Background:

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 Ki values of 0.02, 0.5, 2.4, and 0.42 μM, respectively[1],[2] It less effectively inhibits NHE4 (IC50 ≥10 μM).[1] EIPA is commonly used at a concentration of 5-10 μM to inhibit cellular HNE activity.[3],[4]
