3H, relative molecular mass are 499.69.TCDCA has characteristics such as medicament sources is extensive, safe, effective as a kind of main component in the bile.Present discover TCDCA have antiinflammatory (Li Peifeng, Cao Jinshan, Guan Hong etc. Chinese veterinarian's medical magazine, 2002,21 (1): 7-10), body fluid and cellular immunization regulate (Shi Youfei, Li Peifeng, Li Jinlian etc. the Chinese Pharmacological circular, 2007,23 (7): 859-864), anti-intestinal epithelial cell apoptosis (Turner DJ, Alaish SM, Zou T, et al.Ann Surg.2007,245 (3): 415-25) etc.
Osteoporosis (Osteoporsis OP) is the human endocrine Developmental and Metabolic Disorder, constantly reduces with bone ore deposit composition and bone matrix equal proportion, and the sclerotin attenuation, bone trabecula quantity reduces, and bone fragility increases to a kind of general skeletal diseases of feature.Clinical manifestation is a lumbago and backache, is easy to fracture.The patient of this disease is mainly most of postmenopausal women and old people, and the whole world has 200,000,000 people to suffer from osteoporosis approximately at present, and China has patients with osteoporosis more than 8,000 ten thousand now.Along with the process of social population's aging is constantly aggravated, the osteoporosis disease has become a serious social public health problem.The osteoporotic method of existing control generally is Drug therapy, bone peptide sheet, calcitonin or the alendronate etc. of mainly containing commonly used, and said medicine can promote osteogenesis; Also have to adopt and directly replenish calcium preparation,, have the drawback that price is higher or side effect is more of taking medicine for a long time, can not satisfy the osteoporotic requirement of control well though above-mentioned method has certain effect to fill up the part of bone-loss.
Summary of the invention
The inventor is through long-term research to Taurochenodeoxycholic Acid; the inventor is by discovering that to Taurochenodeoxycholic Acid it can promote osteoblast secretion Bone Gla protein; and can improve the bone density that has reduced; and then be applied to prevent and treat osteoporosis; directly administration also can be made into various dosage forms and be used to prevent or treat osteoporosis or other diseases or the state relevant with it.
The invention provides Taurochenodeoxycholic Acid in prevention or prevent and treat application on the osteoporosis; directly administration; can be principal agent also, cooperate other adjuvants to prepare the medicine of various dosage forms such as injection, tablet, powder, granule, capsule, oral agents with it.
The inventor finds by experiment, when directly by oral administration, can significantly promote osteoblast secretion Bone Gla protein, and Bone Gla protein is a kind of noncollagen protein of emiocytosis in the osteogenetic process, is Ca
2+Combine with hydroxyapatite, the essential composition of sclerotin mineralising.Cell with osteogenic activity can produce Bone Gla protein in the maturation period in later stage.Because the Bone Gla protein secretion level is the embodiment of Oesteoblast growth and function status, is osteoplastic sign.So, promoted the secretion of Bone Gla protein, illustrate and improved osteoblastic vigor, help the formation of bone.In addition; Taurochenodeoxycholic Acid can improve the bone density by the osteoporosis model of dexamethasone preparation; because this model has general representativeness, confirmed that Taurochenodeoxycholic Acid can improve the bone density that has reduced, and then confirmed that it is in the application that prevents and treats on the osteoporosis.
In addition; the inventor also finds; when in food or feedstuff, directly adding Taurochenodeoxycholic Acid; by normal feed digestion process; also can promote osteoblast secretion Bone Gla protein to improve bone density; therefore also can adopt the above-mentioned form of mixtures that contains Taurochenodeoxycholic Acid, prevent and treat osteoporosis such as forms such as health foods.
By above-mentioned research, the present invention is for prevention or prevent and treat osteoporosis, and a brand-brand-new way is provided, and then provides technical foundation for the exploitation of a series of control medicine for treating osteoporosis.Taurochenodeoxycholic Acid is as the effective ingredient of animal body, and its untoward reaction is little, as the medicine of replenishing the calcium, can prevent and treat the osteoporosis disease by life-time service.
