摘要
目的:用现代化学信息学手段和中草药化学数据库寻找中草药中法尼酯受体(FXR)的抑制剂。方法:采用Accelrys公司Cerius2分子模拟软件包(版本4.10)对蛋白质晶体结构数据库PDB中FXR-fexaramine复合物(PDB代码:1OSH)三维结构活性部位进行分析,通过配体对接模块进行分子对接。结果:以原配体fexaramine的打分函数为阈值,筛选出中草药化学数据库中10个与FXR结合较好的的化学成分。结论:本研究结果可促进新型降脂药物的研制,并有助于揭示药物分子与FXR的作用机制。
OBJECTIVE: To seek for the farnesoid X receptor (FXR) inhibitors from the TCM database using chemoinformatics. METHODS: Three-dimensional structure active fraction of FXR-fexaramine compound (PDB code: tOSH) was analyzed using Cerius2 4.10 software package developed by Accerlrys company. Ligandfit module was applied for molecular docking. RE- SULTS : 10 compounds which were predicted to have good interactions with FXR were screened using docking score of original inhibitor (fexaramine) and the receptor as threshold value.CONCLUSION: The study could be helpful for development of new lipid-lowering drug and further study of mechanism of FXR and pharmaceutical molecular.
