Abstract
The present invention relates to the drug world relevant to diabetes.Specifically, the present invention relates to a kind of inhibitors of dipeptidyl IV containing nitro amantadine tetrazole structure and preparation method thereof, and the application in terms of preparing diabetes medicament.
Description
Technical field
The present invention relates to the drug world relevant to diabetes.Specifically, the present invention relates to diabetes
The dipeptidyl peptidase-iv inhibitor of medicative a kind of nitro diamantane (obsolete) tetrazole structure and preparation side thereof
Method, containing they pharmaceutical composition and treatment diabetes in terms of medicine.
Background technology
According to statistics, global diabetics about about 2.5 hundred million in 2007, wherein the biggest number is II type
(i.e. non-insulin-depending type) diabetics.Antidiabetic medicine at Clinical practice mainly has sulfonylureas at present
Class, metformin class and trypsin class medicine, list in recent years also have medicament of insulin sensitizer and α-
Alpha-glucosidase inhibitors etc..These medicines have good therapeutic effect, but generally there is the serious pairs such as hypoglycemia
Effect, and there is safety issue in long-term treatment, such as problems such as liver toxicity and body weight increases.
DPP IV (dipeptidyl peptidase IV, DPP-IV) can effectively and pancreas of degrading rapidly
Glucagon-like peptide 1 (GLP-1), GLP-1 is insulin production and secretes one of maximally effective stimulant, therefore
Suppression DPP-IV can strengthen the effect of endogenous GLP-1, thus improves the level of insulin in blood.Doctor at present
Learning and it turned out DPP-IV inhibitor is a kind of novel antidiabetic treatment medicine, has had multiple medicine
Thing list marketing.Clinical effectiveness shows that such medicine has good hypoglycemic effect, does not finds other glycosurias simultaneously
The untoward reaction thing such as the increase of common body weight and hypoglycemia produced by medicine.
The major structural types of existing DPP-IV inhibitor has: chemically structure type divides and is broadly divided into piperazine
Piperazine triazole type, 2-cyano-pyrolidin class, thiazolidines, Pyrimdinone, and other types structure medicament.
The invention discloses the DPP-IV inhibitor of a kind of nitro diamantane (obsolete) tetrazole structure, these chemical combination
Thing may be used for the medicine of preparation treatment diabetes.
Summary of the invention
It is an object of the present invention to provide one and there is excellent activity, have Formulas I structure compound and
Its pharmaceutically acceptable salt.
It is a further object to provide preparation and there is the compound of Formulas I structure and the method for salt thereof.
In conjunction with the purpose of the present invention, present invention is specifically described.
The present invention has the compound of Formulas I structure and has a following structural formula:
Compound of formula I of the present invention is synthesized by following steps:
Compound II and bromoacetyl bromide III reacts in the presence of a base and obtains compound IV, the latter and 2H-tetra-
Nitrogen azoles-5-formic acid V reacts in the presence of a base and obtains compound VI, compound VI with in the presence of condensing agent with
VII reacts, and obtains compound I；Above-mentioned condensing agent includes N, N'-dicyclohexyl carbodiimide (DCC), N-
Ethyl-N'-(3-dimethylamino-propyl) carbodiimide hydrochloride (EDC) and carbonyl dimidazoles (CDI) etc., these contractings
Mixture can be used in combination with organic base, such as triethylamine, diisopropyl ethyl amine (DIPEA) and 4-dimethylamino
Pyridine (DMAP) etc..
The pharmaceutically acceptable salt of compound of formula I of the present invention includes, but are not limited to inorganic with various
Acid, such as, hydrochloric acid, sulphuric acid, nitric acid, phosphoric acid etc., or organic acid, such as formic acid, acetic acid, citric acid,
