Under isobaric conditions at 75 mmHg, 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB), a chloride channel blocker, reversibly depressed the myogenic constriction with an IC50 of 32.8 +/- 0.52 microM (mean +/- S.E.M., n = 5).

Two I (Cl,swell) blockers, 5-nitro-2-[3-phenylpropylamino] benzoic acid (NPPB) and indanyloxyacetic acid 94 (IAA-94) (both 1 mg/kg), were administered prior to CAO and throughout the 72 h CAR.

In this study, four blockers of anion transporters (ATs) belonging to four different classes of organic acids, including DIDS (4, 4'-diisothiocyanatostilbene-2, 2'- disulfonic acid; a stilbene disulfonic acid), NPPB [(5-nitro-2-(3-phenylpropylamino) benzoic acid; an anthranilic acid)], 9-AC (anthracene-9-carboxylic acid; an aromatic carboxylic acid), and IAA-94 (indanyloxy acetic acid; an indanyloxy alkanoic acid), were tested for their toxicity against the European corn borer (ECB), Ostrinia nubilalis.

Indanyloxyacetic acid 94 (IAA-94, 10 micromol/L) or 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB, 1 micromol/L) was administered before IP or before SI or SI/SR to inhibit Cl- channels.

The Cl (-) channel antagonists 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB), indanyloxyacetic acid-94 (IAA-94) and 4,4'-diisothiocyanostilbene-2,2'-disulfonic acid (DIDS) were found to decrease (P <0.05) the maximum tension generated by rat thoracic aortic segments during stimulation with prostaglandin F (2 alpha) and to shift the concentration-response relationship to the right.

EMBO J. 1999 Oct 15;18(20):5517-27.


VacA-dependent increase of current conduction both in artificial planar lipid bilayers and in the cellular system was effectively inhibited by the chloride channel blocker 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB), while2-[(2-cyclopentenyl-6,7dichloro-2, 3-dihydro-2-methyl-1-oxo-1H-inden-5-yl) oxy] acetic acid (IAA-94) was less effective.

Using a pharmacological toolbox, we show that all drugs that reduced the microglia current (NPPB, IAA-94, flufenamic acid and DIOA) increased the resting cell volume in isotonic solution and inhibited the regulatory volume decrease that followed cell swelling in hypotonic solution.

In the basilar arteries from the New Zealand white rabbits, the role of Cl- flux in serotonin-induced contraction was demonstrated by (i) inhibition of Na+-K+-2Cl- co-transporter (NKCC1) to decreased Cl- influx with bumetanide; (ii) a disabled Cl-/HCO3- exchanger with bicarbonate free HEPES solution; (iii) blockade of Cl- channels using 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB) and indanyloxyacetic acid 94, R-(+)-methylindazone (R-(+)-IAA-94); and (iv) substitution of extracellular Cl- with methanesulfonate acid (113 mmol/L; Cl-, 10 mmol/L).

That current could be blocked by the selective chloride channel blockers 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB) or indanyloxyacetic acid 94 (IAA-94), but only at 100 microM and 1 m M respectively.
