Sample solution is provided at 25 µL, 10mM.
Riociguat is an oral stimulator of soluble guanylate cyclase (sGC) used in the treatment of pulmonary hypertension.
Riocigua stimulates the recombinant sGC concentration dependently from 0.1 to 100 μM with a two-fold to 73-fold effect by an NO-independent but haem-dependent mechanism[1]. Riociguat inhibits platelet function in washed platelets but not in whole blood, and exerts no direct effects on contractility and relaxation of cardiac myocytes[2].
Riociguat (10 mg/kg/d, p.o.) partially reverses the pulmonary arterial hypertension, the right heart hypertrophy and the structural remodelling of the lung vasculature in chronic treatment of hypoxic mice and MCT-injected rats[1].

Animal experiment: | Mice[1] For chronic intervention studies four groups of mice are used: control mice exposed for 35 days to normoxic gas (n=10); mice exposed for 21 days to hypoxic gas (n=10); mice exposed for 35 days to hypoxic gas and who receives the vehicle (2% methylcellulose solution) from day 21 to day 35 (n=10); and mice exposed for 35 days to hypoxic gas and who receives BAY 63-2521 (10 mg/kg) once a day by oral application (n=10) from day 21 to day 35. For continuous measurement of Prvs and cardiac frequency by radiotelemetry, a separate group of mice is exposed for 35 days to hypoxic gas and receives BAY 63-2521 (10 mg/kg) once a day by oral application from day 21 to day 35. In order to investigate vascular reactivity in isolated mouse lungs, an additional two groups of animals are investigated: control mice (n=12) and animals exposed for 21 days to hypoxic conditions (n=12). Rats[1] Rats are randomised for chronic BAY 63-2521 treatment, 21 days after MCT injection. The experimental groups includes rats that receives BAY 63-2521 (10 mg/kg) or vehicle (2% methylcellulose solution) by oral application, once per day. Rats are examined daily and subjected to haemodynamic measurements and histological assessment at day 35. |
