Abstract
In this project, a biocompatible block copolymer including poly ethylene glycol and poly caprolactone was synthesized using ring-opening reaction. Then, the copolymer was conjugated to folic acid using lysine as a linker. Also, curcumin (CUR) was used as a therapeutic anticancer agent. Nanoprecipitation method was used to prepare CUR-loaded polymeric micelles. Different methods including Fourier-transform infrared spectroscopy, transmission electron microscopy (TEM), and dynamic light scattering (DLS) were used to characterize the prepared nanocarriers (NCs). MTT assay and hemolysis assay were used to evaluate in vitro anticancer efficiency and biocompatibility of the prepared NCs, respectively. The results proved efficiency of NCs as a drug delivery system (DDS) in various aspects such as physicochemical properties and biocompatibility. Also, in vivo results showed that NCs did not show any severe weight loss and side effects on mice, and the anti-cancer study results of the CUR-loaded NCs proved that the conjugation of folic acid on the surface of NCs as a targeting agent could increase the therapeutic efficacy of CUR.
