Both in-house human genetic and literature data have converged on the identification of leukotriene 4 hydrolase (LTA4H) as a key target for the treatment of cardiovascular disease. We combined fragmentbased crystallography screening with an iterative medicinal chemistry effort to optimize inhibitors of LTA4H. Ligand efficiency was followed throughout our structure-activity studies. As applied within the context of LTA4H inhibitor design, the chemistry team was able to design a potent compound 20 (DG-051) (Kd=26 nM) with high aqueous solubility (>30 mg/mL) and high oral bioavailability (>80% across species) that is currently undergoing clinical evaluation for the treatment of myocardial infarction and stroke. The structural biology-chemistry interaction described in this paper provides a sound alternative to conventional screening techniques. This is the first example of a gene-to-clinic paradigm enabled by a fragment-based drug discovery effort.
