Description
Summary:Background Curcumin (CUR) is a bioactive compound with several proven pharmacological properties. However, the major limitation for therapeutic use of CUR is its low bioavailability. In this sense, an alternative to this question is the use of polymeric nanocapsules (NC) as drug/nutraceutical delivery systems. Thus, the aim of current study was to assess the effect of CUR-loaded NC and their different coatings in chick embryo model, evaluating angiogenic, teratogenic and oxidative stress parameters. Methods The physicochemical characterization of unloaded and loaded NC with different coatings: (U-NC (P80), U-NC (PEG), U-NC (EUD), U-NC (CS), CUR-NC (P80), CUR-NC (PEG), CUR-NC (EUD) and CUR-NC (CS)) were performed. After 9 days of incubation, eggs were treated (10 mL/kg eggs; via injection) with NC (unloaded and loaded with CUR) and CUR-solution. In sequence, hen’s egg test-chorioallantoic membrane (HET-CAM), angiogenic assay, external abnormalities, weight of embryos and oxidative stress markers (TBARS, NPSH, ROS and CAT) were analyzed. Results CUR-NC (P80, PEG, EUD and CS) treatments caused antiangiogenic and non-teratogenic effects in chick embryo model. Still, CUR-NC (P80), CUR-NC (PEG), CUR-NC (EUD) and CUR-NC (CS) did not alter markers of oxidative stress (TBARS, NPSH, CAT) studied. Only CUR-NC (EUD) caused increase in ROS levels. Conclusion Wherefore, these findings of present study represent a advance in research of drug/nutraceutical delivery systems.
