Application

T16Ainh-A01 has been used as an inhibitor of transmembrane protein 16A (TMEM16A).

Biochem/physiol Actions

T16Ainh-A01 is a selective TMEM16A calcium-activated chloride channel inhibitor that strongly inhibits chloride current in salivary gland cells. T16Ainh-A01 poorly inhibited total CaCC current in intestinal and airway epithelial cells, but blocked mainly an initial, agonist-stimulated transient chloride current. T16Ainh-A01 does not alter cytoplasmic calcium and has little effect on CFTR Cl- conductance.
