Potent and selective bradykinin B1 receptor antagonist (ID50 values are 2.8 and > 600 nM at B1 and B2 receptors respectively). Exhibits no intrinsic agonist activity and is resistant to aminopeptidase and kininase II (ACE) cleavage. Displays hypertensive activity in vivo.

Paquinimod is a S100A9 inhibitor preventing S100A9 binding to TLR-4.

Cell-permeable calmodulin (CaM) agonist that binds to the EF-hand/Ca2+-binding site; produces CaM-dependent activation of phosphodiesterase. Also binds to cytoplasmic sites on other Ca2+ channels, including NMDA and HIV-1 gp120-activated channels, inhibiting Ca2+-mediated cytotoxicity and apoptosis (IC50 = 52 μM). Shown to protect pancreatic acinar cells from gossypol induced necrosis. Inhibits VLA-5-mediated adhesion of mast cells to fibronectin in vitro and attenuates inflammatory cell influx in guinea pig lung in vivo.
