Abstract

The invention discloses an application of Longistyline A-2-carboxylic acid in osteoclast formation inhibiting and osteoporosis preventing medicines. The chemical structural formula of the LongistylineA-2-carboxylic acid is shown in the description. The invention also provides an application of the Longistyline A-2-carboxylic acid in medicines for inhibiting the osteoclast marker gene expression in the osteoclast formation process, an application of the Longistyline A-2-carboxylic acid in medicines for inhibiting the RANKL-induced NF-kappa and NFAT pathway activity through inhibiting the expression level of proteins in the upstream and downstream pathways in the osteoclast differentiation process, and an application of the Longistyline A-2-carboxylic acid in medicines for inhibiting RANKL-induced reactive oxygen species (ROS) and important calcium ion oscillation reactions in the osteoclast differentiation process. RANKL-induced osteoclast formation and the functions of osteoclast areinhibited to reduce the bone loss in OVX mice; and the Longistyline A-2-carboxylic acid can improve the bone mineral density of OP patients, which proves that the Longistyline A-2-carboxylic acid canbe a potential choice for treating osteoporosis and other osteolytic diseases.

Description

technical field [0001] The present invention relates to a kind of lignan and its application, in particular to the application of a kind of lignan in inhibiting the formation of osteoclasts and preventing osteoporosis. Background technique [0002] Bone is a dynamic tissue in the human body that maintains its structural stability through continuous bone remodeling and mineralization. Bone tissue includes osteoblasts, osteoclasts, and osteocytes. The bone formation ability of osteoblasts and the bone resorption function of osteoclasts play an important role in maintaining the balance of bone remodeling. The dysfunction of osteoclast bone resorption and osteoblast bone formation will lead to bone diseases such as osteoporosis. Osteoporosis is characterized by decreased bone density, microarchitectural destruction of bone tissue leading to decreased bone strength, increased bone fragility, and increased fracture risk. According to a report by the WHO, approximately 72% of wo...
