RESUMO

The present research demonstrates the formation of zinc oxide nanoparticles facilitated by Cissus quadrangularis (CQ-ZnONPs) and subsequent synthesis of chitosan-conjugated nanocomposites (CQ-CS/ZnONCs) along with their biological assessment. The biosynthesized nanoparticles and nanocomposites were physicochemically characterized and therapeutically assessed for their antioxidant, antibacterial, and antidiabetic potential. The formation of CQ-ZnONPs and CQ-CS/ZnONCs was preliminarily validated by the change in color and subsequently by UV-visible spectroscopic analysis. The crystalline peaks associated with the CQ-ZnONPs in CQ-CS/ZnONCs were established by XRD analysis. Morphological evaluation of CQ-ZnONPs and CQ-CS/ZnONCs was carried out through FE-SEM and HRTEM studies. The particle size of the CQ-ZnONPs and CQ-CS/ZnONCs was 243.3 nm and 176.6 nm, with a PDI of 0.188 and 0.199, respectively. Nanoparticles and nanocomposites expressed Zeta potential of -15.7 mV and -16.2 mV, respectively. The CQ-ZnONPs and CQ-CS/ZnONCs showed good radical effectiveness with various in-vitro assays. The formulated nanoparticles and nanocomposites displayed significant antibacterial activity against the selected bacterial pathogens. CQ-CS/ZnONCs presented noteworthy α-amylase and α-glucosidase inhibitory effects compared to CQ-ZnONPs with IC50 of 73.66 ± 1.21 µg/mL and 87.59 ± 1.29 µg/mL, respectively. Moreover, the synthesized CQ-CS/ZnONCs demonstrated 98.92 ± 0.39% and 99.58 ± 0.16% wound contraction (at 7 and 14 mg, respectively), significantly (p < 0.05) higher than the standard and CQ-ZnONPs. Thus, the CQ-ZnONPs and CQ-CS/ZnONCs could effectively develop promising drug delivery systems to inhibit pathogens and chronic tissue repair.

RESUMO

Chronic, non-healable wounds have been a threat throughout history and have consumed centuries of traditional and modern research. In wound repair, a growing variety of novel treatments have been developed. At various stages of wound healing, nanostructure systems are employed. The drug may be synthesized at the nanoscale to act as a "provider," or nanomaterial could be employed as biomedical devices. Capparis zeylanica was used to synthesize Titanium dioxide nanoparticles (TiO2NPs) under ambient temperature. The UV-Vis spectrophotometer was used to confirm the illumination of fabricated TiO2NPs tuned to a size of 352 nm TiO2NPs have been revealed to be spherical and linked to one another using scanning electron microscopy. Biologically active functionality molecules involved in green synthesized TiO2NPs were indicated by Fourier transform infrared spectroscopy peaks. The TiO2NPs are amorphous, according to X-ray diffraction spectra. Skin diseases causing pathogens were studied for anti-microbial activity using the agar well diffusion method, and the results indicated significant anti-microbial properties. Furthermore, the wound healing ability of fabricated TiO2NPs was investigated in an excision wound model in Swiss albino mice. Finally, our findings revealed that TiO2NPs had provided a unique therapeutic approach for wound healing and in the planning of therapies.

RESUMO

INTRODUCTION: The objective of the reported work was to develop Montelukast sodium (MS) solid lipid nanoparticles (MS-SLNs) to ameliorate its oral bio-absorption. Herein, the highpressure homogenization (HPH) principle was utilized for the fabrication of MS-SLNs. METHOD: The study encompasses a 23 full factorial statistical design approach where mean particle size (Y1) and percent entrapment efficiency (Y2) were screened as dependent variables while, the concentration of lipid (X1), surfactant (X2), and co-surfactant (X3) were screened as independent variables. The investigation of MS-SLNs by DSC and XRD studies unveiled the molecular dispersion of MS into the SLNs while TEM study showed the smooth surface of developed MSSLNs. The optimized MS-SLNs exhibited mean particle size (MPS) = 115.5 ± 1.27 nm, polydispersity index (PDI) = 0.256 ± 0.04, zeta potential (ζ) = -21.9 ± 0.32 mV and entrapment efficiency (EE) = 90.97 ± 1.12 %. The In vivo pharmacokinetic study performed in Albino Wistar rats revealed 2.87-fold increments in oral bioavailability. RESULTS: The accelerated stability studies of optimized formulation showed good physical and chemical stability. The shelf life estimated for the developed MS-SLN was found to be 22.38 months. CONCLUSION: At the outset, the developed MS-SLNs formulation showed a significant increment in oral bioavailability and also exhibited excellent stability in exaggerated storage conditions.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Trachyspermum roxburghianum (DC.) H. Wolff, commonly known as 'Ajamoda,' is a neglected Indian spice highly used in Ayurveda and folklore remedies as an antimicrobial for chronic wounds and discharges, along with many other disease conditions. AIM OF THE STUDY: The objective of the study was to explore chemical composition and to investigate the antioxidant, antimicrobial, analgesic, and wound healing activities of T. roxburghianum fruit essential oil from India. MATERIALS AND METHODS: The phytochemical characterization of the oil was determined through standard qualitative procedures and the gas chromatography-mass spectrometry (GC-MS) technique. The in vitro antioxidant aptitude was assessed by scavenging DPPH and ABTS radicals. The antimicrobial potential of the oil was investigated using the disc diffusion method, followed by the determination of minimum inhibitory concentration against Gram-positive and Gram-negative bacterial and fungal strains. The analgesic potential was evaluated using thermal and chemically induced pain models in Swiss albino mice. Wound healing was assessed in vivo, including determining wound contraction rates, histopathology, and hydroxyproline estimation, using the excision wound model in Swiss albino mice. RESULTS: GC-MS analysis identified 55 compounds with major terpenoids, including thymol (13.8%), limonene (11.5%), and others. Substantial radical-scavenging activity was exhibited by T. roxburghianum fruit essential oil (TREO) (IC50 94.41 ± 2.00 µg/mL in DPPH assay and 91.28 ± 1.94 µg/mL in ABTS assay). Microorganisms were inhibited with low MIC (2 µL/mL for the inhibition of Staphylococcus aureus and Bacillus subtilis; 4 µL/mL against Salmonella typhi and 16 µL/mL against Candida albicans). In the cytotoxicity study, no cytotoxicity was observed on the Monkey Normal Kidney Cell line (Vero). Significant antinociceptive effects were observed (25.47 ± 1.10 % of inhibition at 100 mg/kg and 44.31 ± 1.69 % at 200 mg/kg). A remarkable rate of wound closure and epithelization, along with a marked increase in hydroxyproline content, were observed for the oil during wound healing in mice. CONCLUSIONS: The results suggested that oil could be utilized as a potential source of wound healing therapeutics.

RESUMO

INTRODUCTION: Psoriasis is a chronic skin condition caused by an autoimmune response that accelerates the life cycle of skin cells, resulting in the characteristic symptoms of scaling, inflammation, and itching. METHODS: Palliative treatment options for psoriasis often prioritize the use of volatile oils. These oils contain monoterpenes, sesquiterpenes, and phenylpropanoids that are intricately linked to the molecular cascades involved in the pathogenesis and symptoms of psoriasis. To evaluate the antipsoriatic efficacy of volatile oils and their components, we conducted a systematic review of scientific studies. Our literature search encompassed various online databases, including PubMed, BIREME, SCIELO, Open Grey, Scopus, and ScienceDirect. The selected studies included experimental in vitro/in vivo assessments as well as clinical studies that examined the potential of volatile oils and their extracts as antipsoriatic agents. We excluded conference proceedings, case reports, editorials, and abstracts. Ultimately, we identified and evaluated a total of 12 studies for inclusion in our analysis. RESULTS: The data collected, compiled, and analyzed strongly support the interaction between volatile oils and their constituents with the key molecular pathways involved in the pathogenesis of psoriasis and the development of its symptoms. Volatile oils play a significant role in the palliative treatment of psoriasis, while their chemical constituents have the potential to reduce the symptoms and recurrence of this condition. CONCLUSION: The current review highlights that the constituents found in volatile oils offer distinct chemical frameworks that can be regarded as promising starting points for the exploration and development of innovative antipsoriatic agents.

RESUMO

This work aimed to investigate the chemical composition, antioxidant activity, antinociceptive effect, and wound healing activity of the Lonicera caprifolium L. flower essential oil (LCEO). Linalool (16.42%), d-limonene (9.99%), and α-cadinol (10.65%) were the most prevalent components of the LCEO. The LCEO revealed moderate DPPH and ABTS radical-scavenging activity. LCEO exhibited potent antinociceptive activity in acetic acid-induced writhing and hot plate-induced pain model; LCEO reduced 73.88 ± 2.78% of writhing and significantly increased pain withdrawal latency in the mice, respectively. The LCEO also presented a potent wound healing effect, with 98.08 ± 1.37% wound closure on the 12th day of treatment. The results of the study demonstrate antioxidant and wound healing potential with antinociceptive effect. To the best of our knowledge, this is the first report on the bioactivities of L. caprifolium L. essential oil.

RESUMO

The present research work aimed at synthesizing chitosan-coated Zinc oxide nanocomposites (NS-CS/ZnONCs) by a bio-inspired method using an aqueous extract of Nigella sativa (NS) seeds and employing a quality-by-design approach (Box-Behnken design). The biosynthesized NS-CS/ZnONCs were physicochemically characterized and subjected to their in-vitro and in-vivo therapeutic potential. The zeta potential value of -11.2 mV and -12.6 mV indicated the stability of NS-mediated synthesized zinc oxide nanoparticles (NS-ZnONPs) and NS-CS/ZnONCs, respectively. The particle size of NS-ZnONPs and NS-CS/ZnONCs were 288.1 nm and 130.2 nm, respectively, with PDI of 0.198 and 0.158. NS-ZnONPs and NS-CS/ZnONCs showed superior radical scavenging abilities, excellent α-amylase, and α-glucosidase inhibitory activities. Also, NS-ZnONPs and NS-CS/ZnONCs demonstrated effective antibacterial activity against selected pathogens. Furthermore, NS-ZnONPs and NS-CS/ZnONCs demonstrated significant (p < 0.001) wound closure with 93.00 ± 0.43 % and 95.67 ± 0.43 % on the 15th day of treatment at the dose of 14 mg/wound, compared to 93.42 ± 0.58 % of standard. Collagen turnover was represented by hydroxyproline, which was shown to be significantly (p < 0.001) higher in the NS-ZnONPs (60.70 ± 1.44 mg/g of tissue) and NS-CS/ZnONCs (66.10 ± 1.23 mg/g of tissue) treatment groups than in the control group (47.7 ± 0.81 mg/g of tissue). Thus the NS-ZnONPs and NS-CS/ZnONCs could effectively develop promising drugs to inhibit pathogens and chronic tissue repair.

RESUMO

The promising therapeutic implications of nanoparticles have spurred their development for biomedical applications. An eco-friendly methodology synthesizes gold nanoparticles using Cordyceps militaris, an edible mushroom (Cord-Au-NPs), using a quality-by-design approach (central composite design). UV-visible spectroscopy analysis revealed an absorption peak at 540-550 nm, thus confirming the synthesis of gold nanoparticles. Cord-Au-NPs have a crystalline structure, as evidenced by the diffraction peaks. The zeta potential value of -19.42 mV signifies the stability of Cord-Au-NPs. XRD study shows gold facets and EDX analysis revealed a strong peak of spherical nanoparticles in the gold region with a mean particle size of 7.18 nm and a polydispersity index of 0.096. The obtained peaks are closely associated with phenolic groups, lipids, and proteins, as examined by FTIR, suggesting that they function as the reducing agent. Cord-Au-NPs exhibited dose-dependent antioxidant, antidiabetic, and antibacterial activity. The method is eco-friendly, nontoxic, less time-consuming, and does not use synthetic materials, leading to higher capabilities in biomedical applications.

RESUMO

The anti-inflammatory effect of the ethyl acetate extract of F. microcarpa bark (EAFMB) was investigated in acute and chronic (21 days) inflammation induced in Wistar albino rats. EAFMB (200 mg/kg b.w.) exhibited comparable anti-inflammatory effects to the reference drug, with a reduction of 59.48% at 4 h in acute inflammation and 83.96% on day 21 in chronic inflammation. Bioassay-guided fractionation using DPPH radical scavenging activity led to isolating and identifying three compounds from EAFMB: oleanolic acid, catechin, and p-hydroxycinnamic acid. All these compounds demonstrated the concentration-dependent inhibition of COX enzymes and the protection of egg albumin from heat-induced denaturation. Catechin exhibited the highest COX inhibition (COX-1 and COX-2 IC50 = 9.02 and 50.38 µM, respectively) and anti-denaturation effect (IC50 = 27.13 µg/mL) compared to oleanolic acid and p-hydroxycinnamic acid. These isolated compounds are likely responsible for the anti-inflammatory activities of F. microcarpa bark.

RESUMO

Psidium guajava L. is a small evergreen tree known for its magnificent medicinal and nutritional value. This study aimed to evaluate the nutritional profile and in vitro pharmacological potentialities of the different leaf extracts of four cultivars of Psidium guajava namely Surka chitti, Allahabad safeda, Karela, and Lucknow-49. The standard procedures of the Association of Official Analytical Chemists (AOAC) were followed to carry out the nutritional analysis and all of the cultivars recorded the presence of elements at a nominal range. The highest presence of phenols (125.77 mg GAE/g) and flavonoids (92.38 mg QE/g) in the methanolic leaf extract of the Karela cultivar was recorded. A wide range of minerals such as sodium, phosphorus, magnesium, zinc, and boron were recorded with a higher percentage in the Karela cultivar of Psidium guajava. In the enzyme inhibitory assays, Allahabad safeda showed potential inhibition with an IC50 of 113.31 ± 1.07, 98.2 ± 0.66 and 95.73 ± 0.39 µg/mL in α-amylase, α-glucosidase, and tyrosinase inhibition assays, respectively. The strong antioxidant effect was established by Lucknow-49 (IC50 of 74.43 ± 1.86 µg/mL) and Allahabad safeda (IC50 of 78.93 ± 0.46 µg/mL) for ABTS and DPPH assays, respectively. The ethyl acetate and methanolic leaf extracts of the Allahabad safeda cultivar showed better inhibition against Pseudomonas aeruginosa with an MIC of 14.84 and 28.69 µg/mL, respectively. A decent mean zone of inhibition was recorded in methanolic leaf extract that ranged from 21-25 mm in diameter against the tested bacterial strains (Proteus vulgaris, Bacillus subtilis, and P. aeruginosa). This is the first scientific report on the comparative and comprehensive analysis of indigenous guava cultivars to evidently shortlist the elite cultivars with enriched dietary nutrition and biological activities.

RESUMO

This study aimed to assess the phytochemical composition, in vitro antioxidant, cytotoxicity, and in vivo anti-inflammatory activities of the methanolic extract of Ailanthus excelsa (Simaroubaceae) stem bark and its fractions. Quantitative phytochemical analysis revealed that methanolic extract and all fractions contained a high level of flavonoids (20.40-22.91 mg/g QE), phenolics (1.72-7.41 mg/g GAE), saponins (33.28-51.87 mg/g DE), and alkaloids (0.21-0.33 mg/g AE). The antioxidant potential was evaluated in vitro using a range of assays, i.e., DPPH•, ABTS radical scavenging ability, and total antioxidant capacity. The chloroform and ethyl acetate fractions showed stronger antioxidant activity than the methanol extract. In vitro cytotoxic activity was investigated in three human tumor cell lines (A-549, MCF7 and HepG2) using the SRB assay. In addition, the in vivo anti-inflammatory effect was assessed by carrageenan-induced paw edema in rats. The chloroform fraction showed a more pronounced effect by effectively controlling the growth with the lowest GI50 and TGI concentrations. The human lung cancer cell line (A-549) was found to be more sensitive to the chloroform fraction. Furthermore, the chloroform fraction exhibited significant anti-inflammatory activity at a dose of 200 mg/kg in the latter phase of inflammation. Besides, methanol extract and ethyl acetate fraction revealed a significant cytotoxic and anti-inflammatory effects. The chloroform fraction of stem bark showed a strong anti-inflammatory effect in experimental animals and significant COX-2 inhibitory potential in the in vitro experiments. GC-MS analysis of chloroform fraction identified the phytochemicals like caftaric acid, 3,4-dihydroxy phenylacetic acid, arachidonic acid, cinnamic acid, 3-hydroxyphenylvaleric acid, caffeic acid, hexadeconoic acid, and oleanolic acid. The in-silico results suggest that identified compounds have better affinity towards the selected targets, viz. the BAX protein (PDB ID: 1F16), p53-binding protein Mdm-2 (PDB ID: 1YCR), and topoisomerase II (PDB ID: 1QZR). Amongst all, caftaric acid exhibited the best binding affinity for all three targets. Thus, it can be concluded that caftaric acid in combination with other phenolic compounds, might be responsible for the studied activity. Additional in vivo and in vitro studies are required to establish their exact molecular mechanisms and consider them as lead molecules in developing of valuable drugs for treating oxidative stress-induced disorders, cancers, and inflammations.

RESUMO

INTRODUCTION: The ethnobotanical survey of the South-western Satpuda ranges has continued for decades. However, very few disease-specific surveys and their pharmacological validation have been published. The present study aimed to identify, document, and pharmacologically validate the tribal knowledge on anti-inflammatory medicinal plants. METHODS: The field survey was conducted over a year from July 2015 to June 2016, scattered in the South-Western region of Satpuda Ranges. Documentation and identification of the medicinal herbs used often in the treatment of inflammatory conditions. Two plants, namely Eulophia herbacea Lindl., and Grewia flavescens A. Juss. were commonly used for inflammatory conditions. Phytopharmacological validation was done using carrageenan induced inflammation and CFA-induced arthritis. RESULTS: The current investigation identified 32 plants from 22 different families as anti-inflammatory plants. G. flavescens exhibited substantial antiarthritic action in complete Freund's adjuvant-induced arthritis in rats, and E. herbacea showed powerful anti-inflammatory activity in carrageenan-induced rat paw edema model. This activity might be attributed to the presence of gallic acid, quercetin, ß-sitosterol and lupeol. CONCLUSION: The research reveals that selected plants had anti-inflammatory properties in both acute and chronic inflammation. Further studies to highlight the exact mechanism of action of these plants are warranted.

RESUMO

Cassia glauca is reported as anti-diabetic medicinal plant and is also used as an ethnomedicine. However, its mode of action as an anti-diabetic agent has not been clearly elucidated. Hence, the present study investigated the probable mechanism of action of C. glauca to manage diabetes mellitus via network pharmacology and molecular docking and simulations studies. The reported bioactives from C. glauca were retrieved from an open-source database, i.e. ChEBI, and their targets were predicted using SwissTargetPrediction. The proteins involved in the pathogenesis of diabetes were identified from the therapeutic target database. The targets involved in diabetes were enriched in STRING, and the pathways involved in diabetes were identified concerning the KEGG. Cytoscape was used to construct the network among bioactives, proteins, and probably regulated pathways, which were analyzed based on edge count. Similarly, molecular docking was performed using the Glide module of the Schrodinger suite against majorly targeted proteins with their respective ligands. Additionally, the drug-likeness score and ADMET profile of the individual bioactives were predicted using MolSoft and admetSAR2.0 respectively. The stability of these complexes were further studied via molecular dynamics simulations and binding energy calculations. Twenty-three bio-actives were retrieved from the ChEBI database in which cassiarin B was predicted to modulate the highest number of proteins involved in diabetes mellitus. Similarly, GO analysis identified the PI3K-Akt signaling pathway to be primarily regulated by modulating the highest number of gene. Likewise, aldose reductase (AKR1B1) was majorly targeted via the bioactives of C. glauca. Similarly, docking study revealed methyl-3,5-di-O-caffeoylquinate (docking score -9.209) to possess the highest binding affinity with AKR1B1. Additionally, drug-likeness prediction identified cassiaoccidentalin B to possess the highest drug-likeness score, i.e. 0.84. The molecular dynamics simulations and the MMGBSA indicate high stability and greater binding energy for the methyl-3,5-di-O-caffeoylquinate (ΔG bind = -40.33 ± 6.69 kcal mol-1) with AKR1B1, thus complementing results from other experiments. The study identified cassiarin B, cassiaoccidentalin B, and cinnamtannin A2 as lead hits for the anti-diabetic activity of C. glauca. Further, the PI3K-Akt and AKR1B1 were traced as majorly modulated pathway and target, respectively.

RESUMO

Several species of Bridelia have been used in the condition of pain & arthritis in Indian folk medicine. Present study revealed the preliminary phytochemical investigation and evaluation of analgesic, anti-inflammatory and anti-arthritic activity as well as underlying mechanism of bark of Bridelia retusa Spreng. (Euphorbiaceae). The bark was subjected to extraction using pet.ether, ethyl acetate and acetone. All the extracts were significantly inhibit abdominal writhings response and licking time in late phase of formalin test. Extracts could also significantly inhibit mean paw edema of rats induced by carrageenan & histamine at dose of 200 & 400 mg/kg, i.p. Test materials also showed significant dose dependent reduction in cotton pellet granuloma & acetic acid induced vascular permeability at 400 mg/kg. Oral administration of B. retusa fractions in CFA induced arthritic rats, physical, biochemical and hematological parameters observed in arthritic animals were altered significantly to near normal condition. The maximum paw edema inhibition at day 21 was observed at 400 mg/kg. It also proved significant protection against protein denaturation & RBC membrane damage. The GC-MS analysis of EA extract revealed the presence of ß-sitosterol, stigmasterol, lupeol and friedelin (Pentacyclic triterpenoid). Therefore present study has demonstrated the analgesic; anti-inflammatory and anti-arthritic activities of B. retusa bark and suggested that the molecular membrane might be associated with inhibition of biochemical and hematological parameters. Overall bioactive profile of B. retusa used phytomedicine in future for inflammatory conditions.

RESUMO

BACKGROUND: Ficus microcarpa L. fil. (Syn: Ficus retusa) (Moraceae) is well-known traditional medicinal plant. The bark is used for diverse health ailments in traditional and folklore remedies. AIMS: The present study was undertaken to lay down pharmacognostical and phytochemical standards. MATERIALS AND METHODS: Pharmacognostic studies on fresh, dried and powdered bark was carried out to determine it's morphological, anatomical, and phytochemical diagnostic features. Furthermore, major phytoconstituents were identified from the extracts with the help of high performance liquid chromatography (HPLC) study. RESULTS: The morphology showed to be soft, brittle, rough, shallow vertical, irregularly oriented fissures, curved surface; with splintering, laminated fracture. Microscopically F. microcarpa showed all general characteristics of bark with some distinct differentiation. The phellem is thin and even, phelloderm few cell and rectangular and followed by smaller sclerides, the phloem rays are broad, multi-serrate and showed the scattered bundles of sclerides. The fluorescence and physicochemical standards for bark were established. HPLC analysis showed the predominant presence of therapeutically important phytoconstituents such as oleanolic, betulinic acid, lupeol, ß-sitosterol, catechin, and gallic acid. CONCLUSION: The bark of F. microcarpa considered equivalent to other Ficus species, such as Ficus virens, Ficus infectoria, Ficus arnottiana, Ficus lacor, and Ficus talboti. However, there is no pharmacognostical and phytochemical reports on F. microcarpa to authenticate and differentiate it from similar species. Present work has described pharmacognostical and phytochemical characteristics of F. microcarpa and diagnostic features to differentiate it.

RESUMO

Successive extracts of Ficus microcarpa L. fil. bark (FMB) were tested for antioxidant and hepatoprotective activity against carbon tetrachloride- and paracetamol-induced hepatotoxicities in rats. The ethyl acetate extract of FMB exhibited significant antioxidant and hepatoprotective activity by reducing carbon tetrachloride- and paracetamol-induced changes in biochemical parameters as evidenced by enzymatic and histological examination. Pretreatment with ethyl acetate extract of FMB significantly shortened the duration of pentobarbitone-induced necrosis in mice, indicating its hepatoprotective potential. Phytochemical studies confirmed the presence of the phenolic compound, catechin, in FMB, which may interfere with free-radical formation and may account for its significant hepatoprotective effects. The present study thus provides a scientific rationale for the traditional use of this plant in the management of liver disorders.
