The CNS-penetrant soluble guanylate cyclase stimulator CYR119 attenuates markers of inflammation in the central nervous system.

Background: Inflammation in the central nervous system (CNS) is observed in many neurological disorders. Nitric oxide-soluble guanylate cyclase-cyclic guanosine monophosphate (NO-sGC-cGMP) signaling plays an essential role in modulating neuroinflammation. CYR119 is a CNS-penetrant sGC stimulator that amplifies endogenous NO-sGC-cGMP signaling.

The CNS-Penetrant Soluble Guanylate Cyclase Stimulator CY6463 Reveals its Therapeutic Potential in Neurodegenerative Diseases.

Effective treatments for neurodegenerative diseases remain elusive and are critically needed since the burden of these diseases increases across an aging global population. Nitric oxide (NO) is a gasotransmitter that binds to soluble guanylate cyclase (sGC) to produce cyclic guanosine monophosphate (cGMP). Impairment of this pathway has been demonstrated in neurodegenerative diseases.

Discovery of CYR715: A novel carboxylic acid-containing soluble guanylate cyclase stimulator.

Soluble guanylate cyclase (sGC) is a clinically validated therapeutic target in the treatment of pulmonary hypertension. Modulators of sGC have the potential to treat diseases that are affected by dysregulation of the NO-sGC-cGMP signal transduction pathway. This letter describes the SAR efforts that led to the discovery of CYR715, a novel carboxylic acid-containing sGC stimulator, with an improved metabolic profile relative to our previously described stimulator, IWP-051.

Olinciguat, an Oral sGC Stimulator, Exhibits Diverse Pharmacology Across Preclinical Models of Cardiovascular, Metabolic, Renal, and Inflammatory Disease.

Nitric oxide (NO)-soluble guanylate cyclase (sGC)-cyclic 3',5' GMP (cGMP) signaling plays a central role in regulation of diverse processes including smooth muscle relaxation, inflammation, and fibrosis. sGC is activated by the short-lived physiologic mediator NO. sGC stimulators are small-molecule compounds that directly bind to sGC to enhance NO-mediated cGMP signaling.

Pharmacokinetics, mass balance, tissue distribution, metabolism, and excretion of praliciguat, a clinical-stage soluble guanylate cyclase stimulator in rats.

The pharmacokinetics (PK), metabolism, excretion, mass balance, and tissue distribution of [ C]praliciguat were evaluated following oral administration of a 3-mg/kg dose in Sprague-Dawley rats and in a quantitative whole-body autoradiography (QWBA) study conducted in male Long-Evans rats. Plasma T was 1 hour and the t of total plasma radioactivity was 23.7 hours.

Discovery of IWP-051, a Novel Orally Bioavailable sGC Stimulator with Once-Daily Dosing Potential in Humans.

In recent years, soluble guanylate cyclase (sGC, EC 4.6.1.

The relationship between pregnancy and oxidative stress markers on patients undergoing ovarian stimulations.

Purpose: We investigated the activities and relevance of a validated panel of antioxidant enzymes, cytokines, specific lipid peroxidation end products and six fatty acids by correlational analyses with peak E(2) levels and pregnancy outcome after ovarian stimulation for IVF or IUI.

Methods: Blood samples obtained from 15 patients undergoing ovarian stimulation with rFSH or hMG were divided into two groups. Group-1 was baseline blood collected on day-2-3 of women cycle.
