Many different herbal medicines have been evaluated for the management of various diseases such as obesity, NAFLD and T2DM. However, most potent herbal drug candidates are highly hydrophobic compound with poor water solubility, limited intestinal absorption and low oral bioavailability. Few herbal compounds are used in clinical treatments. The aim of the present project is to improve the biocompatibility and organ-targeting release of nanoparticles for clinical applications. Several nanoparticle delivery systems have been developed and evaluated for controlled release of water-insoluble and chemically unstable drugs in pharmaceutical research. In general, nanoparticles could largely enhance drug loading, promote the passage through the epithelial barrier, facilitate intracellular diffusion, allow tissue-targeting delivery, improve pharmacokinetics and reduce gastrointestinal toxicity. Compared with the liposome drug carrier systems, protein-based nanoparticles are more biocompatible and biodegradable. Human serum albumin (HAS)/bovine serum albumin (BSA) is the most abundant plasma protein with a molecular weight of 66.5 kDa and holds numerous advantages including good water-solubility, biodegradability, excellent biocompatibility, absence of toxicity, without immunogenicity, and ready availability. Thus, serum albumin is widely used to form protein-based nanoparticles with a narrow range of particle size (50-300 nm) under versatile conditions while no toxic reagents are involved. Several drug-loaded albumin nanoparticles (e.g., Abraxane) have been recently prepared and approved in clinical trials or clinical applications. Therefore, the present project will develop albumin-based nanoparticles as the most important macromolecular carriers for the preparation of new nanomedicines.
Dr JH Rong, School of Chinese Medicine
Dr Jianhui Rong is currently an Associate Professor in molecular pharmacology on Chinese medicine at School of Chinese Medicine, University of Hong Kong. Dr Rong received his PhD in Medical Biochemistry from Uppsala University, Sweden, conducted postdoctoral research at University of Alberta, Canada and visiting scholar research at School of Medicine, Yale University, USA. Since 2005, he has served as Research Assistant Professor, Assistant Professor and Associate Professor at Li Ka Shing Faculty of Medicine and School of Chinese Medicine, University of Hong Kong. Dr Rong’s research focus on the research and development of drug candidates from Chinese medicines and the discovery of basic molecular mechanisms for the treatment of neurological diseases, myocardial infarction and obesity. Dr RONG mainly use modern transcriptomics, proteomics, cell signalling technology and biotin-labelling of small molecule probes to study the protein targets and biological activity of Chinese medicines. For example, Dr RONG has discovered specific Chinese medicine compounds for regulating heme oxygenase-1 (HO-1), leukotriene B4 12-hydroxy dehydrogenase (LTB4DH), arginase 2 (Arg2), and pyruvate kinase M2 (PKM2) and endoplasmic reticulum stress protein GRP78. He has chaired over or participated in more than 30 research grants from Hong Kong Research Grants Council, Hong Kong Health and Medical Research Fund, Hong Kong Science and Technology Innovation Fund, National Natural Science Foundation of China and the Seed Research Fund of the University of Hong Kong; obtained several international patents, US patents, Chinese patents; and published more than 70 SCI papers in internationally renowned journals such as Chemical Science, Journal of Controlled Release, Molecular Neurobiology, ACS Chemical Neuroscience, Journal of Nutritional Biochemistry, Molecular Immunology, Neuropharmacology and Biochemical Journal. Dr Rong also serves as the executive member or committee member for several academic organisations, and reviewer for several international academic journals.
