Background: Verbascoside, a compound classified as a phenylethanol glycoside in Dihuang, has been the subject of modern pharmacological investigations. These studies have revealed its noteworthy antioxidant, anti-inflammatory, memory-enhancing, neuroprotective, antitumor, and various other pharmacological properties. While verbascoside exhibits favorable antioxidant effects, its precise mechanism of action in ameliorating osteoporosis through the treatment of oxidative stress remains unclear.

Methods: This study employed CCK8, ALP, ELISA, and ROS staining techniques to examine the osteoporotic effects of verbascoside on zebrafish and MC3T3-E1 cells. Additionally, this study aimed to investigate the molecular mechanism by which verbascoside improves osteoporosis by mitigating oxidative stress. To identify the common targets of verbascoside in relation to oxidative stress and osteoporosis, network pharmacology and molecular dynamics simulation were employed. The construction of the verbascoside - oxidative stress - osteoporosis - potential target gene network aimed to identify the core targets, while the mechanism of action was elucidated through KEGG analysis, and the accuracy was confirmed by assessing the mRNA expression of the targets.

Results: In vivo experiments demonstrated that verbascoside exhibited therapeutic effects on osteoporosis and reduced ROS production in zebrafish. In vitro experiments further revealed that verbascoside enhanced the proliferation and differentiation of MC3T3-E1 cells, thereby improving the oxidative stress status of osteoblasts. Thirteen core targets and estrogen signaling pathways were identified through the application of network pharmacology. The pivotal role of the estrogen signaling pathway in facilitating the ability of verbascoside to mitigate oxidative stressinduced osteoporosis was substantiated by the modulation of target protein mRNA expression.

Conclusion: The findings underscore the considerable therapeutic potential of verbascoside in ameliorating osteoporosis through the alleviation of oxidative stress, thus establishing it as a promising compound for the treatment of this condition.
