Description
Highly efficient, selective and reversible AMPK inhibitor (Ki = 109 nM). Inhibits AICAR and metformin-induced AMPK activation.It also exhibits activity in ALK2, ALK3 and ALK6. It also promote cardiomyocyte differentiation in mouse embryonic stem cells (mESCs).

Assay Description
Dorsomorphin (Compound C) (0-10 μM, 18 h) inhibited 2DG-induced GRP78 promoter activity in human fibrosarcoma HT1080 cells in a dose-dependent manner, but had little effect on GRP78 promoter activity induced by tunicamycin. Dorsomorphin (Compound C) C also inhibits GRP78 promoter activity caused by glucose withdrawal. Dorsomorphin (Compound C) has no effect on 2DG-induced PERK activation in HT1080 cells, and reduces basal and 2DG-induced AMPK phosphorylation levels [1].
Assay Type
Western Blot Analysis
Cell Line
Human fibrosarcoma HT1080 cells.
Concentration
0-10 μM
Incubation Time
18 hours
Result
In a dose-dependent manner, 2DG-induced GRP78 promoter activity was inhibited, and glucose withdrawal-induced GRP78 promoter activity was also inhibited.

Assay Description
Dorsomorphin (Compound C: 10 mg/kg, once intravenously) treatment can lead to a 60% increase in total serum iron levels in adult mice, reduce the basal level of hepcidin, and increase serum iron levels [1].
Dorsomorphin (Compound C: 0.2 mg/kg, intravenously 30 minutes before LPS injection) can reduce the expression of ICAM-1 and VCAM-1 in the aorta of LPS-injected rats [2].
Compared with animals stimulated with LPS only, treatment with Dorsomorphin (Compound C; 25 mg/kg; i.p. injection, in male BALB/c mice) before lipopolysaccharide (LPS) injection significantly reduced the lethality.
Animal Model
Wild-type (WT) C57BL/6 adult mice fed a standard iron supplemented diet express high levels of hepcidin
Dosage
10 mg/kg
Administration
Intravenously once.
Result
Increase serum total iron concentration by 60%. Effectively reduce the basal level of heparin expression in adult mice and increase serum iron concentration.
