Design of 5-fluorouracil (5-FU) loaded, folate conjugated peptide linked nanoparticles, a potential new drug carrier for selective targeting of tumor cells

biodistribution and gamma-scintigraphy showed good accumulation of peptide conjugated NPs in the tumor region. Therapeutic efficacy studies in B16F10 tumor xenografts also exhibited substantial tumor growth inhibition. The above studies reveal that folate peptide conjugation may facilitate the tumor-targeting approach of 5-FU-NPs.
