ABSTRACT

Salinity stress is a prominent environmental factor that presents obstacles to the growth and development of plants. When the soil contains high salt concentrations, the roots face difficulties in absorbing water, resulting in water deficits within the plant tissues. Consequently, plants may experience inhibited growth, decreased development, and a decline in biomass accumulation. The use of nanoparticles has become a popular amendment in recent times for the alleviation of salinity stress. The study investigated the biological approach for the preparation of Se nanoparticles (NP) and their effect on the growth of wheat plants under saline conditions. The leaf extract of lemon (Citrus limon L.) was used for the green synthesis of selenium nanoparticles (Se-NPs). The synthesized NPs were characterized by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) and were applied foliar in the range of 0.01%, 0.05% and 0.1% on wheat plants. Results showed that 0.1% SeNP alone exhibited a significantly higher yield per plant, biomass per plant, 1000 grains weight, chlorophyll a, chlorophyll b and total chlorophyll over the SS (salt stress) control. A significant decline in MDA and H2O2 also validated the effectiveness of 0.1% SeNP over the SS control.

ABSTRACT

Hepatitis C virus (HCV) causes various liver complications, including fibrosis, cirrhosis, and steatosis, and finally progresses toward hepatocellular carcinoma (HCC). The current study aimed to explore the antiviral activity of the traditional Pakistani medicinal plant Salix nigra (S. nigra) known as black willow against the hepatitis C virus (HCV). The anti-HCV activity of S. nigra was established against stable Hep G2 cell lines expressing the HCV NS3 gene. Various plant-derived compounds with anti-HCV activity were identified, making phytotherapy a promising alternative to conventional treatments due to their cost-effectiveness and milder side effects. The two extraction methods (Maceration and Soxhlet) and four solvents (n-hexane, methanol, ethyl acetate, and water) were used to obtain crude extracts from S. nigra. Cytotoxicity testing showed that methanol (CC50 25 µg/mL) and water (CC50 30 µg/mL) extracts were highly toxic, while ethyl acetate and n-hexane (CC50 > 200 µg/mL) extracts were nontoxic at low concentrations (10-50 µg/mL), making them suitable for further anti-HCV investigations. Stable transfection of the NS3 gene was successfully performed in Hep G2 cells, creating a cellular expression system for studying virus-host interaction. The ethyl acetate extract of S. nigra exhibited significant inhibition of NS3 gene expression (mRNA and protein levels). The phytochemical analysis of S. nigra was also performed using the high-performance liquid chromatography (HPLC) technique. The phytochemical analysis identified several polyphenolic substances in the extracts of S. nigra. Our results concluded that the extracts of S. nigra have significantly reduced the expression of the NS3 gene at mRNA and protein levels. These findings contribute to the global efforts to combat hepatitis C by offering plant-based treatment options for HCV management.

ABSTRACT

The goal of this study was to extract saponins from the tuberous root of Decalepis hamiltonii and assess their potential clinical applications, which included antioxidant, antibacterial, antithrombotic, and anticancer properties. Surprisingly, the results of this study revealed that the extracted saponins have excellent antioxidant activities, as demonstrated by 2,2-diphenylpicrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), Hydrogen peroxide (H2O2), and Nitric oxide (NO) scavenging assays. Nonetheless, at a concentration of 100 g/mL, crude saponin had excellent antibacterial activity, particularly against gramme positive bacteria (Staphylococcus aureus, Bacillus subtilis, Staphylococcus epidermidis, and Micrococcus luteus), followed by gramme negative bacteria (Escherichia coli, Salmonella typhi, Proteus mirabilis, and Klebsiella pneumonia). Despite this, the crude saponin had no effect on Aspergillus niger and Candida albicans. The crude saponin also possesses outstanding in vitro antithrombotic activity on blood clot. Interestingly, the crude saponins have an outstanding anticancer activity of 89.26%, with an IC50 value of 58.41 µg/mL. Overall, the findings conclude that crude saponin derived from D. hamiltonii tuberous root could be used in pharmaceutical formulations.

ABSTRACT

Allium sativum (A. sativum)is well known for its therapeutic and culinary uses. Because of their high medicinal properties, the clove extract was selected to synthesize cobalt-tellurium nanoparticles. The aim of the study was to evaluate the protective activity of the nanofabricated cobalt-tellurium using A. sativum (Co-Tel-As-NPs) against H2O2-induced oxidative damage in HaCaT cells. Synthesized Co-Tel-As-NPs were analyzed using UV-Visible spectroscopy, FT-IR, EDAX, XRD, DLS, and SEM. Various concentrations of Co-Tel-As-NPs were used as a pretreatment on HaCaT cells before H2O2 was added. Then, the cell viability and mitochondrial damage were compared between pretreated and untreated control cells using an array of assays (MTT, LDH, DAPI, MMP, and TEM), and the intracellular ROS, NO, and antioxidant enzyme production were examined. In the present research, Co-Tel-As-NPs at different concentrations (0.5, 1.0, 2.0, and 4.0µg/mL) were tested for toxicity using HaCaT cells. Furthermore, the effect of H2O2 on the viability of HaCaT cells was evaluated using the MTT assay for Co-Tel-As-NPs. Among those, Co-Tel-As-NPs at 4.0 µg/mL showed notable protection; with the same treatment, cell viability was discovered to be 91% and LDH leakage was also significantly decreased. Additionally, the measurement of mitochondrial membrane potential was significantly decreased by Co-Tel-As-NPs pretreatment against H2O2. The recovery of the condensed and fragmented nuclei brought about by the action of Co-Tel-As-NPs was identified using DAPI staining. TEM examination of the HaCaT cells revealed that the Co-Tel-As-NPs had a therapeutic effect against H2O2 keratinocyte damage.

ABSTRACT

The biosynthesis of AgNPs using a methanolic extract of Naringi crenulata is described in this study. UV-visible spectroscopy, X-ray diffraction (XRD), Energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), particle size analyzer (PSA), scanning electron microscope (SEM), atomic force microscopy (AFM), and transmission electron microscopy (TEM) were used to characterize the synthesized AgNPs. The UV-visible spectrum revealed a sharp peak at 420 nm, which represents silver's strong Plasmon resonance. FTIR and XRD confirmed the functional groups (N-H stretch, alkanes, O-H stretch, carboxylic acid, N-H bend, C-X fluoride, and C-N stretch) and face-centered cubic crystalline structure of synthesized AgNPs. SEM and TEM analyses revealed that the synthesized nanoparticles had a spherical morphology with an average diameter of 32.75 nm. The synthesized AgNPs have antibacterial activity against multidrug-resistant bacteria pathogens such as Vibrio cholerae, Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, and Klebsiella pneumoniae. AgNPs can be synthesized using a methanolic extract of Naringi crenulate, and the resulting particle may have wide range of biological applications.

ABSTRACT

The current study demonstrated a green, friendly, low-cost biosynthesis of silver nanoparticles (AgNPs) from Kigelia africana leaves (Lam.) Benth. extract (KAE) as both a major capping and reducing agent. The produced AgNPs were characterized using a variety of analytical methods, like the X-ray powder diffraction (XRD), HRTEM, Fourier transforms infrared (FTIR), and UV-Vis spectrophotometer. The formation of AgNPs with maximum absorbance at max = 435 nm was endorsed by surface plasmon resonance. FTIR analysis revealed that biological macromolecules of KAE were involved in the stabilization and synthesis of AgNPs. At the same time, HRTEM images revealed that the average particle size of the spherical AgNPs ranged from about 25 nm to 35 nm. Further, cytotoxicity assessment of AgNPs was done using the RINm5F insulinoma cell line with an MTT assay. Followed by, the RINm5F insulinoma cells treated with AgNPs and KAE, the expression of the Peroxisome proliferator-activated receptor gamma (PPARγ) gene was accessed. The results showed gene expression was upregulated in the RINm5F insulinoma cell line thus confirming AgNPs and KAE anti-diabetic efficacy. Furthermore, the findings show that nanotechnology has enhanced the effectiveness of current methodologies in gene expression and regulation which has contributed to the emergence of different forms of advanced regulatory systems.

ABSTRACT

The biosynthesis of metal oxide nanoparticles provides an excellent alternative to the chemical synthesis approach. The aim of the current study was a green and eco-friendly synthesis of zirconium nanoparticles (ZrNPs) from fruit peels of Punica granatum (Pomegranate). The synthesis of ZrNPs was confirmed using a UV-visible spectrophotometer. The functional groups present on surface of ZrNPs were analyzed using FTIR. The average size of obtained ZrNPs was analyzed using SEM and DLS and it was around 20-60 nm. The antimicrobial activity of obtained ZrNPs was tested against Gram-positive strains (Bacillus subtilis and Staphylococcus aureus), Gram-negative strains (Escherichia coli and Klebsiella pneumoniae) and Fungi (Aspergillus niger) by agar well diffusion method. ZrNPs showed maximum zone of inhibition against S. aureus (19 mm) and A. niger (18 mm) at the maximum concentration of 200 µg/mL. The antioxidant scavenging activity of obtained ZrNPs was analyzed using the following methods: DPPH radical scavenging activity, Hydroxyl radical scavenging activity, Ferric reducing antioxidant power and hydrogen peroxide radical scavenging activity. This the first and foremost study on ZrNPs synthesized using P. granatum fruit peel extract reporting their efficacy as antimicrobial agents against Bacteria and Fungi. Considering the tolerance of zirconium towards human body, it can also be used as antimicrobial coating material on human implants.

ABSTRACT

This research was performed to evaluate the silver nanoparticles (AgNPs) fabricating potential of aqueous shoot extract of Aristolochia bracteolata and also assess the free radicals scavenging potential of synthesized AgNPs. The results obtained from this study showed that the aqueous shoot extract of A. bracteolata has the potential to synthesize the AgNPs and it was initially confirmed by color change in the reaction blend as yellow to dark brownish. Subsequently, a clear absorbance peak was found at 425 nm in UV-visible spectrum analysis. The functional groups involved in the capping and stabilization of AgNPs were confirmed by Fourier Transform-Infrared spectroscopy (FTIR) analysis and recorded about 10 sharp peaks 3688, 3401, 2980, 2370, 1948, 1642, 1480, 1280, 782, and 628 cm-1. The Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM) observations revealed that the predominant shape of the AgNPs was spherical and size ranged from 41.43 to 60.51 nm. Interestingly, the green fabricated AgNPs showed significant free radicals scavenging activity and were confirmed with ferric reducing assay, 1, 1-diphenyl-2-picryl-hydrazyl (DPPH), H2O2 radicals, and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radicals scavenging activity. Thus, after a few in-vivo antioxidant studies, Aristolochia bracteolata-mediated AgNPs can be considered as an antioxidant agent.

ABSTRACT

In recent years, silver nanoparticles have been used as modern chemotherapeutic drugs to treat several cancers such as pancreatic, breast, prostate, and blood cancers. No previous reports demonstrated the in vitro anti-human pancreatic cancer effects of the novel chemotherapeutic drug formulated by silver nanoparticles containing Berberis thunbergii leaf (AgNPs). The synthesized AgNPs were characterized using different techniques including UV-vis. and FT-IR spectroscopy, X-ray diffraction, scanning electron microscopy (SEM), and TEM. All techniques approved the synthesized silver nanoparticles. The SEM and TEM exhibited a uniform spherical morphology and an average size of about 15 nm for the biosynthesized nanoparticles, respectively. The 4-(dimethylamino)benzaldehyde,2,2-diphenyl-1- pikrilhydrazil (DPPH) test revealed similar antioxidant potentials for B. thunbergii leaf aqueous extract, AgNPs, and butylated hydroxytoluene. AgNPs inhibited half of the DPPH molecules in the concentration of 108 µg/mL. To survey the anti-human pancreatic cancer activities of AgNO3 , B. thunbergii leaf aqueous extract, and AgNPs, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was used on common human pancreatic cancer cell lines. AgNPs had very low cell viability and anti-human pancreatic cancer effects dose-dependently against PANC-1, AsPC-1, and MIA PaCa-2. The IC50 values of the AgNPs were 259, 268, and 141 µg/mL against PANC-1, AsPC-1, and MIA PaCa-2 cell lines, respectively. It is thought that the AgNPs obtained can be used as an anticancer drug for the diagnosis of pancreatic cancer in humans after acceptance of the above findings in clinical study trials.

ABSTRACT

Wheat (Triticum aestivum L.) production is significantly altered by the infestation of sucking insects, particularly aphids. Chemical sprays are not recommended for the management of aphids as wheat grains are consumed soon after crop harvests. Therefore, determining the susceptibility of different wheat genotypes and selecting the most tolerant genotype could significantly lower aphid infestation. This study evaluated the susceptibility of six different wheat genotypes ('Sehar-2006', 'Shafaq-2006', 'Faisalabad-2008', 'Lasani-2008', 'Millat-2011' and 'Punjab-2011') to three aphid species (Rhopalosiphum padi Linnaeus, Schizaphis graminum Rondani, Sitobion avenae Fabricius) at various growth stages. Seed dressing with insecticides and plant extracts were also evaluated for their efficacy to reduce the incidence of these aphid species. Afterwards, an economic analysis was performed to compute cost-benefit ratio and assess the economic feasibility for the use of insecticides and plant extracts. Aphids' infestation was recorded from the seedling stage and their population gradually increased as growth progressed towards tillering, stem elongation, heading, dough and ripening stages. The most susceptible growth stage was heading with 21.89 aphids/tiller followed by stem elongation (14.89 aphids/tiller) and dough stage (13.56 aphids/tiller). The genotype 'Punjab-2011' recorded the lower aphid infestation than 'Faisalabad-2008', 'Sehar-2006', 'Lasani-2008' and 'Shafaq-2006'. Rhopalosiphum padi appeared during mid-February, whereas S. graminum and S. avenae appeared during first week of March. Significant differences were recorded for losses in number of grains/spike and 1000-grain weight among tested wheat genotypes. The aphid population had non-significant correlation with yield-related traits. Hicap proved the most effective for the management of aphid species followed by Hombre and Husk among tested seed dressers, while Citrullus colocynthis L. and Moringa oleifera Lam. plant extracts exhibited the highest efficacy among different plant extracts used in the study. Economic analysis depicted that use of Hombre and Hicap resulted in the highest income and benefit cost ratio. Therefore, use of genotype Punjab-2011' and seed dressing with Hombre and Hicap can be successfully used to lower aphid infestation and get higher economic returns for wheat crop.

ABSTRACT

Cytokinins (CKs) plays a key role in plant adaptation over a range of different stress conditions. Here, we analyze the effects of a cytokinin (i.e., kinetin, KN) on the growth, photosynthesis (rate of O2 evolution), PS II photochemistry and AsA-GSH cycle in Trigonella seedlings grown under cadmium (Cd) stress. Trigonella seeds were sown in soil amended with 0, 3 and 9 mg Cd kg-1 soil, and after 15 days resultant seedlings were sprayed with three doses of KN, i.e.,10 µM (low, KNL), 50 µM (medium, KNM) and 100 µM (high, KNH); subsequent experiments were performed after 15 days of KN application, i.e., 30 days after sowing. Cadmium toxicity induced oxidative damage as shown by decreased seedling growth and photosynthetic pigment production (Chl a, Chl b and Car), rates of O2-evolution, and photochemistry of PS II of Trigonella seedlings, all accompanied by an increase in H2O2 accumulation. Supplementation with doses of KN at KNL and KNM significantly improved the growth and photosynthetic activity by reducing H2O2 accumulation through the up-regulation AsA-GSH cycle. Notably, KNL and KNM doses stimulated the rate of enzyme activities of APX, GR and DHAR, involved in the AsA-GSH cycle thereby efficiently regulates the level of AsA and GSH in Trigonella grown under Cd stress. The study concludes that KN can mitigate the damaging effects of Cd stress on plant growth by maintaining the redox status (>ratios: AsA/DHA and GSH/GSSG) of cells through the regulation of AsA-GSH cycle at 10 and 50 µM KN under Cd stress conditions. At 100 µM KN, the down-regulation of AsA-GSH cycle did not support the growth and PS II activity of the test seedlings.

ABSTRACT

The intention of this research was to find the most eminent metal tolerant and absorbing autochthonous fungal species from the waste dump of a bauxite mine. Out of the 4 (BI-1, BI-II, BI-III, and BI-IV) predominant isolates, BI-II had an excellent metal tolerance potential against most of the metals in the subsequent order: Cr(VI) (1500), Cu(II) (600), Pb(II) (500), and Zn(II) (500-1500 µg mL-1). BI-II had shown tolerance to Cr(VI) up to 1500 mg L-1. The excellent metal tolerant isolate was characterized and identified as Aspergillus tubingensis AF3 through 18S rRNA sequencing method and submitted to GenBank and received an accession number (MN901243). A. tubingensis AF3 had the efficiency to absorb Cr(VI) and Cu(II) at <70 & 46.3% respectively under the standard growth conditions. Under the optimized conditions (25 °C, pH 7.0, 0.5% of dextrose, and 12 days of incubation), A. tubingensis AF3 absorbed 74.48% of Cr(VI) in 12 days (reduction occurred as 822.3, 719.13, 296.66, and 255.2 mg L-1 of Cr(VI) on the 3rd, the 6th, the 9th and the 12th day, respectively). The adsorbed metal was sequestered in the mycelia of the fungus in a precipitated form; it was confirmed by Scanning Electron Microscope (SEM) and Energy Dispersive X-ray analysis (EDX) analyses. The possible biosorption mechanisms were analyzed by Fourier-Transform Infrared Spectroscopy (FTIR) analysis, the results showed the presence of N-H primary amines (1649.98 cm-1) and Alkanes (914.30 cm-1) in the cell wall of the fungus, while being treated with Cr(VI) they supported and enhanced the Cr(VI) absorption. The entire results concluded that the biomass of A. tubingensis AF3 had the potential to absorb a high concentration of Cr(VI).

ABSTRACT

BACKGROUND: Leelamine (LEE) is a lipophilic diterpene amine phytochemical, which can be naturally extracted from pine's bark trees. It has been extensively studied recently for its promising chemopreventive and anti-cancer effects against various cancers such as that of prostate and breast. HYPOTHESIS: We examined the potential impact of LEE in affecting the activation of signal transducer and activator of transcription 3 (STAT3) and promoting apoptosis in human multiple myeloma (MM) cells. METHODS: We evaluated the effect of LEE on STAT3 signaling pathway in MM cells by using Western blot analysis and reverse transcription polymerase chain reaction (RT-PCR). Thereafter, apoptosis was evaluated using cell cycle analysis and Annexin V assay. RESULTS: We noted that LEE could attenuate the phosphorylation of STAT3 and other up-stream signaling molecules such as JAK1, JAK2, and Src activation in U266 and MM.1S cells. It also diminished STAT3 translocation into the nucleus and enhanced the expression of protein-tyrosine phosphatase epsilon (PTPε). Additionally, LEE caused cell cycle arrest and synergistically augmented the apoptotic actions of bortezomib against MM cells. CONCLUSIONS: Our data indicates that LEE could block STAT3 signaling cascade linked to tumorigenesis and can be used in combination with approved anti-cancer agents in attenuating MM growth and survival.

ABSTRACT

This study deals with the green synthesis of chromium oxide (Cr2O3) nanoparticles using a leaf extract of Abutilon indicum (L.) Sweet as a reducing and capping agent. Different characterization techniques were used to characterize the synthesized nanoparticles such as X-ray diffraction (XRD), Scanning electron microscope (SEM), Transmission electron microscope (TEM), Energy-dispersive X-ray (EDX), Fourier transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS), and ultraviolet-visible (UV-VIS) spectroscopy. The X-ray diffraction technique confirmed the purity and crystallinity of the Cr2O3 nanoparticles. The average size of the nanoparticles ranged from 17 to 42 nm. The antibacterial activity of the green synthesized nanoparticles was evaluated against four different bacterial strains, E. coli, S. aureus, B. bronchiseptica, and B. subtilis using agar well diffusion and a live/dead staining assay. The anticancer activities were determined against Michigan Cancer Foundation-7 (MCF-7) cancer cells using MTT and a live/dead staining assay. Antioxidant activity was investigated in the linoleic acid system. Moreover, the cytobiocompatibility was analyzed against the Vero cell lines using MTT and a live/dead staining assay. The results demonstrated that the green synthesized Cr2O3 nanoparticles exhibited superior antibacterial activity in terms of zones of inhibition (ZOIs) against Gram-positive and Gram-negative bacteria compared to plant extracts and chemically synthesized Cr2O3 nanoparticles (commercial), but comparable to the standard drug (Leflox). The green synthesized Cr2O3 nanoparticles exhibited significant anticancer and antioxidant activities against MCF-7 cancerous cells and the linoleic acid system, respectively, compared to chemically synthesized Cr2O3 nanoparticles. Moreover, cytobiocompatibility analysis displayed that they presented excellent biocompatibility with Vero cell lines than that of chemically synthesized Cr2O3 nanoparticles. These results suggest that the green synthesized Cr2O3 nanoparticles' enhanced biological activities might be attributed to a synergetic effect. Hence, green synthesized Cr2O3 nanoparticles could prove to be promising candidates for future biomedical applications.

ABSTRACT

Gastric carcinoma is one of the most aggressive types of cancer that ranks fifth among all cancer incidences and third in cancer mortality. As it exhibits a prolonged asymptomatic condition and high recurrence rate, it is a great challenge to treat gastric cancer. Traditional medicine that utilizes herbal phytochemicals to treat various diseases is a potent alternative for current allopathic treatment. Hence, we evaluated the potency of a phytochemical bilobalide for treating gastric cancer in in vitro and in vivo models. Bilobalide, a sesquiterpenoid, is present in the Ginkgo biloba plant that belongs to the family of Ginkgoaceae. The cytotoxicity effect of bilobalide was evaluated in both gastric cancer (AGS) cells and normal gastric epithelial cells. Apoptosis-inducing property of bilobalide against the AGS cell line was analyzed with different fluorescent staining techniques and terminal deoxynucleotidyl transferase dUTP nick-end labeling assay, and cell cycle analysis was carried out by flow cytometry. The in vivo studies were assessed with N-methyl-N-nitrosourea (MNU)-induced gastric cancer in rats. Serum-specific gastric markers were quantified and histopathological analysis of stomach tissue was performed. The expression of target-signaling molecules was analyzed by a reverse-transcription polymerase chain reaction. The in vitro results proved that bilobalide effectively suppressed the AGS cell growth and induced cell death by nuclear damage and apoptosis induction. The bilobalide treatment effectively arrested the cell cycle of AGS cells via inhibiting the PI3K-signaling pathway. Our in vivo results also confirmed that the bilobalide persuasively inhibited the MNU-induced gastric carcinoma via inhibiting the thioredoxin-fold family proteins and inflammatory markers' expression. Overall, our results authentically prove that bilobalide possesses therapeutic potency to cure gastric carcinoma.

ABSTRACT

Development of biologically inspired green synthesis of silver nanoparticles has been extensively scrutinized owing to its uses in biomedical industry. In the last two decades, the demands of nanomaterial in bone remodelling have increased. Scutellaria baicalensis is a flowering plant usually used for many ailments. This work explores the zinc oxide nanoparticles (ZnO NPs) by green route method from S. baicalensis and the therapeutic potentials of Sb-ZnONPs on differentiation of osteoblast and osteoclast formation inhibition. The characterization of the fabricated ZnO-NPs from S. baicalensis was done via different spectroscopic and microscopic techniques; ultraviolet-visible spectroscopy (UV-Vis), Fourier transform-infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), and dynamic light scattering (DLS). The Osteogenic-related tests (MTT, Mineralization assay and Real-time PCR) were used to evaluate the properties of SB-ZnONPs on the growth and proliferation of human osteoblast-like MG-63 cells. The characterization of SB-ZnONPs discovered the crystalline properties with high zinc content and the existence of bioactive mixtures from S. baicalensis extract. In addition, SB-ZnONPs showed insignificant cytotoxicity with enhanced differentiation, proliferation, and mineralization on MG-63 cells. Overall, these results denote that SB-ZnONPs is expected to be a natural source for the development of medical agents to in bone healing and remodelling.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: Demand for plant-based medications and therapeutics is increasing worldwide as of its potential effects and no toxic. Traditionally, so many medicinal plants are used to treat diabetes. Subsequently, investigation on medicinal plants was enduring to discover potential antidiabetic drugs. A. tetracantha is used traditionally to cure diabetes mellitus, cough, dropsy, chronic diarrhea, rheumatism, phthisis and smallpox. Scientifically, A. tetracantha has been reported as an antidiabetic agent. Friedelin, the isolated compound has been reported as hypolipidemic, antioxidant, scavenging of free radicals, antiulcer, anti-inflammatory, analgesic and antipyretic agent. AIM OF THE STUDY: To scrutinize the mechanism of antidiabetic activity of friedelin isolated from the leaves of A. tetracantha. MATERIALS AND METHODS: A. tetracantha leaves powder (5 kg) was soaked in hexane (15 L) to obtain hexane extract. Using column chromatography, the hexane extract was fractionated using a combination of solvents like hexane and ethyl acetate. 25 fractions were obtained and the fractions 13 and 14 yielded the compound, friedelin. Friedelin at the doses of 20 and 40 mg/kg was used to treated STZ -induced diabetic rats for 28 days. Later 28 days of treatment, the bodyweight changes, levels of blood glucose, insulin, SGOT, SGPT, SALP, liver glycogen and total protein were assessed. RESULTS: Friedelin significantly brought these altered levels to near normal. Moreover, friedelin also enhanced the translocation as well as activation of GLUT2 and GLUT4 through PI3K/p-Akt signaling cascade in skeletal muscles and liver on diabetic rats. CONCLUSION: This finding proved that friedelin has an anti-diabetic effect through insulin-dependent signaling cascade mechanism, thus it may lead to establishing a drug to treat type 2 diabetes mellitus.

ABSTRACT

Protocatechuic acid (PA) is widely distributed and commonly occurring natural compound that can exert antioxidant, anti-inflammatory, as well as anti-cancer effects. Epithelial-to-mesenchymal transition (EMT) is important cellular process that can control tumor invasion and metastasis. Here, we investigated whether PA can modulate the EMT process in basal and transforming growth factorß-induced A549 and H1299 cells. We found that PA suppressed expression of mesenchymal markers (Fibronectin, Vimentin, and N-cadherin), MMP-9, MMP-2, twist, and snail but stimulated the levels of epithelial markers (E-cadherin and Occludin). In addition, PA can affect TGFß-induced expression of both mesenchymal and epithelial markers. Moreover, PA abrogated migratory and invasive potential of tumor cells by reversing the EMT process. Furthermore, we found that PA suppressed EMT process by abrogating the activation of PI3K/Akt/mTOR signaling cascade in lung cancer cells.

ABSTRACT

Mushrooms have an important role in sustainability since they have long been used as valuable food source and traditional medicine around the world. Regrettably, they are among the most rigorously affected populations, along with several plants and animals, due to the destructive activities of mankind. Thus the authentication and conservation of mushroom species are constantly needed to exploit the remarkable potential in them. In this perspective, an attempt has been made to identify and assess the biological attributes of psychedelic mushrooms collected from Kodaikanal, Tamil Nadu, India. The macromorphological features of the psychedelic mushroom DPT1 helped its presumptive identification and the molecular characters depicted by DNA marker revealed its close relationship with the genus Psilocybe. Accordingly, the psychedelic mushroom was identified as Psilocybe cubensis DPT1 and its crude ethyl acetate extract on analysis revealed the occurrence of phytoconstituents like alkaloids, flavonoids, tannins, saponins and carbohydrates. Moreover, it exhibited 80% larvicidal activity against Culex quinquefasciatus mosquito at 800 ppm concentration and an array of antibacterial effects with utmost susceptibility of Proteus vulgaris, and the identification of bioactive compounds by different analytical techniques substantiate that the bioactivities might be due to the presence of phytochemicals. The results of the study indicated that the extract of P. cubensis DPT1 having notable antibacterial and mosquito larvicidal efficacies which could be probed further for the isolation of medicinally important as well as bio-control compounds.

ABSTRACT

The cotton fabrics are a cosmopolitan in usage due to their extraordinary features. The clothes are a very good medium for the growth of pathogenic microorganisms. The nanoparticles have diverse benefits in the biomedical field like drug carrier and as antimicrobials. The current investigation was aimed to synthesize the metallic silver nanoparticles (AgNPs) from the aqueous extract of Curcuma longa leaf and evaluating their antimicrobial and wound healing potential of AgNPs coated cotton fabric. The synthesized AgNPs were characterized by HR-TEM and FT-IR examinations. The formulated AgNPs were coated with cotton fabrics to test their efficiency against the pathogenic microorganisms. The existence of AgNPs in the cotton fabrics was confirmed via the SEM along with EDX analysis. The antimicrobial potential of fabricated AgNPs and its coated cotton fabrics was inspected against the human pathogenic strains. The wound healing efficacy was examined in the L929 cells. The HR-TEM analysis proved the existence of spherical shaped AgNPs. In the antimicrobial activity, the CL-AgNPs loaded cotton fabric was exhibited an appreciable decrease in the growth of pathogenic microorganisms. The crude extract, as well as formulated AgNPs, also exhibited the noticeable antimicrobial potency against the S.aureus, P.aeruginosa, S.pyogenes, and C.albicans. The AgNPs loaded cotton fabrics was displayed the potent wound healing activity in the fibroblast (L929) cells. Consequently, it was concluded that the formulated AgNPs from C.longa coated cotton fabrics may be utilized for the variety of applications in hospital patients and even medical workers to prevent the microbial infection.
