ClC-2 currents were inhibited by 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB), diphenylamine-2-carboxylic acid (DPC), and anthracene-9-carboxylic acid (9-AC), with a potency order of NPPB > DPC = 9-AC, but were resistant to stilbene disulfonates.

Finally, we show that the conductance is not blocked by the addition of any of the following compounds to the extracellular solution: anthracene-9-carboxylate (A9C, 1 mmol/l), diphenylamine-2-carboxylate (DPC, 1 mmol/l), 5-nitro-2-(3-phenylpropylamino)-benzoate (NPPB, 100 mumol/l), 4,4'-diisothiocyanato-stilbene-2,2'-disulphonate (DIDS, 100 mumol/l), indanyloxyacetic acid (IAA-94, 100 mumol/l), verapamil (100 mumol/l), glibenclamide (100 mumol/l) and Ba2+ (5 mmol/l).
The properties of the ductal Cl- conductance most nearly resemble those of the ClC-2 channel.

We have previously shown that unstimulated granular duct cells of mouse mandibular gland contain a hyperpolarization-activated Cl- conductance with characteristics resembling the hyperpolarization-activated volume-sensitive Cl- channel (ClC-2).
The current carried by this conductance is attenuated 65% by 1 mmol/l diphenylamine-2-carboxylate but is not affected by 0.1 mmol/l4,4'-diisothiocyanatostilbene-2,2'-disulfonic acid or 0.1 mmol/l glibenclamide.

ICl,hyp was partially inhibited by 1 mM diphenylamine-2-carboxylic acid or 0.1 mM 5-nitro-2-(3-phenylpropylamino)-benzoate, and was completely blocked by Cd2+ (> 300 microM).
We conclude that hyperpolarization-activated Cl- channels similar to those of ClC-2 channels (mammalian homologue of Torpedo chloride channel ClC-0) are present in T84 cells, and that their gating properties are modulated by phosphorylation.
