Overview

Molecular docking is an approach to drug design by characterizing the receptor and the mode of interaction between the receptor and the drug molecule. It is a theoretical modeling method that focuses on the study of intermolecular (e.g., ligand-receptor) interactions and the prediction of their binding modes and affinities. At CD ComputaBio, we offer a full suite of molecular docking services tailored to meet the diverse needs of our clients. Our expertise allows us to assist in the virtual screening, lead optimization, and drug design process, ultimately accelerating the drug discovery process.

Our Services Process

Prepare the ligand structure files and pre-processing them (structure conversion and structure optimization).
Prepare the protein crystal structure file, and preprocess it (structure repair and adjustment).
if there is no protein crystal structure, we need the complete amino acid sequence for structure modeling.
After preparing the protein, we must perform active site prediction to determine the approximate docking pocket position.
Using the center of the predicted pocket position as the coordinate origin to establish the docking box, the shape and size depend on the project.
Docking box size and other parameters are set according to the docked ligand information (e.g. ligand size).
After the above steps are determined, the final docking parameters need to be set as well as the docking accuracy selected.
Check the structure and parameter files, call the server resources to start, and start the docking program according to the project.

Applications

CD ComputaBio's molecular docking services are used in a wide range of drug discovery and development areas, including:

Figure 2. Applications of Molecular Docking.

Therapeutic Drug Design: Identify and optimize small molecule drug candidates for a wide range of diseases, from cancer to infectious diseases and neurodegenerative disorders.
Fragment Drug Design: Facilitate the rational assembly of hit fragments into high-affinity lead compounds through protein-ligand interaction analysis.
Protein-Protein Interaction Modulation: Study the binding interface of protein-protein complexes to guide the design of interferents or stabilizers for specific interactions.

Sample Requirements

Receptor information	PDB database protein number is required Uniprot database protein/gene number is required Protein species information and complete amino acid sequence Protein active site information Relevant references
Ligand information	If the ligand is a protein co-receptor information requirements Provide CAS number or SMILES for ordinary small molecules Ordinary small molecules can also provide the structure directly (Chemdraw software is recommended) Ordinary small molecules try to provide 2D structure files (sdf/mol2 and other common formats)
Active site information	The receptor protein provided does not have active site information and requires additional AI site prediction service.

Analysis of Results

Upon completion of a molecular docking study, clients can expect a comprehensive and in-depth analysis of the results obtained, including

Binding Pattern Visualization: Detailed visual representation of ligand-protein interactions, highlighting key residues involved in binding as well as potential hydrogen bonding and hydrophobic interactions.
Binding Affinity Ranking: Comprehensive ranking of ligands based on their predicted binding energies to help identify high-affinity lead compounds.
Interaction Fingerprints: Quantitative summaries of intermolecular interactions that provide valuable insights into specific binding modes and hotspots within the binding site.
