BACKGROUND: Ziziphus jujuba belongs to family Rhamnaceae widely distributed in subtropical and tropical countries. It is used traditionally for several pharmacological purposes including anti-inflammation, antidiarrhoeal and antibacterial, as well as tonic and sometimes as hypnotic (sedative).AIM: To determine the in vivo antidiarrhoeal, antibacterial and anti-inflammatory activities of Z. jujuba fruit ethanolic extract.METHOD: The fruit was macerated and extracted by 95% (v/v) ethanol. The antidiarrhoeal activity was evaluated using castor oil and Escherichia coli induced diarrhoea mouse model. The antidiarrhoeal and antibacterial activity was investigated at graded doses (400-1200 mg/kg). The anti-inflammatory effects were tested using the carrageenan-induced paw oedema in female Wistar rats. Rat’s treatment groups received tragacanth, 100 mg/kg diclofenac sodium, 800 mg/kg, 1200 mg/kg or 1600 mg/kg of an ethanolic extract of Z. jujuba (EEZJ). All treatment groups were fed with the compounds one hour before carrageenan injection at of rat’s paw. Also, the EEZJ was further analysed by HPLC-PDA system for identification of the presence of betulinic acid and quercetin.RESULTS: EEZJ different doses did not show inhibitory activity against castor oil induced diarrhoea except for the higher (1200 mg/kg) dose. However, the frequency of defecation of stools and watery stool were reduced significantly when compared to control group (P ≤ 0.05 and P ≤ 0.01 respectively), resulted in overall 67% inhibition of diarrhoea. Our anti-inflammatory results demonstrated that EEZJ was able to inhibit the carrageenan-induced paw oedema in rats to a significant degree (p ≤ 0.05) and the paw volume and thickness of both left and right paw were affected compared to the negative control group.CONCLUSION: EEZJ possesses antidiarrhoeal and antibacterial activity in a dose depending manner and may provide a pharmacological basis for its clinical use in diarrheal diseases. The activity may partially be due to the presence of betulinic acid and quercetin.

This article reports the development of a pharmaceutical product containing vegetable actives from a Brazilian medicinal plant. The possibility of forming a microemulsion using Pterodon emarginatus ("sucupira") oil was evaluated and the anti-inflammatory potential of this microemulsion was also examined. A formulation was developed using P. emarginatus oil, a mixture of ethoxylated Castor Oil (Ultramone(r) R-540/propylene glycol 2:1) (surfactant/cosurfactant) and distilled water at a ratio of 10:15:75, respectively. The microemulsion which was selected was then subjected to the preliminary stability test and analyzed in terms of average diameter of droplets, pH, zeta potential, and polydispersity index, on the 1st, 7th, 15th, and 30th days after preparation and stored at different temperatures (5 ± 2 °C, 25 ± 2 °C, and 40 ± 2 °C). The anti-inflammatory in vivo activity of both oil and formulation were evaluated, using the experimental model of croton oil-induced ear edema. The preliminary stability test showed that the microemulsion stored at 5 and 25 °C retained its original features throughout the 30-day period. The anti-inflammatory potential of both oil and formulation was shown to be statistically significant (p < 0.001), when compared to the control group, however, the microemulsion proved to be more effective (p < 0.05) than the oil when applied directly to the ear.

Anti-inflammatory potential of the ethanol leaf extract of Sphenocentrum jollyanum (ELESJ) was assessed in-vivo in mice by using carrageenan-induced paw oedema, egg albumin-induced paw oedema, and xylene-induced ear oedema model at doses of 474.34, 948.68, and 1423.03 mg/kgbw respectively. A total of seventy-five matured mice of both sexes weighing between 20 g and 24 g (divided into three groups of 25 mice each for the 3 different studies) were used for this study. Treatment was done intraperitoneally. Distilled water (10 mL/kgbw), acetylsalicylic acid (ASA) (100 mg/kgbw) or dexamethasone (4 mg/kgbw) served as the normal and standard drugs respectively. The results showed that ELESJ produced significant (p < 0.05), dose-dependent and time-dependent reductions in mean paw thickness in groups III-V compared with control group. Similarly, the extract caused a dose-dependent increase in percentage inhibition of carrageenan-induced paw oedema and egg-albumin induced paw oedema (34.49%, 36.71%) at the highest dose (1423.03 mg/kg), comparable with the anti-inflammatory effects of the standard drug ASA (34.69%, 31.54%). The ELESJ also caused significant (p < 0.05), dose-dependent decreases in xylene-induced ear oedema weight in all the test groups relative to control group and standard drug group. In addition, ELESJ showed a dose-dependent percentage inhibitory effect (44%) at the highest dose (1423.03 mg/kg) comparable with that of the standard drug, dexamethasone (48%). The results obtained from this study support the use of the leaf in folk medicine as it has significant anti-inflammatory properties and this may be attributed to the phytochemical constituents of the leaf.

The present studies were executed on Freund's complete adjuvant (0.1 ml) induced arthritic Wistar rats to explore the folkloric use of the seeds. This study describes the effect of Punica granatum  Linn's Ethanolic (PGSE) and Chloroform (PGSC) extract within the FCA-induced arthritis rat paw oedema, vagaries in behaviour, haematological and alterations in biochemical parameters in the developed and progression of arthritis phases. There was a significant rise in the paw swelling (volume) of rats and reduction in (BW) body weight, with FCA-induced arthritic rats. In contrast, PGSE and PGSC with the dose of 200mg/kg and 400mg/kg and Diclofenac (20mg/kg) treated group showed a substantial decrease in paw volume and the normal improvement in body weight to the positive control group. The altered level of haematological parameters, including, Hb, RBC, WBC, and ESR, in arthritic rats, have been substantially regained to normal by PGSE and PGSC treatment at the dosage of 200 mg/kg/p.o and 400 mg/kg/p.o in both the developed and progression of arthritis phases. In this study, Anti-inflammatory action of the PGSE and PGSC with carrageenan-induced paw oedema has also been investigated. Thus, percentage (%) inhibition of PGSE and PGSC were found to be 91.8 % and 86.71, respectively, concerning Diclofenac sodium (93.14%), this gave the evidence of dose-dependent action potential of Punica granatum as anti-inflammatory activity.

Background: Lichens which are betide to mangroves are termed as Manglicolous Lichens (ML). As these ML are habituated under stress conditions, they are screened for unique metabolites and biological activities. Objective: The study aimed to establish the chemical and biological profile of ML, Graphis ajarekarii. Methods: The Ethyl Acetate Extract of G. ajarekarii (EAE) was subjected to chromatographic techniques and the obtained isolates were characterized by spectroscopic analysis. The hydroalcoholic extract of G. ajarekarii (AE), EAE, isolates and Hydroalcoholic Extract of host (HE) were evaluated for fibrinolytic (fibrin clot method), in vitro (protein denaturation method) and in vivo (formalin-induced rat paw oedema assay), anti-inflammatory and cytotoxicity (MTT assay) activities. Results: Chemical investigation of the EAE led to the isolation of two known compounds namely atranorin (1) and ribenone (2), which were confirmed by spectral data. The AE and EAE gradually lysed the fibrin clot with 94.54 and 65.07%, respectively, at 24 h. The AE inhibited protein denaturation of about 88.06%, while the standard (Indomethacin) with 93.62%. Similarly, the in vivo antiinflammatory analysis of AE (200 mg/mL) showed potent reduction of rat paw oedema than the standard, whereas EAE and 1 depicted moderate depletion. In addition, the AE revealed prominence inhibition on MCF-7, DU145 and K-562 with IC50 values of 69.5, 42.5 and 38 µg/mL, respectively, whereas the HE exhibited mild inhibitory profile against fibrin clot, inflammation and cancer. Conclusion: From the results, it can be concluded that the G. ajarekarii has an aptitude to act against coagulation, inflammation and cancer cells.

Abstract Objectives Several cultivars of Allium cepa L. have been studied for anti-inflammatory and analgesic activities but there is inadequate information on such biological activities of the concentrated extracts of the Nigerian grown red cultivar A. cepa bulb. Methods The anti-inflammatory models used in this study were Carrageenan-induced paw oedema and formalin-induced paw lick in rats, while acetic acid-induced abdominal writhing, hot plate reaction, hot water tail flick tests in mice were the analgesic models. Results At 30 min post-induction (pi), the inhibition of paw oedema (62.50%) by 200 mg/kg of methanol extract of red cultivar A. cepa bulb (MERCACB) was significantly (p<0.001) higher than that of indomethacin (15.63%) at 10 mg/kg. The paw oedema inhibition at 60 min pi by MERCACB (76.92%) was significantly higher than that of indomethacin (41.03%). At the early phase of formalin paw-lick test, the pain reaction time (PRT) of rat treated with MERCACB (400 mg/kg) was significantly lower than that of indomethacin and the control groups. The hotplate test revealed that PRT of mice treated with 800 mg/kg of MERCACB were significantly (p<0.01) longer in comparism to indomethacin and control groups. The PRT of mice subjected to thermal pain due to hot water and treated with 800 mg/kg of MERCACB was significantly (p<0.05) longer than that of the control group. Conclusions These findings indicate that MERCACB possesses potent anti-inflammatory and analgesic properties which confirm the traditional use of the plant for the treatment of inflammatory diseases and may be useful as a future therapeutic agent.

<p class="Abstract">In this study the antidiarrheal activity of ethanolic extracts of the leaves of <em>Mikania cordata</em> and <em>Litsea monopetala</em> was evaluated. Diarrhea was induced in mice by oral administration of castor oil (0.5 mL) 30 min after the administration of the extracts. During a 4 hour study the number of diarrheal feces and percentage inhibition of the extracts (200 and 400 mg/kg body weight) was determined. Loperamide (3 mg/kg body weight) served as standard and belonged to the positive control group. The extracts exhibited potent antidiarrheal activity as well as achieved statistically significant p value (p&lt;0.01 and p&lt;0.05) compared to control group. Among the extracts the highest percentage inhibition of defecation (60%) was recorded for leaf extract (400 mg/kg body weight) of <em>L. monopetala</em>. So, the study corroborates the significant antidiarrheal activity of <em>M. cordata</em> and <em>L. monopetala</em> leaf extracts and raises the demand of further sophisticated investigation.</p><p> </p>

Objective: The objective of this search was to synthesize a new naproxen analogues having a 1,2,4-triazole-3-thiol heterocyclic ring, and preliminary pharmacological assessment of the anti-inflammatory activity of the synthesized compounds. Methods: The synthesis of naproxen analogues that having 1,2,4-triazole-3-thiol heterocyclic ring occur through esterification of naproxen, and then its reaction with hydrazine hydrate, and carbon disulfide, finally different aromatic aldehydes reacted with triazole derivatives of naproxen containing amino group to produce schiff bases.Results: In vivo acute anti-inflammatory activity of the synthesize compounds (Va-Vd) was evaluated in rats using egg-white induced edema model of inflammation in a dose equivalent to (50 mg/kg) of naproxen. All tested compounds were produced a significant reduction in paw edema with respect to the effect of propylene glycol 50% v/v (control group). Compound Vd produced superior anti-inflammatory activity compared to naproxen.Conclusion: The results obtained in this work give evidence about the valid synthesis of 1,2,4 triazole-3-thiol derivatives of naproxen, which reacted with different aldehydes to yield several schiff bases. The incorporation of benzaldehyde possess para-electron donating group (para-hydroxyl benzaldehyde) will increase the anti-inflammatory activity of naproxen.

In the modern medicines the novel and active molecules are essential to act against various diseases and increase the needs day by day due to population increase. In view of that, we attempt to make a variety of synthetic molecules against inflammation by a new and popular greener microwave assisted and faster method such as Microwave Enhanced Chemistry assisted Vilsmeier Haack Synthesis (MEC-VHS). In this paper, we report the synthesis of nitro- dinitro- and acetyl- derivatives of 3- formyl, 7-flavonols using MEC-VHS techniques against inflammation as anti-inflammatory agent. These derivatives were synthesized via pinkish formylation complex of dimethyl formamide and phosphorous oxychloride by microwave irradiation resulted as suspension by base. The re-crystallized products were characterized through Co-TLC, λmax, IR, HPTLC, 1HNMR, CHN analysis and mass spectral studies. The HPTLC finger print profiles obtained were of with a prominent single peak and with a matching Rf values compared to that obtained by an ordinary Co-TLC technique. All the synthesized compounds were screened for their anti-inflammatory activity by in vitro protein denaturation method and in vivo carrageenan induced paw oedema method and it was found that all the compounds excepting the un-substituted 3-formyl, 7-flavonols gave an equi- or more potent activity as compared to that of the standard.
