== Function ==
[https://www.uniprot.org/uniprot/FABP4_HUMAN FABP4_HUMAN] Lipid transport protein in adipocytes. Binds both long chain fatty acids and retinoic acid. Delivers long-chain fatty acids and retinoic acid to their cognate receptors in the nucleus (By similarity).

== Publication Abstract from PubMed ==
Fatty-acid binding protein 4 (FABP4) is a promising therapeutic target for immunometabolic diseases, while its potential for systemic inflammatory response syndrome treatment has not been explored. Here, a series of 2-(phenylamino)benzoic acids as novel and potent FABP4 inhibitors are rationally designed based on an interesting fragment that adopts multiple binding poses within FABP4. A fusion of these binding poses leads to the design of compound 3 with an approximately 460-fold improvement in binding affinity compared to the initial fragment. A subsequent structure-aided optimization upon 3 results in a promising lead (17) with the highest binding affinity among all the inhibitors, exerting a significant anti-inflammatory effect in cells and effectively attenuating a systemic inflammatory damage in mice. Our work therefore presents a good example of lead compound discovery derived from the multiple binding poses of a fragment and provides a candidate for development of drugs against inflammation-related diseases.
