| Description | Riociguat (BAY 632521) is a stimulator of guanylate cyclase which causes relaxation of vascular smooth muscle and is used to treat severe pulmonary arterial hypertension. |
| In vitro | BAY 63-2521 (Riociguat) concentration-dependently stimulates the recombinant soluble guanylate cyclase (sGC) from 0.1 to 100 μM, resulting in a two-fold to 73-fold increase, through an NO-independent but haem-dependent mechanism. [1] Additionally, Riociguat impairs platelet function in isolated platelets, though it does not affect platelets in whole blood, nor does it directly influence the contractility and relaxation of cardiac myocytes. [2] [3] |
| In vivo | In a long-term study, Riociguat (10 mg/kg/d, orally) was found to partially mitigate pulmonary arterial hypertension, right heart hypertrophy, and structural remodeling of lung vasculature in hypoxic mice and monocrotaline (MCT)-injected rats. [1] |
