The renal outer medullary potassium (ROMK) channel is a member of the inwardly rectifying family of potassium (Kir, Kir1.1) channels. It is primarily expressed in two regions of the kidney, the cortical collecting duct (CCD) and the thick ascending loop of Henle (TALH). At the CCD it tightly regulates potassium secretion while controlling potassium recycling in TALH. As loss-of-function mutations lead to salt wasting and low blood pressure, it has been surmised that inhibitors of ROMK would represent a target for new and improved diuretics for the treatment of hypertension and heart failure. In this review, we discuss and provide an overview of the medicinal chemistry approaches toward the development of small molecule ROMK inhibitors over the past decade.
