Biochem/physiol Actions

Compound 19 (C19) is a small molecule that directly targets TRPM4 TwinF domain and blocks its interaction with GluN2A/GluN2B (NR2A/NR2B) I4 domain. C19 prevents NMDAR/TRPM4 interaction-dependent excitotoxicity (death protection EC50 = 1.1 μM 24 h post 10-min exposure of primary murine hippocampal neurons to 20 μM NMDA) without affecting, and even enhancing, NMDAR-mediated essential functions.

Excitotoxicity induced by NMDA receptors (NMDARs) is thought to be intimately linked to high intracellular calcium load. Unexpectedly, NMDAR-mediated toxicity can be eliminated without affecting NMDAR-induced calcium signals. Instead, excitotoxicity requires physical coupling of NMDARs to TRPM4. This interaction is
