Biological Activity

Description Furosemide is a potent NKCC2 (Na-K-2Cl symporter) inhibitor, used in the treatment of congestive heart failure and edema.

Furosemide reversibly alters the responses to tones and clicks of the chinchilla basilar membrane in hair cells, causing response-magnitude reductions that are largest (up to 61 dB, averaging 25-30 dB) at low stimulus intensities at the characteristic frequency (CF) and small or nonexistent at high intensities and at frequencies far removed from CF. Furosemide also induces response-phase lags that are largest at low stimulus intensities (averaging 77 degrees) and are confined to frequencies close to CF. [1]

Furosemide concentration- and time-dependently increases the formation of nitric oxide andprostacyclin. Furosemide leads to an enhanced release of kinins into the supernatant of the cells. [2]

Furosemide reversibly suppresses low Ca2+-induced epileptiform activity in hippocampus proper and blocks or significantly reduces different types of epileptiform discharges in the low Mg2+ model and the 4-aminopyridine model. [3]

Furosemide significantly inhibits cell growth in MKN45 cells, but not in MKN28 cells. Furosemide diminishes cell growth by delaying the G(1)-S phase progression in poorly differentiated gastric adenocarcinoma cells, which show high expression and activity of NKCC, but not in moderately differentiated gastric adenocarcinoma cells with low expression and NKCC activity.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
