Abstract:
:We herein describe the synthesis and anti-inflammatory properties of a small library of imidazoline-based NF-kappaB inhibitors. The structure-activity relationship of various substituents on an imidazoline core structure was evaluated for the ability to inhibit NF-kappaB mediated IL-6 production. Optimization of the scaffolds was pursued by correlating luciferase-based NF-kappaB reporter assays with inhibition of IL-6 production in IL-1beta stimulated human blood. Several derivatives were found to inhibit NF-kappaB mediated IL-6 production in the nanomolar range in IL-1beta stimulated human blood.
