Cisplatin Nanoparticles for Folate Targeted Delivery in Ovarian Cancer: Study in SKOV-3 Cancer Cells

Tumor targeting of drug to specific site via use of folate is one the choicest method for enhancing specificity of Cisplatin. Chitosan was conjugated with folate via amino acylation method and Folate-chitosan-Cisplatin-nanoparticles (FA-CS-Cis-NP's) were prepared using ionotropic gelation method. Thus prepared nanoparticles were evaluated for various parameters such as particles size, % encapsulation efficiency, % drug release, cytotoxic assay, cellular uptake. The average particle size of nanoparticles was found to be 265 nm with encapsulation efficiency of 89.43%. The cumulative release of drug from dosage form was found to be 82.31% for 240 min. The higher level of intra-cellular accumulation of Cisplatin was found to be in case of FA-CS-Cis-NP's than conventional drug delivery when cultured with folate. The results indicate that targeting of FA-CSCis-NP's is possible with folate targeting and are proved as potential folate receptor positive tumor cell targeting drug delivery system.
