| 产品描述: | VU0810464 is a potent and selective non-ureaG protein-gated inwardly-rectifying potassium channels (GIRK, Kir3) activator. VU0810464 displays nanomolar potency for neuronal (EC50=165 nM) and GIRK1/4 (EC50=720 nM) channels with improved brain penetration |
| 靶点: |
EC50: 165 nM (GIRK 1/2); 720 nM (GIRK1/4 );PotassiumChannel |
| 体外研究: |
VU0810464 (0, 0.1, 0.3, 1, 3, 10, 30 μM) produces a concentration‐dependent response curves of currents in SAN and HPC cells, in addition, VU0810464 is 9‐fold higher potency for Kir3 channel activation in neurons as compared to SAN cells. |
| 体内研究: |
VU0810464 (intraperitoneal injection; 30 mg/kg, 10 mg/kg; 30mg/kg; pre-treated 30 mins) produces a dose-dependent reduction of SIH response in Male C57BL/6J mice. To test if VU0810464 plays it role through Kir3 channel activation, VU0810464 (10 mg/kg) suppresses the SIH response in wild‐ type mice, but has no impact on Kcnj3−/− mice. VU0810464 (intraperitoneal injection ; 30 mg/kg; 15, 30, 45, or 60 min post‐injection) displays a favourable distribution to the brain (Kp,uu = 0.83), has a improvement over ML297 (Kp,uu= 0.32). Clearance of VU0810464 is rapid,brain and plasma half-lives is 20 min in a PK study. Animal Model:Male C57BL/6J mice, Kcnj3−/− siblings female and male C57BL/6J mice Dosage:10 mg/kg; 30mg/kg Administration:Intraperitoneal injection Result:Reduced stress‐induced hyperthermia (SIH), a physiological test of anxiolytic efficacy in wild mice, but had no impact in and Kcnj3 (Girk1) −/− mi |
