  • PubMed Abstract: 

    Low micromolar human A-FABP inhibitors were found by utilizing a fluorescence polarization assay, X-ray crystallography and modeling. The carbazole- and indole-based inhibitors displayed approximately 10-fold preferences over human H-FABP and E-FABP, and are highly selective against I-FABP. This communication describes the SAR for drug-like synthetic inhibitors of human A-FABP.
