The outward and inward currents were equally inhibited by a carboxylate analogue Cl- channel blocker, 5-nitro-2-(3-phenylpropylamino)-benzoate (NPPB) or diphenylamine-2-carboxylate (DPC) at higher doses (IC50 = 25 for NPPB or 350 microM for DPC).
Arachidonic acid was still effective in the presence of inhibitors of lipoxygenase (nordihydroguaiaretic acid, 10 microM), cyclo-oxygenase (indomethacin, 10 microM) and protein kinase C (polymyxin B, 30 microM).

Diphenylamine-2-carboxylate, Cl-free medium, indomethacin, the phospholipase A2 inhibitor mepacrine, and the methyltransferase inhibitor 3-deazaadenosine reduced the change in ISC, whereas amiloride and the lipoxygenase inhibitor AA-861 did not.

The combined application of a cyclo-oxygenase inhibitor, indomethacin (50 microM), and a lipoxygenase inhibitor, esculetin (100 microM), increased the Cl- current, whereas the administration of a phospholipase A2 inhibitor, mepacrine (100 microM), significantly decreased the whole-cell Cl- current. 6.
Another Cl- channel blocker, 4-acetamido-4'-isothiocyanatostilbene-2,2'-dilsulphonic acid or diphenylamine-2-carboxylate was much less effective. 4.

The response was inhibited by treatment of epithelial cells with diphenylamine-2-carboxylate but not by amiloride.
The increase in Isc induced by the supermatant from eosinophils treated with indomethacin or the lipoxygenase inhibitor AA861 was significantly less than that induced by untreated eosinophils.

The PGD2-induced increase in Isc was not altered by preincubation of cells with autonomic antagonists (phentolamine, propranolol, atropine), the lipoxygenase inhibitor AA-861, the protein kinase C inhibitor H-7, or the Na channel blocker amiloride, but it was inhibited by each of indomethacin, piroxicam, the Cl channel blocker diphenylamine-2-carboxylate, the Cl transport inhibitor furosemide, and Cl-free medium.

The erythromycin-induced decrease in Isc was not altered by amiloride, but it was abolished by bumetanide, diphenylamine-2-carboxylate2, and substitution of Cl in the bathing medium with gluconate (p less than 0.001, in each case).
