Biological Activity

[Description]:

Azosemide, a sulfonamide loop diuretic, is a potent NKCC1 inhibitor with IC50s of 0.246 µM and 0.197 µM for hNKCC1A and NKCC1B, respectively[1].

[Related Catalog]:

Signaling Pathways >> Membrane Transporter/Ion Channel >> NKCC

Research Areas >> Metabolic Disease

[Target]

IC50: 0.246 µM (hNKCC1A) and 0.197 µM (NKCC1B)[1]

[In Vitro]

Azosemide inhibits the sodium-potassium-chloride-cotransporter human variants hNKCC1A and hNKCC1B[1].

[In Vivo]

Azosemide shows a smaller AUC (81.9% decrease), shorter terminal half-life (50.9% decrease) and MRT (64.1% decrease), faster CL (454% increase), CLR (853% increase) and CLNR (307% increase) for NARs[2]. Animal Model: Male Sprague-Dawley rats (control rats, weighing 310345 g) and NARs (weighing 220315 g) of 9 weeks of age[2] Dosage: 10 mg/kg (Pharmacokinetic Analysis) Administration: Infused over 1 min via the jugular vein (i.v.) Result: Showed a smaller AUC (81.9% decrease), shorter terminal half-life (50.9% decrease) and MRT (64.1% decrease), faster CL (454% increase), CLR (853% increase) and CLNR (307% increase) for NARs.
