ETHNOPHARMACOLOGICAL RELEVANCE: Wuwei Ganlu is a Tibetan medicated-bath formula, and traditionally applied for limb stiffness, "yellow-water" effusion, and joint swelling. However, its efficacy against exercise-induced fatigue and mechanisms remain unclear.
AIM OF THE STUDY: This study evaluated the anti-fatigue activity of WGL and explored mitochondrial and redox-inflammatory mechanisms.
MATERIALS AND METHODS: UPLC-Q-Orbitrap-MS/MS was used to analyze the constituents of WGL. Network pharmacology prioritized mitochondrial and inflammatory hubs. Docking tested ligand-target feasibility. Kunming mice underwent 14 days of weight-loaded forced swim with daily warm WGL baths.
RESULTS: UPLC-Q-Orbitrap-MS/MS profiled WGL and tentatively identified 33 constituents spanning flavonoids (e.g., quercetin, luteolin, kaempferol, myricetin, afzelin), phenolic acids (e.g., 4-hydroxybenzoic acid and prenylated derivatives), and terpenoids. Network pharmacology analysis that integrated compound-target links with fatigue related genes prioritized hubs involved in mitochondrial energetics, inflammatory control (e.g., AKT1, PIK3CA, TGFB1) and the PI3K-AKT, oxidative phosphorylation pathways. Docking indicated that several flavonoids, such as quercetin and luteolin, showed adopted plausible high affinity poses with these targets. Subsequently, a 14-day weight-loaded forced-swim paradigm showed that WGL (2 g/L) increased endurance, lowered serum levels of blood urea nitrogen, creatine kinase and lactate dehydrogenase, reduced content of muscle malondialdehyde, and the mRNA expression of interleukin-1β and tumor necrosis factor-α, and improved gastrocnemius histopathology without affecting body weight. Untargeted serum metabolomics separated model from normal groups, and revealed a treatment-driven shift toward normal. Forced swimming suppressed ubiquinone-biosynthetic head-group intermediates, such as 4-Hydroxy-3-polyprenylbenzoate, 3,4-Dihydroxy-5-polyprenylbenzoate, and 2-polyprenyl-6-methoxyphenol, while WGL restored these signatures and elevated muscular mRNA expression of Coq7.
CONCLUSION: WGL counters exercise-induced fatigue by reinforcing CoQ-linked mitochondrial function and rebalancing redox-inflammatory signaling, which provides mechanistic support for its traditional external use and a rationale for further development.
