Cinaciguat, also known as BAY-58-2667, is a NO-independent activator for sGC with EC50 of ∼10 nM for heme-free/oxidized sGC. [1]
Heme-related dysfunction can lead to cardiovascular diseases with the oxidation of the heme of soluble guanylate cyclase (sGC) critically implicated in some of these cardiovascular diseases. sGC, the main nitric oxide receptor, stimulates second messenger cGMP production, however reactive oxygen species are known to scavenge NO and oxidize/inactivate the heme leading to sGC degradation. Cinaciguat binding causes a rotation of the α- helix away from the heme pocket, as this helix is normally held in place via the inhibitory His105–heme covalent bond. [2]
Cinaciguat activates sGC with EC 50 and Kd values in the low nanomolar range. This renders the compound the most potent NO-independent sGC activator reported to date. Furthermore, cinaciguat produces an additive, non-synergistic effect when combined with NO donors. Cinaciguat could also relaxe blood vessels with a high potency which is several orders of magnitude greater than the NO-donors sodium nitroprusside (SNP) and 3-morpho-linosydnonimin. In addition, the compound reduces coronary perfusion pressure in the rat Langendorff heart preparation and remains active in tissues made tolerant to glyceryl trinitrate. [1]
Cinaciguat could protect cardiomyocytes against ischemia/reperfusion injuries. Cinaciguat caused 63 and 41% reduction of infarct size when given before I/R and at reperfusion in rabbits, respectively. In addition, cinaciguat pretreatment caused a more robust 80% reductionin infarct size vs. 63% reduction when given at reperfusion and preserved cardiac function following I/R in mice, through cGMP-PKG-dependent generation of H2S in the heart and cardiomyocytes.[3]

Animal experiment: | After confirmation of DM, rats are randomised into four groups: vehicle-treated control, cinaciguat-treated control, vehicle-treated diabetic and cinaciguat-treated diabetic groups. Animals are treated for 8 weeks with 0.5% methylcellulose vehicle or with the sGC activator cinaciguat in suspension p.o. (10 mg/kg/day), starting immeadiately after DM confirmation. Water bottles are filled every morning with the same amount of fresh tap water and daily water intake is measured. Animal cages are handled with care and are not moved after water bottle replacement to prevent spilling of water from the bottles. Body weight of the animals are recorded every 2 days and the dose of cinaciguat is adjusted accordingly. |
