Systematic research of secondary development of Shufeng Jiedu Capsule / 中草药

ABSTRACT

The study of secondary development of major Chinese materia medica varieties is the important content of Chinese materia medica (CMM) innovation research, and it is also the important approach of inheriting and developing traditional Chinese medine (TCM) theory and breaking the bottleneck restricting of the development of TCM theory and CMM industry. In this paper, the secondary development of Shufeng Jiedu Capsule (SJC) was systematically studied. The chemical components of SJC were elucidated by the identification and characterization of herbs, SJC and components ingested into the blood. The main effective components were further screened and cleared by integrating UPLC-Q/TOF-MS, NF-κB double luciferase reporter gene system, binding experiments of G protein coupled receptors, network pharmacology analysis, and spectrum-efficiency screening method. Based on the traditional efficacy, the mechanism of SJC was explained in terms of anti-inflammatory immunity, antipyretic effect, pharmacokinetics and tissue distribution of the main components based on the methods of animal model and genomics. The formula features, compatibility regularity were clarified and the action properties, comparative advantages and core clinical value were found and refined by the research of decomposed recipes and the comparison with the similar CMM recipes and chemical drugs. The quality control systems of SJC and related herbs were established by content determination of multi-target ingredients and multi-batch samples, and the establishment of the characteristic mode of HPLC fingerprint. The original quality standards were promoted comprehensively to ensure the uniformity, stability and controllability of product quality. This study not only provided important theoretical and experimental basis for clinical application and guidance of clinical practice, but also provided research ideas and modes for the secondary development of other major CMM varieties.
