RESUMO

The anti-diabetic effect of Ficus carica (Fig) seed oil was investigated. 4 groups with 6 rats in each group were used in the experiment as control, diabetes (45 mg/kg streptozotocin), fig seed oil (FSO) (6 mL/ kg/day/rat by gavage) and diabetes+FSO groups. Glucose, urea, creatinine, ALT, AST, GSH, AOPP and MDA analyses were done. Pancreatic tissues were examined histopathologically. When fig seed oil was given to the diabetic group, the blood glucose level decreased. In the diabetes+FSO group, serum urea, creatinine, AOPP, MDA levels and ALT and AST activities decreased statistically significantly compared to the diabetes group, while GSH levels increased significantly, histopathological, immunohistochemical, and immunofluorescent improvements were observed. It has been shown for the first time that FSO has positive effects on blood glucose level and pancreatic health. It can be said that the protective effect of fig seed oil on tissues may be due to its antioxidant activity.

RESUMO

Figs are the edible fruits of the fig tree, Ficus carica L., that have been used for centuries for human consumption and in traditional medicine, to treat skin problems, inflammation, and gastrointestinal disorders. Our previous study investigated the presence of phenolic compounds in aqueous extracts of two Algerian popular fig varieties, azendjar (Az) and taamriouth (Ta), as well as their in vitro antioxidant activity. In this study, we assessed hydroethanolic extracts of these fig varieties. The total phenolic content was measured, along with the phenolic profile. Rutin was determined to be the dominant phenolic compound, followed by vanillic acid, 3,4-dihydroxybenzoic acid, quercetin, 4-hydroxybenzoic acid, rosmarinic acid (in Az only), and cinnamic acid. The antioxidant activity of the extracts was evaluated both in vitro (DPPH and FRAP assays) and in vivo, in rats intoxicated with carbon tetrachloride. In all assays, the fig extract-especially the dark-peeled fig variety azendjar-showed antioxidant potency. The administration of fig extract resulted in a reduction in liver damage, expressed by both different biochemical markers and histopathological study (less degraded liver architecture, reduced fibrosis, and only mild inflammation). A dose-dependent therapeutic effect was observed. The extract from the dark-peeled fig variety, Az, was characterized by a higher phenolic content and a stronger antioxidant activity than the extract from the light-peeled variety-Ta. Our study justifies the use of figs in traditional healing and shows the potential of using fig extracts in natural medicines and functional foods.

RESUMO

The majority of Iranian fig production is exported, making it one of the world's most well-known healthy crops. Therefore, the main objective of the current experiment was to investigate the effects of various types of organic fertilizers, such as animal manure (cow and sheep), bird manure (partridge, turkey, quail, and chicken), and vermicompost, on the nutritional status of trees, vegetative and reproductive tree characteristics, fruit yield, and fruit quality traits in dried fig cultivar ("Sabz"). According to the findings, applying organic fertilizers, particularly turkey and quail, significantly improves vegetative and reproductive characteristics. However, other manures such as sheep, chicken, and vermicompost had a similar effect on the growth parameters of fig trees. Additionally, the findings indicated that except for potassium, use of all organic fertilizers had an impact on macro and microelements such as phosphorus, nitrogen, and sodium amount in fig tree leaves. Also, based on fruit color analysis in dried figs, the use of all organic fertilizers improved fruit color. Moreover, the analyses fruit biochemical showed that the use of some organic fertilizers improved that TSS and polyphenol compounds such as coumarin, vanillin, hesperidin gallic acid and trans frolic acid. In general, the results indicated that the addition of organic fertilizers, especially turkey manure, led to increased vegetative productivity and improvement in the fruit quality of the rain-fed fig orchard.

RESUMO

Dried figs were studied by Electron Paramagnetic Resonance (EPR) spectroscopy for identification of radiation treatment and dosage assessment. Gamma-irradiated samples show a multicomponent "sugar-like" EPR spectrum with line width of 6-8 mT, centered at g = 2.004. The investigation of the influence of the instrumental parameters microwave power and modulation amplitude on the EPR signal show saturation effect at microwave power above 2 mW and over modulation at modulation amplitude above 0.4 mT. Determination of the stability of radiation induced signals shows, that identification of previous radiation treatment is possible for a long time period after irradiation even more than one year. Dose-response curves of gamma-irradiated samples exhibits a linear response up to about 4 kGy and the saturation of the EPR signal at higher doses. A Single Aliquot Additive dosing method used to estimate the initial absorbed dose in irradiated dried fig flesh shows initial dose 0.25 kGy for the sample irradiated by 5 kGy and 3.7 kGy for those irradiated using 10 kGy. Taking into account the signal decay after 150 days of storage, the dose defined as initial should be 4.65 kGy for the 5 kGy irradiated sample and 8 kGy for that irradiated using 10 kGy.

RESUMO

Ficus drupacea is a medicinal tree found in temperate regions. Various parts of this plant had been used traditionally for the treatment of various ailments such as root powder applied externally for skin infections. Analysis was carried out on the bioactive lipids extracted from Ficus drupacea fruit using both petroleum-based solvent (Hexane) and an environmentally friendly solvent Dimethyl carbonate (DMC). The results showed that DMC extraction yielded a high oil content in Ficus drupacea fruit (6.51 %). When examining the fatty acid composition using GC-FID analysis, Ficus drupacea oil extracted with DMC contained significant proportions of essential fatty acids such as linoleic acid (32.317 %), oleic acid (20.946 %), palmitic acid (25.841 %), etc. Additionally, DMC extraction resulted in higher levels of total phenolics in Ficus drupacea fruit oil compared to hexane. Moreover, DMC extracted oil exhibited stronger antioxidant properties, such as radical scavenging, anti- arthritic, photoprotective activity while displayed similar anti-inflammatory and anti-microbial activity as hexane-extracted oil. In summary, these findings demonstrate that DMC is an efficient and safer alternative to conventional solvent hexane for extracting oils from Ficus drupacea fruit. It is rich in bioactive compounds essential for human nutrition, including polyunsaturated fatty acids, flavonoids, and phenolic compounds, with enhanced biological activities.

RESUMO

Neurodegenerative diseases (NDs) are a significant global health concern, primarily affecting middle and older populations. Recently, there has been growing interest in herbal therapeutics as a potential approach to address diverse neuropathological conditions. Despite the widespread prevalence of NDs, limited phytochemical has been reported for their promising therapeutic potential with distinct underlying mechanisms. Additionally, the intricate molecular pathways influenced by herbal phytoconstituents, particularly in neurodegenerative disorders, are also not well documented. This report explores the phytoconstituents of Ficus racemosa (F. racemosa), an unfamiliar plant of the Moraceae family, for their potential interactions with pathological pathways of NDs. The influential phytoconstituents of F. racemosa, including polyphenols, glycosides, terpenoids, and furocoumarin, have been reported for targeting diverse pathological states. We proposed the most convincing molecular interplay between leading phytoconstituents and detrimental signalling cascades. However, extensive research is required to thoroughly understand the phytochemical persuaded intricate molecular pathway. The comprehensive evidence strongly suggests that F. racemosa and its natural compounds could be valuable in treating NDs. This points towards an exciting path for future research and the development of potential treatments based on a molecular level.

RESUMO

Four undescribed coumarin derivatives, ficusalt A (1) and ficusalt B (2), a pair of racemic coumarins, (±) ficudimer A (3a/3b), along with ten known amides, were isolated from the roots of Ficus hirta. Their structures were elucidated by several spectroscopic data analyses, including HRESIMS, NMR, and X-ray single-crystal diffraction. The cytotoxic activities of all compounds against HeLa, HepG2, MCF-7, and H460 cell lines were detected using the MTT assay. Among these, 5 showed the highest activity against HeLa cells. Subsequently, the apoptotic, anti-invasive, and anti-migration effects of 5 on HeLa cells were determined by flow cytometer, transwell invasion assay, and wound-healing assay, respectively. The result suggested that 5 distinctly induced the apoptosis in HeLa cells and inhibited their invasion and migration. Further studies on anticancer mechanisms were conducted using Western blotting. As a result, 5 increased the cleavage of PARP and the expression of pro-apoptotic protein Bax. Moreover, 5 notably upregulated the phosphorylation of p38 and JNK, whereas inhibited the expression of p-ERK and p-AKT. Our results demonstrated that 5 could be a potential leading compound for further application in the treatment of cervical cancer.

RESUMO

Ficus deltoidea was known for its potent antioxidant, anti-melanogenic and photoprotective skin barrier activities. These properties are contributed by its biomarkers which are vitexin and isovitexin. This study aims to optimize the yield of methanolic extraction of Ficus deltoidea leaves (EFD) and evaluate their effects on skin barrier function and hydration. For optimization, Box-Behnken design was utilized to investigate the effects of methanol concentration, sonication time, and solvent-to-sample ratio on the yields of vitexin and isovitexin in EFD. The optimal yields obtained were 32.29 mg/g for vitexin and 35.87 mg/g for isovitexin. The optimum extraction conditions were 77.66% methanol concentration, 20.03 min sonication time, and 19.88 mL/g solvent-to-sample ratio. The quantitative real-time polymerase chain reaction was utilized to measure variant marker genes of transglutaminase-1, caspase 14, ceramide synthase 3, involucrin, and filaggrin of EFD-induced keratinocyte differentiation by in vitro study. Exposure to EFD has elevated the mRNA levels of all tested marker genes by 0.7-9.2 folds. Then, in vivo efficacy study was conducted on 20 female subjects for 14 days to evaluate skin biophysical assessment of hydration. EFD topical formulation treatment successfully increased skin hydration on day 7 (43.74%) and day 14 (47.23%). In silico study by molecular docking was performed to identify intermolecular binding interactions of vitexin and isovitexin with the interested proteins of tested marker genes. The result of molecular docking to the interested proteins revealed a similar trend with real-time PCR data. In conclusion, EFD potentially enhanced the skin barrier function and hydration of human skin cells.

RESUMO

BACKGROUND: Fig (Ficus carica L.) fruit is consumed worldwide as a functional food. It contains phytochemicals that have been related to health benefits. However, the characteristic chemicals remain unclear. In this work, phytochemicals were prepared from figus by ultrasound-assisted extraction under optimized conditions. The chemical composition of fig fruit and leaves was characterized by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). RESULTS: One hundred and fifty-seven compounds were identified, including 58 flavonoids, 29 coumarins, 19 acids, 15 terpenoids, 11 alkaloids, and 25 other compounds. The mass spectrum (MS) fragmentation pathways of representative chemicals were elucidated. Flavonoid glycosides and prenylated flavonoids were mainly present in fig fruit, whereas coumarins were abundant in leaves. Both fig fruit and leaf extracts showed good cellular antioxidant activity. CONCLUSION: The full phytochemical profile of fig was revealed by UPLC-MS/MS. Prenylated flavonoids and prenylated coumarins were the characteristic phytochemicals. These data provided useful information for the extensive utilization of fig fruit in functional food. © 2023 Society of Chemical Industry.

RESUMO

In this research, the ultrasound-assisted extraction (UAE) conditions of the water-soluble polysaccharide (FCPS) from Ficus carica fruits were optimized using the response surface methodology. The optimal FCPS yield was 7.97 % achieved by conducting ultrasound-assisted extraction four times at a solid-liquid ratio of 1:20 (g/mL) and an ultrasound temperature of 70 °C. Then, the structure, antioxidant properties, hypoglycemic effects, and immunomodulatory activities of FCPS were evaluated. FCPS was characterized as irregular, rough-surfaced, flaky materials consisting of pyran-type polysaccharides with α- and ß-glycosidic linkages, and composed of multiple monosaccharides and only one homogeneous concentrated polysaccharide component (FCPS1) with a molecular weight of 4.224 × 104 Da. The results suggested FCPS exhibited remarkable antioxidant activity in vitro, as evidenced by improved cell viability and reduced the reactive oxygen species (ROS) levels. Meanwhile, FCPS effectively improved liver-related insulin resistance by promoting glucose consumption in hepatocytes and activated the immune response through activation of murine bone marrow-derived dendritic cells (DCs) and upregulation of interleukin 6 (IL6) and interleukin 12 (IL-12) expression. The findings demonstrate the efficacy of the UAE technique in isolating FCPS with biological functionality and FCPS could potentially serve as a beneficial organic antioxidant source and functional food, carrying important implications for future studies.

RESUMO

The burden of metabolic disorders is alarmingly increasing globally. On the other hand, sustainability is the key project of the 21st century. Natural products offer a coherent option for the complementary management of both these challenges. Ficus carica (FC), commonly known as the fig fruit, has an experimentally proven potency for the modulation of cell cycle, immunity, inflammation, metabolism, and oxidative stress. Here, we review the potential of FC-derived products (FCDP) in slowing down the progression of cancers, acute/chronic inflammation-related conditions, infections, metabolic disorders, toxicities, neurological and neuromuscular diseases, gastrointestinal disorders, vascular diseases, and skin-stressing conditions, as well as, in boosting normal healthy functions of the endocrine, immune, metabolic, and nervous systems. It reveals a variety of cellular and molecular targets for FCDP: cytokines (TNF-α, IL-1ß, IL-6, IL-10, IL-12, IL-18, IFN-γ), chemokines (CCL2), other inflammatory mediators (CRP, PGE2), immune receptors (TLR-2, TLR-4, FcεRI), oxidative stress-related markers (SOD, GSH, MDA, GPx, catalase, ROS, NO, protein carbonyls), kinases (MAPKs, hexokinase, G6Pase, FBPase, PEPCK, Akt, AMPK, GSK3, CDKs), other enzymes (COX-2, iNOS, MMPs, caspases), growth factors/receptors (VEGF, EGFR), hormones (DHEAS, prolactin, GnRH, FSH, LH, estradiol, DHT, insulin), cell death-related markers (Bcl-2, Bax, Bak, FasL, gasdermins, cytochrome C), glucose transporter protein (Glut4), and transcription factors (NF-κB, HNF-4α, Foxo, PGC-1α, PPAR-γ, C/EBP-α, CREB, NFATC1, STAT3). FCDP cause both activation and inhibition of AMPK, MAPK, and NF-κB signaling to confer condition-specific advantages. Such a broad-range activity might be attributed to different mechanisms of action of FCDP in modulating functions within the classical immunometabolic system, but also beyond.

RESUMO

Ficus religiosa L., a member of the Moraceae family, is a medicinal plant having a number of pharmacological properties. The anti-inflammatory and analgesic actions of an ethanolic extract of F. religiosa bark FRE (at 100 and 200mg/kg dosages) and the biomarker component quercetin QC (at 5 and 10mg/kg doses) were investigated. The estimate of quercetin was carried by using an HPTLC analysis of FRE. Additionally, qualitative and quantitative screening for key important phytocomponents was done using dried, ground plant stem barks. By using molecular docking, the molecular interaction profile with several anti-inflammatory drug targets was examined. Both the FRE as well as QC showed a substantial decline in paw volume when compared with the relevant control groups (p<0.01 & p<0.001). Following the administration of acetic acid to mice, the FRE and QC both demonstrate a substantial lengthening of the paw licking or leaping towards Eddy's hot plate as well as a decrease in the number of writhes (p<0.01 & p<0.001). This study supports the use of these herbs in conventional medicine to treat pain and inflammation by through similar mechanism as compound quercetin (QC).

RESUMO

Cervical carcinogenesis is the leading cause of cancer-related deaths in women, and the role of high-risk human papillomavirus (HR-HPV) as a possible risk factor in the development of this cancer is well recognized. Despite the availability of multi-therapeutic approaches, there is still major concern regarding the prevention of metastatic dissemination and excessive tissue injuries. Therefore, it is imperative to develop a safer and more efficient treatment modality. Ficus carica, a natural plant, has shown potential therapeutic properties through its fruit latex when applied to HPV-positive cervical cancer cell lines. However, the mechanisms of action of Ficus carica (fig) latex are not well understood. This study aims to provide a deeper insight into the biological activities of fig latex on human cervical cancer cell lines expressing high-risk HPV types 16 and 18. The data obtained from this study reveal that fig latex influences the expression of genes involved in "Class I MHC-mediated antigen presentation" as well as "Antigen processing: Ubiquitination and Proteasome degradation". These genes play a crucial role in host immune surveillance and the resolution of infection. Notably, Western blot analysis corroborated these findings, demonstrating an increase in the expression of MHC class I in HeLa cells after fig latex treatment. Findings from this study suggest that fig latex may enhance T cell responses against oncogenic HPV, which could be beneficial for the clearance of early-stage cancer.

RESUMO

Binders are ingredients used in tablet granulation process for tablet cohesiveness which confirms that the tablet remains intact after compression. Natural gums have been employed as disintegrants, emulsifying agents, suspending agents, and binders in tablets. Even though Ficus vasta gum is claimed as a possible pharmaceutical excipient by some phytochemical studies, literature is scanty on its efficacy as a tablet binder. The purpose of this study was to isolate, characterize, and comparatively evaluate Ficus vasta gum as a potential binder in tablet formulation. Gum was extracted from Ficus vasta tree, characterized for physicochemical properties, and applied as a binder in paracetamol granule and tablet formulation. Granules were prepared using 4%, 6%, 8%, and 10% w/w concentration of the gum and standard binders (polyvinylpyrrolidone K-30 and Starch@1500) by wet granulation. The formulated tablets were then evaluated for tablet quality parameters, and comparison between the test and standard binders was done by ANOVA. The dried crude gum yielded 50.63% (w/w) of a brownish yellow purified gum. The angle of repose, Carr's index, and the Hausner ratio all complied with the pharmacopoeial recommendations. The gum is compatible with the model drug, paracetamol. The paracetamol granules prepared with Ficus gum binder demonstrated an optimum size range and size distribution with substantial flow and compressibility properties. Ficus gum binder demonstrated significantly higher disintegration time and strength properties than that of similar concentrations of Starch@1500 but lower than polyvinylpyrrolidone (p < 0.05). Ficus gum has better binding properties than starch but lower than polyvinylpyrrolidone. Hence, Ficus vasta gum can be used as an alternative tablet binder in tablet manufacturing.

RESUMO

PURPOSE: The O-(2-[18F]-fluoroethyl)-L-tyrosine (FET) PET in Glioblastoma (FIG) trial is an Australian prospective, multi-centre study evaluating FET PET for glioblastoma patient management. FET PET imaging timepoints are pre-chemoradiotherapy (FET1), 1-month post-chemoradiotherapy (FET2), and at suspected progression (FET3). Before participant recruitment, site nuclear medicine physicians (NMPs) underwent credentialing of FET PET delineation and image interpretation. METHODS: Sites were required to complete contouring and dynamic analysis by ≥ 2 NMPs on benchmarking cases (n = 6) assessing biological tumour volume (BTV) delineation (3 × FET1) and image interpretation (3 × FET3). Data was reviewed by experts and violations noted. BTV definition includes tumour-to-background ratio (TBR) threshold of 1.6 with crescent-shaped background contour in the contralateral normal brain. Recurrence/pseudoprogression interpretation (FET3) required assessment of maximum TBR (TBRmax), dynamic analysis (time activity curve [TAC] type, time to peak), and qualitative assessment. Intraclass correlation coefficient (ICC) assessed volume agreement, coefficient of variation (CoV) compared maximum/mean TBR (TBRmax/TBRmean) across cases, and pairwise analysis assessed spatial (Dice similarity coefficient [DSC]) and boundary agreement (Hausdorff distance [HD], mean absolute surface distance [MASD]). RESULTS: Data was accrued from 21 NMPs (10 centres, n ≥ 2 each) and 20 underwent review. The initial pass rate was 93/119 (78.2%) and 27/30 requested resubmissions were completed. Violations were found in 25/72 (34.7%; 13/12 minor/major) of FET1 and 22/74 (29.7%; 14/8 minor/major) of FET3 reports. The primary reasons for resubmission were as follows: BTV over-contour (15/30, 50.0%), background placement (8/30, 26.7%), TAC classification (9/30, 30.0%), and image interpretation (7/30, 23.3%). CoV median and range for BTV, TBRmax, and TBRmean were 21.53% (12.00-30.10%), 5.89% (5.01-6.68%), and 5.01% (3.37-6.34%), respectively. BTV agreement was moderate to excellent (ICC = 0.82; 95% CI, 0.63-0.97) with good spatial (DSC = 0.84 ± 0.09) and boundary (HD = 15.78 ± 8.30 mm; MASD = 1.47 ± 1.36 mm) agreement. CONCLUSION: The FIG study credentialing program has increased expertise across study sites. TBRmax and TBRmean were robust, with considerable variability in BTV delineation and image interpretation observed.

RESUMO

This study compared the phenolic composition and antioxidant properties of three varieties of fig fruits (Ficus carica L) from the Eastern Black Sea region of Türkiye. Total polyphenol content (TPC), total flavonoid content (TFC), and phenolic compositions were analyzed in green, purple, and dark purple species. The mean TPC value was 42.10 ± 5.71 mg GAE/100 g FW, ranging from 35.98 to 47.30 mg GAE/100 g FW, and was highest in the dark purple species. The mean TFC value was 1.27 ± 0.93 mg QUE/100 FW g, ranging between 0.35 and 2.21 mg QUE/100 FW g, and was highest in the purple species. The samples' total antioxidant capacity was measured based on ferric reducing/antioxidant power (FRAP), the values ranging from 151.98 to 372.97 µmol FeSO4.7H2O/100 g FW, with an average value of 239.64 µmol FeSO4.7H2O/100 g FW, being highest in the dark purple species. The 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of the fruits was expressed as SC50 (mg/mL), and the values ranged from 10.04 to 42.42 mg/mL, being highest in the purple species. The phenolic composition was analyzed using HPLC-PDA according to the method in which 25 phenolic standards were used. Chlorogenic acid and t-cinnamic acid were the most common phenolic compounds, with rutin, chrysin, apigenin, and luteolin being detected at different amounts. In conclusion, the purple species contained the highest flavonoid content, was rich in apigenin, luteolin, and chrysin, and possessed the highest DPPH radical scavenging activity.

RESUMO

INTRODUCTION: Glioblastoma is the most common aggressive primary central nervous system cancer in adults characterised by uniformly poor survival. Despite maximal safe resection and postoperative radiotherapy with concurrent and adjuvant temozolomide-based chemotherapy, tumours inevitably recur. Imaging with O-(2-[18F]-fluoroethyl)-L-tyrosine (FET) positron emission tomography (PET) has the potential to impact adjuvant radiotherapy (RT) planning, distinguish between treatment-induced pseudoprogression versus tumour progression as well as prognostication. METHODS AND ANALYSIS: The FET-PET in Glioblastoma (FIG) study is a prospective, multicentre, non-randomised, phase II study across 10 Australian sites and will enrol up to 210 adults aged ≥18 years with newly diagnosed glioblastoma. FET-PET will be performed at up to three time points: (1) following initial surgery and prior to commencement of chemoradiation (FET-PET1); (2) 4 weeks following concurrent chemoradiation (FET-PET2); and (3) within 14 days of suspected clinical and/or radiological progression on MRI (performed at the time of clinical suspicion of tumour recurrence) (FET-PET3). The co-primary outcomes are: (1) to investigate how FET-PET versus standard MRI impacts RT volume delineation and (2) to determine the accuracy and management impact of FET-PET in distinguishing pseudoprogression from true tumour progression. The secondary outcomes are: (1) to investigate the relationships between FET-PET parameters (including dynamic uptake, tumour to background ratio, metabolic tumour volume) and progression-free survival and overall survival; (2) to assess the change in blood and tissue biomarkers determined by serum assay when comparing FET-PET data acquired prior to chemoradiation with other prognostic markers, looking at the relationships of FET-PET versus MRI-determined site/s of progressive disease post chemotherapy treatment with MRI and FET-PET imaging; and (3) to estimate the health economic impact of incorporating FET-PET into glioblastoma management and in the assessment of post-treatment pseudoprogression or recurrence/true progression. Exploratory outcomes include the correlation of multimodal imaging, blood and tumour biomarker analyses with patterns of failure and survival. ETHICS AND DISSEMINATION: The study protocol V.2.0 dated 20 November 2020 has been approved by a lead Human Research Ethics Committee (Austin Health, Victoria). Other clinical sites will provide oversight through local governance processes, including obtaining informed consent from suitable participants. The study will be conducted in accordance with the principles of the Declaration of Helsinki and Good Clinical Practice. Results of the FIG study (TROG 18.06) will be disseminated via relevant scientific and consumer forums and peer-reviewed publications. TRIAL REGISTRATION NUMBER: ANZCTR ACTRN12619001735145.

RESUMO

Coccidiosis is an acute gastrointestinal parasitic disease and causes approximately $2.80 to $3.27 per m2 loss in a broiler farm of a 33-day-old flock. In this study, iron oxide nanoparticles (IONPs) were green synthesized using the aqueous leaf extract of Ficus racemosa as a reducing and capping agent to reduce the emerging resistance in coccidia spores against conventional treatments and boost the immune level in broilers. These IONPs were evaluated for their impacts on the growth performance, biochemistry, blood profile, and histology in the coccidiodized broiler chicken with Emeria tenella under in vivo conditions. The characteristics and stability of particles were obtained using UV-Vis spectroscopy, Fourier transforms infrared (FTIR), X-Ray diffraction (XRD), energy dispersive X-ray absorption (EDX), scanning electron microscopy (SEM), zeta potential and zeta size. The results indicated that IONPs at the moderate dose of 15 mg/kg (p = 0.001) reduced the coccidial impacts by eliminating oocyst shedding per gram feces (up to 91%) and reducing clinical symptoms (lesions (LS = 0), bloody diarrhea (No), and mortality (0%) in chicken at day 10 of treatment as compared to the negative control group-B (infected & non-treated). A dose-dependent and time-dependent trend were observed during treatments (10, 15, and 20 mg/kg) of 1-3 weeks using IONPs against the coccidial impacts on the growth parameters (body weight gain, mean feed consumption, feed conversion ratio) and biochemistry (plasma glucose, total protein, uric acid, ALT, AST, and ALP) in chickens. Additionally, F. racemosa IONPs at a dose of 15 and 20 mg/kg significantly recovered the parasitized and highly damaged hepatocytes, liver tissues, and ceca tissues after 1-3 weeks of treatment in broiler chickens. Overall, the 15 mg/kg concentration of IONPs exhibited fast recovery and growth enhancement in coccidiodized broilers. Therefore, the 15 mg/kg dose of green synthesized IONPs using leaf extract of F. racemosa could be a potential and safe anticoccidial agent with targeted implications in the poultry industry.

RESUMO

Ficucaricone D (1) and its 4'-demethyl congener 2 are isoflavones isolated from fruits of Ficus carica that share a 5,7-dimethoxy-6-prenyl-substituted A-ring. Both natural products were, for the first time, obtained by chemical synthesis in six steps, starting from 2,4,6-trihydroxyacetophenone. Key steps are a microwave-promoted tandem sequence of Claisen- and Cope-rearrangements to install the 6-prenyl substituent and a Suzuki-Miyaura cross coupling for installing the B-ring. By using various boronic acids, non-natural analogues become conveniently available. All compounds were tested for cytotoxicity against drug-sensitive and drug-resistant human leukemia cell lines, but were found to be inactive. The compounds were also tested for antimicrobial activities against a panel of eight Gram-negative and two Gram-positive bacterial strains. Addition of the efflux pump inhibitor phenylalanine-arginine-ß-naphthylamide (PAßN) significantly improved the antibiotic activity in most cases, with MIC values as low as 2.5 µM and activity improvement factors as high as 128-fold.

RESUMO

Inflammation is an innate reaction of the body of an individual when subjected to the noxious factors repeatedly. Pharmacological approaches focused at disrupting cytokine signaling networks have become significant therapeutic alternatives for the treatment of inflammatory illnesses, cancer and autoimmune disorders. High levels of inflammatory mediators, particularly interleukin IL-1, IL-6, IL-18, IL-12, and tumor necrosis factor alpha leads to a cytokine storm in the body. Among all the released cytokines in a patient suffering from inflammatory disorder, IL-6 mediator has a pivotal role in this inflammatory cascade which progresses to a cytokine storm. Therefore, the blockage of the IL-6 inflammatory mediator could be a promising treatment option for the patients with hyper inflammatory conditions. The phytochemicals could provide the new lead compounds against the IL-6 mediator. Ficus carica has been the ideal plant of research and investigation due to its commercial, economic and medical importance. The anti-inflammatory properties of F. carica were further investigated by in silico and in vivo approaches. The docking scores of Cyanidin-3,5-diglucoside, Kaempferol-7-O-rutinoside, Cyanidin-3-rhamnoglucoside, and Rutin are -9.231, -8.921, -8.840, and -8.335 Kcal/mole respectively. The free energy of binding and stability of the docked complexes of these top four phytochemicals with the IL-6 were further analyzed by Molecular Mechanics-Generalized Born Surface Area and Molecular Dynamic simulations, respectively. The in vivo anti-inflammatory carrageenan-induced rat paw edema model was used for the validation of in silico results. The maximum percentage paw edema inhibition with petroleum ether and ethyl acetate was 70.32% and 45.05%, respectively. The in vivo anti-inflammatory activity confirms the anti-inflammatory potential of F. carica. Therefore, it is predicted that Cyanidin-3,5-diglucoside, Kaempferol-7-O-rutinoside, Cyanidin-3-rhamnoglucoside, and Rutin have the potential to inhibit the IL-6 mediator which will aid in mitigating the cytokine storm in patients with acute inflammations.
