Description: Na+/2Cl-/K+ (NKCC) symporter inhibitor; also GABAA antagonist
Chemical Name: 5-(Aminosulfonyl)-4-chloro-2-([2-furanylmethyl]amino)benzoic acid
Purity: ≥99% (HPLC)
Biological Activity for Furosemide
Furosemide is a loop diuretic that inhibits the Na+/2Cl-/K+ (NKCC) symporter. Also acts as a non-competitive antagonist at GABAA receptors with ~ 100-fold greater selectivity for α6-containing receptors than α1-containing receptors.
Compound Libraries for Furosemide
Furosemide is also offered as part of the Tocriscreen 2.0 Max and Tocriscreen FDA-Approved Drugs. Find out more about compound libraries available from Tocris.
