Bosentan hydrate Chemische Eigenschaften,Einsatz,Produktion Methoden

Verwenden
Antagonist (endothelin receptor).
Verwenden
Bosentan hydrate has been used in cell viability assay. It has also been used as a positive control for calcium transient analysis.
Definition
ChEBI: Bosentan hydrate is a hydrate. It contains a bosentan.
Trademarks
Tracleer (Actelion).
Biologische Aktivität
a sulfonamide-derived, competitive and specific endothelin receptor antagonist with a relatively higher affinity to the endothelin a receptor than endothelin b receptor. by competitively binding to endothelin a and endothelin b receptors in the endothelium and vascular smooth muscle, bosentan offset the effect of endothelin which is an extremely potent endogenous vasoconstrictor and broncho-constrictor. in addition, bosentan decreases both pulmonary and systemic vascular resistance and is particularly applied in the treatment of pulmonary arterial hypertension. [1]
Biochem/physiol Actions
Bosentan is an endothelin receptor antagonist. Endothelin is a potent vasoconstrictor, making antagonists of clinical interest for the treatment of conditions associated with vasospasm, such as subarachnoid hemorrhage (SAH) and hypertension. Bosentan is a dual endothelin receptor antagonist effective in the treatment of pulmonary arterial hypertension (PAH), the first of the class to make it to market. Bosentan is an orally available, competitive antagonist of both the ETA and ETB receptor subtypes with a Ki of 4.7 nM for ETA and a Ki of 95 nM for ETB.
in vitro
a study was performed in vitro to measure the influence of bosentan on the angiogenic performance of dermal microvascular endothelial cells (mvecs) and to detect the capacity of bosentan in offsetting the antiangiogenic effects of systemic sclerosis sera. it was found that bosentan significantly increased cell viability and offset the antiangiogenic effects of systemic sclerosis sera on dermal mvecs. [2]
in vivo
a study was conducted to investigate the effect of bosentan on plasma leptin level after myocardial infarction in wistar rats. after oral administration of bosentan once daily at the dose of 100 mg/kg for 2 days, concentration of leptin in plasma significantly increased. this finding revealed that bosentan played an crucial role on regulating leptin concentration in ischemic cardiovascular pathology. [1]
IC 50
inhibiting endothelin receptor a and b with an ic50 of 15.1 ± 1.6 μm in p388/dx cells.
