Docking-based Virtual Screening
Docking-based virtual screening is a crucial component of computer-aided drug design (CADD), offering a systematic and efficient approach to identify potential drug candidates. It involves the simulation of the interaction between a ligand (potential drug molecule) and a target protein receptor to predict the binding affinity and potential efficacy. At CD ComputaBio, we provide comprehensive docking-based virtual screening services to expedite the drug discovery process.
Introduction to Docking-based Virtual Screening
The field of drug discovery has witnessed significant advancements with the integration of computational techniques. Docking-based virtual screening has emerged as a powerful tool that helps narrow down the vast chemical space and prioritize compounds for further experimental evaluation. It allows for the rapid assessment of millions of compounds, providing valuable insights into their binding modes and affinities.

Our Service
Accurate Docking Protocol Development
We customize and optimize docking protocols based on the characteristics of your target protein and ligand library to ensure reliable and reproducible results.
For instance, when dealing with a G-protein coupled receptor (GPCR), we consider specific features like the receptor's conformational flexibility and ligand binding site topology.
Post-Docking Optimization and Lead Selection
Once potential hits are identified, we apply additional filters and scoring functions to refine the selection and prioritize leads for synthesis and testing. This might involve considering factors like druglikeness, synthetic accessibility, and ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) properties.
Binding Mode Analysis and Prediction
We provide detailed analysis of the predicted binding modes of ligands, helping you understand the molecular interactions at the atomic level.
This includes hydrogen bonds, hydrophobic interactions, and electrostatic forces.
Large-scale Virtual Screening Campaigns
Our high-performance computing infrastructure enables us to handle extensive ligand databases, screening millions of compounds in a short period.
This is crucial for uncovering novel hits that might otherwise go unnoticed.
The Process of Docking-based Virtual Screening
Target Preparation
We obtain the three-dimensional structure of the target protein and perform necessary preprocessing.
01
Ligand Library Assembly
We compile a diverse and relevant ligand library based on your requirements and the nature of the target.
02
Docking Simulation
Using advanced docking software, we perform the docking of ligands to the target protein, generating multiple poses for each ligand.
03
Scoring and Ranking
The binding affinities of the ligand-protein complexes are calculated and ranked based on various scoring functions.
04
Approaches to Docking-based Virtual Screening
Rigid Docking
This approach assumes a fixed conformation of both the ligand and the protein during the docking process, providing a quick and initial assessment.
Density Functional Theory (DFT)
Allows for conformational changes in either the ligand or the protein (or both) to better capture the dynamic nature of the binding process.
Ensemble Docking
Incorporates multiple conformations of the target protein to account for its conformational heterogeneity.
