Dr Ouyang has pioneered the application of molecular modeling techniques in the field of drug delivery - 'computational pharmaceutics' - to explore the mechanism of drug delivery at the molecular level and then develop novel drug delivery systems. Computational pharmaceutics has great potential to shorten the time-consuming process of formulation development and decrease high cost of formulation development by reducing trial-and-error in the conventional experiments.
Cyclodextrin formulation. Cyclodextrins are a family of cyclic oligosaccharides, which are widely used for the solubilization of poor-soluble drugs. Molecular modeling techniques are able to screen the optimal formulation.
Solid dispersion formulation. Solid dispersion refers to the dispersion of one or more drug molecules (usually poorly-soluble drugs) in the carriers at the solid state by different preparation methods (e.g. hot melt-extrusion method). Molecular modeling techniques are used to predict the long-term physical stability, and then screen the optimal formulation.
- Non-viral gene delivery systems. The key to gene therapy is the development of safe,efficient and biocompatible non-viral vectors for gene delivery. Our novel simulation approaches are able to extend our understanding of key mechanistic aspects of gene-carrier complexation, thereby advancing the rational design of non-viral gene delivery systems.
