Solar-Assisted Synthesis of Silver Nanoparticles from Amphilophium paniculatum (L.) Kunth: Unlocking Multi-Therapeutic Potential for Lung Cancer, Diabetes and Drug Resistant Infections through In vitro Studies and In silico Antidiabetic Evaluations
Abstract
This study contributes to develop and evaluate the biological applications of eco-friendly synthesized silver nanoparticles using Amphilophium paniculatum leaf ethanol extract via. solar irradiation method. The synthesized silver nanoparticles were characterized using UV, FTIR, FESEM and EDS. UV spectrum of silver nanoparticles showed the surface plasma resonance at 431 nm, which confirms the formation of silver nanoparticles. FTIR revealed the presence of functional groups in the extract which helps in the formation of silver nanoparticles. XRD pattern revealed the crystallite nature of nanoparticles. FESEM images showed spherical morphology with average size of 26-28 nm. Biological evaluations of silver nanoparticles exhibited higher antioxidant (IC50- 57.76μg/mL) compared to extract (IC50- 100.09μg/mL). The synthesized silver nanoparticles possess good antibacterial activities against clinical isolates such as Staphylococcus aureus (ZOI- 18mm) and Klebsiella pneumonia (ZOI- 14mm). Further, in vitro antidiabetic potential of silver nanoparticles revealed greater alpha amylase inhibition compared with standard drugs. The cytotoxic assessment on A549 cell lines revealed lower IC50 value (26.34 μg/mL) for silver nanoparticles, compared to extract (224 μg/mL), suggesting significant cytotoxicity. In silico screening of selected bioactive compounds from Amphilophium paniculatum evaluated for their physicochemical properties, toxicity and docking studies. Molecular docking…
