产品描述 | ICI 118,551 hydrochloride (ICI 118551 hydrochloride) is a highly selective β2 adrenergic receptor antagonist (Kis: 0.7, 49.5, and 611 nM for β2, β1, and β3 receptors). |
靶点活性 | β1-adrenoceptor:49.5 nM (ki), β2-adrenoceptor:ki:0.7nM , β3-adrenoceptor:611 nM (ki) |
体外活性 | ICI 118551 (10 μM) induces a prominent vasorelaxation of norepinephrine (NE)-precontracted PA but not AO [2]. ICI 118551 inhibits cAMP accumulation in IMCD cells (IC50: 1.7 μM) [1]. In the failing human heart, ICI 118551 has significant effects on beat duration, with time-to-peak contraction and time-to-90% relaxation reduced compared with basal contraction. Negative Inotropic Effect of ICI 118551 Is Not cAMP-Related. Overexpression of β2AR in rabbit myocytes enhances the negative inotropic effects of ICI 118551 [3]. |
体内活性 | ICI 118551 (0.2 mg/kg) injected into the jugular vein of the mice, strongly reduces systolic pressure in the pulmonary circuit but not systemic arterial pressure in vivo[2]. |
