| Structure: |
|
| DrugBank Description: | Bosentan is a dual endothelin receptor antagonist marketed under the trade name Tracleer by Actelion Pharmaceuticals. Bosentan is used to treat pulmonary hypertension by blocking the action of endothelin molecules that would otherwise promote narrowing of the blood vessels and lead to high blood pressure. |
| CAS Number: | 147536-97-8 |
| Molecular Weight: | 551.614 |
| DrugBank Indication: | Used in the treatment of pulmonary arterial hypertension (PAH), to improve exercise ability and to decrease the rate of clinical worsening (in patients with WHO Class III or IV symptoms). |
| DrugBank Pharmacology: | Bosentan belongs to a class of drugs known as endothelin receptor antagonists (ERAs). Patients with PAH have elevated levels of endothelin, a potent blood vessel constrictor, in their plasma and lung tissue. Bosentan blocks the binding of endothelin to its receptors, thereby negating endothelin's deleterious effects. |
| DrugBank MoA: | Endothelin-1 (ET-1) is a neurohormone, the effects of which are mediated by binding to ET<sub>A</sub> and ET<sub>B</sub> receptors in the endothelium and vascular smooth muscle. It displays a slightly higher affinity towards ET<sub>A</sub> receptors than ET<sub>B</sub> receptors. ET-1 concentrations are elevated in plasma and lung tissue of patients with pulmonary arterial hypertension, suggesting a pathogenic role for ET-1 in this disease. Bosentan is a specific and competitive antagonist at endothelin receptor types ET<sub>A</sub> and ET<sub>B</sub>. |
| Targets: | Endothelin-1 receptor antagonist; Endothelin B receptor antagonist |
