Addressing quality medication use among migrant patients: Establishment of an organization to provide culturally competent medication care.

As the global landscape continues to witness an increase in migration, the healthcare community faces an evolving challenge: the provision of quality medication care to migrant patients. Language barriers, cultural differences, and a lack of understanding of the local healthcare system can often impede the effective management of medications and access to healthcare services among migrant populations. Pharmacists, as medication experts, are dignified to make a substantial impact in bridging the gap between migrants and quality healthcare. Their expertise in medication management, accessibility, and counseling positions them as critical healthcare providers for this patient population. Pharmacies and pharmacists can serve as trusted hubs where migrants receive not only essential medications but also culturally sensitive support in navigating the healthcare system. This commentary article highlights the critical importance of culturally competent medication care for migrant patients and the central role that pharmacists can play in this endeavor. By establishing organization dedicated to this cause lead by pharmacists, we can not only address an urgent healthcare concern but also set a precedent for a healthcare system that values inclusivity, cultural competence, and equitable access to quality medication care for all, regardless of their cultural background.

Cuminum cyminum Ameliorates Urotoxic Effects of Cyclophosphamide by Modulating Antioxidant, Inflammatory Cytokines, and Urinary Bladder Overactivity: In vivo and in Silico Investigations.

Interstitial Cystitis (IC) is a chronic inflammatory disease that lacks effective treatment. The present study aimed to investigate the potential of aqueous ethanol extract of Cuminum cyminum (AEECC) on oxidative stress, inflammation and overactivity of urinary bladder induced by cyclophosphamide (CYP). Female Sprague-Dawley rats received intraperitoneal administration of cyclophosphamide (150 mg/kg, i. p. 1st , 4th , and 7th days). To investigate the urothelial damage, the bladder weight, nociception behavior, and Evans blue dye extravasation method was used. The antioxidants CAT, GPX and NO were measured. ELISA determined the IL-6 and TNF-α levels. The spasmolytic effect of AEECC was investigated on isolated bladder strips and its mechanisms were determined. The enhanced nociception behavior, bladder weight, vascular permeability, edema, hemorrhage, nitric oxide, IL-6 and TNF-α levels by CYP administration were significantly reduced by AEECC (250 and 500 mg/kg). A significant increase in serum antioxidant system such as CAT and GPx was also observed in AEECC-treated rats. The AEECC (3 mg/ml) significantly reduced urinary bladder tone in the strips pre-contracted with carbachol in both control and CYP-treated rats. This relaxation was demolished by atropine, nifedipine, glibenclamide, and indomethacin but not with propranolol. The plant extract showed the presence of antioxidant and anti-inflammatory phytochemicals. These results suggest that Cuminum cyminum offers uroprotective activity and can ameliorate CYP-induced bladder toxicity by modulating antioxidant parameters, pro-inflammatory cytokine levels and bladder smooth muscle overactivity. The in silico binding interactions of antioxidant 2I3Y and anti-inflammatory protein 1TNF with various ligands from Cuminum cyminum seeds revealed potential bioactive compounds with promising antioxidant and anti-inflammatory properties, providing valuable insights for drug development and nutraceutical research.

Uroprotective Potential of Campesterol in Cyclophosphamide Induced Interstitial Cystitis; Molecular Docking Studies.

Cyclophosphamide (CYP) is commonly used to treat cancer of the ovaries, breast, lymph, and blood system and produces interstitial cystitis (IC) via its urotoxic metabolite: i. e., acrolein. The present study was aimed to investigate the uroprotective effect of campesterol (a steroidal phytochemical) in cyclophosphamide induced IC. IC was induced by CYP (150 mg/kg, i. p.) in rats. The Enzyme linked immunosorbent assays for oxidative stress markers and Polymerase Chain Reaction (PCR) for inflammatory cytokines were carried out. The Tissue Organ Bath Technique was used for the evaluation of the spasmolytic effect of campesterol. Different pharmacological antagonists have been used to explore the mechanism of action of campesterol. Treatment with campesterol (70 mg/kg) reduced nociception (55 %), edema (67 %), hemorrhage (67 %), and protein leakage significantly (94 %). The antioxidant activity of campesterol was exhibited by a fall in MDA, NO, and an elevation in SOD, CAT, and GPX levels. Campesterol presented anti-inflammatory potential by decreasing IL-1, TNF-α, and TGF-ß expression levels. Histologically, it preserved urothelium from the deleterious effect of CYP. Campesterol showed a spasmolytic effect by reducing bladder overactivity that was dependent on muscarinic receptors, voltage-gated calcium and KATP channels, and cyclo-oxygenase pathways. In silico studies confirmed the biochemical findings. The findings suggest that campesterol could be valorized as a possible therapeutic agent against cyclophosphamide-induced interstitial cystitis.

Evaluation of Hepatoprotective and Gastroprotective Activities of Paspalidium flavidum Leaves Extract in Experimental Animal Models.

Paspalidium flavidum (watercrown grass), a medicinal plant, is traditionally used in liver ailments and stomach problems. The hepatoprotective and gastroprotective activities of the aqueous methanol extract of Paspalidium flavidum (AMEPF) were studied in experimental animal models. Paracetamol and aspirin were used to induce hepatotoxicity and gastric ulcer in rats, respectively. Biochemical hepatic parameters, gastric pH, total acidity, ulcer index, percentage protection, nitric oxide and TNF-α were measured in AMEPF-treated groups. Moreover, GC-MS analysis of AMEPF was performed. Pretreatment with AMEPF improved the blood lipid profile and restored liver function tests in paracetamol-induced hepatotoxicity. While in aspirin-induced gastric ulcer, oral administration of AMEPF significantly reduced (P<0.05) the gastric lesions, total acidity and ulcer scoring index, TNF-α with upregulation of nitric oxide when compared with the Diseased group. AMEPF exhibited anti-lipid peroxidation activity. Histopathological studies were in good agreement with the biochemical findings. GC-MS analysis revealed the presence of anti-oxidant phyto-constituents, including oleic acid and 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) in AMEPF. This study suggested that aqueous methanol extract from the leaves of P. flavidum has beneficial hepatoprotective and gastroprotective activities related to its anti-oxidant phytochemicals.

Fabrication of pH responsive hydrogel blends of chondroitin sulfate/pluronic F-127 for the controlled release of ketorolac: its characterization and acute oral toxicity study.

OBJECTIVE: Ketorolac tromethamine (KT), selected as a model drug, is used in management of moderate to severe acute pain. It has a short half-life (∼5.5 h) and requires frequent dose administration when needed for longer period of time. In our current project, we designed pH responsive hydrogel blends of chondroitin sulfate/pluronic F-127 (CS/Pl) for the controlled release of ketorolac. METHODS: Hydrogel blends were fabricated using free radical polymerization reaction technique utilizing different ratios of chondroitin sulfate (CS) (polymer) and pluronic F-127 (polymer), acrylic acid (monomer), N,N'-methyl-bisacrylamide (MBA) (cross-linker), initiator ammonium persulfate (APS) and tween-80 (surfactant). The fabricated hydrogel blends were studied and evaluated for pH responsiveness, swelling, water absorbency, in vitro drug release, and morphological characteristics such as SEM, XRD, FTIR, and TGA/DSC. Acute toxicity study was performed on rabbits. RESULTS: Maximum swelling and water absorbency were shown by CS/Pl blends being significantly greater at 7.4 (basic pH) than in 1.2 (acidic pH). In vitro dissolution demonstrated pH responsive controlled KT release following zero order at higher pH (7.4) medium up to 36 h. FTIR studies confirmed the structures of our blends; SEM results showed porous framework; thermal studies revealed higher stability of hydrogels than the individual polymers; and XRD confirmed the nature of our blends. Toxicity study revealed the nontoxic nature of the hydrogel blends. CONCLUSION: The prepared CS/Pl hydrogels demonstrated stimuli-controlled release with delivery of drug for prolonged period of time and thus can minimize dosing frequency, safe drug delivery, increased patient compliance and easiness.

Anti-Inflammatory, analgesic and anti-pyretic activity of Fagonia bruguieri DC in rats.

Traditional medicine has employed the plant Fagonia bruguieri DC. to alleviate inflammation, fever and pain. The goal of this study was to test the anti-inflammatory, analgesic and antipyretic properties of the methanol extract of whole plant of Fagonia bruguieri (F. bruguieri). The writhing test and Eddy's hot plate test were used to assess the analgesic potential of F. bruguieri at three different doses. Carrageenan-induced rat paw edema was applied to investigate anti-inflammatory activity, whereas antipyretic activity was estimated in Brewer's yeast induced pyrexia model. Flavonoids, alkaloids, saponins, tannins and glycosides were found in F. bruguieri's phytochemical analysis. F. bruguieri at 750 mg/kg reduced writhing count by 62.23 percent, while F. bruguieri enhanced latency in Eddy's hot plate test. In carrageenan-induced edema, F. bruguieri at 750 mg/kg exhibited considerable anti-inflammatory effect (41.11 percent) after 2 nd, 3 rd and 4 th hours of therapy. F. bruguieri was also found to show antipyretic properties. The anti-inflammatory, analgesic and antipyretic properties of F. bruguieri were confirmed in this study, which might be attributable to the presence of several phyto-constituents.

Anti-asthmatic effect of Juglans regia Linn. in mice.

Plants are considered as an essential source to treat different diseases. In traditional system of medicine, Juglans regia (J. regia) has been used in curing sinusitis and cough. The aim of the present study was to evaluate the anti-asthmatic activity of J. regia in ovalbumin-induced allergic asthmatic BALB/c mice. The mice were sensitized intraperitoneally and subsequently challenged with ovalbumin (intranasal) to induce allergic asthma. Mice were treated with methanolic, n-hexane and ethyl acetate extracts of J. regia and methylprednisolone for 7 consecutive days, along with intranasal challenge. The total and differential leukocyte counts in blood, bronchoalveolar lavage fluid (balf) and lung wet/dry ratio were determined. GC-MS analysis was also performed. The results showed that ethyl acetate extract of J. regia significantly reduced inflammatory cells count in both blood and balf more significantly. Lung wet/dry weight ratio was reduced in asthmatic mice treated with the different extracts of J. regia. Serum IgE antibodies level was also significantly decreased in extracts treated groups. GC-MS analysis of all three extracts of J. regia showed the presence of various phytochemicals responsible for its anti-inflammatory and anti-asthmatic activity. The results of the present study validated the traditional use of J. regia in respiratory disorders like asthma and sinusitis.

Cardioprotective effect of boswellic acids against doxorubicin induced myocardial infarction in rats.

The aim of the present study was to evaluate the cardioprotective activity of boswellic acids in doxorubicin (DOX) induced cardiotoxicity. DOX (2.5mg/kg) was used intraperitoneally in rats to induce cardiotoxicity in six divided doses every alternate day over a period of two weeks. Dexrazoxane (10:1) was used as a standard drug. Boswellic acids (250, 500 and 750 mg/kg) were orally administered to rats for 14 days. After 14 days, rats were sacrificed, and blood was withdrawn through cardiac puncture. The blood lipid profile and cardiac biomarkers including LDH, CK-MB, CPK, SGOT and troponin T were measured. The heart of rats was isolated for histopathological studies. Graphpad Prism was used for statistical analysis. There was a significant increase in the level of cardiac enzymes and complete lipid profile parameters in diseased group as compared to control group. Pre-treatment with boswellic acids decreased level of all the measured parameters and decreased the severity of myocardial damage as supported by histopathological studies. It was concluded that boswellic acids possess cardioprotective potential by lowering cardiac biomarkers and blood lipid profile. Thus, boswellic acids might act as cardioprotective agent against doxorubicin induced cardiotoxicity.

Anti-oxidant and hepatoprotective effects of Lactuca serriola and its phytochemical screening by HPLC and FTIR analysis.

Lactucaserriola (L. serriola), commonly known asprickly lettuce, is an annual and biennial herb. The plant is traditionally used as sedative, hypnotic, cough suppressant, expectorant, purgative, diuretic, vasorelaxant, demulcent, antiseptic and antispasmodic. Aim of present study was to evaluate protective effect of L. serriola in paracetamol-induced hepatotoxicity. Silymarin was used as a standard drug. Hepatoprotective effect of extract was determined by liver biochemical markers, anti-oxidant enzymes and blood lipid profile. Methanolic extract was found to be the most potent in in-vitro antioxidant assays and used for further studies. Treatment with paracetamol increased the level of hepatic biomarkers, blood lipid profile and decreased anti-oxidant enzyme levels. Pre-treatment with Lactuca serriola caused restoration of hepatic biomarkers, blood lipid profile and antioxidant enzymes. FTIR represented that L. serriola contains hydroxyl (-OH), carboxylic acid (C=O) and alkene (C=C) groups. HPLC analysis showed presence of polyphenolic compounds in the methanolic extract of L. serriola. It is concluded that the methanolic extract of Lactuca serriola possesses hepatoprotective potential that might be linked to the presence of polyphenolic compounds and their anti-oxidant activities.

Hepatoprotective effect of Ziziphus oxyphylla Edgew in paracetamol-induced hepatotoxic rat model.

Ziziphus oxyphylla Edgew (Z. oxyphylla) is a small shrub to a medium sized tree. The aim of the present study was to evaluate the hepatoprotective activity of Z. oxyphylla in paracetamol-induced hepatotoxic rat model. Silymarin was used as a standard drug. Methanol extract was found to be the most potent in in-vitro antioxidant studies. The methanol extract of Z. oxyphylla was administered to experimental animals. The hepatoprotective effect of extract was evaluated by measuring liver biochemical markers, anti-oxidant enzymes and blood lipid profile. Treatment with the paracetamol increased the level of hepatic biomarkers, blood lipid profile and decreased anti-oxidant enzymes. Pre-treatment with Z. oxyphylla caused restoration of hepatic biomarkers, blood lipid profile and antioxidant enzymes levels. It is concluded that the methanol extract of Z. oxyphylla possesses hepatoprotective activity that might be due to quercetin and kaempferol glycosides present in the plant extract. Further studies are required to elucidate the exact mechanism of action of these isolated flavonoid glycosides.

Evaluation of Gastro-protective Activity of Myristica fragrans on Ethanol-induced Ulcer in Albino Rats.

Myristica fragrans seeds are traditionally used to treat dyspepsia, vomiting and abdominal pain. The purpose of this study was to investigate the protective effect of Myristica fragrans in ethanol induced gastric ulcer. Study was carried out on rats, divided into four groups; negative control, positive control, standard drug control, and Myristica fragrans extract treated rats. The pH, ulcer index, acidity values and histopathological examination of stomach were evaluated. Myristica fragrans significantly (P<0.05) reduced gastric lesions by 41.68% in ethanol induced ulcer model at 200 mg/kg when compared to sucralfate (60.41%). However, histopathological findings appeared similar in Myristica fragrans extract treated and standard drug control groups, where stomachs were found with mild erosion of superficial epithelium and few infiltrated inflammatory cells. pH of gastric contents of rats from extract treated was increased (4.25 ± 0.25) as compared to positive control group (2.25 ± 0.25). Ulcer index of extract treated rats was improved (41.74%). Moreover, total acidity of extract treated group (60.0 ± 0.47) was decreased as compared to control group (74.50 ± 1.04). It is concluded that Myristica fragrans showed significant protecting activity in ethanol induced ulcer. Isolation and purification of phytochemicals responsible for gastroprotective activity becomes necessary.

Self-nanoemulsifying drug delivery system for nebulization: fabrication and evaluation for systemic delivery of atorvastatin.

The study undertakes the development of an atorvastatin-loaded self-nanoemulsifying drug delivery system (SNEDDS) to improve its bioavailability. The SNEDDS were fabricated using oleic acid, Tween 80, and Span 80 by spontaneous emulsification. The SNEDDS were assessed for their particle size distribution, zeta potential, morphology, drug content, surface tension, viscosity, and drug release. The aerodynamic performance of the SNEDDS was evaluated using an Andersen cascade impactor, while the lipid-lowering potential of the SNEDDS was determined in Wistar rats using the analyzer "Microlab 300." The particle size of the SNEDDS ranged from 36 to 311 nm, with a polydispersity index (PDI) of 0.25-0.40. The zeta potential of the SNEDDS fluctuated from - 29.22 to - 38.26 mV, which declined to - 4.55 mV in the case of F5. The chitosan-coated formulation (F5) exhibited a higher viscosity (22.12 mPa s) and lower surface tension (0.056 dyne/cm) than other formulations (F1-F4). The non-coated formulation exhibited a significantly higher burst drug release, followed by a sustained drug release pattern (p ≤ 0.05) as compared to the coated formulation (F5). The nebulized SNEDDS achieved a dispersed fraction of 87 to 97%, where notably higher aerosol dispersion from F4 was attributed to its smaller particle size and circularity. The inhaled fraction of nebulized SNEDDS was 74-87%. The size of the SNEDDS droplets was the primary determinant affecting the aerodynamic performance of the SNEDDS during nebulization. The chitosan-coated SNEDDS achieved a higher antihyperlipidemic effect than marketed tablets, which shows the suitability of F5 for effective systemic delivery of atorvastatin through the lung.

Network pharmacology and molecular docking: combined computational approaches to explore the antihypertensive potential of Fabaceae species.

Hypertension is a major global public health issue, affecting quarter of adults worldwide. Numerous synthetic drugs are available for treating hypertension; however, they often come with a higher risk of side effects and long-term therapy. Modern formulations with active phytoconstituents are gaining popularity, addressing some of these issues. This study aims to discover novel antihypertensive compounds in Cassia fistula, Senna alexandrina, and Cassia occidentalis from family Fabaceae and understand their interaction mechanism with hypertension targeted genes, using network pharmacology and molecular docking. Total 414 compounds were identified; initial screening was conducted based on their pharmacokinetic and ADMET properties, with a particular emphasis on adherence to Lipinski's rules. 6 compounds, namely Germichrysone, Benzeneacetic acid, Flavan-3-ol, 5,7,3',4'-Tetrahydroxy-6, 8-dimethoxyflavon, Dihydrokaempferol, and Epiafzelechin, were identified as effective agents. Most of the compounds found non-toxic against various indicators with greater bioactivity score. 161 common targets were obtained against these compounds and hypertension followed by compound-target network construction and protein-protein interaction, which showed their role in diverse biological system. Top hub genes identified were TLR4, MMP9, MAPK14, AKT1, VEGFA and HSP90AA1 with their respective associates. Higher binding affinities was found with three compounds Dihydrokaempferol, Flavan-3-ol and Germichrysone, -7.1, -9.0 and -8.0 kcal/mol, respectively. The MD simulation results validate the structural flexibility of two complexes Flavan-MMP9 and Germich-TLR4 based on no. of hydrogen bonds, root mean square deviations and interaction energies. This study concluded that C. fistula (Dihydrokaempferol, Flavan-3-ol) and C. occidentalis (Germichrysone) have potential therapeutic active constituents to treat hypertension and in future novel drug formulation.

Application of green synthesized magnesium oxide nanoparticles to prolong commercial availability of Vitis vinifera L.

The objective of the study was to extend shelf life of Vitis vinifera (L.) by the application of green synthesized Magnesium oxide nanoparticles. Aqueous leaf extract of Azadirachta indica A. juss. and various concentrations of 20 mM, 30 mM, and 40 mM solutions of Magnesium nitrate hexa hydrate salt, were used to synthesize nanoparticles of different size. The characterization of nanoparticles was done by SEM, XRD, and UV. The antimicrobial activity of MgO NPs was evaluated for Azospirilum brasilense and Trichoderma viride, representative of microbes responsible for V. vinifera fruits spoilage. Nanoparticles with crystal size of 28.60 nm has more pronounced effect against microbes. The Shelf life of the Vitis vinifera L. was evaluated by application of 28.60 nm MgO NPs through T1 (nanoparticles coated on packaging), T2 (nanoparticles coated directly on fruit) at 4 °C and 25 °C. T1 at 4 °C was effective to extend the shelf life of Vitis vinifera (L) for an average of 20 days.

Exploring the hepatoprotective properties of citronellol: In vitro and in silico studies on ethanol-induced damage in HepG2 cells.

Citronellol (CT) is a monoterpene alcohol present in the essential oil of plants of the genus Cymbopogon and exhibits diverse pharmacological activities. The aim of the current study was to investigate the hepatoprotective potential of CT against ethanol-induced toxicity in HepG2 cell lines. Silymarin (SIL) was used as a standard drug. MTT, crystal violet assay, DAPI, and PI staining were carried out to assess the effect of ethanol and CT on cell viability. RT-PCR determined the molecular mechanisms of hepatoprotective action of CT. CT ameliorated cell viability and restricted ethanol-induced cell death. DAPI and PI staining showed distinct differences in cell number and morphology. Less cell viability was observed in the diseased group obviously from strong PI staining when compared to the CT- and SIL-treated group. Moreover, CT showed downregulation of interleukin (IL-6), transforming growth factor-beta 1 (TGF-ß1), collagen type 1 A 1 (COL1A1), matrix metalloproteinase-1 (MMP-1), tissue inhibitor of metalloproteinase-1 (TIMP-1) and glutathione peroxidase-7 (GPX-7) levels. Molecular docking studies supported the biochemical findings. It is concluded that the cytoprotective activity of CT against ethanol-induced toxicity might be explained by its anti-inflammatory, immunomodulatory, and collagen-regulating effects.

Fenchone, a monoterpene: Toxicity and diuretic profiling in rats.

Fenchone is a monoterpene present in the essential oils of various plants, including Foeniculum vulgare and Peumus boldus. Previous studies confirmed the anti-inflammatory, antioxidant, wound-healing, antidiarrheal, antifungal, antinociceptive, and bronchodilator activities of fenchone. Owing to various pharmacological activities of Fenchone, the current research was designed to evaluate its diuretic activity along with toxicity profiling. For evaluating acute toxicity, OECD guideline 425 was followed in which a single dose of 2000 mg/kg was orally administered to rats. For evaluating the diuretic potential in rats, three doses of Fenchone (100, 200, and 400 mg/kg) were assayed in comparison to furosemide (15 mg/kg) as the standard drug, followed by measurements of urinary volume, urinary electrolytes, uric acid, and urinary creatinine in saline-loaded rats for 8 h. The acute toxicity study showed a significant increase in hemoglobin (Hb), red blood cells (RBCs), alkaline phosphatase (ALP), and alkaline transaminase (ALT) along with a significant decrease in serum triglycerides, cholesterol, and uric acid levels when compared with the control group. The oxidative stress parameter, superoxide dismutase (SOD), was increased in the heart and spleen. Nitrite (NO) and glutathione were significantly increased in the kidney. The acute diuretic effect of Fenchone (400 mg/kg) significantly increased the urinary output, electrolytes (Na+, K+, and Ca++), urinary creatinine, and urinary uric acid in a dose-dependent manner. The Na+/K+ ratio was remarkably higher in the treatment group than that of the control group. The diuretic index, saluretic index, and Lipschitz value were also calculated from electrolyte concentration and urinary volume measurements, and the values were significantly increased in rats administered with fenchone at 400 mg/kg dose. The current study concluded that fenchone is safe and has remarkable diuretic action.

Determination of the roles of cADPR and NAADP as intracellular calcium mobilizing messengers in S1P-induced contractions in rat bladders having IC/PBS.

AIMS: Interstitial cystitis/painful bladder syndrome (IC/PBS) is characterized by lower abdominal pain and increased frequency and urgency of urine. Sphingosine 1-phosphate (S1P) is a bioactive sphingolipid that plays role in calcium homeostasis in smooth muscle. The intracellular calcium mobilizing secondary messengers are also involved in smooth muscle contraction. The role of intracellular calcium storing depots in S1P-induced contraction was investigated in permeabilized detrusor smooth muscle having cystitis. MAIN METHODS: IC/PBS was induced by cyclophosphamide injection. The detrusor smooth muscle strips isolated from rats were permeabilized with ß-escin. KEY FINDINGS: S1P-induced contraction was increased in cystitis. S1P-induced enhanced contraction was inhibited by cyclopiazonic acid, ryanodine and heparin showing involvement of sarcoplasmic reticulum (SR) calcium stores. Inhibition of S1P-induced contraction by bafilomycin and NAADP suggested the participation of lysosome-related organelles. SIGNIFICANCE: IC/PBS triggers S1P-induced increase in intracellular calcium from SR and lysosome-related organelles in permeabilized detrusor smooth muscle.

Caftaric Acid Ameliorates Oxidative Stress, Inflammation, and Bladder Overactivity in Rats Having Interstitial Cystitis: An In Silico Study.

Interstitial cystitis (IC) is the principal unwanted effect associated with the use of cyclophosphamide (CYP). It results in increased oxidative stress, overexpression of proinflammatory cytokines, and bladder overactivity. Patients receiving CYP treatment had severely depreciated quality of life, as the treatment available is not safe and effective. The goal of this study was to assess the protective effect of caftaric acid in CYP-induced IC. IC was induced in female Sprague Dawley by injecting CYP (150 mg/kg, i.p.). In the present study, oral administration of caftaric acid (20, 40, and 60 mg/kg) significantly decreased inflammation. Caftaric acid significantly increased SOD (93%), CAT (92%), and GSH (90%) while decreased iNOS (97%), IL-6 (90%), TGF 1-ß (83%), and TNF-α (96%) compared to the diseased. DPPH assay showed the antioxidant capacity comparable to ascorbic acid. Molecular docking of caftaric acid with selected protein targets further confirmed its antioxidant and anti-inflammatory activities. The cyclophosphamide-induced bladder overactivity had been decreased possibly through the inhibition of M3 receptors, ATP-sensitive potassium channels, calcium channels, and COX enzyme by caftaric acid. Therefore, our findings demonstrate that caftaric acid has a considerable protective role against CYP-induced IC by decreasing the oxidative stress, inflammation, and bladder smooth muscle hyperexcitability. Thus, caftaric acid signifies a likely adjuvant agent in CYP-based chemotherapy treatments.
