Previous studies have shown that αH is a potent anticancer agent that induces apoptosis in various types of cancer cells. However, its high toxicity and poor solubility in water limit its use in clinical applications. Therefore, the development of an effective delivery system for αH is highly desirable.Objectives/ObjectivesThe objective of this study is to develop a nanocarrier system based on acrylate resin for the efficient delivery of αH to cancer cells. The main goals are:1. Synthesis and characterization of αH-loaded acrylate resin nanoparticles2. Evaluation of the physicochemical properties and stability of the nanoparticles3. Assessment of the cytotoxicity and anti-cancer efficacy of the nanoparticles in vitro4. Investigation of the underlying mechanisms of αH-induced apoptosis in cancer cellsMethods/MethodologyαH-loaded acrylate resin nanoparticles will be synthesized by a nanoprecipitation method. The physicochemical properties, including particle size, zeta potential, morphology and drug loading capacity, will be characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) and high-performance liquid chromatography (HPLC). The stability of the nanoparticles will be assessed under different conditions, such as pH, temperature and storage time.The cytotoxicity and anti-cancer effects of the nanoparticles will be evaluated by MTT assay, colony formation assay and flow cytometry analysis. The underlying mechanisms of αH-induced apoptosis will be investigated by western blotting and immunofluorescence staining.精品文档---下载后可任意编辑Expected Results/Expected ResultsThe successful synthesis of αH-loaded acrylate resin nanoparticles with satisfactory physicochemical properties and high drug loading efficiency is expected. The nanoparticles are expected to exhibit enhanced cytotoxicity and anti-cancer efficacy compared to free αH due to improved solubility and bioavailability. The mechanism of αH-induced apoptosis in cancer cells will be clarified, which may provide a basis for further development of αH-based anti-cancer therapies.Conclusion/ConclusionThe development of an effective delivery system for αH is important for its clinical use as an anticancer agent. The proposed study aims to develop a nanocarrier system based on acrylate resin for the efficient delivery of αH to cancer cells. The results of this study will provide valuable insights into the development of novel drug delivery systems for the treatment of cancer.
