Description
C-Type natriuretic peptide-22 (CNP-22) is an endogenous peptide with diverse biological activities.1,2,3 Its 22 amino acid sequence corresponds to residues 105-126 of its precursors prepro CNP, pro CNP, and CNP-53.2 CNP-22 is a selective agonist of natriuretic peptide receptors (NPRs) 2 and 3 (Kds = 7, 10.8, and >500,000 pM for NPR2, 3, and 1, respectively).1 It stimulates cGMP accumulation in HEK293 cells expressing rat NPR2 (ED50 = 2.2 nM) and relaxes isolated rat cerebral arterioles (EC50 = 0.52 nM).4,5 In vivo, CNP-22 (25 μg/kg) decreases kidney injury and oxidative and inflammatory responses in a rat model of hemorrhagic shock.6WARNING This product is not for human or veterinary use.
