ETHNOPHARMACOLOGICAL RELEVANCE: Allergic asthma is one of the leading respiratory diseases with complex pathology. Sanfu Patch (SFP) is a traditional Chinese medicine preparation served as a potential topical application therapy for asthma in summer dog days. However, the potential pharmacological substances and underlying mechanism of SFP are not clear.
AIM OF STUDY: This study aimed to explore active ingredients in SFP as well as their presence in blood and lung tissues, investigate efficacy and potential molecular mechanism of SFP in relieving airway inflammation and intervening airway remodeling of asthma.
MATERIALS AND METHODS: The chemical components of SFP were analyzed by UPLC-QTOF-MS. Sinapine thiocyanate, protopine, allocryptopine, tetrahydrocoptisine and kansuiphorin C in SFP extract were quantified by UPLC-MS/MS. A mouse asthma model was established by ovalbumin (OVA). The lung histopathology, respiratory function, cytokine (IL-4, IL-5 and IL-13) and IgE levels were used to evaluate the therapeutic effect of SFP on asthmatic mice. Tandem mass tag (TMT)-based quantitative proteomics were performed on lung tissues to excavate proteins regulated by SFP. Western blot was used to validate the expression of relevant proteins. Finally, molecular docking was used to verify the targeting between screened proteins and constituents of SFP.
RESULTS: Sixty-three compounds were identified in SFP extract, along with twenty-five prototype components in blood and twenty in lung tissue have been found. The contents of sinapine thiocyanate, protopine, allocryptopine, tetrahydrocoptisine, and kansuiphorin C were quantified in SFP extract at 2.27 ± 0.06 mg/g, 1.36 ± 0.02 mg/g, 0.96 ± 0.02 mg/g, 0.42 ± 0.01 mg/g, 0.15 ± 0.01 mg/g, respectively. SFP had a significant ameliorative effect for allergic asthma in mice. SFP was contributed to alleviative airway hyperresponsiveness by declining airway resistance and increasing dynamic lung compliance. SFP not only attenuated airway inflammation and airway collagen deposition but also reduced serum and lung levels of IL-4, IL-5, IL-13, IgE, and significantly decreased the number of eosinophils in bronchoalveolar lavage fluid. The TMT-based quantitative proteomics showed that SFP improved autophagy and asthma pathways. SFP significantly reduced OVA-induced protein expressions of CD40, CD40L, and CLN5. Furthermore, molecular docking results indicated high bond energies of alkaloids, sinapine thiocyanate, and kansuiphorin C binding to CD40, CD40L, and CLN5.
CONCLUSIONS: It was demonstrated that SFP was a potential natural active preparation in the treatment of asthma, which may have an inhibitory effect on airway inflammation. The therapeutic effect of SFP was related to the lysosome pathway and asthma pathway.
