Characteristics and Cytotoxic Effects of Nano-Liposomal Paclitaxel on Gastric Cancer Cells.

Addressing both the initial treatment response and subsequent paclitaxel resistance is a pivotal concern. Nano drug delivery, an emerging approach, presents a cutting-edge alternative to conventional chemotherapy. This investigation synthesized PEGylated nanoparticles (NPs) via the Reverse Phase Evaporation technique for liposomal NPs. Characteristics such as zeta potential, size, drug release and polydispersity index (PDI) were subjected to evaluation. Subsequently, cytotoxicity assays were conducted on gastric cancer cells (AGS) following 24 and 48-hour incubation periods. In this study, the liposomal NPs had a zeta potential of -22 mV and a particle size of 285 nm. The Entrapment efficiency was determined as 41% that occurred physically. Additionally, the liposomal NPs demonstrated a high drug retention rate (39% remained after 72 hours), and they exhibited significantly increased cytotoxicity compared to the free drug, confirming their effectiveness as a suitable carrier for paclitaxel during both incubation periods (P<0.05). These findings collectively advocate the potential of liposomal NPs as promising contenders for effective nano-drug application in propelling chemotherapy forward.
