Short Biography:

Dr. Jianhui RONG received his PhD degree in medical biochemistry from Uppsala University (Sweden) in 2000. Prior to joining Li Ka Shing Faculty of Medicine, The University of Hong Kong, Dr RONG was a Post-doctoral Fellow at University of Alberta (Canada). From 2005 to 2006, Dr RONG was a visiting scholar at Yale University Medical School (USA). Dr RONG is currently Associate Professor at School of Chinese Medicine, The University of Hong Kong.

Dr. RONG is mainly interested in the active ingredients and analogues from traditional Chinese medicine and the underlying molecular mechanisms for treating neurological diseases, myocardial infarction and obesity. In the past a few years, Dr RONG’s group have discovered the active compounds and molecular mechanisms for the regulation of HO-1, LTB4DH, Arginase-2, PKM2, and GRP78 against oxidative stress, inflammation and fibrosis in neurodegeneration, myocardial infarction and obesity.

Dr. RONG has chaired or participated in more than 20 research grants from the Hong Kong Research Grants Council, the Hong Kong Healthcare Research Fund, the National Natural Science Foundation and the Hong Kong University Seed Research Fund. Dr RONG has published dozens of SCI papers in internationally renowned journals and obtained several international patents. Meanwhile, Dr RONG has long served as reviewer for various international academic journals.

Biography

Dr Jianhui Rong’s research interests focus on the molecular characterization of anti-inflammatory, cardioprotective and neurotrophic activities of Chinese medicines against obesity, myocardial injury and neuroinflammation. Our strategy involves three major steps: 1) to profile the biological response fingerprints (BioReF) and proteomic response fingerprints (ProReF) of complex herbal medicine formulations for the discovery of the potential protein targets; 2) to identify the bioactive compounds for specific protein targets through a bioactivity-guided fractionation procedure; 3) to discover the covalent and non-covalent drug-protein interactions for drug discovery through chemical biology approaches. Our earlier effort was to use the selected signature genes for mechanistic studies and new quality control metrics. With the support of several previous GRF grants, we have successfully identified the active compounds for several representative gene products including heme oxygenase-1 (HO-1) and NADP-dependent leukotriene B4 12-hydroxydehydrogenase (LTB4DH) through bioactivity-guided fractionation procedure. We recently focused on the identification of covalent drug-protein conjugates for several active compounds including N-propargyl caffeamide, arachidonic acid metabolites and pentacyclic triterpene celastrol. We further employed molecular simulation and chemical biology techniques to develop specific drug candidates. We have established different cell models and animal models for pharmacological evaluation of the bioactive compounds.

Our recent research focus is well described by the following papers: 1) N-Propargyl caffeate amide (PACA) potentiates nerve growth factor (NGF)-induced neurite outgrowth and attenuates 6-hydroxydopamine (6-OHDA)-induced toxicity via activating the Nrf2/HO-1 pathway (ACS Chemical Neuroscience, 2015). This paper described the synthesis of small molecule probe PACA the discovery of covalent PACA-Keap1 conjugate; 2) Plant natural product puerarin ameliorates depressive behaviors and chronic pain in mice with spared nerve injury (SNI) (Molecular Neurobiology, 2017). This paper described the discovery of Chinese medicine puerarin as dual antidepressant and analgesic drug candidate; 3) ω-Alkynyl arachidonic acid promotes anti-inflammatory macrophage M2 polarization against acute myocardial infarction via regulating the cross-talk between PKM2, HIF-1α and iNOS (Biochim Biophys Acta- Molecular and Cell Biology of Lipids, 2017); 4) N-Propargyl caffeamide skews macrophages towards an M2-like phenotype against myocardial ischemic injury via activating Nrf2/HO-1 pathway and inhibiting NF-κB pathway (Cellular Physiology & Biochemistry, 2018). This paper called attention to the adverse interactions between the botanicals and endogenous neurotransmitters while effort is made to elucidate the pharmacological potential of various active compounds in herbal medicines.

Collectively, we have developed an integrative technology platform for better understanding on the basic mechanisms underlying the therapeutic potential of complex herbal medicines. We strived to dissect the interactions between the active compounds in complex herbal medicines and the protein targets for the development of new mechanism-specific medicines.
