Potent and selective inhibitor of NOD1; displays 36-fold selectivity for NOD1 over NOD2 (IC50 values are 0.56 and >20 μM for NOD1 and NOD2 respectively). Inhibits NOD1-induced NF-κB activation in HEK293 cells with no cytotoxicity. Shown to alter subcellular targeting of NOD1; also thought to alter the conformation of NOD1 protein in vitro. Purity 99%.
