Technical Field

The invention relates to the technical field of medicinal chemistry, in particular to novel p-coumaric acid sulfonate derivatives and a preparation method and application thereof.

Background

P-coumaric acid is an important hydroxycinnamic acid compound and has been reported to have activities of resisting oxidation, resisting bacteria, treating cardiovascular diseases and the like. At present, the production method of coumaric acid mainly comprises chemical synthesis, natural extraction, biotransformation and the like, the risk of environmental pollution caused by coumaric acid and the stability of coumaric acid serving as a production source are comprehensively considered, and the natural extraction method is the technical means which most accords with the concepts of environmental protection and quality control. Sulfonate derivatization is a feasible scheme in drug modification, has positive effect on drug attribute improvement, and is common sulfonate drugs such as busulfan, sulfonate mucopolysaccharide and the like.

The spartina alterniflora is a perennial high-stalk herbaceous plant of gramineae, is introduced into China by professor Zhongchong letter of Nanjing university at the end of 1979, and is successfully introduced into coastal areas of China in 80-90 years of the 20 th century, thereby making great contribution to beach protection and silt promotion and land building in coastal areas of China. But its growth spread has also affected the biodiversity and ecological environment of some coastal areas. Because the plants are higher and the yield is higher, the traditional treatment means such as harvesting and the like need to invest certain cost, the resource utilization of the spartina alterniflora is realized, the raw materials are stably produced by a natural extraction method, and then functional molecules with potential medicinal activity are developed, so that the huge economic benefit can be generated, and the good ecological effect can be brought. Taking scientific researchers in halophyte laboratories of Nanjing university as a representative, the edibility of the spartina alterniflora extract (new resource food of Ministry of health, Weixin food Standard No. 94, No. 06) has been solved internationally at present.

At present, a novel p-coumaric acid sulfonate derivative for realizing the resource utilization of spartina anglica and a preparation method and application thereof are lacked.

Disclosure of Invention

The invention aims to provide novel p-coumaric acid sulfonate derivatives for realizing the resource utilization of spartina anglica, and a preparation method and application thereof.

The technical scheme of the invention is as follows: the structural formula of the novel p-coumaric acid sulfonate derivative is shown as the formula (I):

furthermore, the volume ratio of the acetone to the ethanol is 1: 5.

Further, the extracting agent is ethyl acetate or dichloromethane.

Further, the number of washing times of the saturated sodium chloride solution is 3 or more.

The invention relates to application of a novel p-coumaric acid sulfonate derivative in spartina alterniflora resource utilization. As the spartina alterniflora is generally considered as an invasive species, the spartina alterniflora is not used for extraction and also needs to be managed and controlled; the raw materials and products are obtained by a natural extraction method, so that the spartina alterniflora is recycled, and the property of changing waste into valuable is achieved.

The invention relates to application of a novel p-coumaric acid sulfonate derivative in preparation of a medicament.

Has the advantages that: the preparation raw material of the coumaric acid sulfonate derivative can be obtained by a natural extraction method, and has a positive effect on realizing resource utilization of spartina alterniflora. The obtained p-coumaric acid sulfonate derivative has potential pharmaceutical activity. Sulfonate derivatization is a feasible scheme in drug modification, and has a positive effect on the improvement of drug properties.
