[0071] Preparation Example 1 Preparation of Compound 2

[0072] (1) Preparation of 6-hydroxy-7-dimethoxycoumarin (2a)

[0073] For convenience, M in the following structural formula represents Me, that is, methyl.

[0074]

[0075] Methoxychloromethane (0.443mL, 5.84mmol) was added to aescin (520.5mg, 2.92mmol) and potassium carbonate (605mg, 4.38mmol) in N,N-dimethylformamide (14.6mL) solution, and After stirring for 13 hours at -20°C, the reaction solution was diluted with 10 mL of water, and then 1 equivalent of hydrochloric acid was added dropwise at 0°C until the solution changed from yellow to colorless. The aqueous layer was extracted with ethyl acetate (2×10 mL), the organic layers were combined, washed with saturated brine (10 mL), dried over anhydrous sodium sulfate, and evaporated to dryness under reduced pressure. The residue was subjected to silica gel column chromatography (petroleum ether: ethyl acetate = 9: 2 elution) to obtain compound 2a as a yellow solid.

Abstract

The invention provides a linear furocoumarin derivate with a structure expressed by formula 1, a method for preparing the same, an application of the linear furocoumarin derivate and a drug composition containing the linear furocoumarin derivate. The linear furocoumarin derivate has an activating function to GLUT4 membrane transfer and protein expression, and can be used as drugs for treating diabetes mellitus and complicating diseases of the diabetes mellitus.

Description

Technical field [0001] The present invention relates to the field of medicinal chemistry. Specifically, the present invention relates to a new class of linear furanocoumarin derivatives, preparation methods and uses thereof, and pharmaceutical compositions containing the derivatives. The linear furanocoumarin derivative has an agonistic effect on GLUT4 membrane transfer and protein expression, and can be used as a medicine for treating diabetes and its complications. Background technique [0002] Diabetes (diabetes mellitus) is a group of clinical syndromes caused by the interaction of genetic and environmental factors, due to absolute or relative insufficient insulin secretion and decreased sensitivity of target tissue cells to insulin, causing sugar, protein, fat, water and electrolytes, etc. A series of metabolic disorders. Clinically, hyperglycemia is the main common sign. Prolonged illness can cause multiple system damages. Acute metabolic disorders such as ketoacidosis can ...
