To investigate the effect of trifolirhizin on neonatal rat model of asthma, and the mechanism of action involved. Neonatal rats (n = 50) were randomly assigned to 5 groups (10 pups/group): sham, asthma and three treatment groups. With the exception of sham group, the rat pups were sensitized i.p. with ovalbumin (OVA) at a dose of 20μg/kg on days 7 and 21 postpartum. Rats in the treatment groups received trifolirhizin intragastrically at doses of 2, 4 and 5 mg/kg on day 7 postpartum. Eosinophils in bronchoalveolar lavage fluid (BALF) were counted using hematol. analyzer. Serum Ig (Ig)E and interleukin (IL)-4, IL-5 and IL-13 levels in BALF were determined using their resp. ELISA (ELISA) kits. MRNA (mRNA) expressions of mucin 5AC (Muc5AC), mucin 5B (Muc5B), tumor necrosis factor α (TNF-α) and intercellular adhesion mol.-1 (ICAM-1) were determined using immunohistochem. staining, while the protein expression of inhibitor of nuclear factor of kappa light polypeptide gene enhancer in B-cells alpha (IκBα) was assayed by Western blotting. Serum IgE level was significantly higher in asthma group than in sham group, but was significantly and dose-dependently reduced after treatment with trifolirhizin (p < 0.05). Lung tissue damage was also significantly mitigated in the treatment groups, relative to asthma group (p < 0.05). Trifolirhizin treatment significantly and dose-dependently downregulated the mRNA expressions of Muc5AC, Muc5B, TNF-α and ICAM-1, but upregulated IκBα protein expression significantly and dose-dependently (p < 0.05). Bronchoalveolar lavage fluid (BALF) levels of IL-4, IL-5 and IL-13 were significantly higher in asthma group, but were significantly and dose-dependently reduced after treatment with trifolirhizin (p < 0.05). Conclusion: These results indicate that trifolirhizin mitigates OVA-induced lung inflammation and tissue damage in neonatal rats via inhibition of NF-κB signaling pathway, thus affording a potential therapeutic strategy for the management of asthma. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 6807-83-6Quality Control of (2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol).

Benzofuran derivatives are one of the most important oxygen-containing heterocycles. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.Quality Control of (2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol
