The assessment of antioxidant potential of Olea europaea and Ocimum basilicum and their comparative and combine study

Many chronic diseases, such as cancer and diabetes, are connected to the negative consequences of reactive oxygen species (ROS). Ocimum basilicum or basil is a plant that is high in eugenol and vitamin K and is recognized for its antioxidant qualities. Research has indicated that basil possesses strong anticancer properties, impacting multiple biological processes like autophagy, cell cycle regulation, inflammation management, apoptosis, and metastasis suppression. Analogously, Olea europaea (olive) is acknowledged for its hypotensive, anti-inflammatory, and antioxidant characteristics. Because of their anticancer properties, the polyphenols included in olive leaves have demonstrated therapeutic efficacy against specific forms of cancer. At doses of 100, 500, and 1000 µg/mL, respectively, the Olea europaea extract demonstrated dose-dependent antioxidant activity with scavenging rates of 45%, 66%, and 83%. At the same concentrations, the Ocimum basilicum methanolic extract demonstrated antioxidant action as well, with scavenging rates of 11%, 43%, and 49%. Notably, both plants’ methanolic extracts showed increased antioxidant activity when combined. At doses of 100, 500, and 1000 µg/mL, the combined extracts demonstrated scavenging activities of 42%, 49%, and 71% using the DPPH free radical scavenging assay. This study's main goal is to assess the combined antioxidant capacity of methanolic extracts made from the leaves of Ocimum basilicum and Olea europaea. The results indicate that Ocimum basilicum and Olea europaea combination therapy considerably suppresses DPPH free radicals. With potential therapeutic effects, this combined therapy may be instrumental in scavenging free radicals that lead to the development of cancer.

Evaluation of Antidiabetic Activity of Abutilon crispum on Normal and Streptozotocin-induced Diabetic Albino Wistar Rats

Background Diabetes mellitus is a disorder that affects the majority of individuals in the world. Objectives The objective of the current study is to estimate the antidiabetic effect of methanol extract of Abutilon crispum entire plant, which is broadly cultivated in India’s arid and desert areas. This current investigation aims to estimate the efficacy of methanol extract of A. crispum to prevent streptozotocin-induced diabetes mellitus in Albino Wistar strain rats. Materials and Methods In the current examination, methanol extract of the whole plant of A. crispum with doses of 250 and 500 mg/kg/b.wt (body weight) is administered through the oral route to the streptozotocin-prompted diabetic animals where n = 6. We evaluated the differences in food and water intake, body weight levels, fasting glucose, and oral glucose tolerance test (OGTT). When methanol extract of A. crispum was used to evaluate the OGTT for diabetic animals, levels of glucose were found to be pointedly lower when administered with 500 mg/kg b.wt as this is compared to the control group. A. crispum had specifically declined the levels of glucose elevated in diabetic rats. A. crispum is a vital alternative source for managing blood glucose levels in diabetes mellitus that have increased during the condition and need to be further reduced by oral medications that cause hypoglycemia. Biochemical parameters were estimated as a part of the investigation. Results The results demonstrated that the dried methanol extract of A. crispum (250 mg/kg/bwt and 500 mg/kg/bwt) considerably declined those levels of blood glucose during the treatment period when compared to glibenclamide (10 mg/kg), enhanced the metabolism, improved the health of animals and enhanced the OGTT. Conclusion As a result, we can conclude that the whole plant of A. crispum methanol extract contains antidiabetic effects, as well as, hypoglycemic activities.

Haematology and histology studies on Moringa oleifera leaves and bark extracts in streptozotocin-induced diabetic albino rats

Alterations in haematological parameters are frequently observed in individuals with diabetes mellitus (DM). Oxidative stress has been identified as a contributing factor in the pathogenesis of organ damage and haematological dysfunction associated with DM. As a result, the potential positive impact of Moringa oleifera, a medicinal plant known for its antioxidant properties, on haematological parameters and kidney function in diabetic rats was investigated. A total of thirty-five rats were divided into seven groups, each consisting of five rats. Group I was administered only distilled water, while groups II to VII were induced with a single dose of 60mg/kg streptozotocin intraperitoneally. Subsequently, groups II to VI were treated with 150 mg/kg Moringa oleifera leaf methanol extract, 150 mg/kg Moringa oleifera bark methanol extract, 300 mg/kg Moringa oleifera leaf, 300 mg/kg Moringa oleifera bark, and metformin, respectively. The results showed positive modulation to most of the haematology parameters evaluated except neutrophils and lymphocytes by the treatments. The leaf extract showed a more significant modulation of platelets than other treatments. The histology of the kidney showed normal structure for all the treatments. Moringa oleifera especially the leaf extract is promising in the treatment of DM

Antioxidant, cytotoxic, anti-migratory, and pro-apoptotic effects of Bolanthus turcicus extracts on head and neck cancer cells.

Investigation of various plant extracts using in-vitro/in-vivo assays has emerged as a promising avenue for identifying potential pharmacophores that can be developed into therapeutic drugs. This study aims to assess the bioactive compounds and antioxidant capacity of the Bolanthus turcicus (B. turcicus) and to investigate the effects on head and neck cancer (HNC) cell lines. Methanol (MeOH), ethyl acetate (EA) and aqueous (Aq) extracts were prepared from B. turcicus, and the amount of total phenolic content (TPC) and total flavonoid content (TFC) in the extracts were analyzed by the Folin-Ciocalteu and Aluminum chloride method, respectively. In addition, the total antioxidant capacity and iron reducing potential of B. turcicus extracts were determined by the Phosphomolybdenum and Ferric ion reducing antioxidant power (FRAP) method. The effect of B. turcicus on HEp-2, SCC-90, SCC-9, FaDu HNC cell viability, motility, and cell-nuclear morphology was evaluated by MTT, scratch-wound healing assay, and Pllalloidin-DAPI staining, respectively. The effect of B. turcicus on the expression of CASP-3, BAX, and BCL-2 genes at the mRNA, protein, and intracellular level was evaluated by quantitative PCR (qPCR), western blot, and immunofluorescence staining. Moreover, Annexin V-FITC/PI, was used in flow cytometry to investigate the effect of B. turcicus on apoptosis. The MeOH extract exhibited the highest phenolic content, flavonoid content and antioxidant activity (p < 0.05 for all). HNC cells treated with extracts indicated delayed wound healing and decreased motility (p < 0.05 for all). Analysis of annexin V-PI staining indicated that the B. turcicus extracts induced apoptosis but not viability and necrosis in the HNC cell (p < 0.05 for all). Moreover, qPCR data regarding the apoptotic mechanism showed that the extracts could induce apoptosis by upregulation of pro-apoptotic CASP-3 and BAX genes and downregulation of anti-apoptotic BCL-2 gene (p < 0.05 for all). The expression of protein and intracellular levels of CASP-3 and BAX were increased, while the BCL-2 was decreased in cells treated with the extracts (p < 0.05 for all). In addition, diffuse pycnosis and DNA condensation in HNC cell nuclei, confirming apoptotic cell death (p < 0.05 for all). This study data indicated that B. turcicus extracts have antioxidant, cytotoxic, anti-migratory and pro-apoptotic activity. In conclusion, it has been shown that B. turcicus can be used as a potential therapeutic agent against HNC.

Improving sunflower oil stability with propolis: A study on antioxidative effects of Turkish propolis during accelerated oxidation.

Propolis, a natural resinous substance collected by bees, is known for its potent antioxidant properties. This study investigates the antioxidant activities and total phenolic contents of propolis samples from 16 provinces of Türkiye and their effects on the oxidative stability of sunflower oil. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) inhibition was in the range of 28.1%-92.5% in thirteen propolis samples, whereas this rate was 24.5% in butylated hydroxytoluene (BHT). Although 2,2'-azino-bis(3-ethylbenzotiazolin-6-sulfonic acid) (ABTS) value was 224µmol trolox/g in BHT, this value was in the range of 262-1370µmol trolox/g in propolis samples, except for one. Propolis methanol extracts 13 applied to sunflower oil at a concentration of 1000ppm were more efficient than BHT added at 200ppm for inhibiting the production of peroxide value (PV). Similarly, most propolis extracts (1000ppm) demonstrated antioxidant activity against the production of p-anisidine (p-AV) in sunflower oil under accelerated oxidation conditions. It was determined that Turkish propolis had strong antioxidant properties and delayed oxidation and may be utilized commercially in the food sector to delay the oxidation of fats and oils.

Nyctanthes arbor-tristis Improves Blood Pressure via Endothelial Pathway: In Silico, Ex Vivo, and In Vivo Evidence.

Systemic hypertension, a common metabolic disorder, poses significant health risks despite the availability of antihypertensive drugs. Nyctanthes arbor-tristis has garnered increasing attention for its perceived efficacy and safety, though its mechanisms of action and the bioactive compounds responsible for its antihypertensive effects remain elusive. Therefore, this study aims to elucidate the antihypertensive activity of N. arbor-tristis leaves in rats and explore associated mechanism through in silico, in vitro, ex vivo, and in vivo studies. The methanolic extract of N. arbor-tristis leaves (MENAT) was fractionated and subjected to qualitative and quantitative phytochemical screening, including total phenolic content (Folin-Ciocalteu method), total flavonoid content (Aluminum chloride method), and total alkaloid content (spectrometric method). Antioxidant studies were conducted using DPPH, FRAP, and H2O2 assays. The most promising fraction (WNAT) was analyzed using LC-MS, and the identified compounds were used for molecular docking studies against cGMP and eNOS. Further, aortic ring assays were conducted to assess ex vivo vasorelaxant activity (rat aortic strip assay) and the underlying mechanisms of WNAT. Later, in vivo studies using a DOCA-salt-induced hypertension model in Wistar rats, along with molecular analyses (RT-PCR), were performed to validate the antihypertensive claims of N. arbor-tristis. In vitro studies demonstrated that the water extract of N. arbor-tristis leaves (WNAT) exhibited strong antioxidant activity and contained key phytochemicals. LC-MS analysis revealed the presence of 19 major compounds, including betulinic acid and arbortristosides. Molecular docking studies indicated that arborside C exhibited a strong affinity for both eNOS and cGMP. Ex vivo studies involving rat aortic strips showed that WNAT induced vasodilatory activity, which is associated with parasympathetic and nitric oxide-related pathways. In vivo experiments further supported WNAT's antihypertensive properties through improvements via amelioration of rat blood pressure and histological features, biochemical markers, morphometric parameters, and gene expression in hypertensive rats. In conclusion, WNAT effectively lowers blood pressure through modulation of the endothelial pathway and warrants further studies to attain its clinical utility in hypertensive subjects.

Optimizing the production factors would able to commercialize the seaweeds in drug forms and could be used for the treatment of various diseases in humans.

Nematicidal efficacy of Cymbopogon nardus, Pelargonium graveolens essential oils and Annona squamosa extract against Meloidogyne incognita and M. graminicola

A crude hexane extract of seed kernel was processed into fatty acid methyl esters (FAME) using methanolic-sulfuric acid. Herbal mixtures (seed extracts of A. squamosa and essential oils of Cymbopogon nardus (citronella) and Pelargonium graveolens (geranium)) were evaluated against root knot nematode (Meloidogyne spp). The mortality of J2s of M. incognita in hexane and methanol extracts (AHE+AME) of A. squamosa with geranium oil (GO) ranged from 50.75-89.75% to 71.50-99.00% at 31.25 to 1000 μgmL-1 in 24 to 96 hours. The number of galls after CO+AHE+AME treatment was 4.0 ± 0.0 and 5.67 ± 0.58 galls/seedling and were recorded at 1000 and 500 μgmL-1 treatments on 30 days after inoculation, compared to carbofuran (3.0 ± 0.0 and 4.3 ± 0.6 galls/seedling) at 1000 and 500 μgmL-1 and velum prime (3.6 ± 0.6 and 4.6 ± 0.6 galls/seedling) at 1000 and 500 μgmL-1. The maximum shoot length of brinjal seedlings was recorded in CO+AHE+AME treatment compared to carbofuran (47.3 ± 0.6cm) and velum prime (48.7 ± 0.6 cm) at 1000 μg mL-1 in soil drenching application. Methanol and hexane extracts (AHE+AME) obtained from Annona squamosa seeds were investigated for their nematicidal properties. M. graminicola in direct-seeded rice at the nursery level and M. incognita in brinjal (eggplant) were controlled for up to sixty days when treated with these mixtures.

Inhibitory effects of wild Origanum elongatum extracts on Fusarium oxysporum mycelium growth and spores germination: Evidence from in-vitro, in-planta, and in-silico experiments

Fusarium wilt, caused by Fusarium oxysporum, is one of the most devastating diseases to crops including potatoes. This fungus is widespread and dispersed via resistant spores. In this study, organic (methanol, hexane, and chloroform) and aqueous extracts of the aerial parts of wild Origanum elongatum were tested against mycelium and spores of F. oxysporum in both in-vitro (using the poisoned food technique) and in-planta assays. Further, the chemical composition of the extract was identified via HPLC-PDA-MS/MS. Then, molecular modeling was used to clarify the antifungal activity of identified biomolecules. The obtained results showed that organic and aqueous extracts showed significant antifungal and anti-sporulation activities with different effectiveness depending on the extract, concentration, and application test. In in-vitro assays of the aqueous extract, the highest antifungal activity was recorded at concentrations of 10 mg mL−1, while the highest anti-sporulation activity (91.79 %) was observed at 50 mg mL−1. In the organic extracts, methanol was the most effective against fungus with 100 % inhibition of mycelium at 5 mg mL −1 and the highest anti-sporulation effect (73.58 %) at 20 mg mL−1. In in-planta assays, the methanolic extract at 20 mg mL−1 achieved 0 % disease severity, while the aqueous extract at 50 mg mL−1 reduced severity to 7 %, both significantly more effective than the untreated control. Therefore, methanol was the most effective and these biological properties are supported by a wide range of bioactive molecules, including 56 molecules compared to only 28 molecules in the aqueous extract. These include glycosides of apigenin and kaempferol and salvianolic acid b. However, more research is needed to clarify the inhibition action of the individual components and their synergetic actions in controlled and field conditions.

Isolation, Characterization, and Anti-Inflammatory Effects of β-Sitosterol-β-D-Glucoside from Hygrophila auriculata: Experimental Validation, Molecular Docking, and Molecular Dynamics Simulations.

Hygrophila auriculata (K. Schum) Heine is known to treat various common aliment e.g. rheumatoid arthritis, kidney infections, jaundice, edema, and gout. This study aims to isolate bioactive components from the methanolic extract, assess their anti-inflammatory effects, and investigate their interactions with drug targets through docking and molecular dynamics simulations. Methanolic extract of H. auriculata furnished stigmast-5-en-3-ol-β-D-glucopyranoside (HA-06) which was characterized by using IR, NMR and mass spectral data. HA-06 alleviated carrageenan-induced inflammation in rats, while the methanolic extract of H. auriculata produced comparable results. The findings were similar to those of the positive control, indomethacin. The chemical structure of HA-06 was optimized using DFT at the B3LYP level and subsequently used for molecular docking against anti-inflammatory drug targets. HA-06 exhibited strong affinity towards phospholipase A2 and glucocorticoid receptor exhibiting binding energies of -11.25 kcal/mol and -11.07 kcal/mol, respectively.Molecular dynamics simulation was used to assess the dynamical stability of these two complexes and their native co-crystallized ligands. Principal component analysis, radius of gyration, free energy landscapes, solvent-accessible-surface-area, and root-mean square deviation/fluctuation all indicated stable interactions. Therefore, HA-06 could be a promising candidate for development into an effective therapy against inflammatory diseases targeting phospholipase A2 and glucocorticoid receptor.

Wall. ex Nees, used in Nigeria's ethno-medicine, was investigated for its radical scavenging and antimicrobial properties, as well as its phytochemical composition, using gas chromatography-mass spectrometric (GC-MS) analysis. In vitro antioxidant activity of the methanol extract of the whole plant was tested through four different assays: DPPH, ABTS, FRAP, and NOx. The GC-MS analysis revealed the presence of neophthadiene (29.42%), followed by ergost-5-en-3-ol (10.57%), and methyl sterate (7.29%) as the major compounds present in the methanol extract of Andrographis paniculata. The methanol extract showed promising antioxidant activity compared with the reference (ascorbic acid). It was observed that the activity was concentration dependent, and values of 86.12±0.03, 90.18±0.03, 80.20±0.04, and 92.15±0.06 were obtained for DPPH, ABTS, FRAP, and NOx, respectively, under the same condition. All the tested bacteria (gram positive and gram negative) were inhibited by the methanol extract of Andrographis paniculata, except Proteus mirabilis, which showed a resistance at lower concentrations (0.25 mg/ml and 0.50 mg/ml). These findings suggest the bioactive potentials of Andrographis paniculata (Burm.f.) Wall. ex Nees, supporting its traditional use in Nigerian ethnomedicine and highlighting potential applications in pharmaceuticals.

The ANTIOXIDANT AND PHYTOCHEMICAL ANALYSIS OF METHANOL EXTRACT OF PHYLLANTHUS AMARUS

Phyllanthus amarus is a widely recognized plant that has been traditionally utilized to cure a variety of ailments. The current study explored the phytochemical and antioxidant characteristics of P. amarus methanol extract. Standard procedures were used to analyze: 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) percentage (%) inhibition, lipid peroxidation % inhibition, total phenolic content (TPC) and total flavonoid content (TFC). A higher quantity of the plant extract resulted in a greater inhibition of DPPH and lipid peroxidation percentage. The highest DPPH % inhibition (74.4%) and lipid peroxidation % inhibition (83.44%) were at 0.05 mg/ml while the lowest DPPH % inhibition (25.23%) and lipid peroxidation % inhibition (39.11%) was at 0.03 mg/ml (p &lt; 0.05). The most prevalent compound was flavonoid, with a TFC of 460.22 µg/ml while the TPC was 7.428 µg/ml. Owing to its antioxidant and phytochemical qualities, P. amarus methanol extract may potentially find application in medicine.

Assessment of loliolide extracted from Biserula pelecinus, present during in vitro oocyte maturation, on fertilisation and embryo development in sheep

Context As a ‘duty of care’, it is important to test whether new forage plants for ruminants contain secondary compounds (PSCs) that affect reproductive performance. We have previously observed, a posteriori, that the presence of a methanolic extract of Biserrula pelecinus during maturation of sheep oocytes increased fertilisation rate and blastocyst development. This result needed to be verified a priori and, if the outcome was repeated, we needed to identify the plant secondary metabolite responsible. Aims To test whether PSCs from B. pelecinus, when added to the oocyte maturation medium, improve fertilisation rate and blastocyst development; to test whether loliolide is the active molecule produced by B. pelecinus. Methods Methanol–chloroform extracts of B. pelecinus were fractionated using rapid silica filtration and solvents of increasing polarity. Fractions at final concentrations of 0, 100 or 200 μg mL−1 were added to the medium used to mature sheep cumulus–oocyte complexes (COCs) and effects were determined for maturation, subsequent cleavage rate, blastocyst rate, hatching rate, blastocyst efficiency and total blastocyst cell number (TCN). Results Fraction BP-6 at 100 μg mL−1 reduced blastocyst rate (P &lt; 0.05), but had no effect when the dose was doubled to 200 μg mL−1. Further fractionation using semi-preparative high-performance liquid chromatography showed loliolide as the most abundant compound in BP-6. Supplementation of the in vitro maturation medium with loliolide (0, 2.5, 5, 10 and 25 μg mL−1) did not affect any measure of embryo development. All COCs treated with B. pelecinus fractions reached the final stage of embryo development, blastocyst hatching. Total blastocyst cell number was not affected. Conclusion The presence of fractions of B. pelecinus extract during in vitro oocyte maturation can reduce embryo development. Implications In vitro techniques can detect potential effects of forages on reproduction. Some fractions from an extract of B. pelecinus when present during oocyte maturation can reduce embryo development. The abundant PSC, loliolide, was not responsible. There was no indication that a PSC in B. pelecinus improves outcomes.

Validation of a triiodothyronine (T3) ELISA for mouse fecal samples.

Acquiring sufficient blood for hormone analysis in mice can be a limiting step. Hormone analysis techniques using non-invasive sample collection have been vigorously developed for endangered species, from whom blood sampling is prohibited, or from species that are otherwise difficult to handle in a laboratory setting. Because there are interactions between glucocorticoids and thyroid hormones (T3 and T4), reducing the animal's "distress" during sample collection is imperative. Measurement of fecal T3 provides less sensitive, baseline information regarding thyroid function while permitting a non-invasive technique for more frequent sampling. We demonstrated that using a methanol extraction protocol produced the most reliable fecal T3 measurement in an enzyme-linked immunosorbent assay (ELISA). We found that during a thyroid hormone-treated state, fecal and plasma T3 measurements from mice are directly related, while during a methimazole-treated state, fecal and plasma T3 measurements from mice are inversely related. Fecal samples are a useful way to monitor thyroid hormone function in laboratory mice.

Anti-inflammatory effects of a methanol extract from Montanoa grandiflora DC. (Asteraceae) leaves on in vitro and in vivo models.

Montanoa grandiflora, a plant species native from Mexico to Central America, locally known as "Teresita" in Yucatán, México, is used to alleviate anxiety, rheumatism, and stomach issues. This study aims to investigate the anti-inflammatory properties of the methanol extract of Montanoa grandiflora leaves (MMG) in experimental models of inflammation. Gas chromatography-mass spectroscopy was used to characterize the MMG; cytotoxicity was assessed by MTT assay on murine macrophages and hemolysis assay. The in vitro anti-inflammatory activity was evaluated on LPS-stimulated murine macrophages by measuring of pro- and anti-inflammatory cytokines, NO and H2O2 release. The in vivo anti-inflammatory activity was evaluated using carrageenan-induced mouse paw edema, 12-O-tetradecanoylphorbol 13-acetate induced-ear edema, and 1-fluoro-2,4-dinitrobenzene induced-delayed-type hypersensitivity. In addition, the serum levels of prostaglandins and leukotrienes were assessed. The main compounds found in MMG were terpenes (i.e., β-caryophyllene, (-)-α-cubebene, alloaromadendrene, ( +)-δ-cadinene, β-eudesmol), alkaloid (( ±)-nor-β-hydrastine), cyclic polyol (quinic acid), carbohydrates and their derivatives, and fatty acids (octadecatrienoic acid and octadecanoic acid). MMG did not exhibit cytotoxic or hemolytic activity. However, it demonstrated in vitro anti-inflammatory effects by increasing the production of IL-10, decreasing the levels of TNF-α, IL-1β, IL-6, NO and H2O2. MMG significantly reduced carrageenan-induced paw edema, TPA-induced ear edema, and DNFB-induced delayed-type hypersensitivity in mice with effects comparable to those of standard drugs, as well as serum levels of prostaglandins and leukotrienes. The anti-inflammatory activity of MMG is associated with increased IL-10 levels and inhibiting inflammatory cell migration mechanisms, without causing cytotoxic or hemolytic damage in both in vitro and in vivo assays.

This study investigates the phytoconstituents of Myrica esculenta fruit extracts using various solvents, including n-hexane, dichloromethane, ethyl acetate, methanol, and water. Qualitative phytochemical analysis revealed the presence of several phytochemicals, with the highest concentration found in the methanol extract. The total phenolic (94.5±0.96 mg gallic acid equivalent (GAE)/g) and flavonoid (74.27±0.29 mg quercetin equivalent (QE)/g) contents were also highest in the methanol extract. Antioxidant activity was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic) acid (ABTS), and Ferric Reducing Antioxidant Power (FRAP) assays. The methanol extract exhibited superior antioxidant activity with DPPH and ABTS IC50 values of 22.27±0.98 μg/ml and 19.69±0.36 μg/ml, respectively, compared to ascorbic acid. FRAP activity was also highest in the methanol extract (87.125±0.33 mg Trolox equivalents (TE)/g). Gas Chromatography-Mass Spectrometry (GC-MS) analysis identified antioxidant compounds hexanedioic acid, bis(2-ethylhexyl) ester, methyl 11,12-octadecadienoate, and pentadecanoic acid. while Fourier Transform Infrared Spectroscopy (FTIR) analysis detected functional groups such as alkenes, ketones, esters, alcohols and carboxylic acids. These findings suggest that the methanolic extract of M. esculenta fruits is a rich source of natural antioxidants, making it suitable for pharmaceutical, health, and nutritional supplements aimed at enhancing overall health.

6-methyl-2-(3-nitrophenyl) imidazo [1,2-a] from Methanol Extract of Mangifera Indica as Potential Novel alpha-amylase inhibitor and Chemical Inducer of Glut 4 translocation: A Molecular Docking Computational Study

Diabetes, a chronic metabolic disorder characterised by hyperglycaemia has become a major global health concern, with an increasing prevalence worldwide (Mukhtar, Galalain &amp; Yunusa, 2020). Despite the availability of various anti-diabetic drugs, the search for natural remedies to manage diabetes has gained significant attention. Mangifera indica extracts have been studied for their anti-oxidant, anti-diabetic, lipid-lowering and anti-obesity potentials (Kumar et al., 2021). This study was designed to investigate the therapeutic effects of Mangifera indica methanol extract against Diabetes Mellitus, using in silico methods, Molecular docking simulations were performed to assess the binding affinities and interactions of the identified compounds from the Gas Chromatography/Mass Spectometry analysis result with key enzymes, proteins and hormones involved in glucose metabolism, such as alpha-amylase, insulin receptors, Glucose Transporter type 4 and Glucagon-like peptide 1. 6-methyl-2-(3-nitrophenyl) imidazo[1,2-a] pyridine had the highest binding affinity with Insulin receptors(-7.6kcal/mol), alpha amylase(-8.0kcal/mol) and Glucose transporter type 4(-8.5kcal/mol). Oxime-, methoxy-phenyl had the highest binding affinity with Glucagon-like peptide 1(-6.5kcal/mol). These findings suggest that mango leaves could serve as a source of natural anti-diabetic agent, which could lead to the development of new and effective treatments for diabetes. Further in vitro and in vivo studies are warranted to validate the bioactivity of these compounds and their mechanisms of action. Overall, this project contributes to the growing body of evidence supporting the use of in silico approaches for the discovery of novel antidiabetic agents from natural products.

Selective Cytotoxicity and Gene Expression Profiles in Response to Methanolic Extract of Phyllanthus amarus Extract against MCF-7 Breast Cancer Cells

Background Breast cancer, a malignant tumor, is the most common cancer type among women worldwide. Conventional chemotherapy treatments for breast cancer often cause adverse side effects in normal tissues and can lead to treatment failure. Plant-derived natural compounds offer an effective alternative with fewer side effects for cancer patients. Phyllanthus amarus is a medicinal plant widely distributed in China, India, and Brazil and reported to be used for the treatment of various types of cancer. Purpose This study was aimed to investigate the anticancer efficacy of methanolic extract of P. amarus against MCF-7 breast cancer cells. Methods We probed the anticancer activity in MCF-7 breast cancer cells by isolating the methanolic extract of P. amarus leaf extract (MEPA). The standard chemotherapy drug docetaxel is combined with MEPA to increase the drug efficacy. Moreover, the intracellular reactive oxygen species (ROS), alterations in mitochondrial membrane potential (MMP), nuclear condensation, and apoptotic activation were investigated in MCF-7 cells. Additionally, the customized PCR array comprising of cell cycle, apoptosis, mTOR, and JAK-STAT-related genes was studied during different MEPA treatments. Results In the MCF-7 breast cancer cells, the MEPA and docetaxel combination demonstrated strong cytotoxicity, with IC50 values of 45 and 2.6 µg/mL, respectively. MEPA and docetaxel together exhibited enhanced alterations in MMP and increased generation of ROS in MCF-7 cells. Furthermore, the combination of docetaxel with MEPA induces nuclear condensation and apoptotic cell death. During MEPA treatment, the gene expression profiles in MCF-7 cells were accessed. The JAK-STAT, mTOR signaling pathway, apoptosis, and cell growth-related genes were strongly affected by the dose-dependent administration of MEPA. Conclusion This study suggests that MEPA could be a useful alternative treatment for breast cancer. When combined with traditional chemotherapy, MEPA might offer better results with fewer side effects. More in vivo studies are needed to confirm MEPA’s effectiveness in animal models.
