Antinociceptive,antipyretic, and anti-inflammatory activities of <Emphasis Type="Italic">Putranjiva roxburghii</Emphasis> Wall. leaf extract in experimental animals

The effects of the ether extract from the leaves of Putranjiva roxburghii (P. roxburghii) Wall. were assessed on nociceptive responses in mice by using writhing, hot plate, and formalin tests and the antipyretic activity was determined in yeast-induced fever in rats. Anti-inflammatory activities were also investigated using carrageenin-induced paw edema in rats and croton oil-induced ear and anus edemas. The ether extract (100, 200, and 400 mg/kg, p.o.) of P. roxburghii dose-dependently produced analgesic activity in acetic acid-induced writhing in mice. The extract had no significant effect in the hot plate test in mice. At the dose of 400 mg/kg, the extract significantly suppressed the licking activity in the late phase of the formalin test in mice and decreased fever induced by yeast in rats. The extract exhibited moderate inhibitory activity of inflammation in carrageenin-induced paw edema in rats. The extract inhibited croton oil-induced ear edema in a dose-dependent manner (1.25, 2.5, and 5.0 mg/ear) in mice. The extract decreased anus edema induced by croton oil at the high dose of 800 mg/kg in rats. The results indicated that the ether extract of P. roxburghii leaves possesses analgesic, antipyretic, and anti-inflammatory activities.

Analgesic and anti-inflammatory activities evaluation of (-)-O-acetyl, (-)-O-methyl, (-)-O-dimethylethylamine cubebin and their preparation from (-)-cubebin

The anti-inflammatory and antinociceptive effects of the acetylated (2), methylated (3) and aminated (4) derivatives of cubebin (1), obtained by its reaction with acetic anhydride, methyl iodide and dimethylethylamine chloride, respectively, were investigated, using different animal models. The compound (2) was the most effective anti-inflammatory one in the carrageenin-induced paw edema in rats and was the only one which showed dose-response correlation for this assay with r = 0.993 and Y = 64.58x + 0.22. Besides, compounds (2) and (4) were more effective than cubebin in inhibiting acetic acid-induced writhing in mice, producing dose-response correlation with doses of 10, 20 and 30 mg/kg, respectively. Regarding the hot plate and the cell migration tests in rats, none of the four tested compounds showed activity. Overall, the results showed that the acetylation and amination of cubebin were efficient in enhancing its analgesic activity, as well as its anti-inflammatory activity.     

Isofraxidin exhibited anti-inflammatory effects in vivo and inhibited TNF-α production in LPS-induced mouse peritoneal macrophages in vitro via the MAPK pathway

Isofraxidin (IF) is a Coumarin compound that can be isolated from medicinal plants, such as Sarcandra glabra (Thunb.). Nakai is widely used in Asian countries for the treatment of anti-bacterial, anti-inflammatory and anti-tumour action. The present investigation was designed to evaluate the effect of IF on inflammation and nociception. In addition, we investigated a potential novel mechanism to explain the anti-inflammatory properties of IF. In vivo, xylene-induced mouse ear edema, carrageenan-induced rat paw edema, LPS-induced mouse endotoxic shock, acetic acid-induced mice writhing and formalin-induced mouse pain models were used to evaluate the anti-inflammatory activity of IF. In vitro, we examined the effects of IF inhibition on TNF-α production and the regulation of ERK1/2 and p38 phosphorylation activity in LPS-induced mouse peritoneal macrophages. Our results demonstrated that IF can significantly decrease xylene-induced ear edema, carrageenan-induced paw edema, acetic acid-induced writhing and formalin-induced pain. Moreover, IF greatly inhibited the production of TNF-α in the serum of LPS-stimulated mice and peritoneal macrophages, and it decreased phospho-p38 and ERK1/2 protein expression in LPS-stimulated mouse peritoneal macrophages. Overall, our data suggest that IF possesses significant analgesic and anti-inflammatory activities that may be mediated through the regulation of pro-inflammatory cytokines, TNF-α and the phosphorylation of p38 and ERK1/2.
