The recent gain in knowledge over the last ten years on the intracellular mechanisms which regulate vascular smooth muscle tone has expanded opportunities for the potential discovery of novel vasodilator/antihypertensive agents. This review focuses on three intracellular enzyme systems: myosin light chain kinase (MLCK) and protein kinase C (PKC), which are Ca2+-regulated protein kinases implicated in the control of smooth muscle tone, and the cGMP phosphodiesterases (PDEs), which regulate the levels of cGMP in smooth muscle (Fig. 1).
