Application

CLP257 has been used as a K+- Cl- cotransporter 2 (KCC2) enhancer in human neuron culture.

Biochem/physiol Actions

CLP257 is a selective K+-Cl− cotransporter KCC2 activator that restored impaired Cl− transport in neurons with reduced KCC2 activity. Apparently, CLP257 modulates plasmalemmal KCC2 protein turnover post-translationally.
In streptozotocin treated rats, by activating a K+- Cl- cotransporter 2 (KCC2) in the arginine-vasopressin neuron, CLP257 mediates γ-aminobutyric acid (GABA)ergic excitation. It is however inactive with KCC1, KCC3 and KCC4.

Diabetes mellitus (DM) is associated with increased plasma levels of arginine-vasopressin (AVP), which may aggravate hyperglycemia and nephropathy. However, the mechanisms by which DM may cause the increased AVP levels are not known. Electrophysiological recordings in supraoptic nucleus (SON) slices

Approximately half of people infected with HIV (PWH) exhibit HIV-associated neuropathology (neuroHIV), even when receiving combined antiretroviral therapy. Opiate use is widespread in PWH and exacerbates neuroHIV. While neurons themselves are not infected, they incur sublethal damage and GABAergic disruption

The K(+)-Cl(-) cotransporter KCC2 is responsible for maintaining low Cl(-) concentration in neurons of the central nervous system (CNS), which is essential for postsynaptic inhibition through GABA(A) and glycine receptors. Although no CNS disorders have been associated with KCC2 mutations
