                                                    LY83583 is a cell-permeable and competitive inhibitor of soluble guanylate cyclase (sGC) with an IC50 value of 2 µM.

                                                    In vitro screening using a recombinant catalytic domain of CaMps1p identified LY83583 (6-anilino-5,8-quinolinedione), known as a guanylate cyclase inhibitor, to be blocking CaMps1p kinase activity. In addition to its in vitro kinase inhibition, LY83583 reduced the growth rate of C. albicans. LY83583 showed specific inhibition for CaMps1p with no effect on hMps1p activity.

                                                    These relationships were studied by monitoring the effects of muscarinic agonists on tension and cyclic GMP levels in rabbit left atrial strips and aortic rings, in the presence and absence of the cyclic GMP lowering agent, LY83583. LY83583 completely blocked both the cyclic GMP increase and the relaxation caused by acetylcholine in rabbit aortic rings with intact endothelial cells.
