Nelociguat (also known as BAY60-4552) is a nitric oxide sensitive soluble guanylate cyclase stimulator (sGC stimulator). In the nitric oxide (NO) signaling pathway, soluble guanylate cyclase (sGC) is a crucial enzyme. Cyclic guanosine monophosphate (cGMP), which boosts vasodilation and inhibits smooth muscle proliferation, leukocyte recruitment, platelet aggregation, and vascular remodelling through a variety of downstream mechanisms, is synthesized by sGC upon binding of NO to its prosthetic haem group.
| ln Vitro |
In the nitric oxide (NO) signaling pathway, soluble guanylate cyclase (sGC) is an essential enzyme[1]. In addition to cytochrome P450 isoenzymes 3A4 (CYP3A4), CYP2C8, and CYP2J2, riciguat is also metabolized to BAY60-4552 via CYP1A1, which is found in the liver and lungs[2].

| ln Vivo |
GSK2181236A and BAY 60-4552 offer some protection against end-organ damage brought on by hypertension. A small dose of BAY 60-4552 reduces urine output and increases survival in rats that are prone to spontaneous hypertension and stroke. In addition to lowering microalbuminuria and reducing urine output, a high dose also attenuates the rise in mean arterial pressure. The survival rates of 46 and 69% are increased by BAY 60-4552 at doses of 0.3 and 3 mg/kg/day. Urine output is dose-dependently decreased to 79±11 and 56±10 mL/day after seven weeks of treatment with BAY 60-4552 (0.3 and 3.0 mg/kg/day)[1]. Vardenafil and BAY 60-4552 have synergistic beneficial effects that may be able to save patients who are not responding well to PDE5 inhibitor treatment following radical prostatectomy[3].

| Animal Protocol |
Rats: Oral gavage of rats is performed two hours before ischemia with vehicle (0.5% HPMC, 5% DMSO, and 0.1% Tween 80; 10 mL/kg; n=14), GSK2181236A (0.1 or 1.0 mg/kg; n=11–14), or BAY 60-4552 (0.3 or 3.0 mg/kg; n=10–12). Both when ischemia first occurs and 24 hours after reperfusion, blood is drawn. For analysis, plasma is obtained[1].

| Additional Infomation |
Nelociguat is a member of the class of pyrazolopyridines that is 1H-pyrazolo[3,4-b]pyridine which is substituted by a 2-fluorobenzyl and 4,6-diamino-5-[(methoxycarbonyl)amino]pyrimidin-2-yl groups at positions 1 and 3, respectively. It is an active metabolite of riociguat and a soluble guanylate cyclase stimulator developed by Bayer for the treatment of erectile dysfunction and heart failure. It has a role as a soluble guanylate cyclase activator, an antihypertensive agent, a drug metabolite and a vasodilator agent. It is a pyrazolopyridine, a member of monofluorobenzenes, a carbamate ester and an aminopyrimidine.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.09 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.08 mg/mL (5.09 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

| 10 mM | 0.2449 mL | 1.2243 mL | 2.4486 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
