Description: Na+/2Cl-/K+ (NKCC) symporter inhibitor
Chemical Name: 3-(Aminosulfonyl)-5-(butylamino)-4-phenoxybenzoic acid
Purity: ≥98% (HPLC)
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.
