[Abstract]:Objective: professor Deng Tietao, a master of Chinese medicine, has been using Jiawei Buzhong Yiqi decoction in the treatment of myasthenia gravis (MG) for decades, and its therapeutic effect is very remarkable. In this study, taking Jiawei Buzhong Yiqi decoction as an example, the therapeutic effect of Jiawei Buzhong Yiqi decoction on MG was studied by using data mining, determining target, establishing database and virtual screening. Among the envoys, the herbs targeting acetylcholinesterase (AChE) were found, the main skeleton structures of AChE compounds were found for the main anti-AChE herbs, and the new AChE inhibitors were found. Inspired by traditional Chinese medicine compound, a new method of finding active compounds quickly. Methods: 1. To study the pathogenesis of MG and determine AChE as the research target, the crystal protein structure of AChE was obtained from the protein database. 2. The chemical composition database and known AChE inhibitor database of traditional Chinese medicine compound Junchen Zoran were established by data mining. 3. In this study, the Lipinski five rules were used to screen the properties of the compounds. 4. Two dimensional (2D), three dimensional (3D) similarity superposition technique and Glide molecular docking technique were used to screen the chemical components of traditional Chinese medicine based on AChE inhibitor ligands. 5. Skeleton analysis, a new skeleton of potential anti-AChE active compounds was obtained, and the same skeleton compounds were purchased from commercial databases. 6. The IC50 values of 24 compounds were determined by donepezil as positive reference, and 5 active compounds were found by Ellman enzyme analysis. 7 the results were verified by molecular dynamics simulation. The reliability of predicting active compounds based on virtual screening of molecular docking was verified. Results: through the study of the pathogenesis of MG, the main research targets of AChE were predicted. It was found that the anti-AChE active components in Jiawei Buzhong Yiqi decoction were mainly flavonoids. At the same time, a new kind of anti-AChE compound skeleton was also found. Five new AChE inhibitors X4, X10, X11 were found by experiments. The IC _ (50) of X19 and X21 are 6.5 鹵0.23 渭 M, 11.4 鹵2.72 渭 M, 7.1 鹵1.34 渭 M, 10.9 鹵0.48 渭 M and 2.3 鹵0.15 渭 M, respectively. Molecular dynamics simulation shows that the predicted binding free energy G value is consistent with the data of the biological activity of the new AChE inhibitor, and there is a linear relationship between the predicted binding free energy G value and the biological activity of the new binding free energy G. It shows the reliability of the technology of screening active compounds through molecular docking. This study shows that the discovery of new active compounds can be inspired by the skeleton of active components of Chinese medicinal materials. Conclusion: the conclusions of this study are as follows: (1) Jiawei Buzhong Yiqi decoction has therapeutic effect on myasthenia gravis, in which monarch medicine and make medicine play a major role. Subjects and adjuvants may have different functions in the treatment of myasthenia gravis. (2) the main active components are flavonoids derivative AChE inhibitors. (3) five new skeleton AChE inhibitors have been found in this paper. (4) in this paper, five new skeleton AChE inhibitors have been found. (4) the main active components are flavonoids derivative AChE inhibitors. To provide new research methods, From the traditional classical prescription of traditional Chinese medicine, combined with data mining method, the active components of traditional Chinese medicine compound were studied, and the active compounds were found.
