Background In modern therapeutics, various human pathological disturbances were treated with the plant-based products. Waltheria indica Linn, a perennial herb, was commonly used in traditional medicine worldwide against various ailments such as cough, dysentery, diarrhea, bladder disorder, hemoptysis, inflammations, neuralgia, wounds, and ulcers. Main body The shrub was majorly distributed in tropical, subtropical regions and exists in many distinct local forms. Both the crude extracts and purified compounds from the whole plant and its parts showed wide pharmacological properties like antioxidant, analgesic, sedative, anti-bacterial, anti-fungal, and anti-parasitic. The phytochemical profile and traditional usage highlight the potency of the plant in the treatment of microbial infections and inflammatory diseases. Yet, additional studies are required for the confirmations of its traditional uses against other diseases. More detailed understanding of anti-cataract, anti-diabetics, asthma, anemia, and anti-cancer mechanism has to be explored. Though many research articles on the proposed plant are available, there has been a rising concern in the therapeutic property, especially on the alkaloids and flavonoids from this plant for drug design. Conclusion This article aims in a systematic and updated review on distribution, botany, traditional uses, phytocompounds, and relevant biological activities from each part of the plant. The information was collected from databases like PubMed, ScienceDirect, Web of Science, Google Scholar, books, dissertation, and reports via academic libraries that included more than 100 articles published since 1937. This ethnopharmacological study of the plant may create new insight into drug discovery to develop important novel leads against various biological targets.
Endophyte mediated nanoparticles fabrication were emerging as a new frontier in nanomedicines that produce high biocompatible and functionalized silver nanoparticles. In this study, silver nanoparticles were successfully biosynthesized from the extracellular extract of endophytic bacterium Pantoea anthophila isolated from the stem of Waltheria indica for the first time. The synthesized nanoparticles showed a strong absorption band at 410 nm in the UV–Visible range. The dynamic light scattering and zeta potential analysis indicated that the average particle size was 16 nm at 5.30 mV. FTIR spectrum displayed the presence of various functional groups at 3423.65, 1633.71, 1022.27, 607.58 cm −1 that stabilised the nanoparticle. X-ray diffraction peaks were conferred to 100, 200, 220 and 311 planes of a face centred cubic structure. TEM and SEM micrograph revealed the spherical-shaped, polycrystalline nature with the presence of elemental silver analysed by EDAX. Selected area electron diffraction also confirms the orientation of silver nanoparticles with X-ray diffraction analysis. Antimicrobial activity against 10 different human pathogenic bacteria and fungi showed a broad spectrum inhibition against both Gram-positive and Gram-negative bacteria. Among the bacterial pathogens, B. Subtilis exhibited low activity compared to other pathogens. C. albicans was greatly controlled than other fungal species. A strong free radical scavenging activity of silver nanoparticles with IC 50 values 31.29 ± 0.73, 19.83 ± 1.57, 35.64 ± 0.94, 42.07 ± 1.30, 29.70 ± 2.26, 29.10 ± 0.82, 36.80 ± 0.63 μg/ml was obtained in different antioxidant assays that were comparable to the reference. The study suggests that the silver nanoparticles can be biosynthesized from endophytic P. anthophila metabolites with significant therapeutic potential. With proper validation, the biosynthesized silver nanoparticles can be developed as a promising antiviral and anticancer drug candidate.
Endophyte mediated nanoparticles fabrication was emerging as a new frontier in nanomedicines that produce high biocompatible and functionalized silver nanoparticles. In this study, silver nanoparticles were successfully biosynthesized from the extracellular extract of endophytic bacterium Pantoea anthophila isolated from the stem of Waltheria indica for the first time. The synthesised nanoparticles were characterized by UV-Visible and Fourier Transform Infra-Red spectroscopy. The structural analysis is done by X-ray diffraction and the stability was studied by dynamic light scattering and particle size analyser. The size and shape were observed by Transmission Electron Microscope, Scanning Electron Microscope and Energy Dispersive X-Ray spectrum. Further, the nanoparticles were evaluated for antimicrobial and antioxidant properties. Synthesized nanoparticle showed a strong absorption band in the UV-Visible range at 410 nm. The average particle size was found to be 16.8 nm with spherical shaped, crystalline nature. Good zones of inhibition at various ranges were detected against a broad range of human pathogenic bacteria and fungi. A strong free radical scavenging activity of silver nanoparticles with IC50 values 30.75, 19.47, 34.59, 41.12, 27.24, 28.16, 36.21 µg/ml was obtained that was comparable to the reference. The study suggests that the silver nanoparticles can be biosynthesised from endophytic P. anthophila metabolites with significant therapeutic potential. With proper validation, the biosynthesised silver nanoparticles can be developed as a promising antiviral and anticancer drug candidate.
Yoga and Ayurveda are the unique sciences of antiquity. Both were developed and practiced in similar circumstances with similar objectives in the same land. Both are based on similar concept of human existence. Currently there is an emerging trend towards the holistic approach to the health related problems. The study focuses on the role of Netikarma in eye diseases based on Yoga and Ayurveda concepts. The study aims to reveal the facts on the benefits of Netikarma w.s.r to eye diseases based on the concepts explained in Yoga and Ayurveda Shastra. Ayurveda and Yoga both accepts Panchajnanendriyas i.e., sense organs. Eye is considered to be superior amongst the sense organs. In Astanga Hridaya it is said that “All efforts should be made to protect our eyes because for the blind man day and night are the same.” Yoga shastra describes six purificatory measures (Shat Karma) as the means of Nadi Shodhana. Among the Shatkarmas, Trataka and Neti are said to bring clear vision. Therefore this study is taken up to understand the mode of action of Netikarma in eye disorders.
Fish wastes include heads, intestines, fins, tails, and bones that are discarded in large quantity from fish processing industries. Substantial quantity of lipids and proteins can be extracted from these fish wastes to meet the dietary needs and to treat various ailments in humans. In the present study, the fish wastes of catla, rohu, and mixed fish wastes from Indian major carps are collected and analyzed for the fatty acid profile and protein content. The monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) obtained are analyzed for mutant B‐Raf kinase, a protooncoprotein inhibition using PATCHDOCK, and the best docked result is analyzed with PDBsum. The results showed that the concentration of saturated fatty acid was higher than that of MUFAs and PUFAs. The protein content was 0.58 mg/ml in Sample 1, 0.55 mg/ml in Sample 2, and 2.88 mg/ml in Sample 3. The docking study showed that MUFAs and PUFAs bound in the active site of the B‐Raf kinase domain with varied nonbonded interactions that may inhibit its activity, thus showing anticancerous properties. Practical applications Fishes are one of the major sources of balanced and nutritious diet for human beings. Huge tons of Indian major carps (IMCs) are discarded as wastes from fish processing industries and commercial markets that are rich in nutritive compounds like proteins, essential fatty acids, carbohydrates, vitamins, and so forth. These wastes can be recycled and reused for many pharmacological properties. Unsaturated fatty acids were found to have beneficial properties for humans. The selected MUFAs and PUFAs from fish wastes of IMCs showed inhibition of mutant B‐Raf kinase, a protein, associated with the activation of the Ras/Raf/MEK/ERK signaling pathway leading to cancer. Thus, these compounds may be used as cancer preventive agents and the study may lead to a novel approach to design drug molecules with nonbonded interactions in the protein–lipid interface.
