ABSTRACT
The biopharmaceutics classification system( BCS) is a scientific framework or method for classifying drugs based on drug solubility and permeability,which can be used to provide drug bioavailability-absorption correlation analysis. Based on the characteristics of multi-component and multi-target of traditional Chinese medicine( TCM) as well as the concept,method and technology of BCS,the research group proposed biopharmaceutics classification system of Chinese materia medica( CMMBCS) and carried out research and data accumulation of classical prescriptions. Based on the previous research results,further development ideas under the CMMBCS concept and framework were further proposed in this study. In the course of research,the influence of the intermediate links of the complex interactions of the multi-component environment was omitted,and the component absorption studies on the main clinical effects of prescription ingredients were directly concerned,or the components and data were reversely extracted from the aspects of metabolism,pharmacodynamic pathways and absorption principles. Studies were conducted from two aspects( single component and compound prescription) to comprehensively evaluate the absorption properties of TCM compound. In the research path,the different ways in which Chinese medicine could exert its efficacy were fully considered,and CMMBCS classification and establishment rules were clarified mainly by focusing on the absorption pathway into the blood. Specifically,the network pharmacology and molecular docking technology were used to screen the compound index components of TCM; the absorption rules were studied by the physiologically based pharmacokinetic models and the absorption parameters of CMMBCS were calculated by reverse reasoning. Then the CMMBCS classification of TCM prescription was corrected by studying the efficacy or absorption pathway. In this paper,the theoretical framework and research methodology of CMMBCS were systematically improved based on the establishment of CMMBCS basic theory,the supplementary of drug-oriented research ideas and the application of modern mature Chinese medicine methodology.
