Abstract Background Drugs used for the treatment of diseases associated with chronic inflammation, such as cancer and rheumatoid arthritis have the potential to cause undesirable side-effects, which might result in patients ending treatment prematurely. However, plants are a viable option for the treatment of inflammatory diseases. In this study, we assessed the in vivo and in vitro anti-inflammatory activity, and the antitumor effects of the chloroform extract of Salvia ballotiflora (ECL). The pro-apoptotic effects of ECL in CT26 cells were also determined. Methods The chloroform extract of Salvia ballotiflora (ECL) was standardized using 19-deoxyicetexone (DEOX) as a phytochemical marker. The anti-inflammatory activity of ECL was determined on acute and chronic inflammatory models using the TPA-induced mouse ear edema assay. The antitumor activity of ECL was evaluated by the subcutaneous inoculation of CT26 cells on the back of Balb/c mice. In vitro CT26 cell death induced by ECL was determined by Annexin V/propidium iodide staining assay using flow cytometry. ECL and the diterpenes isolated from the chloroform extract included 19-deoxyicetexone (DEOX), icetexone (ICT), and 7,20-dihydroanastomosine (DAM), which were tested in LPS-stimulated J774A.1 macrophages to quantify pro-inflammatory cytokine levels. The in vitro anti-arthritic activity of ECL was determined using the bovine serum protein (BSP) denaturation assay. Results ECL exerted anti-inflammatory activities in acute (84% of inhibition, 2 mg/ear) and chronic models (62.71%, at 100 mg/kg). ECL showed antitumor activity at 200 mg/kg and 300 mg/kg, reducing tumor volume by 30 and 40%, respectively. ECL (9.5 μg/mL) induced in vitro apoptosis in CT26 cells by 29.1% (48 h of treatment) and 93.9% (72 h of treatment). ECL (10 μg/ml) decreased levels of NO (53.7%), pro-inflammatory cytokines IL-6 (44.9%), IL-1β (71.9%), and TNF-α (40.1%), but increased the production of the anti-inflammatory cytokine IL-10 (44%). The diterpenes DEOX, ICT, and DAM decreased levels of NO (38.34, 47.63, 67.15%), IL-6 (57.84, 60.45, 44.26%), and TNF-α (38.90, 31.30, 32.83%), respectively. ECL showed in vitro antiarthritic activity (IC50 = 482.65 μg/mL). Conclusions ECL exhibited anti-inflammatory and anti-tumor activities. Furthermore, the diterpenes DEOX, DAM, and ICT showed anti-inflammatory activity by reducing levels of NO, TNF-α, and IL-6.

The methanol, ethanol and chlorofom leaf extracts of Satkara, Citrus assamensis (family: Rutaceae), were subjected to in vitro anti-bacterial, thrombolytic, membrane stabilizing and in vivo anti-inflammatory and antitumor activity tests. The chloroform extract of C. assamensis showed the most important spectrum of activity against Bacillus subtilis, Bacillus cereus, Sarcina lutea among 6 gram positive and against 11 gram negative bacteria at the concentration of 1000 μg/disc, while the range of zones of inhibition were within 7-16 mm. Among the tested three extracts CHCl3 extract showed potent thrombolytic activity and hypotonic solution induced haemolytic activity where the percentages of inhibition were found to be 35% and 55% respectively. All the extracts established significant (p<0.05) anti-inflammatory effect by regulating biphasic inflammatory process induced by carrageenan. The leaf extract dose-dependently and significantly decreases the number of EAC cell count and inhibition of cell growth in comparison to the EAC control and standard. The results obtained in the present study indicate that, C. assamensis leaf can be a potential source of anti-bacterial, thrombolytic, membrane stabilizing, anti-inflammatory and antitumor agents.

Abstract The severity and perseverance of the inflammation have been demonstrated in many health conditions. The limitations of existing medications, propose the need for newer alternative anti-inflammatory medications. In our earlier studies, we demonstrated the topical anti-inflammatory potential of crude ethanolic extract of Tetrastigma sulcatum leaves and its fractions. In the present study, we further explored anti-inflammatory activity of T. sulcatum extract, fractions, pure compound and its derivatives using in vitro and in vivo bioassay techniques. We attempted to isolate a pure compound from leaf extract and was identified as Friedelan-3β-ol (CI) and its derivatives Friedelinol acetate (C II) and Friedelinol methyl ether (C III) were synthesized. Treatment with crude extract and its fractions demonstrated a significant reduction in the mRNA expression levels of pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) and nitric oxide (NO) production in LPS-stimulated inflammation in RAW 264.7 cells. Likewise, compounds CI, CII and CIII showed a similar pattern of significant inhibition of proinflammatory cytokines and NO production. In vivo study in Carrageenan induced paw-inflammatory mice model demonstrated reduced paw oedema and proinflammatory cytokines levels in a dose-dependent manner upon treatment of extract, its fractions, pure compound (CI), and their derivatives (CII and CIII.). The docking study showed all the compounds (CI, CII and CIII) share common residues with Dexamethasone. TNF- α exhibited the most interacting residues with the compounds. The present study confirmed the T. sulcatum ’s anti-inflammatory activity, suggesting Friedelan-3β-ol as an active component in a crude extract.

Several antibiotics demonstrate both antibacterial and anti-inflammatory/immunomodulatory activities and are used to treat inflammatory pulmonary disorders. Lefamulin is a pleuromutilin antibiotic approved to treat community-acquired bacterial pneumonia (CABP). This study evaluated lefamulin anti-inflammatory effects in vivo and in vitro in a lipopolysaccharide-induced lung neutrophilia model in which mouse airways were challenged with intranasal lipopolysaccharide. Lefamulin and comparators azithromycin and dexamethasone were administered 30min before lipopolysaccharide challenge; neutrophil infiltration into BALF and inflammatory mediator induction in lung homogenates were measured 4h postchallenge. Single subcutaneous lefamulin doses (10‒140mg/kg) resulted in dose-dependent reductions of BALF neutrophil cell counts, comparable to or more potent than subcutaneous azithromycin (10‒100mg/kg) and oral/intraperitoneal dexamethasone (0.5/1mg/kg). Lipopolysaccharide-induced pro-inflammatory cytokine (TNF-α, IL-6, IL-1β, and GM-CSF), chemokine (CXCL-1, CXCL-2, and CCL-2), and MMP-9 levels were significantly and dose-dependently reduced in mouse lung tissue with lefamulin; effects were comparable to or more potent than with dexamethasone or azithromycin. Pharmacokinetic analyses confirmed exposure-equivalence of 30mg/kg subcutaneous lefamulin in mice to a single clinical lefamulin dose to treat CABP in humans (150mg intravenous/600mg oral). In vitro, neither lefamulin nor azithromycin had any relevant influence on lipopolysaccharide-induced cytokine/chemokine levels in J774.2 mouse macrophage or human peripheral blood mononuclear cell supernatants, nor were any effects observed on IL-8‒induced human neutrophil chemotaxis. These in vitro results suggest that impediment of neutrophil infiltration by lefamulin in vivo may not occur through direct interaction with macrophages or neutrophilic chemotaxis. This is the first study to demonstrate inhibition of neutrophilic lung infiltration and reduction of pro-inflammatory cytokine/chemokine concentrations by clinically relevant lefamulin doses. This anti-inflammatory activity may be beneficial in patients with acute respiratory distress syndrome, cystic fibrosis, or severe inflammation-mediated lung injury, similar to glucocorticoid (eg, dexamethasone) activity. Future lefamulin anti-inflammatory/immunomodulatory activity studies are warranted to further elucidate mechanism of action and evaluate clinical implications.

Objective: The study aimed to evaluate the anti-inflammatory activity of Amomum subulatum (greater cardamom) seed and rind extracts in Wistar rats. Methods: The seed and rind of A. subulatum were air-dried in the shade, powdered, and subjected to 80% hydroalcoholic extraction in the Soxhlet apparatus. The anti-inflammatory activity of the seed and rind extracts of A. subulatum was evaluated by in vivo and in vitro methods. Results and Discussion: In vivo studies, namely, carrageenan-induced rat paw edema, cotton pellet granuloma, and formaldehyde-induced arthritis model confirmed the anti-inflammatory potential of seed and rind extracts of A. subulatum. It was found that rind extract exhibited better inhibition of inflammation as compared to seed extract. A. subulatum rind extract at the dose of 500 μg/ml exhibited best results for in vitro studies, namely, inhibition of albumin denaturation (73% inhibition), antiproteinase action (58% inhibition), membrane stabilization, heat-induced hemolysis, hypotonicity-induced hemolysis (54% inhibition), anti-lipoxygenase activity. Conclusions: The results of the study showed that the rind extract of A. subulatum (greater cardamom) possesses significant anti-inflammatory potential in various in vivo and in vitro anti-inflammatory models in the experimental animals.

The study was aimed to evaluate the analgesic and anti-inflammatory activity (by both in-vitro and in-vivo) of both chloroform and methanol root extracts of Andrographis serpyllifolia (Rottl. Ex Vahl.) Wt. Methods used for the studies were In-vitro 5-Lipoxygenase inhibition assay and In-vivo measurement of rat paw edema and ear edema in rats, acetic acid induced writhing response and hot plate method in albino mice. Chloroform and methanolic extracts of A. serpyllifolia root have shown moderate potency in inhibiting 5-LOX and shown significant anti-inflammatory activity. Despite the IC50 values are little higher, anti-inflammatory efficacy of these extracts possibly due to other mechanisms apart of 5-LOX inhibition. However, In-vivo anti-inflammatory studies revealed that A. serpyllifolia methanolic extract has shown higher degree of efficacy when compared to the chloroform extract. In terms of analgesic activity in writhing test, methanolic extract has shown more efficacy than chloroform extract. Hence, it is important to isolate the active principles for further testing the anti-inflammatory efficacy.DOI: http://dx.doi.org/10.3329/icpj.v1i8.11250 International Current Pharmaceutical Journal 2012, 1(8): 199-204

Background: Topical application of herbs is one of the recommended treatment modalities for Osteoarthritis (OA) in Ayurveda (Indian system of medicine). The current study intended to evaluate the anti-inflammatory effect of a polyherbal powder used as Upanaha (poultice) for OA by in vitro and in vivo techniques. Materials and Methods: The polyherbal formulation Upanaha Choornam (UC) was sourced from Vaidyaratnam Oushadhasala (P) Ltd., Thrissur, India. Changes in the secretion of TNF-α and NO and expression of Cox-2 genes were evaluated by semi quantitative PCR activity to establish anti-inflammatory action in vitro. Macrophages and connective tissue of mice were used as media for the former two experiments and only macrophages for the latter. In vivo anti–inflammatory activity was evaluated by TPA induced ear oedema in Swiss Albino mice (n=24), divided into 4 groups as Group I - saline treatment, Group II - Indomethacin treatment, and Groups III and IV treated with 30% and 60% of UC respectively. Results: In the in vitro study, UC at 1000 µg/ml and 500 µg/ml upregulated the COX-2 level by 0.08 and 0.03 folds respectively as compared to control. Release of TNF-α, and NO in LPS-induced RAW cells were significantly inhibited in a dose dependent manner. The TPA induced ear oedema significantly reduced in Groups III and IV (F=1250, p less than 0.001) Conclusion: The current study demonstrates the safety and anti-inflammatory activity of a polyherbal formulation Upanaha Choornam as a topical application. This indicates the potential of select herbs in managing degenerative conditions like OA.

Wheat germ is rich in quinones that exist as glycosides. In this study, we used Celluclast 1.5L to release the hydroxyquinones, which turn into benzoquinone, and prepared the water extract from enzyme-treated wheat germ (EWG). We investigated whether enzyme treatment altered the anti-inflammatory activity compared to the water extract of untreated wheat germ (UWG). UWG inhibited the production of inducible nitric oxide synthase (iNOS) and interleukin (IL)-12 and induced the production of IL-10 and heme oxygenase (HO)-1 in lipopolysaccharide (LPS)-stimulated macrophages. Enzyme treatment resulted in greater inhibition of iNOS and IL-10 and induction of HO-1 compared to UWG, possibly involving the modulation of nuclear factor (NF)-κB, activator protein 1 (AP-1) and nuclear factor erythroid 2-related factor (Nrf2). Mice fed UWG or EWG had decreased serum tumor necrosis factor (TNF)-α and increased serum IL-10 levels after intraperitoneal injection of LPS, with UWG being more effective for IL-10 and EWG more effective for TNF-α. Hepatic HO-1 gene was only expressed in mice fed EWG. We provide evidence that enzyme treatment is a useful biotechnology tool for extracting active compounds from wheat germ.

Momordica charantia L., or bitter melon, has been suggested to exhibit anti-inflammatory activity. In a previous study, three structurally similar triterpenes, namely 5β,19-epoxy-25-methoxycucurbita-6,23-diene-3β,19-diol (EMCD), 5β,19-epoxy-25-methoxycucurbita-6,23-dien-3β-ol (EMCO), and 5β,19-epoxy-19,25-dimethoxycucurbita-6,23-dien-3β-ol (EDMO), were isolated from bitter melon. EMCD has been shown to exhibit in vitro anti-inflammatory activity. In this study, the anti-inflammatory activities of EMCD, EMCO, and EDMO were compared. All three compounds were toxic to the RAW 264.7 macrophage cell line but not the FL83B cells. EMCD and EMCO inhibited tumor necrosis factor (TNF)-α-induced inducible nitric oxide synthase (iNOS) expression in FL83B cells, and the IC50 values were 19.8 and 25.7 μM, respectively. By contrast, EDMO did not effectively reduce iNOS expression. Furthermore, EMCD and EMCO suppressed other TNF-α-induced proinflammatory signals including the activation of inhibitor kappa B kinase complex, the phosphorylation of inhibitor of nuclear factor-κB, and the activation of c-Jun kinase. EMCD consistently exhibited a higher efficacy than did EMCO in these assays. Hence, the in vivo anti-inflammatory activity of EMCD was tested. EMCD clearly repressed 12- O-tetradecanoylphorbol-13-acetate (TPA)-induced ear edema in mice. In conclusion, differences in the functional group on carbon 19 do affect the anti-inflammatory activities of EMCD, EMCO, and EDMO. EMCD exhibited the highest anti-inflammatory activity among these molecules, and its in vivo anti-inflammatory activity was confirmed.

Aucklandia lappa DC., Terminalia chebula Retz and Zingiber officinale Roscoe have been traditionally used in east Asia to treat chronic diarrhea and abdominal pain. This study aimed to evaluated the anti-inflammatory activity of KM1608, which is composed of three natural herbs in a mouse model of dextran sodium sulfate (DSS)-induced ulcerative colitis. The anti-inflammatory activity and underlying mechanism were assessed in vitro using LPS-treated RAW264.7 cells. The in vivo effect of KM1608 on DSS-induced colitis was examined after oral administration in mice. KM1608 significantly inhibited the inflammatory mediators such as nitric oxide, interleukin (IL)-6, monocyte chemotactic protein 1 (MCP-1) and tumor necrosis factor (TNF)-α in LPS-treated RAW264.7 cells. The inhibitory effect of KM1608 was attributed to the reduction of Akt phosphorylation in the LPS-treated cells. In the mouse model, oral administration of KM1608 significantly improved DSS-induced colitis symptoms, such as disease activity index (DAI), colon length, and colon weight, as well as suppressed the expression of IL-6, TNF-α, and myeloperoxidase (MPO) in the DSS-induced colitis tissues. Taken together, KM1608 improved colitis through the regulation of inflammatory responses, suggesting that KM1608 has potential therapeutic use in the treatment of inflammatory diseases.

Flavonoids, widely present in medicinal plants and fruits, are known to exhibit multiple pharmacological activities. In this study, we isolated a flavonoid compound, pilloin, from Aquilaria sinensis and investigated its anti-inflammatory activity in bacterial lipopolysaccharide-induced RAW 264.7 macrophages and septic mice. Pilloin inhibited NF-κB activation and reduced the phosphorylation of IκB in LPS-stimulated macrophages. Moreover, pilloin significantly suppressed the production of pro-inflammatory molecules, such as TNF-α, IL-6, COX-2 and iNOS, in LPS-treated RAW 264.7 macrophages. Additionally, pilloin suppressed LPS-induced morphological alterations, phagocytic activity and ROS elevation in RAW 264.7 macrophages. The mitogen-activated protein kinase-mediated signalling pathways (including JNK, ERK, p38) were also inhibited by pilloin. Furthermore, pilloin reduced serum levels of TNF-α (from 123.3 ± 7 to 46.6 ± 5.4 ng/mL) and IL-6 levels (from 1.4 ± 0.1 to 0.7 ± 0.1 ng/mL) in multiple organs of LPS-induced septic mice (liver: from 71.8 ± 3.2 to 36.7 ± 4.3; lung: from 118.6 ± 10.6 to 75.8 ± 11.9; spleen: from 185.9 ± 23.4 to 109.6 ± 18.4; kidney: from 160.3 ± 11.8 to 75 ± 10.8 pg/mL). In summary, our results demonstrate the anti-inflammatory potential of pilloin and reveal its underlying molecular mechanism of action.
