Example Embodiment

[0041] Example 1: Preparation of DHA-PC(2) compound (2a), the structural formula of compound (2a) is:

[0042]

[0043] Mix 12mmol of polyunsaturated fatty acid and 10mmol of phosphorylated ethanolamine, and slowly drop the ester condensing agent, which includes 1.4mL DMF, 3.6mL Et 3 N and 1.2mL (COCl) 2 The mixed solution of 30mL dichloromethane was stirred at 0°C for 2h. After the reaction, the reaction solution was added with saturated sodium carbonate solution (100mL), extracted twice with dichloromethane (50mL), dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The crude product was quickly purified by silica gel column chromatography (V Ethyl acetate : V Petroleum ether = 1:2), purified to obtain a yellow viscous product. Agilent XDB-C18ZORBAX high performance liquid chromatography for further purification, room temperature, mobile phase (V Methanol : V water =95:5), flow rate 20ml / min, collection retention time t 1 / 2 =6.1min comp...

Abstract

The invention discloses a polyunsaturated fatty acyl phosphatide derivative and a preparation method and application thereof, the structural formula of the derivative is shown in the specification, wherein m = 5 or 6; n = 2, 3 or 5; k = 2, 3, 4, 5 or 6; and the polyunsaturated fatty acyl phosphatide derivative is prepared by evenly mixing polyunsaturated fatty acid and phosphoryl alcohol amine under the action of an ester condensation agent. The polyunsaturated fatty acyl phosphatide derivative not only can inhibit fat absorption, promotes the function of fat hydrolysis, but also can promote the fat hydrolysis and prevent fat accumulation, meanwhile does not affect the patient's appetite, and can be developed into drugs for reducing blood fat, regulating eating disorders, treating nutritional diseases such as being overweight or obese and the like.

Description

technical field [0001] The present invention relates to a series of derivatives of compounds, in particular to a polyunsaturated fatty acyl phospholipid derivative and its preparation method and application, and the series of polyunsaturated fatty acyl phospholipid derivatives are used in the preparation of drugs for regulating blood lipids, Applications in health care products or food. Background technique [0002] The improvement of material living conditions and the change of lifestyle have led to an increase in the incidence of hyperlipidemia year by year, and nutritional and metabolic diseases caused by hyperlipidemia, such as dyslipidemia and atherosclerosis, have become serious threats to human health. A class of diseases. According to a survey report on obesity in various countries released by the World Health Organization, the report shows that at least 1.6 billion people in the world are overweight or obese. [0003] Phospholipids (PC) are a class of phospholipid...
