Description

5-bromethiazole derivative, Preparation Method And The Use
Technical field
The present invention relates to the pharmaceutical field relevant with diabetes.Particularly, the present invention relates to dipeptidyl peptidase-iv inhibitor to the medicative 5-of the containing bromethiazole of diabetes structure and preparation method thereof, and the pharmaceutical composition that contains them.
Background technology
According to statistics, global diabetic subject in 2007 is nearly about 2.5 hundred million, and wherein exhausted big number is II type (being non-insulin-depending type) diabetic subjects.Antidiabetic medicine in clinical use mainly contains sulfonylurea, N1,N1-Dimethylbiguanide class and trypsin class medicine at present, the medicament of insulin sensitizer and the alpha-glucosidase inhibitor etc. in addition of listing in recent years.These medicines have good therapeutic action, but serious side effects such as ubiquity hypoglycemia, and there is safety issue in long-term treatment, as problems such as liver toxicity and weight increase.
DPP IV (dipeptidyl peptidase IV, DPP-IV) can be effectively and the glucagon-like peptide 1 (GLP-1) of degrading apace, GLP-1 is one of the most effective stimulant of insulin production and secretion, therefore suppress the effect that DPP-IV can strengthen endogenous GLP-1, thereby improve the level (CN200480017355.6) of Regular Insulin in the blood.Medical science has confirmed that the DPP-IV inhibitor is a kind of novel antidiabetic treatment medicine (Deacon C.F. at present, Holst J.J., Dipeptidyl Peptidase IV Inhibitors:A Promising NewTherapeutic Approach for the Management of Type 2 Diabetes.The InternationalJournal of Biochemistry ﹠amp; Cell Biology, 2006,38 (5-6): 831-844).Clinical effectiveness shows that such medicine has good hypoglycemic effect, untoward reaction things such as common weight increase of simultaneously not finding other diabetes medicaments and being produced and hypoglycemia.
The major structural types of existing DPP-IV inhibitor has: divides from the chemical structure type and mainly is divided into piperazine and triazole species, 2-cyano group-pyrrolidines, thiazolidines, Pyrimdinone, and the other types structure medicament.
The invention discloses the 5-bromethiazole class DPP-IV inhibitor that reduces plasma glucose levels very effectively, these compounds lay the foundation for the medicine that further can be used for the treatment of diabetes, particularly non insulin dependent diabetes.
