Effects of nitrovasodilators, endothelium-dependent vasodilators, and atrial peptides on cGMP

The interactions of the nitrovasodilators, endothelium-dependent vasodilators, and atrial peptides with cGMP synthesis have proved to be useful and important leads to the functions of cGMP and signal transduction mechanisms. Although considerable progress has been made, many important questions remain to be answered. Nevertheless, the guanylate cyclase-cGMP system clearly represents an important second-messenger system that mediates the effects of numerous agents.
