摘要：
C@MSN-P-A8, a bone-targeted nano-sustained-release system, shows promise in treating postmenopausal osteoporosis by effectively inhibiting osteoclastogenesis and enhancing bone density. The study highlights its mechanism of action involving the suppression of NF-κB and MAPK pathways, demonstrating significant therapeutic potential. In vivo experiments in ovariectomized rats reveal improved bone microarchitecture and density, positioning C@MSN-P-A8 as a viable candidate for innovative osteoporosis therapies.
