| Abstract: | Two new compounds, euphorbinoside (1) and dehydropicrorhiza acid methyl diester (2), along with 24 known compounds (3–26) were isolated from Euphorbia humifusa Willd. The effects of these compounds on soluble epoxide hydrolase (sEH) inhibitory activity were evaluated. Flavonoid compounds (10–21) exhibited high sEH inhibitory activity. Among them, compounds 12, 13, and 19 greatly inhibited sEH enzymatic activity, with IC50 values as low as 18.05 ± 1.17, 18.64 ± 1.83, and 17.23 ± 0.84 μM, respectively. In addition, the effects of these compounds on lipopolysaccharide (LPS)-induced nitric oxide (NO) and tumor necrosis factor alpha (TNF-α) production by RAW 264.7 cells were investigated. Compounds 3–6, 8, 18, 20–23, and 25–26 inhibited the production of both NO and TNF-α, with IC50 values ranging from 11.1 ± 0.9 to 45.3 ± 1.6 μM and 14.4 ± 0.5 to 44.5 ± 1.2 μM, respectively. |
