Dimethylcurcumin-loaded methoxypolyethylene glycol-dimethylcurcumin conjugate nanoparticles: preparation, characterization and in vitro antitumor study
Dimethylcurcumin (DMC) is a synthetic curcuminoid which can enhance androgen receptor (AR) degradation to suppress AR-associated cancers. However, the poor water solubility and low bioavailability of DMC limit its biomedical applications. In our study, a water-soluble methoxypolyethylene glycol-dimethylcurcumin conjugate (cDMC-mPEG) was synthesized and further used for preparation of DMC loaded nanoparticles for effective DMC delivery. cDMC-mPEG was synthesized and characterized by proton nuclear magnetic resonance, fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, thermogravimetric analysis and differential scanning calorimetry. cDMC-mPEG self-assemble into nanoparticles in aqueous solution and can be used to encapsulate free DMC to form DMC-loaded cDMC-mPEG nanoparticles with small sizes and spherical morphology. The in vitro drug release study shows that DMC@cDMC-mPEG (15.3%) nanoparticles exhibit pH-triggered DMC release behaviors. The cellular uptake study shows that cDMC-mPEG and DMC@cDMC-mPEG (15.3%) nanoparticles exhibit enhanced cellular uptake as compared to free DMC, and DMC@cDMC-mPEG (15.3%) nanoparticles exhibit the highest cellular uptake amount. As a result, DMC@cDMC-mPEG (15.3%) nanoparticles exhibit enhanced cytotoxicity against 22Rv1 cells as compared to cDMC-mPEG and free DMC in in vitro antitumor effect study. The DMC@cDMC-mPEG (15.3%) nanoparticles developed in this work provide an effective nano-formulation for anti-prostate cancer DMC delivery.
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.
