Abstract
Introduction: Silver nanoparticles (AgNPs) have gained significant attention in biomedical applications. Green synthesis methods provide an eco-friendly and cost-effective approach to AgNPs production, utilizing plant extracts as reducing and stabilizing agents. In this study, AgNPs were synthesized using the methanolic extract of Operculina turpethum.
Methodology: AgNPs were synthesized using O. turpethum extract, and their formation was confirmed through various analytical techniques. The antibacterial activity of both the crude extract and AgNPs was assessed against Staphylococcus aureus. Enzyme inhibition studies were conducted for urease, α-glucosidase, carbonic anhydrase II, and xanthine oxidase. Analgesic and sedative activities were evaluated through standard models.
Results: AgNPs exhibited an inhibition zone of 14 mm against S. aureus, greater than the crude extract (12 mm) but lower than Linezolid (25 mm). Enzyme inhibition studies revealed strong activity, particularly against urease (96.09% inhibition, IC5o = 25.65 ± 0.97 µg/mL). AgNPs demonstrated superior analgesic effects (81.98% at 10 mg/kg), comparable to diclofenac sodium (86.02%). Sedative effects were dose-dependent, reaching 35.09% at 10 mg/kg.
Discussion: The enhanced antibacterial activity of AgNPs suggests improved bioavailability and interaction with bacterial membranes. The strong enzyme inhibitory potential indicates their possible therapeutic role in enzyme-related disorders. The analgesic and sedative activity of AgNPs suggests their possible role in pain management agents and neuropharmacology. The results demonstrate the efficacy of green-synthesized AgNPs for biomedical applications.
Conclusion: Green synthesized AgNPs and their antibacterial, enzyme inhibitory, analgesic, and sedative properties suggest promising therapeutic applications. Further research should explore their mechanisms and in vivo safety for clinical applications.
期刊介绍：
The International Journal of Nanomedicine is a globally recognized journal that focuses on the applications of nanotechnology in the biomedical field. It is a peer-reviewed and open-access publication that covers diverse aspects of this rapidly evolving research area.
With its strong emphasis on the clinical potential of nanoparticles in disease diagnostics, prevention, and treatment, the journal aims to showcase cutting-edge research and development in the field.
