Description
Technical field
The present invention relates to the drug world related to diabetes.Specifically, the present invention relates to there is treatment to make to diabetes
Dipeptidyl peptidase-iv inhibitor containing cyclohexane-carboxylic acid amide structure and preparation method thereof, the drug regimen containing them
Thing and the medicine in terms for the treatment of diabetes.
Background technology
According to statistics, global diabetic about 2.5 hundred million or so in 2007, wherein number big absolutely is II types (i.e. non-pancreas
Island element dependent form) diabetic.At present the antidiabetic medicine in Clinical practice mainly have sulfonylurea, melbine class and
Trypsin class medicine, what is listed in recent years also have medicament of insulin sensitizer and Alpha-glucosidase inhibitor etc..These medicines
With good therapeutic effect, but the serious side effects such as generally existing hypoglycemia, and there is safety issue in long-term treatment, such as
The problems such as hepatotoxicity wind agitation and increased weight.
DPP IV (dipeptidyl peptidase IV, DPP-IV) can effectively and pancreas of rapidly degrading is high
Blood sugar element sample peptide 1 (GLP-1), GLP-1 are one of insulin production and the maximally effective stimulant of secretion, therefore suppress DPP-IV energy
Strengthen the effect of endogenous GLP-1, so as to improve the level of insulin in blood.Medical science has confirmed DPP-IV inhibitor at present
It is a kind of new antidiabetic treatment medicine, there are multiple medicine list marketings at present.Clinical effectiveness shows such medicine
With good hypoglycemic effect, while not finding that common increased weight and hypoglycemia produced by other diabetes medicaments etc. are bad
Reactant.
