CFM 1571 hydrochloride is a chemical compound that acts as a stimulator of the nitric oxide receptor known as soluble guanylate cyclase (sGC). It demonstrates an EC50 value of 5.49 μM and an IC50 value of 2.84 μM. Soluble guanylate cyclase is an important signal-transduction enzyme that is activated by nitric oxide. The compound CFM 1571 hydrochloride shows potential for use in cardiovascular and other disease research [1] [2].
Nicorandil-d4 is intended for use as an internal standard for the quantification of nicorandil by GC- or LC-MS. Nicorandil is an activator of sulfonylurea receptor 2B (SUR2B) linked to ATP-sensitive potassium channel Kir6.2 (EC50 = ~10 µM) and a nitric oxide (NO) donor. It is selective for SUR2B/Kir6.2 over the SUR2A/Kir6.2 channel (EC50 = >500 µM). Nicorandil activates soluble guanylate cyclase in a cell-free assay and relaxes partially depolarized isolated bovine coronary artery strips (EC50 = 4.4 µM). It decreases mean blood pressure, coronary resistance, and heart rate, as well as increases coronary sinus outflow, in dogs when administered intravenously at a dose of 1 mg/kg. Nicorandil increases survival and decreases infarct size in a rabbit model of myocardial ischemia-reperfusion injury induced by left coronary artery occlusion. Formulations containing nicorandil have been used in the treatment of angina pectoris.
