Soluble guanylate cyclase modulators in heart failure.
This review summarizes the role of soluble guanylate cyclase (sGC)-cyclic guanosine 3', 5'-monophosphate pathways in heart failure and several new drugs that modify guanylate cyclase. The sGC activators and stimulators as modulators of sGC are promising drugs in the therapy for decompensated heart failure and pulmonary hypertension. Cinaciguat is a nitric oxide (NO)-independent direct activator...
متن کاملBiochemistry of soluble guanylate cyclase.
Nitric oxide (NO) functions in biology as both a critical cytotoxic agent and an essential signaling molecule. The toxicity of the diatomic gas has long been accepted; however, it was not known to be a signaling molecule until it was identified as the endothelium-derived relaxing factor (EDRF). Since this discovery, the physiological signaling pathways that are regulated by NO have been the foc...
متن کاملCarbon Monoxide Abrogates Ischemic Insult to Neuronal Cells via the Soluble Guanylate Cyclase-cGMP Pathway
PURPOSE Carbon monoxide (CO) is an accepted cytoprotective molecule. The extent and mechanisms of protection in neuronal systems have not been well studied. We hypothesized that delivery of CO via a novel releasing molecule (CORM) would impart neuroprotection in vivo against ischemia-reperfusion injury (IRI)-induced apoptosis of retinal ganglion cells (RGC) and in vitro of neuronal SH-SY5Y-cell...
متن کاملStructural studies of soluble guanylate cyclase
Soluble guanylate cyclase (sGC) is the primary receptor for nitric oxide (NO), which enhances GTP to cGMP conversion by sGC ~200-fold. The second messenger, cGMP, further modulates the activity of kinases and ion channels and ultimately induces smooth muscle relaxation and vasodilation. In cases of endothelial dysfunction, diminished NO production and insufficient output of the NOsGC-cGMP pathw...
متن کاملRegulation of Soluble Guanylate Cyclase Activity
Alterations of the chemical structure of protoporphyrin IX markedly altered the activation of soluble guanylate cyclase purified from bovine lung. Hydrophobic side chains at positions 2 and 4 and vicinal propionic acid residues at positions 6 and 7 of the porphyrin ring (protoporphyrin IX, mesoporphyrin IX) were essential for maximal enzyme activation (K. = 7-8 nM; V, = 6-8 Kmol of cGMP/min/mg)...
