Abstract/OtherAbstract:
The natriuretic peptides, specifically atrial natriuretic peptide (ANP), are increasingly recognized to play a fundamental role in blood pressure (BP) regulation. This role in BP regulation reflects the pluripotent cardiorenal actions of ANP, which include diuresis, enhancement of renal blood flow and glomerular filtration rate, systemic vasodilatation, suppression of aldosterone, and inhibition of the sympathetic nervous system. These actions of ANP, in addition to recent human studies demonstrating an association of higher plasma ANP with lower risk of hypertension, support the development of an ANP-based therapy for hypertension. M-ANP is a novel ANP-based peptide that is resistant to proteolytic degradation and possesses greater BP-lowering, renal function-enhancing, and aldosterone-suppressing properties than native ANP. In an animal model of hypertension, M-ANP lowers BP via multiple mechanisms, including vasodilatation, diuresis, and inhibition of aldosterone. Importantly, M-ANP enhances both glomerular filtration rate and renal blood flow despite reductions in BP. The pluripotent BP-lowering actions and concomitant enhancement of renal function associated with M-ANP are highly attractive characteristics for an antihypertensive agent and underscore the therapeutic potential of M-ANP. M-ANP currently is heading into clinical testing, which may advance this novel strategy for human hypertension.
