FABP4 has been implicated as a therapeutic target for treating diabetes and atherosclerosis. Structure-based drug design (SBDD) based on initial hits from high-throughput and fragment screens yielded 216 ligand-bound structures of human FABP3, FABP4 and FABP5 isoforms, many of which were at resolutions of better than 1.2 Å. An estimated 15% of the ligands had a different chemical composition to that expected from the starting materials or the final synthesis product, highlighting a potential problem inherent to all SBDD campaigns conducted at lower resolution. Apart from possible human error during compound registration, side reactions such as additions, eliminations, isomerizations, cyclizations and dimerizations were found that led to compounds capable of binding to FABP.
