Biological Activity for Bumetanide

Bumetanide is a loop diuretic that inhibits the Na⁺/2Cl^-/K⁺ (NKCC) cotransporter. More potent than furosemide (Cat. No. 3109). Bumetanide improves electrophysiological, pathological and cognitive deficits in APOE4 knock-in mice. RNA sequencing of neurons derived from APOE4 induced pluripotent stem cell (iPSC) shows Bumetanide reverses Alzheimer's disease transcriptomic signatures.
