Description

A kind of preparation method of phenylpropanoids

Technical field

The present invention relates to pharmaceutical technology fields, more particularly, to a kind of preparation method of new phenylpropanoids.

Background technology

It is various, active notable that isolated constituent structure is extracted from natural drug, it is isolated and purified, structure Modification, transformation and it is fully synthetic, be always a main thought of new drug development.

TNF-α：Be it is a kind of can direct killing tumour cell and to cell factor of the normal cell without overt toxicity, be so far One of strongest bioactie agent of direct killing function of tumor found until the present, however its toxic side effect is also very tight Weight.

IL-1β：In local low concentration, collaboration stimulation APC and T cell activation, promote B cell proliferation and secretory antibody, into Row immunological regulation.There is endocrine effect when a large amount of generations：Induced liver acute phase protein synthesizes, and causes fever and cachexia.

IL-6：Mankind's IL-6 genes are located on No. 7 chromosome；IL-6 molecular weight is between 21~30KD.Mainly by list Core macrophage, Th2 cells, vascular endothelial cell, fibroblast generate.Activating B cell can be stimulated to be proliferated, secretion is anti- Body；Stimulate T cell proliferation and CTL activation；Cell cultured supernatant synthesized acute phase albumen participates in inflammatory reaction；Promote haemocyte hair It educates.

IL-6 can be synthesized by various kinds of cell, including the T cell of activation and B cell, monocytes/macrophages, endothelial cell, Epithelial cell and fibroblast etc..There are many target cell of IL-6 effects, including macrophage, liver cell, static T thin Born of the same parents, the B cell of activation and thick liquid cell etc.；Its biological effect is also sufficiently complex.

OH is most active reactive oxygen species in biosystem, can lead to DNA in cell and organism, protein and fat Matter oxidative damage.

Therefore, seek a kind of new preparation method, isolated new compound is extracted from natural plants, can inhibit thin Born of the same parents' inflammatory factor TNF-α, the expressional function of IL-1 β, IL-6 inhibit the activity of hydroxyl radical free radical (- OH), are applied to inflammatory disease The treatment of disease, is necessary.

Waras medicinal material is that pulse family (Leguminosae) Moghania (Flemingl.Roxb. or Moghania) plant is big The dry root of leaf waras (Moghaniamacrophylla (Willd.) O.Kuntze), the southeast is distributed mainly in China Area.The plant is in Chinese Plants will (1995,41:313), Flora of Taiwan (1977,3:258), Hainan flora (1965, 2:311)、《Chinese Higher plant illustrated handbook》(1972,2:510), Chinese main plant figure says (1955, pp707) and Guangzhou plant Will is included in (1956, pp361).Waras medicinal material is the genunie medicinal materials of Guangxi province, and history is loaded in《The Illustrated Book on Plants》, There is extensive civil medication basis.Its nature and flavor is sweet, micro-puckery, puts down, and has removing damp-heat and other effects, is mainly used for treating rheumatic bone Bitterly, the gynecological diseases such as more than traumatic injury, chronic nephritis, dysmenorrhoea and leukorrhea.The medicinal material has been recorded at present into version in 2005《Middle traditional Chinese medicines Allusion quotation》Annex.

The ingredient that Flemingia macrophylla has been reported mainly has flavonoids, steroid, terpene, Anthraquinones, volatile oil ingredient, has There is certain pharmacological activity.

Flemingia macrophylla pharmacological activity is various, reports the more neuroprotection that has, anti-inflammatory, antioxidation, to disease Anthelmintic action, parahormone effect, cytotoxicity, antibacterial action and immunological enhancement, the antifatigue effect of pathogenic microorganism.

Waras is now widely used for the Chinese patent drug production of the types such as gynaecology, arthralgia pain due to rheumatism, such as FUKE QIANJIN PIAN, gynaecology A thousand pieces of gold capsule, infusion of cherokee rose and spatholobus stem, JINJI JIAONANG etc., such Chinese patent drug is mainly used for gynaecological disease, and (dysmenorrhoea, cold uterus be infertile, uterus Sagging, pelvic infecton, mastitis, leukorrhea be more, the postpartum deficiency of blood, arthralgia, postpartum waist and knee, hypogalactia and newborn sore etc.), weak anaemia (woman anemia, deficient qi and blood and after being ill deficiency of vital energy etc.).In recent years, what clinical report was more is that FUKE QIANJIN PIAN is scorching in treatment gynaecology Effect in terms of disease.

Currently, in the document of waras, report that the document of phenylpropanoids is few, finds a kind of new preparation side Method isolates effective Phenylpropanoid Glycosides class noval chemical compound from natural plants, is isolated and purified to it, structural modification and synthesis, Developing new drug is applied to the treatment of diseases associated with inflammation, significant.
