CLP257 (CLP-257) is a potent, selective K+-Cl- cotransporter KCC2 activator with EC50 of 616 nM; displays selectivity for KCC2 over other KCC family members, NKCC1 and GABAA receptors, and a panel of 55 other receptors; restores impaired Cl(-) transport i

DRAinh-A250 is a specific inhibitor of Cl-/anion exchanger SLC26A3 (DRA), fully and reversibly inhibits SLC26A3-mediated Cl- exchange with HCO3-, I-, and thiocyanate (SCN-) with IC50 of ~0.2 uM.

IAA-94 is an indanyloxyacetic acid blocker of epithelial chloride channels.

VU0463271 is a potent KCC2 antagonist, with an IC50 of 61 nM.

Picrotoxinin, a potent convulsant, is a chloride channel blocker. Picrotoxinin is a noncompetitive GABAA receptor antagonist, which negatively modulates the action of GABA on GABAA receptors.

Fenamic acid is a chloride channel blocker.

Endovion (NS 3728, SCO-101) is an potent anion channel inhibitor that blocks the Volume Regulated Anion Channels (VRAC).

CLC-2-IN-AK42 (CLC-2 inhibitor AK42, AK42) is a potent, specific small-molecule inhibitor of voltage-gated chloride channel CLC-2 with IC50 of 17 nM (human CLC-2).AK42 displays unprecedented selectivity (>1,000-fold) over CLC-1, the closest CLC-2 homolog, and no off-target engagement a diverse panel of 61 CNS receptors, channels, and transporters expressed in brain tissue.AK-42 binds to an extracellular vestibule above the channel pore. AK-42 is almost three orders-of-magnitude more potent than MCFA, demonstrates high potency (IC50=14 nM for rat CLC-2) in manual patch-clamp experiments on CHO cells transiently transfected with rat CLC-2.AK-42 inhibits hyperpolarization-activated current in hippocampal cells, attenuates steady-state currents and eliminated relaxation currents in recorded neurons.AK-42 is a powerful tool for investigating CLC-2 neurophysiology.

DFBTA is an orally active, potent and little brain penetrated ANO1 (Calcium-activated chloride channel anoctamin-1) inhibitor, with an IC50 of 24 nM. DFBTA shows analgesic efficacy for inflammatory pain.

T16A(inh)-C01 is an inhibitor of TMEM16A (ANO1). T16A(inh)-C01 blocks chloride channel mediated by ANO1 with an IC50 of 8.4 μM, without interfering with calcium signaling.
