Definitions
- the invention relates to a new use of several chemical components in the traditional Chinese medicinal material Cynomorium, in particular, a new use of flavonoids and terpenoids in Cynomorium as phytoestrogens. Background technique
- Cynomorium Lock P (Herba Cynomorii) is a dry fleshy stem of the Cynomorium «g»Wc « «Rupr. Cynomorium is sweet and warm, and it is a very rare natural rare plant. It has the functions of tonifying kidney yang, benefiting essence and blood, and relaxing the intestines. It is effective in treating impotence, nocturnal emission, weak waist, constipation, blood stasis, hematuria, and neurasthenia. Studies on the chemical constituents of Cynomorium indicate that Cynomorium contains flavonoids, triterpenoids, sugars and glycosides, tannins, body types, volatile constituents, organic acids, amino acids, inorganic elements and ions. The flavonoids include (+)-catechin, (-)-catechin, citrusin 4,-0-glucopyranoside, and citrus aglycones.
- Estrogen is a key regulatory hormone in women. It is mainly produced by the ovary and placenta. Estrogen is classified as a steroid hormone according to its chemical structure. It is fat-soluble and has many target tissues, including reproductive system, bone and cardiovascular. Estrogen is mainly divided into two categories: steroidal estrogens and non-organic estrogens. Body estrogen is an endogenous component of the ovary secretion of mammals. There are currently three types of steroidal estrogens found in humans: estradiol, estriol and estrone isolated from pregnant women's urine. It is mainly composed of estradiol and has the strongest activity. Steroidal estrogen plays an important role in life-sustaining, regulatory functions, body development, immune regulation, dermatological treatment and fertility.
- Non-steroidal estrogens are mainly stilbene glycosides. It is generally believed that estrogen binds to the corresponding estrogen receptor (ER) in the cell, thereby triggering a series of downstream events such as initiation of transcription, resulting in physiological effects.
- the affinity of non-steroidal estrogens to the estrogen receptor is 1/100 or 1/1000 of estradiol. Because clinical long-term use of estrogen can cause shortcomings such as breast cancer, endometriosis and carcinogenesis, people are seeking alternatives to estrogen.
- Phytoestrogen (PE) is a class of non-steroidal compounds widely found in plants that bind to ER in the body.
- phytoestrogens have a good preventive and therapeutic effect in preventing tumors, treating cardiovascular diseases and osteoporosis, improving menopausal symptoms, protecting the nervous system, and not finding such defects. influences. Therefore, phytoestrogens are often studied as natural estrogen substitutes. Although the ability of PE to bind to estrogen receptors is only 1/500-1/1000 of estrogen, its side effects in hormone replacement therapy (HRT) are small, so researchers have a great interest in this and hope that PE is in HRT. Play a potential medical value.
- HRT hormone replacement therapy
- Estrogen has a wide range of physiological functions in the growth, development, cell differentiation and reproductive system of the body. Estrogen exerts various biological effects mainly through ER.
- ER has two subtypes, ERoc and ERP, which are expressed differently in many tissues and cells of the human body. The expression levels of the two subtypes are different in the same tissue cells. The expression levels of the same subtypes in different tissue cells are also different, so the interaction of any ligand with Ero and ERP is intricate. The tissue distribution of ERa and ERP is different.
- the expression of ERO is mainly in the uterus, mammary gland, fallopian tube and vaginal epithelium.
- the expression of ERP is weak, while the ovary is dominant in the expression of ERP. Most of it is present in granulosa cells, and vascular smooth muscle cells are expressed. ⁇ Main.
- the object of the present invention is to find phytoestrogens with estrogenic activity and/or no estrogenic side effects, providing a new therapeutic option for the clinic.
- the present inventors have surprisingly discovered that some chemical components such as flavonoids and terpenoids extracted from the traditional Chinese medicine Cynomorium It has exact estrogenic activity and can be used as a phytoestrogens for the replacement of estrogen.
- the present invention has been completed based on the above findings.
- a first aspect of the invention provides the use of Cynomorium for the manufacture of a medicament for the treatment and/or prevention of a disease associated with insufficient secretion of estrogen from a mammal (e. g., human).
- a second aspect of the present invention provides a Cynomorium extract comprising at least one component selected from the group consisting of: chrysophanol, emodin, catechin, (-) epicatechin gallate, citrus _4 '-0-glucopyrein, phlorizin.
- a third aspect of the invention provides one or more active ingredients selected from the group consisting of: chrysophanol, emodin, catechin, (-) epicatechin-3-0-gallate , citrus _4'-0-glucoside, phlorizin.
- a fourth aspect of the invention provides the use of a Cynomorium extract for the manufacture of a medicament for the treatment and/or prevention of a disease associated with insufficient secretion of estrogen in a mammal (e.g., human).
- a mammal e.g., human
- a fifth aspect of the invention provides the use of a combination of one or more selected from the group consisting of: in the manufacture of a medicament for the treatment and/or prevention of a disease associated with insufficient secretion of estrogen in a mammal (e.g., human): rhubarb Phenol, emodin, catechin, (-) epicatechin-3-gallate, citrus-4'-0-glucoside, phlorizin.
- a sixth aspect of the invention provides the use of Cynomorium in the preparation of a medicament for phytoestrogens.
- a seventh aspect of the invention provides the use of a Cynomorium extract for the preparation of a medicament for use as a phytoestrogens.
- An eighth aspect of the invention provides the use of a combination of one or more selected from the group consisting of: chrysophanol, emodin, catechin, (-) epicatechin-3 -0-gallate, citrus-4'-0-glucoside, phlorizin.
- a ninth aspect of the present invention provides a pharmaceutical composition for treating and/or preventing a disease associated with insufficient secretion of estrogen in a mammal (e.g., human), comprising a therapeutically and/or prophylactically effective amount of Cynomorium extract And optionally a pharmaceutically acceptable excipient.
- a tenth aspect of the invention provides a pharmaceutical composition for treating and/or preventing a disease associated with insufficient secretion of estrogen in a mammal (e.g., human), comprising a therapeutically and/or prophylactically effective amount of at least one drug Active ingredient and optionally pharmaceutically acceptable
- the pharmaceutically active ingredient is selected from the group consisting of: chrysophanol, emodin, catechin, (-) epicatechin-3-0-gallate, citrus-4'--glucoside, root Derinoside.
