RESUMO

OBJECTIVES: Vitamin B7(biotin) is not synthesized in our body and is retrieved from some food products like eggs, liver, pork and leafy vegetables and as well as microbes of gut. Deficiency of biotin majorly leads to loss of hair, rashes over skin, lethargy and seizures. It is noted that biotin is an anti-oxidant and negates free radical effects. Biotin is also involved in carbon dioxide metabolism and it might alter seizure threshold. Studies also suggest its effect on lipid metabolism as well. So, the primary objective of this study was to assess the efficacy of biotin in maximal electric shock (MES) induced generalized tonic-clonic seizures (GTCS) and pentylenetetrazole (PTZ) induced absence seizures. The secondary objective is to study the effect of combined treatment of biotin and sodium valproate on seizures as well as plasma lipid profile in rats. METHODS: In our study 30 albino Wistar rats each were used in MES and PTZ model respectively. 30 rats were divided equally into following groups: I - distilled water (negative control) II - distilled water (positive control) III - sodium valproate (300 mg/kg) IV - biotin (10 mg/kg/day) V - biotin (10 mg/kg) + sodium valproate (150 mg/kg). RESULTS: We observed that the tonic hind limb extension was significantly reduced in the treatment group in MES model. Nitric oxide levels were also seen raised in combination group in MES model and all the treated groups in PTZ model. Biotin treated group showed increased high-density lipoproteins and reduced low density lipoproteins and triglycerides. CONCLUSIONS: Biotin had an additive effect to sodium valproate in both the models of epilepsy in rats. Further, it was also able to counteract hyperlipidemia cause by sodium valproate.

RESUMO

Coronopus didymus (Brassicaceae) commonly known as lesser swine cress has been reported to be used for its pharmacological activities. This study aimed to evaluate the medicinal potential of C. didymus extracts against cancer, diabetes, infectious bacteria and oxidative stress and the identification of bioactive compounds present in these extracts. The effects of using different solvents for the extraction of C. didymus on the contents of major polyphenols and biological activities were investigated. Plant sample was shade dried, ground to a fine powder, and then soaked in pure acetone, ethanol and methanol. The highest contents of major polyphenols were found in methanol-based extract, i.e., chlorogenic acid, HB acid, kaempferol, ferulic acid, quercetin and benzoic acid with 305.02, 12.42, 11.5, 23.33, 975.7 and 428 mg/g of dry weight, respectively, followed by ethanol- and acetone-based extracts. The methanol-based extract also resulted in the highest antioxidant activities (56.76%), whereas the highest antiproliferative (76.36) and alpha glucosidase inhabitation (96.65) were demonstrated in ethanol-based extracts. No antibacterial property of C. didymus was observed against all the tested strains of bacteria. Further studies should be focused on the identification of specific bioactive compounds responsible for pharmacological activities.

RESUMO

In the current decade, nanoparticles are synthesized using solvents that are environmentally friendly. A number of nanoparticles have been synthesized at room temperature using water as a solvent, such as gold (Au) and silver (Ag) nanoparticles. As part of nanotechnology, nanoparticles are synthesized through biological processes. Biological methods are the preferred method for the synthesis of inorganic nanoparticles (AgNPs) as a result of their simple and non-hazardous nature. Nanoparticles of silver are used in a variety of applications, including catalysts, spectrally selective coatings for solar absorption, optical objectives, pharmaceutical constituents, and chemical and biological sensing. Antimicrobial agents are among the top uses of silver nanoparticles. In the current study, silver nanoparticles were biologically manufactured through Madhuca longifolia, and their antibacterial activity against pathogenic microorganisms, anticancer, anti-inflammatory, and antioxidant activities were assessed. UV-Vis spectroscopy, XRD (X-ray diffraction), transmission electron microscopy, Zeta Potential, and FTIR were used to characterize silver nanoparticles. The current work describes a cheap and environmentally friendly method to synthesize silver nanoparticles from silver nitrate solution by using plant crude extract as a reducing agent.

RESUMO

Wendlandia tinctoria var. grandis (Roxb.) DC. (Family: Rubiaceae) is a semi-evergreen shrub distributed over tropical and subtropical Asia. The present research intended to explore the pharmacological potential of the stem extract of W. tinctoria, focusing on the antioxidant, hypoglycemic, and antidiarrheal properties, and to isolate various secondary metabolites as mediators of such activities. A total of eight phenolic compounds were isolated from the dichloromethane soluble fraction of the stem extract of this plant, which were characterized by electrospray ionization (ESI) mass spectrometric and 1H NMR spectroscopic data as liquiritigenin (1), naringenin (2), apigenin (3), kaempferol (4), glabridin (5), ferulic acid (6), 4-hydroxybenzoic acid (7), and 4-hydroxybenzaldehyde (8). The dichloromethane soluble fraction exhibited the highest phenolic content (289.87 ± 0.47 mg of GAE/g of dried extract) and the highest scavenging activity (IC50 = 18.83 ± 0.07 µg/mL) against the DPPH free radical. All of the isolated compounds, except 4-hydroxybenzaldehyde, exerted a higher antioxidant effect (IC50 = 6.20 ± 0.10 to 16.11 ± 0.02 µg/mL) than the standard butylated hydroxytoluene (BHT) (IC50 = 17.09 ± 0.01 µg/mL). Significant hypoglycemic and antidiarrheal activities of the methanolic crude extract at both doses (200 mg/kg bw and 400 mg/kg bw) were observed in a time-dependent manner. Furthermore, the computational modeling study supported the current in vitro and in vivo findings, and the isolated constituents had a higher or comparable binding affinity for glutathione reductase and urase oxidase enzymes, glucose transporter 3 (GLUT 3), and kappa-opioid receptor, inferring potential antioxidant, hypoglycemic, and antidiarrheal properties, respectively. This is the first report of all of these phenolic compounds being isolated from this plant species and even the first demonstration of the plant stem extract's antioxidant, hypoglycemic, and antidiarrheal potentials. According to the current findings, the W. tinctoria stem could be a potential natural remedy for treating oxidative stress, hyperglycemia, and diarrhea. Nevertheless, further extensive investigation is crucial for thorough phytochemical screening and determining the precise mechanisms of action of the plant-derived bioactive metabolites against broad-spectrum molecular targets.

RESUMO

Medicinal plants have been crucial in treating various chronic ailments since ancient times. The objective of this study was to evaluate in vitro pharmacological properties of petroleum ether, chloroform, and ethyl acetate soluble fractions of ethanolic extract (leaf, bark, and root) of Heritiera fomes Buch. Ham., including the phytochemical screening of the plant. Thrombolytic and antiarthritic properties were assessed through the clot lysis and protein denaturation experimental method, correspondingly. Anthelmintic and insecticidal activities were studied against Pheretima posthuma and Tribolium castaneum, respectively. The phytochemical analysis exhibited numerous active phytochemicals in different solvent fractions. In thrombolytic investigation, among all crude extracts, ethanolic leaf extract showed the highest 33.12 ± 7.52% clot lysis as compared to standard streptokinase (67.77 ± 9.78%). In antiarthritic assay, all the tested samples exhibited noteworthy protein denaturation in dose-dependent manner (100-500 µg/mL), whereas the utmost percentage inhibition was noticed for chloroform extract of roots (63.28 ± 5.96% at 500 µg/mL). All crude extracts exhibited a significant anthelmintic activity in different concentrations (25-75 mg/mL) and revealed paralysis and death of earthworms in comparison with albendazole; ethanolic extract of the bark was found to be more potent at the highest dose. For the insecticidal test, ethanolic extract of the leaf showed the utmost mortality rate (73%). The outcomes of the investigation confirmed the potential thrombolytic, antiarthritic, anthelmintic, and insecticidal activities of the different extracts of H. fomes, and hence, advanced studies on the isolation and identification of active phytocompounds are highly needed for new drug development.

RESUMO

Habb-e-Suranjan (HES), an Unani formulation, has been studied for its anti-inflammatory properties in both in vitro and in vivo experiments. HES is recommended for arthritis, gout, and joint pain. The current endeavor is an attempt to put it to the test and verify its efficacy scientifically. It was tested for DPPH, hydroxyl, and nitric oxide scavenging activities. It was shown that HES had the greatest TAC and FRAC values when compared to catechin and ascorbic acid. HES exhibited DPPH and hydroxyl radical scavenging activity that was dose-dependent. Incubation of sodium nitroprusside solutions in PBS at 25°C for 150 min resulted in the production of nitric oxide. Nitric oxide production was effectively decreased by HES. Anti-inflammatory medications boosted the migration of PMN cells toward the chemoattractant FMLP in an agarose experiment of PMN chemotaxis. In carrageenan-induced rat paw edema, in the HES-treated group, paw thickness was 3.021 ± 0.084 at t = 0, but it showed an increase in paw inflammation after one hour, i.e., 3.195 ± 0.082 cm which again showed a decrease in paw thickness up to 4th hour, i.e., 3.018 ± 0.078, 2.98 ± 0.032, and 2.684 ± 0.061 at t = 2, 3, and 4, respectively. It showed again getting back to the normal thickness of paw at t = 24 hrs, i.e., 3.029 ± 0.118 cm. It is concluded that the formulation is potent enough and can be used effectively for the treatment of inflammation and associated health issues. Moreover, there is much scope to evaluate its effectiveness using different in vitro and in vivo models.

RESUMO

Medicinal plants have considerable potential as antimicrobial agents due to the presence of secondary metabolites. This comprehensive overview aims to summarize the classification, morphology, and ethnobotanical uses of Euphorbia neriifolia L. and its derived phytochemicals with the recent updates on the pharmacological properties against emerging infectious diseases, mainly focusing on bacterial, viral, fungal, and parasitic infections. The data were collected from electronic databases, including Google Scholar, PubMed, Semantic Scholar, ScienceDirect, and SpringerLink by utilizing several keywords like 'Euphorbia neriifolia', 'phytoconstituents', 'traditional uses', 'ethnopharmacological uses', 'infectious diseases', 'molecular mechanisms', 'COVID-19', 'bacterial infection', 'viral infection', etc. The results related to the antimicrobial actions of these plant extracts and their derived phytochemicals were carefully reviewed and summarized. Euphol, monohydroxy triterpene, nerifoliol, taraxerol, ß-amyrin, glut-5-(10)-en-1-one, neriifolione, and cycloartenol are the leading secondary metabolites reported in phytochemical investigations. These chemicals have been shown to possess a wide spectrum of biological functions. Different extracts of E. neriifolia exerted antimicrobial activities against various pathogens to different extents. Moreover, major phytoconstituents present in this plant, such as quercetin, rutin, friedelin, taraxerol, epitaraxerol, taraxeryl acetate, 3ß-friedelanol, 3ß-acetoxy friedelane, 3ß-simiarenol, afzelin, 24-methylene cycloarenol, ingenol triacetate, and ß-amyrin, showed significant antimicrobial activities against various pathogens that are responsible for emerging infectious diseases. This plant and the phytoconstituents, such as flavonoids, monoterpenoids, diterpenoids, triterpenoids, and alkaloids, have been found to have significant antimicrobial properties. The current evidence suggests that they might be used as leads in the development of more effective drugs to treat emerging infectious diseases, including the 2019 coronavirus disease (COVID-19).

RESUMO

Plants generally secrete secondary metabolites in response to stress. These secondary metabolites are very useful for humankind as they possess a wide range of therapeutic activities. Secondary metabolites produced by plants include alkaloids, flavonoids, terpenoids, and steroids. Flavonoids are one of the classes of secondary metabolites of plants found mainly in edible plant parts such as fruits, vegetables, stems, grains, and bark. They are synthesized by the phenylpropanoid pathway. Flavonoids possess antibacterial, antiviral, antioxidant, anti-inflammatory, antimutagenic, and anticarcinogenic properties. Due to their various therapeutic applications, various pharmaceutical companies have exploited different plants for the production of flavonoids. To overcome this situation, various biotechnological strategies have been incorporated to improve the production of different types of flavonoids. In this review, we have highlighted the various types of flavonoids, their biosynthesis, properties, and different strategies to enhance the production of flavonoids.

RESUMO

The field of nanotechnology is concerned with the creation and application of materials having a nanoscale spatial dimensioning. Having a considerable surface area to volume ratio, nanoparticles have particularly unique properties. Several chemical and physical strategies have been used to prepare zinc oxide nanoparticles (ZnO-NPs). Still, biological methods using green or natural routes in various underlying substances (e.g., plant extracts, enzymes, and microorganisms) can be more environmentally friendly and cost-effective than chemical and/or physical methods in the long run. ZnO-NPs are now being studied as antibacterial agents in nanoscale and microscale formulations. The purpose of this study is to analyze the prevalent traditional method of generating ZnO-NPs, as well as its harmful side effects, and how it might be addressed utilizing an eco-friendly green approach. The study's primary focus is on the potential biomedical applications of green synthesized ZnO-NPs. Biocompatibility and biomedical qualities have been improved in green-synthesized ZnO-NPs over their traditionally produced counterparts, making them excellent antibacterial and cancer-fighting drugs. Additionally, these ZnO-NPs are beneficial when combined with the healing processes of wounds and biosensing components to trace small portions of biomarkers linked with various disorders. It has also been discovered that ZnO-NPs can distribute and sense drugs. Green-synthesized ZnO-NPs are compared to traditionally synthesized ones in this review, which shows that they have outstanding potential as a potent biological agent, as well as related hazardous properties.

RESUMO

Lepidagathis hyalina Nees is an ethnomedicinally potential Asian herb, locally used to treat cardiovascular diseases and coughs. The study was intended to evaluate qualitative and quantitative investigation to ensure numerous pharmacological properties of methanol extracts of L. hyalina Ness root (MELHR). MELHR manifested strong radical scavenging activity in the reducing power and DPPH (1, 1-diphenyl-2-picrylhydrazyl) assays, and phenol and flavonoid in the quantitative assays. In the study of the thrombolytic assay, MELHR showed moderate explicit percentage of clot lysis (29.39 ± 1.40%) with moderate (135.35 µg/mL) toxic properties. The in vitro anti-inflammatory activity was evaluated by the inhibition of hypotonicity-induced RBC hemolysis, whereas the plant extract exhibited a significant (pp ˂ 0.005) dose-dependent inhibition and the highest inhibition was found 55.01 ± 3.22% at 1000 µg/mL concentration. Moreover, the MELHR also showed significant (p < 0.005) dose-dependent potentiality on protein denaturation which is considered as antiarthritic activity, and the peak inhibition was found significant (71.97 ± 2.71%) at 1000 µg/mL concentration. MELHR also exhibited the dose-dependent and statistically significant anthelmintic potential on aquarium worm (Tubifex tubifex). So, the present investigation suggests that L. hyalina could be the best choice for the management of cardiovascular, inflammation, arthritis, and anthelmintic diseases. Further investigation should be necessary to determine behind the mechanism of bioactivity and therapeutic potential of this plant.

RESUMO

Cancer is recognized as one of the main causes of mortality worldwide by the World Health Organization. The high cost of currently available cancer therapy and certain limitations of current treatment make it necessary to search for novel, cost-effective, and efficient methods of cancer treatment. Therefore, in the current investigation, sixty-two compounds from five medicinal plants (Tinospora cordifolia, Ocimum tenuiflorum, Podophyllum hexandrum, Andrographis paniculata, and Beta vulgaris) and two proteins that are associated with breast cancer, i.e., HER4/ErbB4 kinase and ERα were selected. Selected compounds were screened using Lipinski's rule, which resulted in eighteen molecules being ruled out. The remaining forty-four compounds were then taken forward for docking studies followed by molecular dynamics studies of the best screened complexes. Results showed that isocolumbin, isopropylideneandrographolide, and 14-acetylandrographolide were potential lead compounds against the selected breast cancer receptors. Furthermore, in vitro studies are required to confirm the efficacy of the lead compounds.

RESUMO

Diseases with a significant loss of neurons, structurally and functionally are termed as neurodegenerative diseases. Due to the present therapeutic interventions and progressive nature of diseases, a variety of side effects have risen up, thus leading the patients to go for an alternative medication. The role of medicinal plants in such cases has been beneficial because of their exhibition via different cellular and molecular mechanisms. Alleviation in inflammatory responses, suppression of the functionary aspect of pro-inflammatory cytokines like a tumor, improvement in antioxidative properties is among few neuroprotective mechanisms of traditional plants. Variation in transcription and transduction pathways plays a vital role in the preventive measures of plants in such diseases. Neurodegenerative diseases are generally caused by the depletion of proteins, oxidative and inflammatory stress, environmental changes and so on, with aging being the most important cause. Natural compounds can be used in order to treat neurodegenerative diseases Medicinal plants such as Ginseng, Withania somnifera, Bacopa monnieri, Ginkgo biloba, etc. are some of the medicinal plants for the prevention of neurological symptoms. This review deals with the use of different medicinal plants for the prevention of neurodegenerative diseases.

RESUMO

With the COVID-19 pandemic still wreaking havoc worldwide, new variants being discovered every month in some parts of the globe due to the mutating nature of the virus. There is no specific solution for this highly transmissible disease. In search of a lead molecule for the discovery and development of drug, extensive research is being conducted throughout the world. Many synthetic drugs are already in clinical trials and some are utilized for the treatment of this viral infection. Apart from synthetic drugs, phytocompounds from plants act as a potential drug candidate which can inhibit the growth of virus and thus able to prevent the viral infection. In this study, 26 ligands (bioactive compounds) from Boswellia serrata (an important medicinal plant) were tested against SARS-CoV-2 by using computational method. Selected ligands were shortlisted using Lipinski's rule and then subjected to molecular docking against one of the main proteins of SARS-CoV-2, i.e., Mpro. Out of these compounds, Euphane, Ursane, α-Amyrin, Phytosterols, and 2,3-Dihydroxyurs-12-en-28-oic acid were potential to inhibit the Mpro activity with binding energies of - 10.47 kcal/mol, - 10.41 kcal/mol, - 9.99 kcal/mol, - 9.94 kcal/mol and - 9.72 kcal/mol respectively. A comparative study was performed using the best five ligands against four possible drug targets of SARS-CoV-2. It was found that Euphane showed highest negative binding energy against all the four crucial targets of SARS-CoV-2. Further, in-vitro experimentation is required to validate the use of Euphane as a potent drug against SARS-CoV-2.

RESUMO

Cancer is a deadly disease, which has significantly increased in both developed and developing nations. Treatment of cancer utilizing radiotherapy or chemotherapy actuates a few issues which incorporate spewing, sickness, unpalatable reactions, and so forth. In this specific situation, an alternative drug source, which can effectively treat cancer is of prime importance. Products that are obtained from plant sources are utilized for the treatment of various diseases due to their non-harmful nature. Medicinal plants contain different bioactive compounds, which possess an important role in the prevention of different diseases such as cancer. Plumbagin is a bioactive compound, which is mainly present in Plumbaginaceae family and has been explored for its anticancer activity. Plumbagin basically inactivates the Akt/NF-kB, MMP-9 and VEGF pathways that are essential for cancer cell development. Therefore, it is important to review the role of plumbagin in different cancer cells in order to find an alternative drug to overcome this disease. The present review provides a summary of anticancer activity of plumbagin in various cancers and its mode of action.

RESUMO

Medicinal plants produce a diverse group of phytocompounds like anthraquinones, alkaloids, anthocyanins, flavonoids, saponins, and terpenes which are used in pharmaceutical, perfume, cosmetics, dye and flavor industries. Commercial source of these metabolites is field-grown plants, which are generally influenced by seasonal changes. Biotechnology possesses a significant role in production of high-value secondary metabolites. By incorporating biotechnological methods, it is feasible to manage biosynthetic pathways of the plant to enhance phytocompound production that is of pharmaceutical interest. Plant cell suspension, shoot, adventitious root and hairy root culture are considered as alternative methods for important bioactive compound production. These methods are controllable, sustainable and overcome several inconveniences for large scale secondary metabolites production. At present research on hairy root culture for valuable bioactive compound production has gained a lot of attention. Agrobacterium rhizogenes is an agent which causes hairy root disease in a plant and this leads to the neoplastic growth of root which is characterized by higher growth rate and genetic stability. Various studies explore the hairy root culture for production of a wide range of bioactive compounds. Scale-up of hairy root culture using bioreactors has provided an opportunity to enhance bioactive compound production at the commercial level. The present review discusses the role of hairy root culture in the production of valuable bioactive compounds, the effect of culture parameters on bioactive compound production and bioreactor applications.

RESUMO

Ischemic stroke is one of the major causes of deaths around the world. Prominent changes, including emotional, cognitive, and behavioral, in the Central Nervous System (CNS) are observable during the recovery phase of a stroke. Brain ischemia affects a large portion of patients across the world with permanent disability or death. During the ischemic stroke onset, apart from inducing brain damage, existing microglial cells, immune cells, inflammatory factors such as chemokines and cytokines affect the process of brain repair. For the reduction of this damage, there is a need to understand the basic mechanisms involved in ischemic stroke and how to repair it with the help of efficient therapeutic strategies. At present, anti-inflammatory therapeutic measures are the most potent alternatives for its prevention. Due to the existence of various drawbacks in this therapy, newer remedial measures are required to overcome this situation. The most economically efficient treatment option, with lesser side effects, is the utilization of medicinal plants. Worldwide, plants are utilized for the treatment of various diseases such as bacterial infections, skin disorders, cancer, asthma, respiratory problems, etc. Various medicinal plants have been administered over a long period, and they have been proven to cure ischemic strokes. Therefore, in this review, an overview of various plants and their phytocompounds, which are responsible for the treatment of ischemic stroke, has been discussed.

RESUMO

With the emergence and evolution of bacterial strains, it is now becoming difficult for pharmaceutical industries to provide remedies required for the betterment of mankind. Continuous exposure with available medication leads to the development of new strains with a significant amount of resistance, due to which pharmaceutical industries are facing various challenges. Antimicrobial resistance is the phenomenon causing a challenge in new drug development through conventional methods. Therefore, the requirement of alternative medicine is in high demand. Recently, allopathic medicines have seen a disinterest and people are preferring natural solutions due to their fewer side effects comparable to conventional medicine. Worldwide plants are utilized for various disease treatments such as bacterial infection, skin disorders, cancer, asthma, respiratory problems, etc. The presence of a wide range of phytocompounds in different plants provides an alternative to the pharmaceutical industries to counter the problem of bacterial infections. Different plants contain various phytochemicals that possess numerous therapeutic activities and provide a remedy to suppress various bacterial strains. Therefore, in this review, an overview of various plants and their phytocompounds which are responsible for antibacterial activity has been discussed.
