Abstract
- In order to improve curcumin’s low water-solubility and selective delivery to cancer, we reported ligand-mediated micelles based on a Y-shaped biotin-poly (ethylene glycol)–poly (epsilon-caprolactone) 2 (biotin-PEG–PCL 2 ) copolymer. Its structure was characterized by 1 H NMR. The blank and drug-loaded micelles obtained by way of thin-film hydration were characterized by dynamic light scattering, X-ray diffraction, infrared spectroscopy and hemolytic test. Curcumin was loaded into micelles with a high encapsulating efficiency (93.83%). Curcumin’s water-solubility was enhanced 170,400 times higher than free curcumin. Biotin-PEG–PCL 2 micelles showed slower drug release in vitro than H 2 N–PEG–PCL 2 micelles. In vitro cellular uptake and cytotoxicity tests showed that higher dosage of curcumin might overcome the effect of slow release on cytotoxicities because of its higher uptake induced by biotin, resulting in higher anticancer activities against MDA-MB-436 cells. In brief, Y-shaped biotin-PEG–PCL 2 is a promising delivery carrier for anticancer drug. [ABSTRACT FROM AUTHOR]
