Abstract
The natriuretic peptide (NP) family consists of structurally similar, although physiologically distinct, peptides that play an important role in cardiorenal homeostasis. CD-NP is a novel chimeric natriuretic peptide developed by the Mayo Clinic, in which the 15-amino acid COOH-terminus of dendroaspis NP is fused to C-type NP. CD-NP is a dual activator of NP receptors A and B, and therefore, possesses the strong antiproliferative and antifibrotic properties of C-type NP with the potent natriuretic, diuretic, and aldosterone-inhibiting properties of dendroaspis NP. CD-NP has favorable cardiorenal properties when compared to recombinant B-type NP (nesiritide), including preservation of glomerular filtration rate with minimal blood pressure-lowering effects. Thus, CD-NP has emerged as an appealing novel therapeutic strategy for heart failure. The endogenous NP system, the development rationale for CD-NP, as well as in vitro, animal, and human studies and future directions will be reviewed.
