Discovery of highly selective inhibitors of human fatty acid binding protein 4 (FABP4) by virtual screening

In this study, a series of small molecule inhibitors of human FABP4 were identified through virtual screening. Compound 1 is the most potent hit against FABP4 with a selectivity of more than 144-fold preferences over human FABP3. In addition, MD simulation and mutation studies revealed key residues for inhibitory potency and selectivity, which provides a guideline for further drug design against obesity, diabetes and atherosclerosis.
