Targeted delivery of essential oils of Salvia officinalis L to AGS cancer cells using PLA-spermine-PEG-FA

Abstract

The MTT test was used in this study to evaluate anticancer potential of Salvia officinalis L's essential oil on AGS cells. The results showed that the Salvia officinalis L's essential oil has high potential anticancer activity against AGS cells. To improve the solubility of the essential oil and its targeted administration to AGS cells, poly lactic acid-spermine-poly ethylene glycol-folic acid (PLA-Spermine-PEG-FA) (FPSP) was utilized. For this purpose, Salvia officinalis L's essential oil and silver nanoparticles were encapsulated into the PLA-Spermine-PEG-FA (FPSP) using the solvent diffusion technique. Then, using transmission electron microscope (TEM) and dynamic light scattering (DLS), respectively, morphology, zeta potential, as well as average particle size characteristics of the nanoparticles were evaluated. The FPSP/essential oil nanoparticles (FPSP/EO) were spherical in shape and had an average particle size of 200–300 nm. The mean particle dimensions for both PSP/silver/EO and FPSP/silver/EO nanoparticles assemblies are measured at 236.52 ± 22.64 nm and 248.95 ± 28.17 nm, respectively. The results showed that the zeta potential values for PSP/silver/EO and FPSP/silver/EO were −18.3 ± 0.7 mV and −20.6 ± 1.3 mV, respectively. The results of this test showed that FPSP/Silver/EO significantly reduced the percentage of AGS cell viability better than EO and PSP/Silver/EO. The best treatment in this experiment was FPSP/Silver/EO at a concentration of 50 μL/mL and time 72 h. The minimum value of IC50 in FPSP/Silver/EO was observed as 21.11 μL/mL in 72 h.
