The aim of this study is to explore anti-inflammatory phytochemicals from B. chinensis based on the inhibition of pro-inflammatory enzyme, human neutrophil elastase (HNE) and anti-inflammatory activities in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage. Three stereoisomers of iridal-type triterpenoids (1–3) were isolated from the roots of B. chinensis and their stereochemistries were completely identified by NOESY spectra. These compounds were confirmed as reversible noncompetitive inhibitors against HNE with IC50 values of 6.8–27.0 µM. The binding affinity experiment proved that iridal-type triterpenoids had only a single binding site to the HNE enzyme. Among them, isoiridogermanal (1) and iridobelamal A (2) displayed significant anti-inflammatory effects by suppressing the expressions of pro-inflammatory cytokines, such as iNOS, IL-1β, and TNF-α through the NF-κB pathway in LPS-stimulated RAW264.7 cells. This is the first report that iridal-type triterpenoids are considered responsible phytochemicals for anti-inflammatory effects of B. chinensis.

The immunohistochemical results obtained with antibodies directed against human neutrophil elastase is described. It was found that neutrophil elastase can be used as a specific marker of cells of the neutrophilic lineage. In normal hematopoietic cell preparations, only promyelocytes and more differentiated myeloid cells stain positive for elastase. In acute or chronic myeloid and myelomonocytic leukemia, the same neutrophil myeloid cells stain positive, whereas neoplastic cells of the monocytoid line are negative. Using elastase in conjunction with other markers, it is possible to differentiate easily the involvement of different cell lines in myeloproliferative diseases.
