生物活性
Clazosentan (Ro 61-1790) is a selective endothelin A (ET A ) receptor antagonist. Clazosentan inhibits ET-1-mediated vasoconstriction. Clazosentan prevents cerebral vasospasm, vasospasm-related cerebral infarction.
性状
Solid
体外研究(In Vitro)
Clazosentan (0.1 μM) inhibits the ETA receptor in cerebral arteries.Clazosentan is a substrate of the organic anion-transporting polypeptide (OATP) 1B1/1B3. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
Clazosentan (10 μM, 0.05?mL/kg, intracisternal injection) inhibits the contractile responses to ET-1 in rats.
Clazosentan (10 mg/kg, s.c.) inhibits IL-33-induced hypernociception in mice. has not independently confirmed the accuracy of these methods. They are for reference only.
