Background:

VU 0240551 is a small molecule inhibitor of the neuronal K-Cl cotransporter, KCC2 (IC50 = 560 nM for K+ uptake assay in KCC2-overexpressing cells).IC50 value: 560 nM [1]Target: K-Cl cotransporter(KCC2)VU 0240551 exhibits selectivity over the Na-K-2Cl cotransporter, NKCCl. VU 0240551 also inhibits hERG and L-type Ca2+ channels [1]. Herein we report the discovery and SAR of an improved novel antagonist (VU0463271) of the neuronal-specific potassium-chloride cotransporter 2 (KCC2), with an IC(50) of 61 nM and >100-fold selectivity versus the closely related Na-K-2Cl cotransporter 1 (NKCC1) and no activity in a larger panel of GPCRs, ion channels and transporters [2].
