Bumetanide
Based on 19 publication(s) in Google Scholar
Bumetanide (Ro 10-6338; PF 1593), a highly potent loop diuretic, is a Na+-K+-Cl+ cotransporter (NKCC) blocker. Bumetanide is a selective NKCC1 inhibitor, but also inhibits NKCC2, with IC50s of 0.68 μM and 4.0 μM for hNKCC1A and hNKCC2A, respectively.

IC50: 0.68 μM (hNKCC1A), 4.0 μM (hNKCC2A)[1]
Bumetanide has inhibitory effects for the two major human splice variants of NKCCs, hNKCC1A, and hNKCC2A [1].
Bumetanide (0.03-100 μM; 5 minutes) inhibits the 86Rb+ uptake in NKCC1A-expressing oocytes in a dose-dependent manner[1].
Bumetanide inhibits NKCC2 isoform B in HEK-293 cells with an IC50 value of 0.54 μM[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Bumetanide also reduces infarct size[3].
Bumetanide shows different half-lives of 21.4 min, 53.8 min, and 137 min following 2 mg/kg, 8 mg/kg, and 20 mg/kg intravenous injection, respectively, in rats[4].

Representative short-circuit current traces (left) and summary graphs (right) from epithelia kept in control conditions, treated with IL-4 or treated with IL-17A/TNF-α. During recordings, CFTRinh-172 (apical, 10 µM) and Bumetanide (basolateral, 100 µM) were added sequentially after stimulation of CFTR with CPT-cAMP. Dotted and dashed lines indicate the baseline for cAMP-activated current and zero current level, as in previous legends. The graphs report the fraction of the cAMP-activated current blocked by CFTRinh-172 (I-172), bumetanide alone (bum) or both compounds together (tot).
