| In vitro | Methods: U2OS-EFC cells were treated with AMG-548 (0.01-0.1 μM) to investigate its ability to mediate Wnt-3a-induced hDvl2 mobility shift. Results: AMG-548 inhibited hDvl2 displacement at micromolar concentrations. [2] |
| In vivo | Experimental data showed that AMG-548 exhibited differentiated pharmacokinetic characteristics in different animal models: the elimination half-life (t1/2) in rats was 4.6 hours, while in canine models it was extended to 7.3 hours. In terms of bioavailability (F value), the compound reached 62% in rats, while it was relatively low at 47% in dogs. These Results indicate that AMG-548 has significant species differences, and its metabolic clearance rate and absorption efficiency vary significantly between different animal models. [1] |
