11504691 Trout L, Corboz MR, Ballard ST: Mechanism of substance P-induced liquid secretion across bronchial epithelium. Am J Physiol Lung Cell Mol Physiol. 2001 Sep;281(3):L639-45.

The anion channel blockers diphenylamine-2-carboxylate (DPC) and 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB) inhibited > 90% of substance P-induced liquid secretion, whereas DIDS had no effect.

The stilbene derivative diiso-thiocyanato-stilbene-disulphonic acid (DIDS) and the diphenylamine-2-carboxylate analogue 5-nitro-2-(3-phenylpropylamino)-benzoate (NPPB) caused a dose-dependent, reversible flicker block of the small conductance and significantly reduced the macroscopic current flow through the channel. 6.
In addition, the regulation of these channels by neurokinin-1 (NK-1) receptor agonists and G proteins was studied. 2.

This stimulatory effect of submucosal SP was abolished by furosemide, diphenylamine-2-carboxylate and Cl-free medium, but not by amiloride.

Substance P (SP), neurokinin A (NKA), neurokinin B (NKB), [Sar9, Met (O2) 11]-SP (SMSP), senktide, [beta Ala8]-NKA (4-10) and neuropeptide gamma (NP gamma) all stimulate secretory responses in rat descending colon mucosa under voltage clamp conditions.

11159013 Fortner CN, Lorenz JN, Paul RJ: Chloride channel function is linked to epithelium-dependent airway relaxation. Am J Physiol Lung Cell Mol Physiol. 2001 Feb;280(2):L334-41.

We previously reported that substance P (SP) and ATP evoke transient, epithelium-dependent relaxation of mouse tracheal smooth muscle.
In perfused mouse tracheas, the responses to SP and ATP were both inhibited by the Cl- channel inhibitors diphenylamine-2-carboxylate and 5-nitro-2-(3-phenylpropylamino) benzoate.

Furthermore diphenylamine-2-carboxylic acid (DPC, 0.1 mM in the external fluid), an inhibitor of Cl- channels, decreased the effect of the peptide on SCC by 48%.
