The present study aims to develop and explore the use of PEGylated rapamycin (RP-MPEG) micelles for the treatment of gastric cancer. RP-MPEG was synthesized and characterized by using IR, H1 NMR and C13 NMR. RP-MPEG was prepared in the form of micelles and characterized by using field emission scanning electron microscopy, dynamic light scattering, zeta sizer, chromatographic analyses and photostability studies. The cytotoxicity studies of RP-MPEG micelles were conducted on specific CRL 1739 human gastric adenocarcinoma and CRL 1658 NIH-3T3 mouse embryonic fibroblast cell lines. RP-MPEG micelles showed the particle size distribution of 125±0.26 nm with narrow size distribution (polydispersity index 0.127±0.01). The surface charge of RP-MPEG micelles was found to be -12.3 mV showing enhanced anticancer activity against the CRL 1739 human gastric adenocarcinoma cell lines with an IC50 value of 1 mcg/ml.
