g protein-coupled receptor 68

Ogerin 是选择性 GPR68正向别构调节剂(pEC50:6.83)。它能够抑制小鼠对恐惧记忆的回忆。它对 A2A 受体具有适中的拮抗作用(Ki:220 nM)。对 5-HT2B 受体的拮抗作用较弱(Ki:736 nM)。

ML-252 is a potent, selective inhibitor of the Kv7.2 voltage-gated potassium channel, demonstrating an IC50 value of 69 nM in patch clamp assays. It exists as the (S)-enantiomer, which is significantly more effective than both its (R)-enantiomer counterpart and the racemic mixture, with respective IC50 values of 944 nM and 160 nM. ML-252 exhibits high selectivity for Kv7.2 over other potassium channel subtypes and shows minimal activity against more than 68 G protein-coupled receptors, various transporters, L- and N-type calcium channels, K_ATP, and hERG potassium channels. However, it does inhibit the melatonin MT1 receptor by 61% at a 10 µM concentration.

MS48107 是 G 蛋白偶联受体 68 (GPR68) 的选择性正变构调节剂，对GPR68的选择性高于密切相关的神经递质转运蛋白，质子 GPCR 和 hERG 离子通道。它可以穿越过小鼠的血脑屏障。
