Background: Royal jelly (RJ) is one of the most effectual and beneficial remedies for human beings and currently utilized in many sectors, ranging from the pharmaceutical and food industries to cosmetic and manufacturing sectors due to RJ possessing many bio-therapeutical activities including anti-tumor, antimicrobial and antioxidant activities, vasodilative and hypotensive activities, as well as growth-stimulating, infection-preventing, anti-hypercholesterolemic and anti-inflammatory activities. However, some reports showing direct consumption of RJ can lead to severe allergic reaction and has been linked with acute asthma, dermatitis, and life-threatening anaphylaxis. Thus, this research purposes to explore the potential anti-inflammatory and anti-allergic activities of hydrolyzed RJ as a function of enzyme and the extent of hydrolysis.Methods: RJ was enzymatically hydrolyzed with three commercial enzymes (AlcalaseÒ, FlavourzymeÒ and ProtamexÒ). Anti-inflammatory activity of the hydrolysates was measured by their inhibitory effect on nitric oxide (NO) production of lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. Anti-allergy was determined from the ability of the hydrolysates to inhibit b-hexsosaminidase (b-HEX) release from RBL-2H3 mast cells. Cytotoxicity was also investigated in both RAW264.7 macrophage cells and RBL-2H3 mast cells.Results: The electrophoretic profiles indicated that AlcalaseÒ and FlavourzymeÒ hydrolysates did not show the presence of proteins causing allergic reaction after 60 mins of hydrolysis while these allergens disappeared from ProtamexÒ hydrolysate at the hydrolysis time of 240 min. It was observed that hydrolyzed RJ showed no toxicity on RAW264.7 and RBL-2H3 cells. With the progression of hydrolysis, IC50 values of NO production inhibition significantly decreased while degree of hydrolysis (DH) was increased in all hydrolyzed samples (p < 0.05). Results of b-HEX release inhibition were found in the same fashion. FlavourzymeÒ hydrolysate at the 240 min time point effectively mitigated the oxidative stress and protected DNA in a dose dependent manner.Conclusions: RJ hydrolysates from FlavourzymeÒ resulted in peptides with anti-inflammatory activity as determined by the inhibition of NO production in LPS-stimulated RAW264.7 macrophage cells and anti-allergic property as measured by the suppression of degranulation of sensitized RBL-2H3 cells. Anti-inflammatory effect may be due to their anti-oxidative capability. Inhibition of b-HEX release may be due to their membrane-stabilizing effects or/and blockade of IgE antibody binding to its receptors.Keywords: anti-inflammation, enzymatic hydrolysate, royal jelly, anti-allergy

Abstract Flavonolignans, for example, silymarin and silybin, have interesting biological activities. For the first time, three new flavonolignans named oenanthenoid A-C (1–3) and nine known flavonolignan derivatives (4–12) were isolated from Oenanthe javanica. Comprehensive spectroscopic data analysis and references were used to identify all of the compounds. The anti inflammatory activities of these isolates (1–12) on RAW264.7 macrophage cells were investigated. Three new compounds (1–3) demonstrated anti inflammatory activity with IC50 values ranging from 6.5 ± 0.6 to 14.7 ± 1.6 µM. Furthermore, two compounds (11 and 12) demonstrated moderate anti inflammatory activity, with IC50 values ranging from 24.1 ± 1.2 to 62.5 ± 1.9 µM.

Two new steroids, dendronesterones D (1) and E (2), featuring with 1,4-dienone moiety, along with three known steroids, methyl 3-oxochola-4,22-diene-24-oate (3), 5α,8α-epidioxy-24(S)- methylcholesta-6,22-dien-3β-ol (4), and 5α,8α-epidioxy-24(S)-methylcholesta-6,9(11),22-trien-3β-ol (5), were isolated from an octocoral Dendronephthya sp. The structures of steroids 1 and 2 were elucidated by using spectroscopic methods and steroid 1 was found to exhibit significant in vitro anti-inflammatory activity in lipopolysaccharides (LPS)-induced RAW264.7 macrophage cells by inhibiting the expression of the iNOS protein.

Raw264.7 Macrophage

Cissampelos pareira Linn. (C. pareira) has been used as a medicinal herb for treating fever and analgesic by Indian and Thai people. This experimental research investigates the scavenging ability of C. pareira pectin from leaves of variable concentrations on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and nitric oxide (NO) free radicals, its anti-inflammatory property on lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells, and the cell viability. The experimental results show that the DPPH and NO scavenging performances of C. pareira pectin are positively correlated to the pectin concentrations, with corresponding half maximal inhibitory concentrations (IC50)of 0.54 and 0.52 mg/ml. Meanwhile, the NO production in the LPS-stimulated macrophage cells is inversely correlated to the pectin concentrations. The cell viability in the LPS-stimulated macrophage cells is positively correlated to the C. pareira pectin concentrations, given the non-cytotoxicity of the extract compound. In essence, the inhibition of free radicals and the suppression of activated macrophages point to the usefulness of C. pareira pectin in functional dietary products and herb-based pharmaceuticals.

Besides being recorded as a traditional medicine, nowadays, plantain plants (Plantago sp.) are appreciated in many more aspects. Plantain is a name applied both to a drug and to a vegetable in a number of countries as Vietnam, China, Cambodia, Laos and North American Indians [9, 13]. Plantago sp. traditionally used for treating wound, fever and inflammation in Asia. This study aimed to investigate the anti-inflammatory activity of ethanolic extracts of Plantago sp. including P. major L. and P. depressa Willd. on RAW 264.7 murine macrophage cells. Cells were treated with different concentration of the PAE extract (50, 100, 200, 400 μg/mL) with or without lipopolysaccharide (LPS) stimulation to evaluate its effect on cell viability, using CCK-8 assay. Nitric oxide (NO) production was assessed by Griess reagent on LPS-stimulated cells using preceding PEE treatment. Furthermore, mRNA expression of inflammmatory-related genes were evaluated by RT-PCR analysis. The results revealed that PEE treatment increased cell viability in naive cells whereas inhibited cell profileration in LPS-stimulated cell dose-dependently. In addition, NO emission and mRNA level of IL-1β, IL-6, iNOS, COX-2 and NF-κB decreased by dose dependant manner. As summary, PEE exhibits anti-inflammatory activity through inhibition of pro-inflammatory mediators mRNA expression in macrophages.

Populus deltoides, known as eastern cottonwood, has been commonly used as a medicinal plant. The aim of the present study was to investigate the mechanism underlying the anti-inflammatory activity of P. deltoides leaf extract (PLE). PLE effectively inhibited the expression of inducible nitric oxide synthase (iNOS) and nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells, but not that of cyclooxygenase-2 (COX-2) and prostaglandin E2. Proinflammatory tumor necrosis factor alpha (TNF-α) levels were also reduced by the extract. PLE inhibited the phosphorylation of nuclear factor-kappa B (NF-κB) and inhibitor of Kappa Bα (IκBα), and blunted LPS-triggered enhanced nuclear translocation of NF-κB p65. In mitogen-activated protein kinase (MAPK) signaling, PLE effectively decreased the phosphorylation of p38 and c-Jun N-terminal protein kinase (JNK), but not of extracellular signal-regulated kinase 1/2 (ERK1/2). Taken together, these results suggest that anti-inflammatory activity of P. deltoides leaf extract might be driven by iNOS and NO inhibition mediated by modulation of the NF-κB and p38/JNK signaling pathways.

In this study, we aimed at evaluating in vitro and in vivo anti-inflammatory activity of various extracts of the rhizomes of Globba pendula Roxb. Three extracts ( n-hexane, ethyl acetate, and water) were screened for their inhibitory effect on NO production by lipopolysaccharide-stimulated RAW 264.7 macrophages. The ethyl acetate extract of G. pendula rhizomes (EGP) showed a potential effect with an IC50 value of 32.45 µg/mL. For in vivo study, the ethyl acetate extract was further investigated for its anti-inflammatory effect using collagen antibody-induced arthritic mice (CAIA). The level of arthritis in experimental mice significantly reduced ( P < .05) after treatment with EGP at a dose of 500 mg/kg body weight (b.w.). This study also revealed that EGP is orally non-toxic. Ethyl p-methoxy cinamate was identified as the main constituent of EGP, which may result in its anti-inflammatory effect.
