Synthesis, characterization, antioxidant and anticancer potential of Kalanchoe pinnata green synthesized silver nanoparticles targeting p53/MDM2 nexus in hepatic cancer: integrated in vitro and in silico study

The study describes green synthesis of silver nanoparticles (AgNPs) using Kalanchoe pinnata ethanolic leaf extract and characterizes them by DLS, TEM and FTIR, reporting an average hydrodynamic radius of ~4.74 nm and a zeta potential of +23.91 mV. In vitro HepG2 assays and in silico analysis showed increased ROS, apoptosis, and reduced cell viability, with suggested engagement of the p53/MDM2 nexus; GC–MS identified 33 bioactive compounds including β-amyrin.
