Notes: Furosemide-d5 is intended for use as an internal standard for the quantification of furosemide (Item No. 17273) by GC- or LC-MS. Furosemide is a loop diuretic and an inhibitor of the Na+/K+/2Cl- (NKCC) cotransporters, NKCC1 and NKCC2 (Kis = ~10 µM for both).{23244,28297} In vivo, furosemide (0.1 mg/kg, p.o.) increases diuresis in beagle dogs.{52809} Furosemide (30 mg/kg) reduces ventricular collagen deposition and fibrosis in a rat model of dilated cardiomyopathy.{52810} It is also an inhibitor of carbonic anhydrase I (CAI), CAII, and CAIII (Kis = 0.052-0.065 µM) and organic ion transporter 1 (OAT1; Ki = 9.5 µM), as well as a GABAA receptor antagonist.{23242,29296,29298}
