– Vasonatrin Peptide (VNP) TFA, a chimeric compound derived from atrial natriuretic peptide (ANP) and C-type natriuretic peptide (CNP), exhibits venodilating properties reminiscent of CNP, natriuretic effects akin to ANP, as well as unique arterial vasodilating capabilities not characteristic of either parent peptide. Additionally, VNP TFA confers cardioprotection in diabetic ischemia-reperfusion injury by attenuating endoplasmic reticulum (ER) stress through the cGMP-PKG signaling cascade [1] [2] [3].
