Aim of the investigation was to develop folate-functionalized lipid nanoemulsion (LNE) comprising chemo-radiotherapeutics for targeted delivery to nasopharyngeal carcinoma (NPC). Soy lecithin nanoemulsion of doxorubicin (Dox) and yittrium-90 (90Y) was prepared by nanoprecipitation using ultrasonic homogenization technique followed by folic acid conjugation. Nanoemulsion (Dox-LNE) was characterized as positively charged (zeta potential), spherical shape (transmission electron microscopy) nano-droplets of uniform size distribution (polydispersity index). No significant variation in parameters such as particle size, zeta potential, and polydispersity index was observed when the stability of Dox-LNE was assessed during long-term storage at room temperature and at 8000 rpm, 121°C temperature, and 5000 time dilution in water. In vitro release of Dox from Dox-LNE was observed to be controlled for at least 48 h. Folate decoration over Dox-LNE surface (FD-Dox-LNE) and incorporation of 90Y in FD-Dox-LNE (FD-Dox + 90Y-LNE) changed droplet size up to 50 nm; however, surface charge of Dox-LNE did not change significantly. FD-Dox + 90Y-LNE inhibited growth of cancerous cell line like CNE1 (folate receptor rich) in vitro and alleviated tumor volume in NPC-induced nude mice significantly as compared to Dox + 90Y-LNE. Massive necrosis and hemorrhage of CNE1 cells were observed by FD-Dox + 90Y-LNE (89.9%); however, inhibition of growth of nasal epithelial cells (RPMI 2650; folate deficient) by FD-Dox + 90Y-LNE and Dox + 90Y-LNE was observed to be 21.5 and 43.65%, respectively. The investigation highlights the vast utility of folate-decorated lipid emulsion in delivering chemo-radiotherapeutics to the specific NPC site. FD-Dox + 90Y-LNE might offer a cost-effective, safe, efficacious, and clinically pertinent option to the available therapeutics.
