The Inhibitory Activity of Picria fel-terrae Lour Herbs Extract on Nitric Oxide Production toward RAW 264.7 Cells Induced by Lipopolysaccharide

AIM: The objective of this study was to evaluate the inhibitory activity of Picria fel-terrae Lour on Nitric Oxide production toward RAW 264.7 cells. METHODS: The extraction was obtained by maceration method using n-hexane, ethyl acetate and ethanol solvents and then nitric oxide (NO) production was obtained using Griess reagent. RESULTS: Extract of Picria fel-terrae Lour herbs can reduce the NO production toward RAW 264.7 cells with induced by lipopolysaccharide has obtained nitric concentrations 12.5 and 25 μg/mL from n-hexane extract (72.50 ± 4.51 and 10.42 ± 1.82), ethyl acetate extract: (88.33 ± 6.51 and 30.83 ± 6.86), ethanol extract: (75.00 ± 1.91 and 22.08 ± 2.53). CONCLUSION: n-hexane extract of Picria fel-terrae Lour Herbs has a high potential to reduce the NO production in LPS-stimulated RAW 264.7 cells compared to ethyl acetate and ethanol extracts of Picria fel-terrae Lour Herbs.

Eight new diarylheptanoids, a 1.2:1 mixture of (3S)- and (3 R)-1-(4-hydroxyphenyl)-7-phenyl-(4 E,6 E)-4,6-heptadien-3-ol (1a and 1b), a racemic mixture of (3S)- and (3 R)-1-(4-hydroxyphenyl)-3-methoxy-7-phenyl-(4 E,6 E)-4,6-heptadiene (2a and 2b), a ca. 1:1 mixture of (3S)- and (3 R)-1-(4-hydroxy-3-methoxyphenyl)-3-methoxy-7-phenyl)-(4 E,6 E)-4,6-heptadiene (3a and 3b), 3-acetoxy-1-(3,4-dihydroxyphenyl)-7-phenylheptan-5-ol (4), (3 R)-1-(4,5-dihydroxyphenyl)-7-phenyl-(6 E)-6-hepten-3,2′-epoxide (5), and thirteen known diarylheptanoids, 6-12, a 3:1 mixture of 13a and 13b, and 14-17, were isolated from the rhizomes of Curcuma comosa from Sakon Nakhon, northeastern part of Thailand. The isolated compounds were evaluated for their antiinflammatory activities on the inhibition of lipopolysaccharide-induced nitric oxide production in macrophage RAW 264.7 cells and the diarylheptanoids 1a and 1b mixture and 14 exhibited potent inhibitory activity.

Study of the chemical constituents of the stems of Derris trifoliata Lour. (Leguminosae) collected in Singapore led to the isolation and identification of three known and two new rotenoid derivatives. The new derivatives, named derrisfolin A (1) and B (2), inhibited nitric oxide production in murine macrophage-like RAW 264.7 cells stimulated with interferon-γ and lipopolysaccharide.

Potent Inhibition

Inhibition of nitric oxide production in lipopolysaccharide-activated RAW 264.7 macrophages by Jeju plant extractsNitric oxide (NO) produced in large amounts by inducible nitric oxide synthase (iNOS) is known to be responsible for the vasodilation and hypotension observed during septic shock and inflammation. Thus, inhibitors of iNOS may be useful candidates for the treatment of inflammatory diseases accompanied by the overproduction of NO. In this study, we prepared alcoholic extracts of Jeju plants and screened them for their inhibitory activity against NO production in lipopolysaccharide (LPS)-activated macrophages. Among the 260 kinds of plant extract tested, 122 extracts showed potent inhibitory activity towards NO production by more than 25% at a concentration of 100 μg/mL. Plants such asMalus sieboldii, Vaccinium oldhamii, Corylus hallaisanensis, Carpinus laxiflora, Styrax obassia, andSecurinega suffruticosashowed the most potent inhibition (above 70%) at a concentration of 100 μg/mL. The cytotoxic effects of the plant extracts were determined by colorimetric MTT assays and most plant extracts exhibited only moderate cytotoxicity at 100 μg/mL. Therefore, these plants should be considered promising candidates for the further purification of bioactive compounds and would be useful for the treatment of inflammatory diseases accompanying overproduction of NO.
