Abstract
The invention relates to the field of relative drugs of 2-type diabetes, and particularly, relates to a PTP1B inhibitor containing structures of nicotinamide and piperidine, a preparation method thereof, and an application thereof in preparation of drugs for the 2-type diabetes.
Description
Technical field
The present invention relates to the pharmaceutical field of type ii diabetes treatment.More particularly, the present invention relates to medicative a kind of PTP1B inhibitor, its preparation method containing niacin hydroxyacyl amine and piperidine structure of type ii diabetes tool, and the purposes in pharmacy.
Background technology
Type ii diabetes is a kind of common metabolic disturbance diseases, it is characterized in that periphery produces resistant function to film island element, shows as Regular Insulin to be combined signal transduction afterwards with insulin receptor and to lack at molecular level.The phosphorylation level of proteolytic enzyme propylhomoserin is the important regulate factors of intracellular signal transduction, it is by proteolytic enzyme histidine kinase (protein tyrosine kinase, PTK) and proteolytic enzyme propylhomoserin Phosphoric acid esterase (protein tyrosine phosphatase, PTP) jointly regulate and control.Research in recent years finds, proteolytic enzyme propylhomoserin phosphatase 1 B can dephosphorylation proteolytic enzyme propylhomoserin, plays important negative regulation effect in Insulin signaling pathway.Knock out PTPIB gene, or use antisense core former times acid (ASO) to suppress the expression of PTP1B albumen and mRNA in body, not only can significantly improve the susceptibility of test mice to Regular Insulin, and obviously can reduce the ill probability of obesity.These researchs show, PTP1B likely becomes the novel targets for the treatment of type ii diabetes.
The invention discloses a kind of PTP1B inhibitor containing niacin hydroxyacyl amine and piperidine structure of novel structure, these compounds can be used for the medicine preparing treatment type ii diabetes.
Summary of the invention
An object of the present invention is to provide a kind of PTP1B inhibitor with the excellent activity of formula I.
Another object of the present invention is to provide the method that preparation has the compound of formula I.
The compound that another object of the present invention is to provide containing formula I is treating the application in type ii diabetes as effective constituent.
Now in conjunction with object of the present invention, content of the present invention is specifically described.
The compound that the present invention has formula I has following structural formula:
Formula I of the present invention is synthesized by following route:
Compound II per in the presence of a base with compound III generation substitution reaction, obtain compound IV; There is lower and compound V at DCC (N, N'-dicyclohexyl carbodiimide) and react in compound IV, obtains VI; The oxidation of oxidized dose of compound VI, obtains Compound I.Compound II per can prepare (Leon Katz according to literature method; Et al, Journal of Organic Chemistry, 1954,19,711).
Formula I of the present invention has the restraining effect of PTP1B, can be used as effective constituent for the preparation of type ii diabetes medicine.The activity of formula I of the present invention is verified by receptor binding assays.
Formula I of the present invention is effective in quite wide dosage range.The dosage that such as every day takes, within the scope of 1mg-1000mg/ people, is divided into once or administration for several times.The actual dosage taking formula I can be decided according to relevant situation by doctor.
