Biological Activity

[Description]:

Oxprenolol (Ba 39089 free base) is an orally bioavailable β-adrenergic receptor (β-AR) antagonist with a Ki of 7.10 nM in a radioligand binding assay using rat heart muscle[1].

Signaling Pathways >> GPCR/G Protein >> Adrenergic Receptor

[Target]

β-adrenoceptor:7.10 nM (Ki)

[In Vitro]

Oxprenolol is lipophilic[3]. Oxprenolol shows permeability rate constant of 1.54 ± 1.54×10-3 cm/h across abdominal human skin[3].

[In Vivo]

Oxprenolol (200 mg/kg/day; p.o.; daily for 3 weeks) produces effective beta-blockade together with peak plasma drug levels within the normal clinical range[2]. Animal Model: Male rats (230 to 300 g body wt) of the Wistar strain[2] Dosage: 200 mg/kg Administration: Administered orally; daily for 3 weeks Result: This dosage produced effective beta-blockade.
