T16Ainh-A01 is a potent inhibitor of TMEM16A Chloride channel, inhibiting TMEM16A-mediated chloride currents (IC50 of 1 μM),and functions as a calcium-activated chloride channel (CaCC).
T16Ainh-A01 (0.3-30μM) can significantly reduce the inward and outward components of IClCa and inhibit IClCa in RUICC without significantly affecting L-type Ca2+ current[1]. T16Ainh-A01 (10 μM) inhibits nearly completely TMEM16A chloride current (induced by 275 nM free calcium in the pipette) at all voltages, indicating a voltage-independent block mechanism[2].
