Embodiment 1

[0031] Preparation of Compound 1-10:

[0032] Dried seeds (20kg) of Cardamom grassa, crushed, extracted twice with 90% ethanol under reflux, each time for 2 hours, combined ethanol extracts, recovered ethanol under reduced pressure to obtain extract. The extract was dispersed in water and extracted with ethyl acetate, then concentrated to the ethyl acetate extract. Then the ethyl acetate extract (Fr.A, 1.5kg) was subjected to silica gel column chromatography, and methanol-chloroform (0:100, 2:98, 5:95, 10:90, 20:80 and 100:0, v / v) Eight fractions of Fr.A-1 to Fr.A-8 were obtained by gradient elution of the eluent. Fr.A-7 (50g) was obtained by MCI CHP 20P gel column chromatography (methanol-water, 30:70, 40:60, 50:50, 70:30, 100:0, v / v) to obtain Fr.A -7-1~Fr.A-7-6. Fr.A-7-2 (15g) was purified by silica gel column chromatography (MeOH-CHCl 3 , 10:90 and 20:80) obtained Fr.A-7-2a~Fr.A-7-2e. Fr.A-7-2c (5g) was purified by Sephadex LH-20 (chloroform-methanol, 50:50), silica g...

Abstract

The invention provides ten novel diaryl heptane dimers shown in a structural formula (I), namely katsumadainol C1-C10 1-10, a pharmaceutical composition with the katsumadainol C1-C10 as an active ingredient, and a preparation method and application of the two , and belongs to the technical field of medicines. Thedimers can significantly promote GLP-1 secretion, has GPa, PTP1B and alpha-glucosidase inhibitory activity, can form a pharmaceutical composition with a pharmaceutically acceptable carrier or excipient, and can be used for preparing hypoglycemic drugs or health food.

Description

Technical field: [0001] The invention belongs to the technical field of medicines. Specifically, 10 novel diarylheptane dimers, myristyl alcohol C 1 -C 10 (katsumadainols C 1 -C 10 , 1-10), with compound 1-10 as the pharmaceutical composition of active ingredient, their preparation method, and its application in the preparation of GLP-1 secretagogue medicine, in the preparation of GPa, PTP1B and α-glucosidase The application in inhibitor drugs, and the application in the preparation of hypoglycemic drugs or health food. Background technique: [0002] Type 2 diabetes (Type 2diabetes mellitus, T2DM), as a complex metabolic disease, has become a major global health problem. Due to long-term high blood sugar, type 2 diabetes often leads to serious complications, such as retinopathy, kidney disease, high blood pressure, etc. Currently, there are 7 oral hypoglycemic agents on the market, including biguanides, α-glucosidase inhibitors, insulin secretory agents, insulin sensit...
