DOCKTITE is a versatile covalent docking workflow for drug discovery. It accurately predicts ligand poses and binding affinities, advancing the development of covalent drugs.
Area of Science:
- Computational chemistry
- Drug discovery
- Structural biology
Background:
- Covalent bond formation is crucial for many drugs.
- Existing covalent docking tools have limitations in versatility and scope.
Purpose of the Study:
- To present DOCKTITE, a versatile workflow for covalent docking.
- To overcome limitations of current covalent docking methodologies.
Main Methods:
- Developed DOCKTITE workflow in Molecular Operating Environment (MOE).
- Integrated automated warhead screening, nucleophilic side chain attachment, and pharmacophore-based docking.
- Implemented a novel consensus scoring approach.
Main Results:
- Achieved a mean RMSD of 1.74 Å for pose predictions across 35 complexes.
- Obtained a 71.4% prediction rate with RMSD below 2 Å.
- Demonstrated strong performance in virtual screening (AUC of 0.81) and correlation with experimental affinities (ρ = 0.806).
Conclusions:
- DOCKTITE is a highly versatile and accurate covalent docking tool.
- The workflow shows significant potential for accelerating covalent drug discovery.
- Validated methodology provides reliable predictions for drug design.

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
