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.
