Abstract

Background: The current study aims to define the anti-anxiety properties of the leaves of Amaranthus cruentus Linn. and Rumex acetosa Linn. Methodology: Soxhlet extraction was used to extract the leaves of Rumex acetosa Linn and Amaranthus cruentus Linn. FTIR and GC-MS were used to investigate the fraction. The elevated plus maze test (EMPT) was used to assess the antianxiety property of methanolic extracts at 200 mg/kg and 400 mg/kg in Swiss albino mice. Results and discussion: Alkaloids, steroids, glycosides, amino acid flavonoids, carbohydrates, and phenolic tannins are found in both extracts. The percentage yields of petroleum ether, chloroform, and methanol extracts were 2.4%, 3.6%, and 10% for Amaranthus cruentus, and 2.1%, 3.2%, and 8% for Rumex acetosa, respectively. Amaranthus cruentus extracts were associated with significant increases (P < 0.05) in the amount of time and the number of entries in open arms. Open arm entries (p < 0.01) and time spent in the open arm (p < 0.01) were both increased by 200 mg/kg of Rumex acetosa Linn extract, while 400 mg/kg increased both of these variables (p < 0.001). Nevertheless, activity rises in tandem with the dosage of Rumex acetosa Linn extract. In EMPT, diazepam (2 mg/kg) significantly increased open arm entries (22.67) and time spent in open arms (3.273 min), while decreasing closed arm entries (6.33) and time spent in closed arms (1.582 min) compared to the control group, confirming its potent anxiolytic activity. Conclusion: The methanolic extracts of both plants exhibit significant anxiolytic properties.

Abstract

Background: Despite resistance to current tyrosine kinase inhibitors, which makes the epidermal growth factor receptor (EGFR) a recognized therapeutic target in breast cancer, there is a need for novel inhibitors. Quinoxaline compounds are a promising scaffold for next-generation EGFR inhibitors and exhibit favorable pharmacological properties. Methodology: Ten new amino quinoxaline derivatives (QN1–QN10) were systematically developed and assessed by a comprehensive in silico approach. Molecular docking was conducted on the EGFR tyrosine kinase domain (PDB ID: 4HJO) utilizing Glide XP, with erlotinib serving as the reference ligand. Drug-likeness, oral bioavailability, and synthetic accessibility were evaluated using SwissADME, whereas pkCSM predicted ADMET characteristics. The most effective candidate was subsequently corroborated by 100 ns molecular dynamics (MD) simulations utilizing GROMACS 2021.1, succeeded by MM-GBSA binding free energy assessments. Results and Discussion: According to docking data, QN8 proved the most promising inhibitor. It showed stable hydrogen bonding with key EGFR hinge residues (MET769 and ASP831) and a high binding affinity (−9.305 kcal/mol), comparable to erlotinib (−9.501 kcal/mol). Consistent RMSD and RMSF profiles from MD simulations corroborated the structural stability of the QN8–EGFR complex. According to MM-GBSA analysis, the van der Waals, lipophilic, and electrostatic contributions were the main drivers of the favorable binding free energy (-73.63 kcal/mol). Pharmacokinetic predictions showed adequate ADMET properties and good oral absorption. Conclusion: This exhaustive computational analysis highlights amino quinoxaline derivatives as promising leads for developing breast cancer drugs, identifying QN8 as a strong EGFR inhibitor with stable binding dynamics and favorable drug-like properties.

Abstract

Background: Rokshi is a traditional fermented rice beverage widely consumed by the Monpa tribe of Arunachal Pradesh, a Northeastern State in India, with cultural, nutritional, and biochemical significance. Methodology: Standard analytical methods were employed to determine pH, alcohol content, total acidity, viscosity, and antioxidant properties. Microbial count was assessed using the plate count method. Metabolite profiling and heavy metals analysis were conducted using GC-MS and ICP-OES, respectively. Results and Discussion: Rokshi were reported to be acidic and rich in metabolically important compounds. One-month-old Rokshi beverage showed increased alcohol content (7.54% v/v) as compared to fresh Rokshi beverage (2.59% v/v), with a pH of 4.10 (fresh), which decreased to 3.09 during storage. Total acidity increased from 0.58% to 0.78% after one month of storage. Total flavonoid and phenolic content were 0.205 mg QE/mL and 0.928 mg GAE/mL, respectively, with moderate antioxidant activity. Microbial load decreased in the starter culture (2.15 log CFU/mL) to 0.55 log CFU/mL in the final product. GC-MS analysis identified 28 metabolites, predominantly amino acids, sugars, organic acids, and alcohol. Heavy metals (Cd, Pb, Cr, Mn, Fe, Zn, Ni) were also detected, within the maximum permissible limit, and TTHQ values (<1) indicated no significant non-carcinogenic risk at 250 mL/day consumption. Conclusion: The current study showed that Rokshi holds promise for its nutritional and biochemical properties and has moderate antioxidant potential. The presence of a few biogenic amines and trace contaminants emphasizes the need for purification and further toxicological validation to ensure consumer safety and promote nutraceutical applications for commercial use as a functional fermented beverage.

Abstract

Background: According to epidemiological research, fluoride is a developmental neurotoxicant that lowers children's IQ scores. Fluoride induces oxidative stress in the brain, which can cause histological damage. This study aims to test the antioxidant potential of the methanolic extract of Pithecellobium dulce seeds. Methodology: By using different in vivo assays such as inhibition of DPPH activity in plasma, Glutathione Peroxidase (GSH-Px) activity in the brain, and histology of the cerebral cortex on days 1, 10, 20, and 30 with both Hematoxylin &Eosin and Cresyl violet stains. Results and Discussion: The methanolic extract of P dulce seeds significantly enhances GPx activity in a dose-dependent manner, effectively countering oxidative stress and providing neuroprotective benefits against fluoride-induced neurodegeneration. Results also showed the strong antioxidative potential of PDME, particularly in mitigating NaF-induced oxidative stress, as evidenced by sustained high DPPH radical-scavenging activity in the treated groups over time. An H&E histology study highlights the neuroprotective effects of PDME against NaF-induced neurodegeneration, demonstrating that PDME treatment significantly reduces neuronal loss and preserves cellular integrity, particularly at higher doses. Cresyl violet stain demonstrates that PDME has a neuroprotective effect against NaF-induced neurotoxicity, as evidenced by the preservation of neuronal morphology and Nissl substance. The study demonstrates that the methanolic extract of Pithecellobium dulce seeds exhibits significant antioxidant activity, effectively counteracting fluoride-induced neurotoxicity and preserving neuronal integrity by enhancing glutathione peroxidase activity and improving histological outcomes. Conclusion: These findings suggest that P. dulce may serve as a potential neuroprotective agent against fluoride-related cognitive impairments.

Abstract

Background: Antimicrobial resistance (AMR) is one of the most important threats to global public health, accelerating as conventional antibiotics lose efficacy. Pathogens such as Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Klebsiella pneumoniae use a variety of resistance mechanisms, including enzymatic drug degradation, efflux pump activation, and biofilm formation. The declining pipeline of newly approved antibiotics highlights the need for alternative and adjunctive therapeutic strategies. Methodology: This review critically summarizes studies that analyze polyherbal–antibiotic combinations and their synergistic antimicrobial effects. A systematic review of recent literature on the role of phytochemicals, including alkaloids, flavonoids, terpenoids, tannins, and polyphenolic compounds, in potentiating antibiotic efficacy and reducing antibiotic resistance was conducted. Results and Discussion: Integrative synergetic interactions were strongly evidenced between antibiotics and plant-derived phytochemicals. Epigallocatechin gallate (EGCG) synergizes with β-lactam for common resistant strains, and berberine inhibits efflux pumps to enhance antibiotic activity. A wide range of flavonoids and polyphenolic extracts have been reported to exhibit antimicrobial activity, with mechanisms involving membrane disruption, biofilm inhibition, and interference with quorum-sensing pathways, thereby promoting multifaceted action. Conclusion: Synergy between polyherbal treatment and antibiotics is an innovative approach to combat AMR and should be prioritized. This approach highlights various leads for future antimicrobial therapeutics by combining traditional ethnopharmacological knowledge with innovative pharmaceutical paradigms.

Abstract

Background: Tedizolid phosphate (TZP) is effective against Gram-positive pathogens. It is used most widely in skin infections. Currently, there is no development of emulgels with this novel antibiotic molecule. Hence, the current research focused on developing emulgels for effective topical antimicrobial action to overcome disadvantages associated with oral drug delivery. Methodology: The drug spectroscopic method was developed using a UV-visible spectrophotometer. The o/w emulsions were prepared and incorporated into a gel base to form an emulgel. The prepared emulgels were subjected to physicochemical, IR spectral, antimicrobial, and biophysical analysis. Results and Discussion: Physical examination revealed clear emulgel texture for all test formulations, with maximum spreadability and rheology for carbopol 934 compared to HPMCK 15 and sodium CMC bases. The optimized carbopol 934-based EF7 formulation showed 86% in vitro drug release and 73% ex vivo drug release in 12 hours, respectively. The FTIR studies clearly indicate no incompatibility among the drug and excipients. All physicochemical parameters confirmed controlled release, and FTIR studies confirmed no incompatibility. The optimized emulgel showed good bacterial growth inhibition, and pathological studies confirmed the absence of alteration of porcine ear skin structure. Conclusion: The results indicate that the optimized formulation is suitable for the treatment of acute skin infection.

Abstract

Background: Engeletin, a polyphenolic flavonoid, has demonstrated neuroprotective effects in experimental stroke models. However, the molecular interactome underlying its multitarget actions in ischemic stroke remains insufficiently characterized. Methodology: An integrated in silico workflow was applied to identify stroke-relevant targets of engeletin, combining target prediction, protein–protein interaction analysis, GO and KEGG pathway enrichment, and engeletin–target–pathway network construction. Network topology metrics were used to prioritize targets for downstream structure-based analyses. Docking was performed on short-listed targets, and selected protein–ligand complexes were further evaluated using molecular dynamics (MD) simulations to assess binding stability. In silico ADME profiling was conducted to contextualize translational considerations. Results and Discussion: Nineteen targets were identified through a confidence-driven overlap strategy. Degree-based network filtering short-listed 11 targets for docking. Multi-centrality convergence across protein–protein interaction and engeletin–target–pathway networks prioritized six influential hubs (PTGS2, CASP3, NOS2, MMP9, JAK2, and EGFR) implicated in inflammatory, apoptotic, and vascular regulation. Functional enrichment analyses highlighted interconnected inflammatory–immune, vascular, and metabolic stress pathways, with KEGG pathways interpreted as nominally enriched. Docking and MD analyses differentiated dynamically stable interactions from network-level co-modulated hubs, with engeletin exhibiting the most stable binding to NOS2 (inducible nitric oxide synthase). Conclusion: Integration of network pharmacology with structure-based analyses prioritizes NOS2-centered modulation and relaxin-associated vascular signaling as testable mechanisms for future experimental validation of engeletin in ischemic stroke.

Abstract

Background: Migraine is a debilitating neurological disorder that requires rapid and effective drug delivery to the brain. Conventional oral and parenteral therapies are associated with delayed onset of action, low patient compliance, limited central nervous system (CNS) bioavailability due to the blood-brain barrier (BBB), and hepatic first-pass metabolism. This study aimed to develop a thermoresponsive, mucoadhesive, nanoparticle-loaded nasal in situ gel to enhance brain delivery of an antimigraine drug. Methodology: Drug-loaded nanoparticles were prepared via ionic gelation and incorporated into a thermo-sensitive nasal in situ gel via the cold method. Results and Discussion: The optimized nanoparticle formulation (NP13) exhibited a small particle size (154.3 nm), acceptable polydispersity index (0.3485), positive zeta potential (22.79 mV), high entrapment efficiency (89.09%), drug loading (14.33%), and sustained drug release (90.26%). The developed in situ gel showed optimal pH (6.8), suitable gelling temperature (28–34 °C), viscosity (556 cp), entrapment efficiency (85%), drug content (95.82%), in vitro drug release (88.89 ± 0.98%), and ex vivo permeation (85.24 ± 0.67%) over 10 hours. Histopathological studies confirmed minimal nasal mucosal irritation compared to the drug solution and isopropyl alcohol. MTT assay results demonstrated concentration-dependent cytotoxicity, with SS-NPs ISG4 showing higher cell viability than the free drug, indicating reduced cytotoxicity due to nanoparticle encapsulation. Blank nanoparticles exhibited maximum cell survival, confirming carrier biocompatibility. Conclusion: The developed nanoparticle-loaded nasal in situ gel demonstrated promising safety, biocompatibility, and enhanced delivery potential, validating its suitability for intranasal migraine therapy.
