LHQW and quercetin reverses LPS-induced a reduction in cell viability. A The IC₅₀ in response to LPS using MTT assay was 28.86 μg/ml. B The EC₅₀ in response to LHQW using MTT assay was 10.09 μg/ml. C The EC₅₀ in response to quercetin using MTT assay was 5.65 μmol/L. D–F Cell Viability of 16HBE cells was assessed after 48 h of treatment with different concentrations of LPS, LHQW, and quercetin, n = 5 per group. G–I A colony formation assay was conducted with cells treated with different concentrations of LPS, LHQW, and quercetin. A representative of three experiments is shown, n = 3 per group. All data are presented as mean ± standard deviation, **p < 0.01, ***p < 0.001
