Biological Activity for Benzamil

Benzamil is a Na⁺/Ca²⁺ exhanger (NCX) inhibitor (IC₅₀ ~ 100 nM); TRPP3 channel blocker (IC₅₀ = 1.1 μM for inhibition of Ca²⁺-activated TRPP3 channel activity). Also non-selective Deg/ENaC family blocker; reduces mechanosensitivity of colonic afferents. More potent derivative of amiloride (Cat. No. 0890).
