Abstract
The invention belongs to the field of medicinal compounds, and concretely discloses marine fungus-derived depside compounds and an application thereof in treatment of type 2 diabetes. The structure of the depside compounds is represented by formula (I). The compounds 1-6 can substantially inhibit the activity of alpha-glucosidase, the IC50 value of the compound 1 is 10.4[mu]M, the IC50 value of the compound 2 is 13.3[mu]M, the IC50 value of the compound 3 is 2.1[mu]M, the IC50 value of the compound 4 is 12.4[mu]M, the IC50 value of the compound 5 is 9.8[mu]M, and the IC50 value of the compound 6 is 11.7[mu]M, wherein the IC50 value of positive control acarbose is 553.7[mu]M. Kinetic researches of the alpha-glucosidaseinhibition effect show that the compounds 1, 3 and 5 are noncompetitive inhibitors. The compounds can be used for preparing alpha-glucosidase inhibitor medicines in order to prevent and treat the type 2 diabetes.
Description
Technical field
The present invention relates to medical compoundss field, and in particular to the medical compoundss in marine fungi source, more specifically, relating to
And one class marine fungi source depsidcs and its treatment type ii diabetes application.
Background technology
At present, the type ii diabetes number of patients in global range is more than 3.7 hundred million people, and the number of patient is also fast
Speed increases.The growth is reduced and other with economic development, aged tendency of population, increasingly urbanization, dietary habit change, physical exertion
Living-pattern preservation is relevant.Thus, type ii diabetes are considered as that 21 century world community public health security is most severe
One of challenge.In type ii diabetes, body can produce insulin, but because of insulin secretion relative deficiency or effect defect
(also referred to as insulin resistant), causes blood glucose rise.And alpha-glucosidase is a kind of important for the treatment of early stage type ii diabetes
Target.It is that a class can be from the total of the alpha-glucose-based enzyme of the non-reducing end catalyzing hydrolysis containing phlorose glycosidic bond substrate
Claim.Alpha-glucosidase is distributed widely in organism, participates in food digestion, the biosynthesiss of glycoprotein, and polysaccharide and sugar are compound
Many bioprocesss such as the synthesis of thing and catabolism.Alpha-glucosidase inhibitor is a class to delay intestinal carbohydrate
Absorb and reach the oral antidiabetic drug for the treatment of diabetes, its action principle is:Competitive inhibition is located at the various α-Fructus Vitis viniferaes of small intestinal
Glycosidase, slows down the speed for being decomposed into glucose, so as to slow down the absorption of glucose in intestinal, improves the height of post-prandial glycemia
Peak.Research confirms that alpha-glucosidase inhibitor can prevent and treat post prandial hyperglycemia and alleviate hyperinsulinemia, while can be with
Improve carbohydrate tolerance.Currently, the alpha-glucosidase inhibitor of clinical application mainly has Acarbose and voglibose.In order to keep away
Exempt from or reduce the adverse side effect or drug resistance of current medical, while providing more drug candidates, therefore find new α-Fructus Vitis viniferae
Glycosidase inhibitor and to develop into medicine be very necessary.
The content of the invention
Present invention aims to the defect that at present type ii diabetes medicine is present, there is provided a class marine fungi
The depsidcs in source.
It is a further object to provide the preparation method of the depsidcs in class marine fungi source.
The depsidcs for being to provide class marine fungi source in a purpose of the present invention are preparing treatment II
Application in patients with type Ⅰ DM medicine.
To achieve these goals, the present invention is achieved by the following technical programs:
The depsidcs in one class marine fungi source, its structural formula is as shown in formula I:
