Application of signal pathway signal inhibitor or protein synthesis inhibitor or madecassic acid in preparation of drug for treating osteoporosis

Abstract

An application of a signal pathway signal inhibitor or a protein synthesis inhibitor or a madecassic acid in preparation of a drug for treating osteoporosis is disclosed. The madecassic acid inhibitsan expression of key protein-NFATc1 required for effect performance of osteoclasts through NF-[kappa]B, calcium / calmodulin-dependent kinase and MAPK three signal transduction pathways, and RANKL-induced osteoclast generation is ultimately inhibited. The application first describes and demonstrates that the madecassic acid has a satisfactory therapeutic effect on osteoporosis caused by estrogen deficiency, suggests that a natural compound madecassic acid extracted from Chinese herbal medicine has good application prospects in prevention and treatment of the osteoporosis, and provides a new option and a drug development idea for the treatment of the osteoporosis.

Description

technical field [0001] The invention relates to the technical field of osteoporosis drugs, in particular to the application of a signal pathway signal inhibitor or protein synthesis inhibitor or madecassoside in the preparation of drugs for treating osteoporosis. Background technique [0002] Osteoporosis is a systemic metabolic bone disease characterized by decreased bone mass, degeneration of bone tissue microstructure, and increased bone fragility. It is more common in postmenopausal women and elderly men. At present, my country has more than 210 million people over the age of 60 (about 15.5% of the total population), and nearly 140 million people over the age of 65 (about 10.1% of the total population). It is the country with the largest absolute number of elderly people in the world. According to With the forecast of population structure and the extension of life expectancy, the number of elderly people will further increase in the future. As a bone disease related to a...

Problems solved by technology

However, bisphosphonates have relatively large gastrointestinal side effects and nephrotoxicity, which are difficult for elderly patients to tolerate; long-term use of calcitonin can increase the risk of potential cancer; estrogen is mainly used for postmenopausal women with osteoporosis , but its side effects are relatively large, which will increase the risk of endometrial cancer, breast cancer and cardiovascular disease in women
