Biological Activity
[Description]:
Olodaterol (BI1744) hydrochloride is a selective, long acting β2-adrenoceptor (β2-AR) agonist (EC50=0.1 nM and pKi= 9.14 for human β2-adrenoceptor, respectively). Olodaterol can be used for chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis[1][2][3].

β2 adrenoceptor:0.1 nM (EC50)
[In Vitro]
Olodaterol hydrochloride (0.1~10 nM; fibroblasts) interferes with FGF-induced phosphorylation of signalling cascades[2]. Olodaterol hydrochloride (0.001~10 nM; fibroblasts) attenuates growth factor-induced motility and proliferation[2]. Olodaterol hydrochloride (0.001~1000 nM; 0.5 hours; fibroblasts) increases intracellular cAMP in a concentration-dependent manner. Olodaterol hydrochloride (0~10 nM; 0.5 hours; fibroblasts) concentration-dependently inhibits the PICP increase with maximal efficacy of 70 % at 10 nM. Olodaterol hydrochloride has a subnanomolar affinity for the β2-AR (pKi=9.14) and is selective for this receptorin comparison with the β1-AR and β3-AR subtypes[2]. Western Blot Analysis[2] Cell Line: Fibroblasts Concentration: 0.1~10 nM Incubation Time: Result: Interfered with FGF-induced phosphorylation of signalling cascades. Cell Proliferation Assay[2] Cell Line: Fibroblasts Concentration: 0.001~10 nM Incubation Time: Result: Attenuated growth factor-induced motility and proliferation.
[In Vivo]
Olodaterol (1 mg/kg; inhal.; 21 days) accelerats body weights recovery back to control levels (at day 21) and attenuats TGF-β-induced lung fibrosis[2]. Olodaterol (0.1~3 μg/kg; inhal.; 5 hours) induces a dose-dependent bronchoprotection[3]. Olodaterol (0.3 and 0.6 μg/kg; inhal.; 24 hours) induces a maximal bronchoprotection of approximately 60 % after 0.5 hours[3]. Animal Model: Lung fibrosis C57BL/6 mice Dosage: 1 mg/mL Administration: Inhal.; 21 days Result: Accelerated body weight recovery back to control levels (at day 21) and attenuated TGF-β-induced lung fibrosis. Animal Model: Guinea Pigs Dosage: 0.1~3 μg/kg Administration: Inhal.; 5 hours Result: Induced a dose-dependent bronchoprotection. Animal Model: Dogs Dosage: 0.3 and 0.6 μg/kg Administration: Inhal.; 24 hours Result: Olodaterol (0.6 μg/kg) induced a maximal bronchoprotection of approximately 60 % after 0.5 h.
