VU0810464

CAS No. : 2126040-21-7

MCE 站：VU0810464

产品活性：VU0810464 是有效的，选择性的非尿素蛋白门控的内向整流钾通道 (GIRK, Kir3) 激活剂。 VU0810464 对神经元 GIRK1/2 (EC₅₀=165 nM) 和 GIRK1/4 (EC₅₀=720 nM) 神经通道具有纳摩尔效价，并且具有脑部渗透性。

研究领域：Membrane Transporter/Ion Channel

作用靶点：Potassium Channel

In Vitro: 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.

In Vivo: 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 (K_p,uu = 0.83), has a improvement over ML297 (K_p,uu= 0.32). Clearance of VU0810464 is rapid,brain and plasma half-lives is 20 min in a PK study.
