- the invention also relates to a process for the manufacture of these novel compounds and medicaments containing them.
- the compounds of the invention have activation effect on AMP (adenosine monophosphate)-activated protein kinase, which results in lowered blood glucose and lipid levels.
- AMP adenosine monophosphate
- AMPK regulation diseases that are related to AMPK regulation, such as obesity, dyslipidemia, hyperglycemia, type 1 or type 2 diabetes, and cancers.
- Obesity and type 2 diabetes, hypertension and cardiovascular disease are diseases that feature serious disturbances in glucose or lipid metabolism that severely affect the health and quality of life of affected individuals.
- cancer metabolism is known to be different from normal cellular metabolism. The increasing prevalence of these diseases makes finding new drug targets for treating these syndromes an urgent task.
- AMP-activated protein kinase acts as a cellular energy sensor and regulator. It is activated by an increase in the cellular AMP:ATP ratio induced by metabolic stress, hormone and nutrient signals and other cellular mechanisms such as phosphorylation and protein-protein interaction. Once activated, AMPK switches on catabolic pathways that generate ATP and switches off ATP-consuming anabolic pathways by acute regulation of the activity of key enzymes in metabolism and chronic regulation of the expression of pivotal transcription factors (Hardie, DG. Nature reviews 8 (2007b), 774-785; Woods, A et al. Molecular and cellular biology 20 (2000), 6704-6711).
- Adiponectin stimulates glucose uptake and fatty acid oxidation in vitro by activation of AMPK. Furthermore, it exerts its hypoglycemic effect by decreasing PEPCK and G6Pase expression, whereas the administration of dominant negative al adenovirus reverses the effect in vivo (Yamauchi, T et al. Nature medicine 8 (2002), 1288-1295).
- AMPK a potential target for treating metabolic syndrome
- Rosiglitazone is traditionally considered to be a PPARy agonist and exerts its antidiabetic effects through differentiation of adipocytes (Semple, RK et al. The Journal of clinical investigation 116 (2006), 581-589). Recent findings indicate that AMPK may be involved in the antidiabetic effects of rosiglitazone (Brunmair, B et al. The Journal of biological chemistry 277 (2002), 25226-25232; Kadowaki, T et al. The Journal of clinical investigation 116(2006), 1784-1792).
- metformin an existing antidiabetic agent without a defined mechanism of action
- recent studies demonstrate that it could activate AMPK in vitro and in vivo by inhibiting complex I (El-Mir, MY et al. The Journal of biological chemistry 275 (2000), 223-228; Owen, MR et al. The Biochemical journal 348 Pt 3 (2000), 607-614; Zhou, G et al. The Journal of clinical investigation 108 (2001), 1167-1174), and the hypoglycemic effect could be blocked completely by knockout of its upstream kinase LKB1, confirming the key role of AMPK in mediating the antidiabetic effect of metformin (Shaw, RJ et al. Science (New York) N.Y. 310 (2005), 1642-1646).
