Fragment-based virtual screening with docking and pose scoring
Dock a compound library against a target protein with rDock and validate the poses generated against a reference fragment using SuCOS to compare the feature overlap. Poses are filtered by a user-specified SuCOS threshold.
A list of fragments should be specified which will be used to define the cavity for docking, using the 'Frankenstein ligand' technique. For more details, please see https://www.informaticsmatters.com/blog/2018/11/23/cavities-and-frankenstein-molecules.html
Compounds are split into collections and then recombined to allow the workflow to be run in a highly parallelized fashion. To specify the level of parallelization, use the 'Collection size' parameter.
Inputs
ID | Name | Description | Type |
---|---|---|---|
All fragments (SDF) | All fragments (SDF) | Fragments in SDF format |
|
Candidate compounds (SMILES) | Candidate compounds (SMILES) | List of compounds for docking in SMILES format |
|
Collection size for docking | Collection size for docking | Parameter for parallelization of docking |
|
MOL) | Fragment for SuCOS scoring (SDF/MOL) | SDF or MOL file with the single fragment for SuCOS scoring |
|
Number of poses | Number of poses | Number of docking poses to generate per input compound |
|
Receptor (PDB) | Receptor (PDB) | PDB file for the receptor protein |
|
SuCOS threshold | SuCOS threshold | Value between 0 and 1. All poses with a SuCOS score lower than this value will be filtered out. |
