Description: Zegocractin, also known as CM4620, is a selective Orai1 inhibitor, prevents Ca2+ entry in acinar cells. The intravenous administration of CM4620 reduces the severity of acute pancreatitis in the rat, a hitherto untested species. SOCE via STIM1/Orai complexes promotes activation and fibroinflammatory gene expression within pancreatic stellate cells. CM4620 also decreased myeloperoxidase activity and inflammatory cytokine expression in pancreas and lung tissues, fMLF peptide-induced oxidative burst in human neutrophils, and cytokine production in human peripheral blood mononuclear cells (PBMCs) and rodent PaSCs, indicating that Orai1/STIM1 channels participate in the inflammatory responses of these cell types during acute pancreatitis.
