound C) 2HCl is recommended.
Targets
ALK2 [3] ALK3 [3] ALK6 [3] AMPK [1]
(Cell-free assay)
109 nM(Ki)
In vitro

Dorsomorphin inhibits ACC inactivation by either AICAR, and also attenuates AICAR’s effect to increase fatty acid oxidation or suppress lipogenic genes in hepatocytes. [1]

Inhibition of AMPK activity by Dorsomorphin almost completely inhibits autophagic proteolysis in HT-29 cells. [2]

In addition, Dorsomorphin selectively inhibits the BMP type I receptors ALK2, ALK3 and ALK6, and thus blocks BMP-mediated SMAD1/5/8 phosphorylation, target gene transcription and osteogenic differentiation. [3]
In vivo

Dorsomorphin (10 mg/kg) reduces basal levels of hepcidin expression and increases serum iron concentrations in adult mice. [3]

Dorsomorphin (0.2 mg/kg, i.v.) significantly reduces VCAM-1 and ICAM-1 expression in the thoracic aorta of LPS-treated rats. [4]

Protocol (from reference)

Kinase Assay:

[1]
  • AMPK partial purification and in vitro kinase assay.

    Liver AMPK is partially purified from male SD rats to the blue-Sepharose step. The 100-μl reaction mixture contains 100 μM AMP, 100 μM ATP (0.5 μCi 33P-ATP per reaction), and 50 μM SAMS in a buffer (40 mM HEPES, pH 7.0, 80 mM NaCl, 0.8 mM EDTA, 5 mM MgCl2, 0.025% BSA, and 0.8 mM DTT). The reaction is initiated with addition of the enzyme. After 30-minute incubation at 30°C, the reaction is stopped by addition of 80 μl 1% H3PO4. Aliquots (100 μl) are transferred to 96-well MultiScreen plates. The plate is washed three times with 1% H3PO4 followed by detection in a Top-count. The in vitro AMPK inhibition data obtained with compound C — (6-[4-(2-Piperidin-1-yl-ethoxy)-phenyl)]-3-pyridin-4-yl-pyyrazolo[1,5-a] pyrimidine — are fit to the following equation for competitive inhibition by nonlinear regression using a least-squares Marquardt algorithm in a computer program written by N. Thornberry of Merck Research Laboratories: Vi/Vo = (Km + S)/[S + Km × (1 + I/Ki)], where Vi is the inhibited velocity, Vo is the initial velocity, S is the substrate (ATP) concentration, Km is the Michaelis constant for ATP, I is the inhibitor (compound C) concentration, and Ki is the dissociation constant for compound C.

Customer Product Validation

<p>FGF21 activates myogenic and aerobic myofiber-associated genes expression via AMPK pathway. The activator (acadesine) or inhibitor (dorsomorphin) of AMPK pathway were used to treat the pcDNA3.1-21 or control transfected C2C12 myoblasts. For this experiment, four groups were set up: FGF21-ACA (pcDNA3.1-21‡acadesine), Control-ACA (control‡acadesine), FGF21-DOR (pcDNA3.1-21‡dorsomorphin), and Control-DOR(control‡dorsomorphin). The qRT-PCR was performed to detect the genes expression of FGF21 (A), AMPK (B), Sirt 1, Myoglobin(C), Desmin (D), MEF2c (E), a-actin (F). (G) The C2C12 myoblasts were transiently transfected with pCDNA3.1-21 or pCDNA3.1, Western blot showed FGF21 activated AMPK signal via FGF21-Sirt1-AMPK. For the phosphorylated AMPK (right), the intensity of band was normalized total AMPK, and then normalized by control. (H and I) FGF21, as well as AMPK activator acadesine (ACA), increased phosphorylation of AMPM, and myogenic genes expression, especially MyHC I, which was activated by ACA (FGF21‡ACA) and suppressed by AMPK inhibitor DOR(FGF21‡DOR). The data are presented as mean±SD (*P<0.05, **P<0.01, and P<0.001), n=ˆ3.</p>

<p>Effects of BMP-7 and downstream pathways on the protectiveeffect of OGDPC against OGD/R in SH-SY5Y cells. BMP-7 was blockedby Noggin (200 ng/mL), MAPK signal was blocked by U0126 andSB203580 mixture (10 μmol/L each) and Smad signal was blocked byDorsomorphin (1 μmol/L) and Smad 1 RNAi. BMP-7 blockage com-pletely inhibited the protective effect of OGDPC as represented by (a)decreasing cell viability and (b) increasing LDH activity to the level of OGD/R treatment. MAPK and Smad blockage could partly inhibit theprotective effect. Values are presented as mean±standard deviation (SD)(n = 3). **P < 0.01 compared with control group;##P < 0.01 comparedwith OGD/R group;§§P < 0.01 compared with OGDPC group.
