NSAIDS AS MODULATORS OF CATION CHANNELS: FENAMATES REPURPOSING IN CHANNELOPATHIES

open access: yesChemMedChem, Accepted Article.
Cationic ion channels are transmembrane proteins that regulate the flux of cations (potassium, sodium, and calcium) across cell membrane, playing a pivotal role in many cellular functions. Disruptions of their activity can lead to the so‐called genetic or acquired channelopathies, a heterogeneous group of diseases that affect multiple human systems ...
