Bioactivity | Levobetaxolol is a potent and high affinity β-adrenergic antagonist with IC50 values of 33.2, 2970, 709 nM for guinea pig atrial β1, tracheal β2 and rat colonic β3 receptors, respectively. Levobetaxolol reduces IOP (intraocular pressure). Levobetaxolol exhibits a micromolar affinity for L-type Ca21-channels. Levobetaxolol decreases the effects of ischaemia/reperfusion injury in rats. Levobetaxolol has the potential for the research of glaucoma[1][2]. |
Invitro | Levobetaxolol shows a higher affinity at cloned human β1 and β2 receptor with Ki values of 0.76, 32.6 nM, respectively[1].Levobetaxolol inhibits functional activities in cells expressing human recombinant β1 and β2 receptors with Kb values of 6, 39 nM, respectively[1]. |
