Target	IC50: 2.1 μM (TMEM16A)[1], 10 μM (CaCC)[2]
In Vitro	30 μM CaCCinh-A01 and 100 μM tannic acid strongly inhibit CaCC current following ATP stimulation[1]. Calcium-dependent chloride current is reduced by 38±14, 66±10, and 91±1% by 0.1, 1, and 10 μM CaCCinh-A01, respectively. ATP-induced short-circuit currents are reduced by 38±7 and 78±3% at 10 and 30 μM CaCCinh-A01, respectively[2].
Cell Assay	Each well of a 96-well plate is washed three times with PBS (200 μL/wash), leaving 50 μL of PBS. Test compounds (including CaCCinh-A01) (0.5 μL) are added to each well at 25 μM final concentration. After 10 min, 96-well plates are transferred to a plate reader for fluorescence assay. Each well is assayed individually for TMEM16A-mediated I- influx by recording fluorescence continuously (400 ms/point) for 2 s (base line), then 50 μL of a 140 mM I- solution containing 200 μM ATP is added. The initial rate of I- influx is computed from fluorescence data by nonlinear regression[1].
