Definitions
- the present invention relates to a darcokinase activator containing a heterocyclic substituted benzimidazole derivative as an active ingredient. Further, the present invention relates to a novel heterocyclic substituted benzimidazole derivative.
- Glucokinase (ATP: D— hexo se 6— pho s pho tr an sf e. Raze, EC 2. 7. 1. 1) is one of four mammalian hexokinases ( Hexokinase IV). Hexokinase is the first stage enzyme in glycolysis and catalyzes the reaction from glucose to glucose 6-phosphate. Darcokinase is mainly expressed in liver and knee beta cells, and plays an important role in glucose metabolism throughout the body by controlling the rate-limiting step of glucose metabolism in these cells. Dalcokinase from the liver and i visceral cells has different N-terminal 15 amino acid sequences due to splicing differences, but the enzymatic properties are the same.
- darcokinase works as a glucose sensor in humans and plays an important role in glucose homeostasis.
- blood glucose control using the dalcokinase sensor system is considered to be possible in many patients with type I diabetes.
- the darcokinase activator is expected to be effective as a therapeutic agent for patients with type I diabetes because it can be expected to promote insulin secretion in the kidney cells and enhance glucose uptake and glucose release in the liver.
- pancreatic beta cell type dalcokinase has been applied to the brain of the rat, especially the feeding center.
- VHM's darucose concentration sensing system is presumed to have a dalcokinase-mediated mechanism similar to that of insulin secretion by visceral cells. Therefore, in addition to liver and knee pancreatic cells, VHM dalcokinase activity can be corrected not only for blood glucose correction but also for obesity, which is a problem in many type II diabetic patients. There is sex.
- a compound having a darcokinase activating effect is used as a therapeutic agent and / or a preventive agent for diabetes, or chronic complication of diabetes such as retinopathy, nephropathy, neurosis, ischemic heart disease, arteriosclerosis Treatment and treatment And / or as a preventive agent, and as a therapeutic and / or prophylactic agent for obesity.
- the compound represented by the above formula is common to the compound according to the present invention in that it has one pyrrole group and pyridine, but the basic skeleton of the above compound is 2,3-d] pyrimidine skeleton, which is different from the basic skeleton according to the present invention. Furthermore, the target diseases possessed by the above formula are subarachnoid hemorrhage and subsequent ischemic stroke, and are different from the target diseases of the compound according to the present invention.
- An object of the present invention is to provide a therapeutic and / or preventive agent for diabetes that binds to dalcokinase and increases the activity of darcokinase, and activates dalcokinase to It is to provide an anti-obesity agent that acts by stimulating.
- the present inventors have intensively studied to develop a novel anti-diabetic drug having a new medicinal effect and an effect higher than that of the existing anti-diabetic drug by an action different from that of the above-described existing drug.
- the inventors have found that the compound represented by (I) has a darcokinase activating action, and have completed the present invention. That is, the present invention
