ABD-295 is an antiresorptive agent, osteoclast inhibitor, and biphenylsulfide derivative. ABD-295 has potent inhibitory effects on osteoclastic bone resorption in vitro. ABD-295 prevents ovariectomy-induced bone loss in vivo.
Deoxypyridinoline is one of two pyridinium cross-links that provide structural stiffness to type I collagen found in bones. It is excreted unmetabolized in urine and is a specific marker of bone resorption and osteoclastic activity.
Osteoprotegerin is a soluble secreted member of the tumor necrosis factor receptor superfamily, inhibiting osteoclastogenesis by interrupting the signaling between stromal cells and osteoclastic progenitor cells, leading to excess accumulation of bone and cartilage.
Curculigoside B shows antioxidative and antiosteoporotic activities, it can decrease area of bone resorption pit, osteoclastic formation and TRAP activity.
Dalbergiphenol shows antiosteoporotic activity, dalbergiphenol treatment can effectively prevent OVX-induced increase in bone loss and decrease in bone strength possibly by increasing osteoblastic activities and by decreasing osteoclastic activities.
