sGC[1]
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].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2 mg/mL (4.73 mM); Clear solution
This protocol yields a clear solution of ≥ 2 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: 2 mg/mL (4.73 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
Protokoll
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.
