Fig. 5. Molecular docking binding model of human neutrophil elastase (HNE) with 1, its stereoisomer, related derivative and elastase inhibitors, (A) 1R; (B) 1S; (C) rhoipteleanin H; (D) HNE inhibitor GW475151 and (E) HNE inhibitor sivelestat. (Left panel) The ligand (sticks) is positioned according to the best binding interaction with HNE. Green dash lines are representing the hydrogen bonds between ligands and corresponding amino acids of the HNE active site. (Right panel) The main residues contributing to the binding are indicated by the respective amino acids three-letter abbreviations and number. Residues and dash lines in green, classical hydrogen bonding; yellow, carbon-hydrogen bonding; purple, hydrophobic bonding. Blue cloud represents solvent accessibility.

Fig. 4 in Anti-inflammatory, hepatoprotective and antioxidant activity of ellagitannin isolated from Melaleuca styphelioides

Fig. 4. Styphelioidin (1) inhibits the enzymatic activity of human neutrophil elastase in the cell-free system. Human neutrophil elastase (HNE) was incubated with 1 or DMSO (control) for 15 min. Elastase activity was measured spectrophotometrically at 405 nm. Data are expressed as mean ± SEM (n = 3). ***p <0.001 compared with the control (HNE only).

Fig. 3. The effects of 1 on degranulation and viability in human neutrophils. (A) 1 inhibits elastase release in fMLF/CB-induced human neutrophils. Human neutrophils were incubated with 1 or DMSO (control) 5 min and stimulated by fMLF in the presence of CB for another 10 min. Elastase release was measured spectrophotometrically at 405 nm. Data are expressed as mean ± SEM (n = 3). *p <0.05; **p <0.01 compared with the control (fMLF/CB only). (B) Human neutrophils were incubated with DMSO or 1 for 15 min. LDH release was expressed as the percentage of enzyme released by treatment compared with control (DMSO). The analysis was performed by using enzyme-associated immunosorbent assay and read at 490 nm. All data are shown as mean ± SEM (n = 3).
