Network-based TCM Pharmacology
Jing ZhaoJing ZhaoModern Research Center for Traditional Chinese Medicine
Second Military Medical UniversityShanghai, China
Jan. 14, 2010
Sino-German Workshop on Computational systems biology approaches for cancer research and biomarker discovery
• Long history
• Efficacy and safety for complex chronic diseases
• Complicated mechanisms
Characteristics of the TCM
•Holistic, complementary, synergic •Multi-component, multi-target, multi-dimensional pharmacology

TCM databases
• The TCM database • The 3D structure database of components from Chinese traditional medicinal herbs • Traditional Chinese Medicine Information Database (TCMID )
• Large scale Natural Product Library (both virtual and material)
• ~ 120 TCM herbs
• ~ 5000 compounds , ~ 500 new compounds
In our laboratory:
Techniques usually applied to isolate active components from TCM
• Thin layer chromatography (TLC)• Column chromatography (CC)• Medium Pressure Liquid Chromatography (MPLC)• High Pressure liquid chromatography (HPLC)• High-speed countercurrent chromatography(HSCCC)• Macroporous adsorptive resins (MAR)• Molecular imprinting technique (MIT)
Compounds isolated from TCM materials that are also drugs approved by the FDA.
