LY83583 is an inhibitor of soluble guanylate cyclase and of cGMP production. It inhibits soluble guanylate cyclase in human platelets with an IC50 value of 2 µM.1 LY83583 also inhibits leukotriene synthesis in guinea pig lung and rat peritoneal cells with an IC50 value of 1.8 µM and is a noncompetitive inhibitor of glutathione reductase in bovine intestinal mucosa with a Ki value of 3 µM.2,3
