CADD课程学习(8)-- 化合物库虚拟筛选(Virtual Screening)
PyRx:基于AutoDock的虚拟筛选软件

虚拟筛选
虚拟筛选,也称计算机筛选,即在进行生物活性筛选之前,在计算机上对化合物分子进行预筛选,以降低实际筛选化合物的数目,同时提高先导化合物的发现效率
PyRx:安装好PyRx后,需要把之前安装好的autodock4.exe 和autogrid4.exe 两个文件找贝到PyRx安装目录下,才能保证PyRX在本地的顺利运行。
PyRx虚拟筛选关键步骤:
- 利用AutoDock Wizard准备受体格点文件
- 利用Open Babel准备配体小分子
- 利用Vina Wizard进行虚拟筛选
- 虚拟筛选结果分析

PyRx虚拟筛选关键步骤:
1. 利用AutoDock Wizard准备受体格点文件




2. 利用Open Babel准备配体小分子


保存结果

4.虚拟筛选结果分析
也可在以下目录找到虚拟筛选结果,pdbgt格式文件可导入Pymol
C:\Users\Administrator.mgltools\PyRx\Macromolecules\1EP_pra
练习:
从PDB数据库中下载1IEP晶体复合物,并用下载一个小分子库文件(自己构建或者ZINC下载),利用PyRX完成虚拟筛选实践,并对结果进行分析。
其他人总结
如果配体分子小而蛋白质分子很大,不确定小分子在哪里对接时,放大格子进行盲对接,配体小分子可能在蛋白质多个地方对接,就用1.MOE寻找位点;
2.聚类分析对对接的结果进行评价;
3.查找文献寻找重要氨基酸进行对接;
4.用虚拟筛选评价小分子库的对接结果
