Yellow Solid

Selective Na+/H+ antiporter inhibitor. Selectively enhances the excretion of sodium ions without causing an increase in excretion of potassium ions

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.

ChEBI: Ethylisopropylamiloride is a member of the class of pyrazines that is amiloride in which the amino substitutent of the pyrazine ring that is adjacent to the chloro substituent has been substituted by an ethyl group and by an isopropyl group. It has a role as an anti-arrhythmia drug, a neuroprotective agent and a sodium channel blocker. It is a member of guanidines, an aromatic amine, an organochlorine compound, a tertiary amino compound, a member of pyrazines and a monocarboxylic acid amide. It is functionally related to an amiloride.
