the costructure of small-molecule ligands and their
respective target proteins has been a long-standing problem in drug
discovery. For weak binding compounds typically identified in fragment-based
screening (FBS) campaigns, determination of the correct binding site
and correct binding mode is usually done experimentally via X-ray
crystallography. For many targets of pharmaceutical interest, however,
establishing an X-ray system which allows for sufficient throughput
to support a drug discovery project is not possible. In this case,
exploration of fragment hits becomes a very laborious and consequently
slow process with the generation of protein/ligand cocrystal structures
as the bottleneck of the entire process. In this work, we introduce
a computational method which is able to reliably predict binding sites
and binding modes of fragment-like small molecules using solely the
structure of the apoprotein and the ligand’s chemical structure
as input information. The method is based on molecular dynamics simulations
and Markov-state models and can be run as a fully automated protocol
requiring minimal human intervention. We describe the application
of the method to a representative subset of different target classes
and fragments from historical FBS efforts at Boehringer Ingelheim
and discuss its potential integration into the overall fragment-based
drug discovery workflow.
