Abstract

Osteoarthritis is a progressive, chronic joint disease characterized by pain, stiffness, and limited mobility, which can lead to physical disability in severe cases. Owing to its complex pathological features, effective treatments for osteoarthritis are lacking. Fangchinoline is a natural alkaloid found in the tuberous roots of plants belonging to the Menispermaceae family. Fangchinoline reportedly possesses anti-inflammatory, antioxidant, and anticancer properties; however, its role in osteoarthritis progression remains unclear. In this study, we investigated the protective effects and potential mechanisms of fangchinoline against osteoarthritis. In vitro, we confirmed that fangchinoline alleviates interleukin-1β-induced cartilage inflammation, reduces the levels of metabolic factors, such as inducible nitric oxide synthase and matrix metalloproteinase-3, and modulates the expression of aggrecan, which enhances extracellular matrix synthesis. In vivo, we demonstrated that fangchinoline can ameliorate articular cartilage degeneration and reduce inflammatory destruction in a destabilization of the medial meniscus mouse model. The nuclear factor kappa B (NF-κB) signaling pathway in osteoarthritis has been a primary target for drug development, and our results suggest that fangchinoline exerts anti-inflammatory effects by inhibiting the activity of IKKα/β. Using an in vitro human cartilage culture model, we further validated that fangchinoline significantly mitigates cartilage degeneration and inflammation by modulating the NF-κB signaling pathway. This evidence highlights its dual action in preserving cartilage integrity and suppressing inflammatory responses. These findings collectively underscore fangchinoline as a potent inhibitor of NF-κB, capable of attenuating key pathological processes associated with osteoarthritis. Therefore, fangchinoline emerges as a promising therapeutic candidate for slowing the progression of osteoarthritis.

期刊介绍: Toxicology and Applied Pharmacology publishes original scientific research of relevance to animals or humans pertaining to the action of chemicals, drugs, or chemically-defined natural products. Regular articles address mechanistic approaches to physiological, pharmacologic, biochemical, cellular, or molecular understanding of toxicologic/pathologic lesions and to methods used to describe these responses. Safety Science articles address outstanding state-of-the-art preclinical and human translational characterization of drug and chemical safety employing cutting-edge science. Highly significant Regulatory Safety Science articles will also be considered in this category. Papers concerned with alternatives to the use of experimental animals are encouraged. Short articles report on high impact studies of broad interest to readers of TAAP that would benefit from rapid publication. These articles should contain no more than a combined total of four figures and tables. Authors should include in their cover letter the justification for consideration of their manuscript as a short article.
