Abstract
A compound represented by the following general formula (1): [wherein m is an integer of 0 to 4; n is an integer of 5 to 9; and W represents -CH(OR)- (R represents hydrogen or a hydroxy-protecting group) or -C(=O)-], a salt of the compound, or an ester of the compound. The compound, salt, or ester is effective in blood sugar depression, plasma insulin reduction, and triglyceride reduction and is useful for the prevention of and/or treatments for diabetes, complications of diabetes, hyperlipemia, etc.
Description
Technical field
The present invention relates to a kind of demonstrate strong blood sugar reduction effect, plasma insulin reduction effect and glyceryl ester reduction effect, and be not attended by weight increase and carboxylic acid cpd fat, that can prevent and/or treat diseases such as diabetes, diabetic complication, high fat of blood, arteriosclerosis, and the medicine that contains this carboxylic acid cpd.
Background technology
Diabetes are the metabolic diseases that produced by multiple reason, are divided into 1 type of hypoinsulinism or follow 2 types of the insulin sensitivity reduction of tip tissue.Diabetes B is a background with environmental factorss such as fat and overfeedings, sharply increases in recent years, it is said that world's onset diabetes rate is 5%.
Regular Insulin and the sulfonylureas of using in the medication of Diabetes Mellifus more, but hypoglycemia and sulfonylurea caused because liver fatigue and secondary is invalid as its side effect meeting.Biguanides has been improved insulin sensitivity, has corrected hyperglycemia reluctantly, but the situation of bringing out lactic acidosis is arranged.Kai Fa thiazole methane series Remedies for diabetes it is said and has the effect (expert opinion of drug research of improving the tip insulin resistance in recent years, 9, pp1347-1361,2000), and can not cause hypoglycemia, controlling blood sugar still claims that as the side effect report liver is had severe impairment etc. well.Therefore, expect to have the medicine that improves insulin resistance of non-thiazole methane series.
On the other hand, as the compound of non-thiazole methane series, 2,2-dichloro alkanoic acid compound exhibits goes out to reduce the blood glucose value of diabetes type animal, reduces plasma insulin and reduce the effect of plasma glycerol ester simultaneously, these be known (European drug chemistry periodical, 33, pp775-787,1998).Insulism shows as insulin resistance, and high fat of blood conduct and diabetes complicated metabolism of fat have arteriosclerotic danger unusually.Thereby overcoming these problems is the keys that prevent and/or treat diabetes and diabetic complication.
For example, following compd A is to show antidiabetic effect to various animal-types (European drug chemistry periodical, 33, pp.775-787, the compound 3e of record in 1998; Metabolism, 48, pp34-40,1999), it is renderd a service surpasses the thiazolidine based compound.And, because do not show the mechanism of action PPAR γ activation (toxicology archives, 73, pp440-450,1999) of thiazolidine based compound, obviously showing the effect different with the thiazolidine based compound, expectation is about alleviating the compound of side effect.
Summary of the invention
In order effectively to treat diabetes and diabetic complication, except alleviating, avoid purposes such as side effect, want easy controlling blood sugar value, avoid the drug interaction used together with other reagent, expect more highly active compound or have under the low consumption equal or equal more than active compound.
According to this viewpoint, lack and have equal or equal above active compound than the higher compound of compd A activity or amount ratio compd A and expect that it is useful to preventing and/or treating diabetes and diabetic complication and high fat of blood and arteriosclerosis.
Thus, the inventor studies in order to find more highly active compound, the carboxylic acid cpd that found that following general formula (1) expression has strong blood sugar reduction effect, can not follow weight increase and obesity, the useful conduct of energy prevents and/or treats the medicine of diabetes, diabetic complication, high fat of blood, arteriosclerosis etc.The present invention is based on above-mentioned discovery finishes.
