Description and Uses

Sodium-hydrogen exchangers (NHE) are involved in maintaining sodium and pH balance in a variety of tissues. They are also known as sodium-hydrogen antiporters and solute carrier family 9 members. 5-(N-ethyl-N-isopropyl)-Amiloride (EIPA) is a potent inhibitor of several NHE isoforms, inhibiting NHE1, NHE2, NHE3, and NHE5 with K_i values of 0.02, 0.5, 2.4, and 0.42 μM, respectively. It less effectively inhibits NHE4 (IC₅₀ ≥10 μM). EIPA is commonly used at a concentration of 5-10 μM to inhibit cellular HNE activity.

5-(N-Ethyl-N-isopropyl)amiloride has been used:

• as a supplement in endothelial cell growth medium to incubate human lung microvascular endothelial cell
• in Pluronic F-127 stock solution for Drosophila larval live-imaging
• in choline chloride solution as an experimental perfusate, to study the effect of Na⁺/H⁺ inhibition on jejunal loop perfusion in vivo
