High Drug Loading

Drug delivery carriers with a high drug loading capacity and biocompatibility, especially for controlled drug release, are urgently needed due to the side effects and frequent dose in the traditional therapeutic method. Guided by nanomaterials, we have successfully synthesized zirconium-based metal−organic frameworks, Zr-TCPP (TCPP: tetrakis (4-carboxyphenyl) porphyrin), namely, PCN-222, which is synthesized by solvothermal method. And it has been designed as a drug delivery system (DDS) with a high drug loading of 38.77 wt%. In our work, PCN-222 has achieved pH-sensitive drug release and showed comprehensive SEM, TEM, PXRD, DSC, FTIR, and N2 adsorption-desorption. The low cytotoxicity and good biocompatibility of PCN-222 were certificated by the in vitro results from an MTT assay, DAPI staining, and Annexin V/PI double-staining even cultivated L02 cells and HepG2 cells for 48h. Furthermore, Oridonin, a commonly used cancer chemotherapy drug, is adsorbed into PCN-222 via the solvent diffusion technique. Based on an analysis of the Oridonin release profile, results suggest that it can last for more than 7 days in vitro. And cumulative release rate of Ori at the 7 d was about 86.29% and 63.23% in PBS (pH 5.5 and pH 7.2, respectively) at 37°C. HepG2 cells were chosen to research the cytotoxicity of PCN-222@Ori and free Oridonin. The results demonstrated that the PCN-222@Ori nanocarrier shows higher cytotoxicity in HepG2 cells compared to Oridonin.

Hydroxycamptothecin (HCPT) loaded PLA nanoparticles were prepared by a facile dialysis method. Three main influential factors, PLA concentration, ratio of HCPT to PLA (wt/wt), dialysis bags with different molecule weight cutoff, were evaluated using an orthogonal design, gave the nanoparticles with an average diameter of approximately 226.8 nm and fine drug loading content (5.16%, w/w). The in vitro drug release studies exhibited a slow and prolonged release profile over 30 days. It is concluded that the new method to prepare HCPT-PLA nanoparticles resulted in improved formulation characteristics including small size, high drug loading capacity, and long sustained drug release.
