An experiment was conducted to evaluate the effect of the age of a seedling and sources of nutrients on the growth and yield of sweet corn at SKUAST-K during Kharif-2020. The experiment was performed under a factorial arrangement in a randomized complete block design (RCBD) with three replications. Factor A was the age of the seedling with three levels, viz., 12-day-old seedlings, 22-day-old seedlings, and 32-day-old seedlings. Factor B was the source of nutrients with five levels, viz., control, recommended dose of fertilizer (RDF), 1/2 RDF + 12 t ha-1 farmyard manure, 1/2 RDF + 4 t ha-1 vermicompost, and 1/2 RDF + 2 t ha-1 poultry manure. The experiment was tested using variety Sugar-75 with a spacing of 75 × 20 cm2. The findings of this study indicated that the age of the seedling and sources of nutrients extended a significant influence on growth parameters, yield attributes, and yield of sweet corn. Significantly highest values for various growth parameters of sweet corn, viz., plant height, number of functional leaves, leaf area index (LAI), and dry matter accumulation from 30 days after transplanting up to the harvest, were noted by transplanting A2 seedlings (22 day old). A similar trend was observed for yield attributes and yield with higher values with transplanting A2 seedlings (22 day old). Plots fertilized with 1/2 RDF + 2 t ha-1 poultry manure registered a significantly higher plant height, leaf area index (LAI), dry matter accumulation, and number of functional leaves, which eventually resulted in a higher green cob yield and green fodder yield under the same treatment. Overall, this study indicated that among different ages of seedlings, transplanting A2 seedlings (22 day old) outperformed other seedling ages, and plots treated with 1/2 RDF + 2 t ha-1 poultry manure outperformed other treatments; a combination of both proved superior in realizing a higher yield and profitability with a benefit-cost ratio (BCR) of 6.57 under temperate climatic conditions.
Objectives: The present study was conducted to investigate the phytochemical analysis and demonstrate the nephroprotective potential of root extract of Glycyrrhiza glabra L. against cisplatin (CP) -induced nephrotoxicity in vitro and in vivo. Materials and Methods: The HPTLC analysis and UPLC-MS were carried out for standardizing and metabolite profiling of methanolic extract of roots of G. glabra (GGE). Further, in vitro studies were conducted in human embryonic kidney (HEK)-293 cells to evaluate the cytotoxicity and anti-oxidant potential of GGE with CP as a toxicant and ascorbic acid as standard. Also, in vivo nephroprotective potential at doses of 31.5, 63, and 126 mg/kg/day on CP (6 mg/kg, bw, IP) induced nephrotoxicity was evaluated on rodents. Results: Phytochemical analysis by HPTLC and UPLC-MS revealed the presence of glycyrrhizin, glabridin, and liquiritin along with other bioactive constituents. The in vitro assay of GGE showed significant (P<0.001 nephroprotective, cellular anti-oxidant potential and improvement in morphological changes induced by CP. Further, administration of CP caused significant (P<0.001) elevation in biochemical, inflammatory, oxidative stress, caspase-3, as well as histopathological changes in kidney tissue. Pre-treatment with GGE attenuated the elevated biochemical markers significantly, improved histopathological damage, and showed a comparable result to ascorbic acid and α-ketoanalogue. Conclusion: Present study concluded the nephroprotective potential of GGE which supports the traditional claim of G. glabra roots in various kidney and its related disorders. The nephroprotective activity may be attributed to its anti-oxidant, anti-inflammatory, and anti-apoptosis effects. Thus, it holds promising potential in management of nephrotoxicity.
Type 2 diabetes mellitus leads to metabolic impairment caused by insulin resistance and hyperglycemia, giving rise to chronic diabetic complications and poor disease prognosis. The heartwood of Pterocarpus marsupium has been used in Ayurveda for a long time, and we sought to find the actual mechanism(s) driving its antidiabetic potential. Methanol was used to prepare the extract using a Soxhlet extraction, and the identification of metabolites was performed by thin-layer chromatography (TLC) and ultraperformance-liquid chromatography and mass spectroscopy (UP-LCMS). The antioxidant potential of methanolic heartwood extract of Pterocarpus marsupium MHPM was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and a reducing power assay. The α-amylase and α-glucosidase enzyme inhibitory potential of MHPM were investigated for their antidiabetic activity against acarbose. TLC-MS-bioautography was performed to identify the compounds responsible for possible antioxidant and antidiabetic activities. Moreover, targeting protein tyrosine phosphatase 1B (PTP1B), a key regulator of insulin resistance, by identified metabolites from MHPM through molecular docking and all-atom molecular dynamics (MD) simulations was also undertaken, suggesting its potential as an antidiabetic herb. The IC50 of free-radical scavenging activity of MHPM against DPPH was 156.342 ± 10.70 µg/mL. Further, the IC50 values of MHPM in α-amylase and α-glucosidase enzymatic inhibitions were 158.663 ± 10.986 µg/mL and 180.21 ± 11.35 µg/mL, respectively. TLC-MS-bioautography identified four free radical scavenging metabolites, and vanillic acid identified by MS analysis showed both free radical scavenging activity and α-amylase inhibitory activity. Among the identified metabolites from MHPM, epicatechin showed significant PTP1B docking interactions, and its MD simulations revealed that PTP1B forms a stable protein-ligand complex with epicatechin throughout the progression, which indicates that epicatechin may be used as a promising scaffold in the development of the antidiabetic drug after isolation from Pterocarpus marsupium. Overall, these findings imply that Pterocarpus marsupium is a source of valuable metabolites that are accountable for its antioxidant and antidiabetic properties.
The lack of sufficient scientific evidence prompted the analytical investigation of nephroprotective potential of the silk extract of Zea mays L., which is traditionally and ethnomedicinally used for various disorders including kidney dysfunction. The present study was conducted to investigate the phytochemical analysis and demonstrate the nephroprotective potential of the methanolic silk extract of Z. mays L. using a rodent model. High-performance thin-layer chromatography (HPTLC) analysis was carried out to standardize the methanolic silk extract of Z. mays (ZME) using naringenin as a marker. The metabolite profiling of the ZME was carried out using ultrahigh-performance liquid chromatography mass spectrometry (UPLC-MS) on a monolithic capillary silica-based C18 column to identify bioactive compounds and for confirmation of the identified markers. Furthermore, for acute toxicity study, a single dose (2000 mg/kg bw) of the ZME was administered orally to Wistar rats. Also, nephrotoxicity was induced in Wistar rats by injecting diclofenac (DC) (50 mg/kg, bw, i.p.) at a single dose. The efficacy of the ZME as a nephroprotective agent was then evaluated at doses of 100, 200, and 400 mg/kg/day, bw, p.o. Furthermore, the kidney, liver, antioxidant, inflammatory, and apoptotic biochemical markers and histopathological and immunohistochemical alterations (caspase-3 and reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase-4 (NOX-4)) were evaluated. Phytochemical analysis by HPTLC and UPLC-MS revealed the presence of naringenin, vanillic acid, ferulic acid, gallic acid (GA), ellagic acid, quercetin, and morin, along with other bioactive constituents exhibiting multiple pharmacological properties. The acute toxicity study of the ZME showed no mortality or any clinical signs of toxicity through all the 14 days of the toxicity study at a dose of 2000 mg/kg. Also, administration of DC caused a significant elevation (P < 0.001) in kidney biochemical parameters and also caused oxidative, inflammatory, and apoptotic stress. Furthermore, DC also caused histopathological and immunohistochemical changes. Pretreatment with the ZME attenuated the elevated biochemical markers significantly at medium and high doses along with improvement in histopathological and immunohistochemical damages and showing comparable results to those of α-ketoanalogue. The present study verifies the traditional claims of Z. mays silk alleviating various kidney and related disorders by concluding the nephroprotective potential of the ZME. The nephroprotective activity of the ZME is attributed to the phytoconstituents present, acting as potent restoring antioxidants and preventing inflammatory and apoptotic cellular damages in rats. Thus, it holds promising potential in the management of nephrotoxicity.
Mulberry (Morus alba L.) is commonly cultivated in Asian countries as a traditional medicine and food supplement. Four Kashmiri Morus alba varieties (Zagtul, Chtattatual, Chattatual Zaingir, and Brentul Kashmir) were evaluated for their proximate composition, mineral content, total phenolic and flavonoid content, antioxidant potential, and antihyperglycemic activity. Furthermore, TLC-MS-bioautography was used for the identification of antioxidant and antidiabetic compounds in the best active extract. Lastly, UPLC-MS was employed for metabolomic profiling of the best variety of M. alba. Among all the varieties, the Zagtul variety was found to have the highest phenolic (71.10 ± 0.44 mg GAE/g DW) and flavonoid (53.22 ± 0.69 mg rutin/g DW) content. The highest antioxidant potential (DPPH) with an IC50 value of 107.88 ± 3.8 µg/mL was recorded for the Zagtul variety. Similarly, α-amylase and α-glucosidase inhibition for antidiabetic potential with IC50 74.76 ± 6.76 and 109.19 ± 5.78 µg/mL, respectively, was recorded in Zagtul variety. TLC-MS-bioautography for identification of bioactive compounds revealed the presence of chlorogenic acid for antioxidant potential and 1-deoxynojirimycin (DNJ) and syringic acid for antidiabetic potential. Further, bioactive compounds responsible for diverse functions of M. alba were confirmed by UPLC-MS in both negative and positive modes. However, major compounds in the Zagtul variety were identified as chlorogenic acid, moracin N, gallic acid, ferulic acid, morin, 1-deoxynojirimycin, and syringic acid. Hence, based on our findings, it can be concluded that M. alba leaves can be consumed as a promising dietary supplement and can be formulated as phytopharmaceutical for the management of various metabolic disorders.

The field experiment was conducted during Kharif season of 2020 at Agronomy farm of Faculty of Agriculture, Wadura, SKUAST-K to study the influence of age of seedling and sources of nutrients on phenology, yield and agrometeorological indices for sweet corn. The experiment included two factors viz. age of seedlings (12, 22 and 32 days old seedling) and sources of nutrients (control, RDF, 50 percent RDF + FYM @ 12 t ha-1, 50 percent RDF + vermi-compost @ 4 t ha-1 and 50 percent RDF + poultry manure @ 2 t ha-1) tested in RCBD with three replications. Transplanting 12 days old seedlings required maximum number of days to attain different phenological stages, thereby accumulated maximum heat units followed by 22 days old seedlings. While as transplanting 22 days old seedling recorded significantly highest HUE, HTUE, PTUE and HyTUE and consequently resulted in the highest green cob and biological yield compared to other ages of seedlings. Among various sources of nutrients, application of 50 per cent RDF + poultry manure @ 2 t ha-1 took maximum number of days to attain various phenophases thereby accumulated maximum heat units and registered highest HUE, HTUE, PTUE and HyTUE followed by application of 100 per cent RDF.
The use of herbal medicines and supplements in the last thirty years has increased enormously. Herbal medication has demonstrated promising and effective potential against various diseases. Herbal and phytoconstituent medications are gaining popularity globally and many people are adopting herbal remedies to deal with different health issues. The indiscriminate use of antibiotics, due to the development of antimicrobial resistance, poses an unprecedented problem for human civilization. Bacterial infections are difficult to cure because of the propensity of microbes to acquire resistance to a wide range of antimicrobial drugs. New compounds are being explored and quantified for possible antibacterial activity with little or no side effects. Researchers are investigating the range of therapeutic plants mentioned in Unani, Ayurveda, and Siddha around the globe. Known and commonly acclaimed global databases such as PubMed, Research Gate, Science Direct, Google Scholar were searched using different search strings such as Indian medicinal plants, multidrug resistance (MDR), thin layer chromatography (TLC), antimicrobials, and Synergism were used in diverse combinations to reclaim numerous citations associated with this area. Thus, the current review aims to shed a light on the information of medicinal plants as a potential foundation of herbal drugs and elucidate how synergism and TLC bioautography play a crucial role in finding antimicrobial compounds.

Breast cancer (BC) is mostly observed in women and is responsible for huge mortality in women subjects globally. Due to the continued development of drug resistance and other contributing factors, the scientific community needs to look for new alternatives, and drug repurposing is one of the best opportunities. Here we light upon the drug repurposing with a major focus on breast cancer. BC is a division of cancer known as the leading cause of death of 2.3 million women globally, with 685,000 fatalities. This number is steadily rising, necessitating the development of a treatment that can extend survival time. All available treatments for BC are very costly as well as show side effects. This unfulfilled requirement of the anti-cancer drugs ignited an enthusiasm for drug repositioning, which means finding out the anti-cancer use of already marketed drugs for other complications. With the advancement in proteomics, genomics, and computational approaches, the drug repurposing process hastens. So many drugs are repurposed for the BC, including alkylating agents, antimetabolite, anthracyclines, an aromatase inhibitor, mTOR, and many more. The drug resistance in breast cancer is rising, so reviewing how the challenges in breast cancer can be combated with drug repurposing. This paper provides the updated information on all the repurposed drugs candidates for breast cancer with the molecular mechanism responsible for their anti-tumor activity. Additionally, all the challenges that occur during the repurposing of the drugs are discussed.

Mulberry is a fast growing deciduous plant found in wide variety of climatic, topographical and soil conditions, and is widely distributed from temperate to subtropical regions. Due to presence of valuable phytochemical constituents, mulberry as a whole plant has been utilized as a functional food since long time. Mulberry fruits are difficult to preserve as they have relatively high water content. Therefore for proper utilization, different value-added products like syrups, squashes, teas, pestil sand köme, pekmez (turkuish by-products), yogurts, jams, jellies, wines, vinegar, breads, biscuits, parathas, and many more are made. In overseas, these value-added products are commercially sold and easily available, though in India, this versatile medicinal plant is still missing its identity at commercial and industrial scale. Leaves of mulberry are economically viable due to their important role in the sericulture industry since ancient times. Mulberries or its extracts exhibit excellent anti-microbial, anti-hyperglycaemic, anti-hyperlipidemic, anti-inflammatory, anti-cancer effects and is used to combat different acute and chronic diseases. Different parts of Morus species like fruits, leaves, twigs, and bark exhibit strong anti-tyrosinase inhibition activity that makes it a suitable candidate in cosmetic industries as a whitening agent. The current review provides a comprehensive discussion concerning the phytochemical constituents, functionality and nutraceutical potential of mulberry and as a common ingredient in various cosmetic products.
