CLP257 是一种选择性 K⁺-Cl⁻ 共转运蛋白 KCC2 激活剂，EC₅₀ 为 616 nM。CLP257 对 NKCC1，GABAA 受体，KCC1，KCC3 和 KCC4 无活性。CLP257 恢复了 KCC2 活性减弱的神经元 Cl⁻ 转运受损，并减轻了神经性疼痛大鼠的超敏反应。CLP257 在翻译后调节血浆中的 KCC2 蛋白转化。

CLP257 is a selective K-Cl cotransporter KCC2 activator with an EC 50 of 616 nM. CLP257 is inactive against NKCC1, GABAA receptors, KCC1, KCC3 or KCC4. CLP257 restores impaired Cl transport in neurons with diminished KCC2 activity. CLP257 alleviates hypersensitivity in rats with neuropathic pain. CLP257 modulates plasmalemmal KCC2 protein turnover post-translationally.

Solid

EC50: 616 nM (KCC2)

There is no change in [Cl]i in HEK293-cl cells when incubated with CLP257, indicating inactivity on NKCC1, KCC1, KCC3 or KCC4. Oocyte pre-incubation with CLP257 (200 nM) increases KCC2 transport activity by 61%, but causes no change in other CCCs. Functional, dose-dependent antagonism is also observed between CLP257 and the recently characterized KCC2 antagonist VU024055119. CLP257 (50 μM) provokes < 0.2% of the effect of 5 μM muscimol in CHO cells transduced with recombinant α1β2γ2 GABAA receptors, indicating negligible agonist activity of CLP257 on GABAA receptors. has not independently confirmed the accuracy of these methods. They are for reference only.
