Implication

In vitro study demonstrates novel FABP4 inhibitors attenuate inflammation in activated microglia, suggesting therapeutic potential for neurodegenerative diseases.

Key Points

To evaluate whether novel fatty acid-binding protein 4 (FABP4) inhibitors designed for improved blood–brain barrier penetration can reduce inflammatory responses in activated microglia.
Measured the binding affinity of four novel FABP4 inhibitors (MFP-0011462, MFP-0012314, MFP-0012318, and MFP-0012328) using isothermal titration calorimetry.
Tested compound solubility, cellular toxicity, reactive oxygen species (ROS) generation, and TNF-α expression and secretion in lipopolysaccharide (LPS)-activated BV-2 microglia.
All tested inhibitors were soluble in aqueous buffer up to 100 µM and exhibited binding affinities (KD) ranging from 316 nM to > 100 µM.
Reduction of LPS-induced ROS generation correlated directly with FABP4 binding affinity, with the most potent inhibitor (MFP-0012328) decreasing TNF-α gene expression by 17% and extracellular release by 25%.
