In this manuscript, the authors explore the antimicrobial and anti-inflammatory properties of extracts from two commonly found and used leaves from species Murraya koenigii and Ocimum gratissimum L., Ethanolic extracts were obtained by maceration and were then concentrated. Serial dilutions of the extracts were done for testing. The extracts were tested for growth inhibition of four bacterial and two fungal strains. Visual examination of growth inhibition, compared to standard antibiotic controls, provided minimum inhibitory concentrations for the two extracts against the six microbial strains. In another experiment, the authors test the anti-inflammatory properties of the two leaf extracts in the standard rat-paw model of inflammation. Results from growth inhibition studies suggest that the two leaf extracts inhibit the growth of all six microbes, with varying levels of sensitivity. Results from anti-inflammatory studies are more impressive, with leaf extracts inhibiting inflammation at levels competitive with the standard drug, indomethacin.

The present study was intended to evaluate Anti-inflammatory activity ofC. rottleriextracts (Hydroalcoholic, Methanol, Ethyl acetate and Hexane). The Anti-inflammatory activity ofC.rottleriextracts at doses of 125mg/kg, 250mg/kg and 500mg/kg using carrageenan induced rat paw edema model compared with standard drug (Indomethacin). The selected plant extracts significantly inhibited paw edema along with the standard drug Indomethacin. Of all extracts, methanol extract produced significant effect on reduction of increased paw thickness, hydro alcoholic and ethyl acetate extracts produced moderate percentage inhibition and hexane extract produced low level of percentage inhibition in reducing paw edema on carrageenan induced rats. In all extracts, methanol extract at a dose of 500mg/kg showed more percentage inhibition i.e . 53.47±2.19. From the results obtained during the study it is concluded thatC. rottlerihaving the bioactive molecule responsible for Anti-inflammatory activity by individually or by combination of different bio-active compounds present in it. Further is necessary for isolation and characterization of bioactive molecules which are responsible for the selected plant biological activities.

Before And After

Extracts of fresh and dry Ailanthus altissima leaves from Croatia were evaluated for their phenolic composition, antioxidant and antimicrobial activities. The methanolic extract had a higher concentration of total phenolics, flavonoids and non-flavonoids, as well as a higher antioxidant capacity than water extracts. Flavonoids identified in A. altissima leaves belong to two groups: flavones (glycosides of apigenin and luteolin) and flavonols (glycosides of quercetin and kaempferol). They were mainly present as glycosides, quercetin-3- O-glucoside was the predominant flavonoid. Only traces of aglycones were detected even after extract hydrolysis. Caffeic acid was the predominant phenolic acid both before and after hydrolysis, followed by chlorogenic acid after hydrolysis. The concentration of chlorogenic acid significantly increased soon after tissue fragmentation suggesting this compound is involved in rapid response against mechanical wounding in A. altissima. Therefore, to increase the chlorogenic acid concentration, mechanical wounding could be applied. The acetone leaf extract was as active against Escherichia coli as the positive control gentamicin. Both acetone and methanol:dichloromethane extracts had a higher activity against Candida albicans than a standard drug amphotericin B. Therefore, A. altissima could serve as a valuable resource for antimicrobial activity, which makes this species interesting for further investigation and possible pharmaceutical application.

Objective: Objective of the study was to synthesize and evaluate a series of novel compounds, ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)- 4,5-dimethylthiophene-3-carboxylates, for in vitro antioxidant and in vivo anti-inflammatory activities.Methods: Ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5-dimethylthiophene-3-carboxylates were synthesized by knoevenagel condensation of active methylene group of ethyl 2-(2-cyanoacetamido)-4,5-dimethylthiophene-3-carboxylate with substituted benzaldehydes. The synthesized compounds were evaluated for their in vitro antioxidant properties in three different models, viz., reduction of 1,1-diphenyl-2-pycrylhydrazyl free radical, scavenging of nitric oxide free radical, and ferric ion-induced lipid peroxidation using rat brain homogenate. Few selected compounds with good antioxidant properties were pharmacologically evaluated for anti-inflammatory activity by carrageenan-induced rat paw edema model.Results: Clean and efficient synthetic procedure was used for the preparation of series of compounds. The structures of synthesized compounds were confirmed by infrared, 1H nuclear magnetic resonance and mass spectra. The antioxidant activity data revealed that the compounds of ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5-dimethylthiophene-3-carboxylate containing phenolic substitution showed greater antioxidant activity. Hence, the active compounds were evaluated for anti-inflammatory activity and found to possess good activity. The percentage inhibition of rat paw edema obtained for the evaluated compounds was in the range of 70.2-83.1, comparable to the standard drug diclofenac (85.0%).Conclusion: The use of inexpensive, eco-friendly and readily available reagents, easy work-up and high purity of products makes the procedure a convenient and robust method for the synthesis of title compounds. The compounds of ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5- dimethylthiophene-3-carboxylate containing phenolic substitution showed greater antioxidant and anti-inflammatory activities.

Background: A new set of hybrid conjugates derived from 2-(4-isobutylphenyl)propanoic acid (ibuprofen) is synthesized to overcome the drawbacks of the current non-steroidal anti-inflammatory drugs. Results & methodology: Synthesized conjugates were screened for their anti-inflammatory, analgesic and ulcerogenic properties. Few conjugates were found to have significant anti-inflammatory properties in the carrageenan-induced rat paw edema test, while a fair number of conjugates showed promising peripheral analgesic activity in the acetic acid-induced writhing test as well as central analgesic properties in the in vivo hot plate technique. The newly synthesized conjugates did not display any ulcerogenic liability. Conclusion: In vitro, COX-1 and COX-2 enzyme inhibition studies raveled compound 7e is more selective toward COX-2 compared with ibuprofen.

The various extracts ofMerremia tridentatewere investigated for its anti-inflammatory and anti-arthritic activities in male albino rats. The anti-inflammatory activity was carried out using carrageenan-induced rat paw oedema model and the anti-arthritic activity was carried out using complete Freund’s adjuvant induced arthritis model. Indomethacin (10 mg/kg bw) was used as a standard drug. The ethanol extract ofM. tridentateexhibited significant dose dependent activity in acute inflammation and the doses of 100 mg/kg bw and 200 mg/kg bw produced 38.3% and 42.8% inhibition respectively after 3 h as compared with that of the standard drug which showed 48.5% inhibition. In arthritis model, the doses of 100 mg/kg bw and 200 mg/kg bw of the ethanol extract produced 49.0% and 51.7% inhibition respectively after 19 days when compared with that of the standard drug (55.5%). Both doses of the ethanol extract ofM. tridentateexhibit significant anti-inflammatory and anti-arthritic activities.

A wide scope of medical advantages has been credited to wheatgrass, the young grass of the wheat plant Tritium aestivum. Wheat grass is a decent wellspring of mineral supplements. It contains critical measures of iron, phosphorous, magnesium, manganese, copper and zinc. Wheatgrass is a rich supplement of tocopherols with high vitamin E content. Wheatgrass is beneficial in restoring more infections due to its significant function that, it can arrest the development of antagonistic microbes which are responsible for spreading certain diseases. constituents of wheatgrass may be obtained from fresh juice, frozen juice, powder, tablets with compositions differing as per their production methods which otherwise depends on growing conditions of wheatgrass. Anti-inflammatory activity of wheatgrass tablets was assessed by using formalin induced rat paw edema model. The results obtained were compared with aceclofenac, standard drug.
