Abstract

This study aimed to prepare core–shell structural PLGA nanoparticles of astaxanthin (ASTA-PLGA@M) via micelle template for sustained release in vitro and long-term hepatoprotective effects in vivo. The morphology, mean particle size, zeta potential, polydispersity index (PDI), and drug loading efficiency of optimized formulation were investigated. Meanwhile, the physicochemical characterizations including X-ray diffraction (XRD) and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) of ASTA-PLGA@M were evaluated to prove the successful encapsulation of astaxanthin. The in vitro release of astaxanthin from ASTA-PLGA@M in four different media was sustained slowly for 120 h. An in vivo release study also demonstrated that ASTA-PLGA@M nanoparticles enhanced oral bioavailability significantly. In addition, the hepatoprotective effects of astaxanthin on oxidative stress (OS) accompanied by apoptosis in acute hepatic damage caused by carbon tetrachloride (CCl₄) in mice were investigated. ASTA-PLGA@M nanoparticles provide a clear elevating effect on the activity of SOD and inhibit the increase of MDA during acute liver damage caused by CCl4. Moreover, histopathological analysis was conducted to study the long-term hepatoprotective effects of ASTA-PLGA@M for further application of astaxanthin in functional food or clinical use.

期刊介绍： The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size. Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology. The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
