Description
Novel AMP-activated protein kinase activators
[0001] The present invention relates to novel polyether compounds that have AMP-activated protein kinase activating activity and are useful for the prevention and / or treatment of diseases caused by decreased activity of AMP-activated protein kinase. The present invention also relates to pharmaceutical compositions containing the novel polyether compounds.
[0002] In recent years, it has become clear that hyperglycemia and hyperinsulinemia increase the risk of cancer cell development, proliferation, and recurrence, and one of the causes is insulin resistance. AMP-activated protein kinase (AMPK) has recently attracted attention as a factor that improves insulin resistance (Non-Patent Document 1).
[0003] AMPK is a type of serine-threonine kinase (serine-threonine phosphorylating enzyme) present in eukaryotic cells from humans to yeast, and plays an important role as an intracellular energy sensor. It is a protein kinase activated by AMP (adenosine monophosphate), which is generated when ATP (adenosine triphosphate) is used as energy. That is, AMPK is activated in response to an increase in AMP under conditions in which the intracellular ATP supply is depleted, such as low glucose, hypoxia, ischemia, and heat shock.
[0004] When AMPK is activated, the synthesis of sugars, fats, and proteins is suppressed, and the breakdown (catabolism) of sugars, fats, and proteins is promoted, resulting in the production of ATP, which has the same effect as exercise and is known to be effective in treating obesity and diabetes (Non-patent Document 2).
[0005] In recent years, it has been reported that metabolic syndrome, in which AMPK activity is reduced, is a risk factor for cancer, that AMPK activity is also suppressed in cancer cells, and that activating AMPK can suppress the proliferation of cancer cells. AMPK is therefore considered a promising target for the prevention and / or treatment of cancer (Non-Patent Document 3).
[0006] As AMPK activators, metformin, cordycepin, resveratrol, oleanolic acid, cryptotanshinone, berberine, etc. have been reported so far (Non-Patent Document 4).
[0007] Under these circumstances, there is a need for the development of novel AMPK activators as effective preventive and / or therapeutic agents not only for obesity and type 2 diabetes but also for cancer.
