描述 | ICI 118551 (Hydrochloride) is a highly selective β2 adrenergic receptor antagonist. ICI 118551 inhibits cAMP accumulation by 50% with IC50 of 1.7 μM in IMCD cells[3].ICI 118551 decreased contraction in ventricular myocytes from failing human hearts by 45.3+/-4.1% but had little effect in nonfailing hearts. ICI 118551 effectively acts as an agonist at the G(i)-coupled beta(2)AR(adrenoceptor), producing a direct negative inotropic effect[4]. Moreover,ICI 118551 evoked a decrease of vascular tone in large pulmonary arteries and reduced the sensitivity of pulmonary arteries toward different contracting agents, eg, norepinephrine, serotonin, or endothelin[5]. |
