Abstract This study aimed to investigate antioxidant and anti-inflammatory activities of a commercial product of noni (Morinda citrifolia) juice. Carrageenan-induced rat paw edema was employed as inflammatory model. One control and three experimental groups were formed. Experimental groups were administered noni juice alone, noni juice+carrageenan, and carrageenan alone. Oxidant and antioxidant capacity were determined by d-ROMs test and BAP test, respectively. Plasma concentrations of endothelin-1 and leptin were measured by ELISA. Measurements were performed at zero time and 2nd hour of inflammation. Oxidant capacity decreased in noni-received groups at 2nd hour (p=0.019). Antioxidant capacity of the group which received noni alone was found to be higher at 2nd hour (p=0.036). Plasma concentrations of endothelin-1 and leptin were notably lower in noni-received groups (p=0.001 and p=0.021, respectively). The results show that the commercial noni juice investigated has pronounced antioxidant and anti-inflammatory activities.

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.

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.

We have developed a series of aminoacetylenic isoindoline-1,3-dione compounds and showed their anti-inflammatory activities by reducing carrageenan-induced rat paw edema and modulating proinflammatory and anti-inflammatory cytokines. In the present study and due to efficacy reasons, we are exploring only two of these compounds, namely, ZM4 and ZM5, to reveal their analgesic activity and toxicity. Following oral administration, both compounds were effective in reducing significantly (P<0.05–0.001) acetic acid-induced writhing behavior, hot plate latency test, and formalin-induced paw licking time as antinociceptive indicators in mice and rats, respectively. Regarding the toxicity, the acute (20, 50, and 150 mg/kg) and repeated oral administration (10, 20, and 50 mg/kg) of these compounds for ten days did not produce any mortality and the compounds were considered well tolerated. However, repeated oral administration of 50 mg/kg of both compounds induced erythropoiesis by means of increasing significantly red blood cells, hemoglobin, and packed cell volume. Moreover, these compounds did not induce gastric lesions in the stomach of experimental animals at the doses that exhibited analgesic and anti-inflammatory activity compared to indomethacin as a positive control. The results indicate that ZM4 and ZM5 possess potential analgesic activity while being preliminarily safe and have minimal ulcerogenic activity.

Many scientists study structure and charagterization of placenta and experimenting on their biological activity, due to develop new drugs and biopreparation for human and animal health. The present study aimed to isolate bovine placental lactogen from placenta by semi purification method and determine antioxidant, anti-inflamatory activity and effect on immune responses was also investigation. Semi purified protein was separated  by gel-chromatographic method using 3 methods of tissue homogenizations of placental tissue using distilled water, phosphate buffer saline and Tris-HCl, by use of 4 methods of protein extraction and precipitation with distilled water, sulfate ammonium salt and organic solvents, such as ethanol and acetone.Antioxidant activity of semi purified  protein was measured by DPPH method, effect on immunity was investigated by using MTT assay kit, and anti-inflammatory activity was measured by using 1 % carrageenan-induced rat paw edema models. Measurements of total proteins which were homogenized in PBS, followed by acetone precipitation is 6217.5 µg/ml is the highest and homogenized in PBS, followed by sulfate ammonium salt precipitation is 1477.4 µg/ml is the lowest concentration. Bovine placental extract DPPH radical scavenging activity was 55.1±1.2% and rutin was 67.1±1.2% but results of immunity experiment demonstrated splenocyte division in placental extract added medium for stimulation index 1.45 or splenocyte culture increased by 1.5 times than as compared to those in medium not added placental extract, as well as placental extract added in the medium stimulation index increased 1.08 or splenocyte division by 0.8 times or almost the same than those wells with culture treated with mitogen only. Semi-purification placental protein was inhibition on 1% carrageenan induced rat paw edema and it means bovine placental extract effectively reduce acute inflammation.
