Objective: Dietary curcumin and capsaicin are well known for their health beneficial potencies. The current study was done to assess the anti-inflammatory activity of curcumin, capsaicin and their combination by employing in vitro and in vivo models.Methods: We investigated the protective effect of curcumin, capsaicin and their combination using in vitro heat induced human red blood cell (HRBC) membrane stabilisation, in vivo 3% agar induced leukocyte mobilisation and acetic acid induced vascular permeability assay.Results: Curcumin, capsaicin and their combination exhibited concentration dependent protective effect against heat-induced HRBC membrane destabilisation, while combined curcumin and capsaicin restored 87.0±0.64 % membrane stability and it is found to be better than curcumin, capsaicin and diclofenac sodium (75.0±0.25. 72±0.9 and 80.0±0.31 %) protective effect. In agar suspension induced leukocyte mobilization assay, the combined curcumin and capsaicin had shown 39.5±1.58 % of inhibition compared to individual curcumin and capsaicin, which showed moderate inhibition of 16.0±3.14 and 21.6±2.17 % respectively. Besides, the combined curcumin and capsaicin had shown highly significant inhibition of acetic acid-induced vascular permeability in rats (62.0±3.14 %), whereas individual curcumin and capsaicin showed moderate inhibition of vascular permeability with 36.0±2.41 and 43.0±1.92 % respectively.Conclusion: This study demonstrates the significant anti-inflammatory property of combined curcumin and capsaicin at half of the individual concentration of curcumin and capsaicin.

: In vivo and in vitro studies reveal that ursolic acid (UA) is able to counteract endogenous and exogenous inflammatory stimuli, and has favorable anti-inflammatory effects. The anti-inflammatory mechanisms mainly include decreasing the release of histamine in mast cells, suppressing the activities of lipoxygenase, cyclooxygenase and phospholipase, and reducing the production of nitric oxide and reactive oxygen species, blocking the activation of signal pathway, down-regulating the expression of inflammatory factors, and inhibiting the activities of elastase and complement. These mechanisms can open up new avenues for the scientific community to develop or improve novel therapeutic approaches to tackle inflammatory diseases such as arthritis, atherosclerosis, neuroinflammation, liver diseases, kidney diseases, diabetes, dermatitis, bowel diseases, cancer. The anti-inflammatory activity, the anti-inflammatory mechanism of ursolic acid and its therapeutic applications are reviewed in this paper.

Lipospheres represent a novel type of fat-based encapsulation system produced for the topical drug delivery of bioactive compounds. The goal of this research work was to develop lipospheres, including ketoprofen applied for topical skin drug delivery. Ketoprofen lipospheres were formulated by melt emulsification method using stearic acid and Phospholipon® 90G. The lipospheres were analysed in terms of particle size and morphology, entrapment efficiency, Differential scanning calorimetry, In-vitro drug release, In-vivo (Anti-inflammatory activity). Outcomes of research revealed that particle size was found to be 9.66 µm and entrapment efficiency 86.21 ± 5.79 %. In-vivo, the study of ketoprofen loaded lipospheres formulation shows a higher plain formulation concentration in plasma (5.61 mg/mL). For dermis, ketoprofen retention was 27.02 ± 5.4 mg/mL for the lipospheres formulation, in contrast to that of the plain formulation group (10.05 ± 2.8 mg/mL). The anti-inflammatory effect of liposphere drug delivery systems was assessed by the xylene induced ear oedema technique and compared with marketed products. Finally, it seems that the liposphere drug delivery system possesses superior anti-inflammatory activity as compared to the marketed product gel consistencies. Liposphere may be capable of entrapping the medicament at very high levels and controlling its release over an extended period. Liposphere furnishes a proper size for topical delivery as well as is based on non-irritating and non-toxic lipids; it’s a better option for application on damaged or inflamed skin.

Abstract The genus Galphimia is widely distributed in Mexico, and is represented by 22 species, including medicinal species. The sedative and anti-inflammatory effects of galphimines produced by the species Galphimia glauca have been documented. Formerly, molecular studies using DNA barcodes demonstrated that nine populations botanically classified as Galphimia glauca belong to four different species of the genus Galphimia, and that only one exhibited the sedative properties; however, all the collected species showed anti-inflammatory activity. Other bioactive compounds like quercetin, galphins, galphimidins and glaucacetalins have been identified from methanolic extracts of plants botanically classified as Galphimia glauca. The aim of this work was to determine the anti-inflammatory activity of methanolic extracts of nine collected Galphimia spp. populations grown in Mexico. The possible modes of action were analyzed by evaluating the inhibition of LPS-induced inflammation processes both in vitro and in vivo. The nine populations were evaluated by an in vitro model using RAW 264.7 murine macrophage cells, and two populations (a galphimine-producing and a non-galphimine-producing population) were selected for the in vivo experiments of systemic inflammation and neuroinflammation in mice. Results suggest that an anti-inflammatory in vitro effect was present in all the studied populations, evidenced by the inhibition of nitrite production. An inhibitory systemic inflammation in mice was exerted by the two analyzed populations. In the neuroinflammation model, the anti-inflammatory effect was demonstrated in methanolic extract of the non-galphimine-producing population. For the populations of Galphimia spp. studied herein, the anti-inflammatory effect could not be correlated to the presence of galphimines.
