Abstract Excessive intake of non-steroidal anti-inflammatory drugs such as, diclofenac sodium (DS) may lead to toxicity in the rats. In this work, we aimed to examine the protective impact of lentil extract (LE) and folic acid (FA) on the hematological markers, the kidney tissue oxidative stress and the renal function against diclofenac sodium (DS) in male albino rats. The rats (120-150 g) were divided into four equal groups randomly, the first group kept as the untreated control. The second group was administrated with DS (11.6 mg/kg b.wt. orally once/day). The third group was received DS+FA (11.6 mg/kg b.wt.+76.9 microgram/kg b.wt.) orally once/day. The fourth group was treated with DS+LE (11.6 mg/kg b.wt.+500 mg/kg b.wt.) orally once/day. After four weeks, the results revealed that DS produced a significant decrease in the values of red blood cells (RBCs), hemoglobin concentration (Hb), hematocrit (HCT) and white blood cells (WBCs). On the other hand, there was a significant increase in the platelets count. Also, DS induced a renal deterioration; this was evidenced by the significant increase in the serum levels of urea, creatinine, uric acid, Na, Ca, Mg as well as the nitric oxide (NO) level in the kidney tissue. Also, there were a significant reduction in the serum levels of potassium (K) and reduced glutathione (GSH) in the kidney homogenates. Moreover, the findings in the rats treated by DS+LE or DS+FA showed a potential protection on the hematological markers, oxidative stress in the kidney tissue and the renal function disturbed by DS. LE and FA could play a potent role for the prevention the adverse hematological, the kidney tissue oxidative stress and the renal dysfunction caused by DS via their anti-oxidative and bioactive phytochemicals.

Qurs Afsanteen Saghir is a polyherbal Unani formulation in the form of tablet. This formulation consists of multiple medicinal plants like Afsanteen (Artemisia absinthium L.), Badam Talkh (Prunus dulcis (Mill.) D.A.Webb), Asaroon (Asarum europaeum L.), Anisoon (Pimpinella anisum L.) and Tukhm-e-Karafs (Apium graveolens L.). The clinical adult dose of study drug is 3.5 –7 g per day as mentioned in Unani literature. The present study evaluated the antipyretic, analgesic and anti-inflammatory potential of Qurs Afsanteen Saghir using different animal models. Antipyretic activity was measured using yeast-induced pyrexia model in rats at 360 and 720 mg/kg bw dose of test drug and paracetamol (70 mg/kg bw p.o.) as standard control. Analgesic effect was evaluated using acetic acid-induced writhing test in mice using test drug at dose 720 and 1440 mg/kg bw and diclofenac sodium (15 mg/kg bw p.o.) as standard control. Eddy’s hot plate test was conducted in rats using test drug at the dose of 360 and 720 mg/kg bw and buprenorphine (0.10 mg/kg s.q.) as standard control. Anti-inflammatory activity was assessed by carrageenan-induced paw edema model in rats with the dose of 360 and 720 mg/kg of test drug and Indomethacin (10 mg/kg p.o.) as standard control. The study drug significantly reduced the temperature and pain at both dose levels in a time-dependent manner as compared to normal control. However, the reduction of inflammation was observed at low dose (360 mg/kg bw) only after 3 hours of carrageenan administration. These findings indicated that tested drug showed potential activity as antipyretic and analgesic; whereas the drug may not be considered quite effective as an anti-inflammatory agents.

Diclofenac sodium (DCF) is a non-steroidal anti-inflammatory drug mainly used as an analgesic, arthritic and anti-rheumatic. This study deals with the degradation of diclofenac by photo catalytic-based advanced oxidation processes. Artificial UV lamp and solar rays have been applied to activate the ZnO catalyst, thereby generating highly oxidizing species. These species initiate the degradation process of the drug, which results in intermediates that finally dissociate into carbon dioxide and water. The solar reactor system is comprised of quartz and borosilicate tubes alternatively for the absorption and transmission of the solar rays to the pollutant sample. The degradation rate has been analyzed by composition analysis using high performance liquid chromatography. TOC and COD tests have also been conducted for degraded samples. ZnO catalyst loading was tested from 0.1 gm/L to 1 gm/L and the degradation rate showed a rising trend up to 0.250 gm/L, but further increase in loading resulted in a drop in degradation. Similarly, degradation is higher in acidic condition as compared to neutral or basic pH. The results showed a higher degradation rate for UV lamp irradiation as compared to the solar system. Moreover, TOC and COD reduction is also found to be higher for UV lamp photo catalysis.

The purpose of the present research was to synthesize a new series of acetanilide derivatives that would have analgesic and anti-inflammatory properties in laboratory animals (rats). IR spectroscopy, 1HNMR spectroscopy and Mass spectroscopy were used to confirm the structures of freshly synthesised compounds. The goal of the computer analysis of synthesized compounds was to see how similar they were in terms of physicochemical properties. For this, physiochemical parameters were calculated. The result suggested the reasonable physiochemical similarity with diclofenac sodium and Indomethacin. Molecular docking studies showed that the all the test compounds perfectly docked with COX-2 enzyme with all the drug-likeness characteristics. Before start of in-vivo evaluation, in vitro cyclooxygenase (COX) inhibition assays was performed with an aim to evaluate the compounds against the protein target COX-2 which would exhibit their inhibitory activity. The test compounds (C1-C6) were subjected to analgesic activity evaluation by Eddy’s hot plate method and anti-inflammatory activity evaluation by Carageenan induced edema method respectively.

The present study focuses on the investigation of methanol extracts of roots of three indigenous plants of Bangladesh namely Acacia nilotica, Azadirachta indica and Justicia adhatoda to evaluate their analgesic and hypoglycemic activities in experimental animal model along with in silico modelling of several compounds present in the root extracts of these plants. Analgesic and hypoglycemic activities were evaluated in Swiss albino mice using acetic acid-induced writhing inhibition method and glucose tolerance test, respectively. In silico molecular docking and ADME study was conducted to assess the binding affinity with the target receptors and oral bioavailability of the compounds. The methanol extracts of A. nilotica, J. adhatoda and A. indica roots at a dose of 400 mg/kg body weight reduced the number of writhes by 61.53%, 54.61% and 47.69%, respectively compared to standard diclofenac sodium (70.77% at a dose of 50 mg/kg bw) (p<0.05). A. nilotica and A. indica root extracts showed significant hypoglycemic activity at a dose of 400 mg/kg bw (% reduction of blood glucose 43.66 and 37.55% respectively, p<0.001) and J. adhatoda root extract reduced the blood glucose level by 33.71% (p<0.001) compared to that of standard drug, glibenclamide (57.46% reduction of blood glucose) after 120 minutes of administration. Among the computationally tested compounds, flavan-3-ol showed the lowest binding energy (-8.7 kcal/mol) with both COX-1 and COX-2 compared to standard diclofenac sodium (-7.8 kcal/mol). On the other hand, quercetin demonstrated the lowest binding energy (-8.8 kcal/mol) with ATP-sensitive potassium channel with Sulfonylurea Receptor 1 subunit among the tested compounds compared to standard glibenclamide (-9.3 kcal/mol). All the compounds showed high oral bioavailability in ADME analysis. Among all the root extracts, A. nilotica exhibited the most promising analgesic and hypoglycemic activities and should be employed to future investigation for isolating specific chemical constituents.

In Bangladesh, numerous tribal people of Chittagong Hill Tracts have been using different parts of Thysanolaena maxima Roxb. for many years. The present study was designed to investigate CNS depressant and analgesic activities of methanol extract of the aerial parts of the plant in mice models. CNS depressant activity of the crude extract (200 and 400 mg/kg) was evaluated using open field, hole cross and thiopental-induced sleeping time tests using diazepam as the standard. Analgesic activity was determined using acetic acid-induced writhing and hot plate tests using diclofenac sodium as the standard. The extract showed dose dependent suppression of locomotion in open field and hole cross tests and exerted sedative action in thiopental induced sleeping time. In the open field and the hole-cross tests, maximum CNS depressant activity was observed at 90 min after administration of extract and the standard drug. The extract significantly induced the onset of sleep and prolonged the sleeping time in thiopental induced sleeping test compared to the control group. The extract produced significant (p < 0.05) analgesic activity by inhibiting writhing by 41.89% and 60.81%, at doses of 200 and 400 mg/kg body weight, respectively, which was comparable to the inhibition of diclofenac sodium (73.64%). Additionally, in hot plate test, the extract exhibited a significant (p < 0.05) increase in pain threshold in a dose dependent manner. The findings of the study are encouraging and demands further investigation of other bioactivities with isolation of pure compounds. Dhaka Univ. J. Pharm. Sci. 20(2): 227-233, 2021 (December)

Steroid sapogenin diosgenin is of significant interest due to its biological activity and synthetic application. A consecutive one-pot reaction of diosgenin, oxalyl chloride, arylacetylenes, and phenylhydrazine give rise to steroidal 1,3,5-trisubstituted pyrazoles (isolated yield 46–60%) when the Stephens–Castro reaction and heterocyclization steps were carried out by heating in benzene. When the cyclization step of alkyndione with phenylhydrazine was performed in 2-methoxyethanol at room temperature, steroidal α,β-alkynyl (E)- and (Z)-hydrazones were isolated along with 1,3,5-trisubstituted pyrazole and the isomeric 2,3,5-trisubstituted pyrazole. The consecutive reaction of diosgenin, oxalyl chloride, phenylacetylene and benzoic acid hydrazides efficiently forms steroidal 1-benzoyl-5-hydroxy-3-phenylpyrazolines. The structure of new compounds was unambiguously corroborated by comprehensive NMR spectroscopy, mass-spectrometry, and X-ray structure analyses. Performing the heterocyclization step of ynedione with hydrazine monohydrate in 2-methoxyethanol allowed the synthesis of 5-phenyl substituted steroidal pyrazole, which was found to exhibit high anti-inflammatory activity, comparable to that of diclofenac sodium, a commercial pain reliever. It was shown by molecular docking that the new derivatives are incorporated into the binding site of the protein Keap1 Kelch-domain by their alkynylhydrazone or pyrazole substituent with the formation of more non-covalent bonds and have higher affinity than the initial spirostene core.

We investigated the in vivo effect of curcumin nanoparticles (nC) in addition to diclofenac sodium on local edema and oxidative stress parameters in carrageenan-induced paw edema on rats. Seven groups were investigated: control group (C), the acute inflammation (AI) group, an AI group treated with Diclofenac (AID, 5 mg/kg b.w. Diclofenac sodium), two AI groups treated with cC (conventional Curcumin)—AIC200 and AIcC200D (D = Diclofenac, 200 represent the concentration of active substance expressed in mg/kg b.w.), and two AI groups with nC (Curcumin nanoparticles)—AIC200 and AIcC200D. Serum and tissue oxidative stress was assessed by measuring five parameters. Curcumin nanoparticles alone and in combination with D better reduced the paw edema than D alone (p < 0.027). The rats treated with D and nC (AIcC200D) had the highest inhibition percentage on edema, reaching the maximum level of inhibition (81%) after 24 h. Conventional curcumin and nC presented antioxidant effects in acute inflammation, with significantly better results obtained for nC. The pro-oxidant markers were reduced up to 0.3 by the cC and up to 0.4 times by the nC and both solutions increased the antioxidant markers up to 0.3 times. The nC enhanced the antioxidative efficacy of D, as this combination reduced the pro-oxidant markers up to 1.3 times. Curcumin nanoparticles could represent a therapeutic option in association with classical nonsteroidal anti-inflammatory medication in acute inflammation, as they might offer a reduction of drug dose and possible limitation of their associated side effects.

Abstract PCA (protocatechuic acid), a phenolic compound found in teas, fruits and vegetables, is widely recognized with its antioxidant and anti-inflammatory activities. Here we verified the protective role of PCA on carrageenan-induced paw edema in mice. PCA (25 mg/kg and 50 mg/kg) administration was applied for five consecutive days prior to the carrageenan injection. Diclofenac sodium (20 mg/kg) was used as a reference drug. PCA pretreatment notably decreased the volume of the developed edema and alleviated the histopathological alterations induced by carrageenan. Additionally, PCA administration enhanced the cellular antioxidant capacity as demonstrated by the increased levels of catalase, superoxide dismutase and reduced glutathione, in addition to the decreased malondialdehyde level in the edematous tissue. Interestingly, PCA administration was able to suppress the developed inflammatory response upon carrageenan injection as indicated by the decreased levels and expression of pro-inflammatory cytokines and mediators including tumor necrosis factor alpha, interlukin-1 beta, interlukin-6, inducible nitric oxide synthase, nitric oxide, cyclooxygenase-II, prostaglandin E2, monocyte chemoattractant protein-1, myeloperoxidase and nuclear factor kappa B. These results collectively confirm the protective effect of PCA against carrageenan-induced paw edema owing to its antioxidant and anti-inflammatory characteristics.
