Synthesis and photodynamic properties of 5-ALA/g-C3N4@1 supramolecular photosensitizer with potential application in chronic hepatitis B treatment
The development of activatable nanoplatforms to enhance diagnostic and therapeutic performance while minimizing side effects is of great significance in treatment of chronic hepatitis B (CHB). Here, we report a novel nanomaterial composed of graphitic carbon nitride (g-C3N4) and 5-aminolevulinic acid (5-ALA), onto which our newly synthesized compound 1 is loaded, forming 5-ALA/g-C3N4@1. This nanomaterial is highly pH-sensitive and can rapidly degrade in mildly acidic environments, enabling the release of its loaded photosensitizer and compound 1, exhibiting characteristics such as fluorescence recovery and increased singlet oxygen generation. We evaluated the bioactivity of this novel composite material and explored its mechanisms of action. The effect of 5-ALA/g-C3N4@1 on the levels of HBV DNA, HBsAg and HBeAg was evaluated by treatment of HepG2.2.15 cells with the system. Our results suggest that the system can effectively inhibit HBV replication for the treatment of CHB. This work presents a novel photosensitive carrier with excellent biocompatibility and therapeutic efficacy, offering new insights into CHB research.
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.
