Abstract

|
Curcumin (CUR) nanomicelles were developed by solvent-evaporation method using Poly (lactic acid) (PLA) for the first time with Pluronic F127 (PF127) to produce CUR@PLA@PF127 nanomicelles. The X-ray diffraction (XRD) spectra confirmed the encapsulation of CUR into the produced nanomicelles (CUR@PLA@PF127). Fourier transform infrared spectroscopy (FTIR) analysis showed the interactions of CUR with PLA and PF127. Scanning electron microscope (SEM) and transmission electron microscope (TEM) analysis showed the formation of spherical shape of CUR@PLA@PF127 with a diameter around 130?160 nm. To investigate the anticancer effect of the encapsulated CUR, the activity of CUR@PLA@PF127 nanomicelles, free CUR and blank nanomicelles (PLA@PF127) were assayed against two cell lines in-vitro, human breast adenocarcinoma cells (MCF-7) and human breast skin fibroblast cells. The cytotoxicity assay of CUR@PLA@PF127 nanomicelles, revealed an IC50 value of 159.7 ± 1.36 μg/mL for MCF-7 cells which is much lower than that observed for free CUR. This result suggests that CUR@PLA@PF127 nanomicelles increased CUR potency due to improving its water solubility, resulting in longer release profile, and increasing antiproliferative effect on breast cancer cells (MCF-7). We anticipate that CUR@PLA@PF127 in drug delivery, improving drugs design and that the developed nanomicelles will be regarded one of the most promising nanocarriers for the treatment of breast cancer, and opening the door to future applications in cancer therapies.
