Pulmonary arterial hypertension is a chronic and life-threatening disease that if left untreated is fatal. 2008;48:926–34. Guanylate cyclase (guanylyl cyclase, GC), which catalyzes the formation of cGMP from GTP, exists in both the soluble and particulate fractions of cells. The sample cGMP concentration was determined (as pmol/mg tissue) using the equation obtained from the standard curve. To date, pharmacological interventions have had limited success in improving the health status of patients with HFpEF. Soluble guanylate cyclase (sGC) stimulation reduces inflammation and fibrosis in experimental models of lung, kidney and heart disease. There are membrane-bound (type 1, guanylate cyclase-coupled receptor) and soluble (type 2, soluble guanylate cyclase) forms of guanylate cyclases. kg −1.

Data published in literature revealed no additional benefits to guideline-based medical therapy in reducing incidence of heart failure hospitalization and mortality with sGC stimulator use. Soluble guanylate cyclase (sGC) is the human receptor of nitric oxide (NO) in numerous kinds of cells and produces the second messenger 3′,5′-cyclic guanosine monophosphate (cGMP) upon NO binding to its heme. The Soluble Guanylate Cyclase Stimulator in Heart Failure with Reduced Ejection Fraction Study (SOCRATES-REDUCED) was designed to evaluate the effect on natriuretic peptide trajectory and tolerability of 12 weeks of treatment with 4 doses of oral vericiguat (BAY1021189), a novel once-daily sGC stimulator, in clinically stable patients with worsening chronic HF and reduced LVEF.

Praliciguat (IW-1973) is a soluble guanylate cyclase (sGC) stimulator under development for the treatment of diabetic nephropathy (DN; ClinicalTrials.gov Identifier NCT03217591) and heart failure with preserved ejection fraction (HFpEF; ClinicalTrials.gov Identifier NCT03254485). Soluble Guanylate Cyclase (sGC) is the intracellular receptor of Nitric Oxide (NO). Some studies implicate this pathway as having a role in attention deficiency and hyperactive behavior. Soluble guanylate cyclase (sGC), a key enzyme in the NO-cGMP signaling pathway, catalyzes the formation of cGMP in response to NO binding. Each sample was determined in triplicate and the process repeated twice. Riociguat is an oral stimulator of the NO receptor soluble guanylate cyclase. Soluble guanylate cyclase (sGC), a key signal-transduction enzyme, increases the conversion of guanosine-5′-triphosphate to cGMP upon binding of nitric oxide (NO). Now, 20 years later, the stimulator of soluble guanylate cyclase (sGC), riociguat, is on the market and is the only drug approved for the treatment of two forms of pulmonary hypertension (PAH/CTEPH), and a variety of other sGC stimulators and sGC activators are in preclinical and clinical development for additional indications. This treatment stimulates soluble guanylate cyclase, increasing cyclic guanosine monopho-sphate (cGMP) levels and activating protein kinase G (PKG) in the cytosol, resulting in subsequent relaxation A cell-permeable pyrazolopyridinylpyrimidine compound that acts as a selective and potent stimulator of soluble guanylate cyclase (effective dose ~ 0.1 nM to 100 µM using recombinant soluble guanylate cyclase). Core Tip: Recently soluble guanylate cyclase (sGC) stimulators (vericiguat and riociguat) have emerged as a novel treatment for heart failure with reduced or preserved ejection fraction. Frey R, Mück W, Unger S, et al. Guanylate cyclase is a lyase enzyme that converts guanosine triphosphate to cyclic guanosine monophosphate and pyrophosphate. It is often part of the G protein signaling cascade that is activated by low intracellular calcium levels and inhibited by high intracellular calcium levels.

A soluble guanylate cyclase (sGC) stimulator is known as a drug for treatment of pulmonary arterial hyperten-sion in SSc patients. reported in 1994 that the new compound YC-1 acted as a direct, that is, NO- independent, stimulator of sGC (Ko et al. *: p<0.05 versus control; # : p<0.05 versus hypoxia at day 35. Health status was assessed with the disease‐specific Kansas City Cardiomyopathy Questionnaire (KCCQ) and the generic health‐related quality of life measure EQ‐5D. In total, 477 patients were randomized 12.9 ± 9.0 days after hospitalization or if requiring outpatient treatment with intravenous diuretics for HF. The activation of sGC results in the conversion of Guanosine Triphosphate (GTP) to the secondary messenger cyclic Guanosine Monophosphate (cGMP). Adult male Sprague-Dawley rats (350 to 400 g body wt) and C57Bl/6J and NOS3−/− (Nos3tm1Unc, Jackson Laboratories) mice were obtained from Charles River Laboratories. 7, 8 Soluble guanylate cyclase (sGC)‐derived generation of cyclic guanosine monophosphate (cGMP) is impaired in HFpEF 9 and may represent a novel treatment target.
