Furosemide is a potent and orally active inhibitor of Na⁺/K⁺/2Cl^- (NKCC) cotransporter, NKCC1 and NKCC2. Furosemide is also a GABA_A receptors antagonist and displays 100-fold selectivity for α6-containing receptors than α1-containing receptors. Furosemide acts as a loop diuretic and used for the study of congestive heart failure, hypertension and edema.

Furosemide is also a GABA_A receptors antagonist and displays 100-fold selectivity for α6-containing receptors than α1-containing receptors. Furosemide acts as a loop diuretic and used for the study of congestive heart failure, hypertension and edema^[2].

In Vitro

Furosemide (500 μM; 72-96 hours) significantly changes the proliferation rates in MKN45 cells (the poorly differentiated human gastric adenocarcinoma cell line). however, it has no effects on MKN28 cells (the moderately differentiated human gastric adenocarcinoma cell line). The growth rate of MKN45 cells is larger than that of MKN28 cells^[4].
Furosemide (10 μM, 30 μM, 100 μM; 45 min exposure) significantly decreases cation channel activity and [Ca(2+)](i) in human erythrocytes drawn from healthy individuals. Tert-butylhydroperoxide similarly enhances the non-selective cation channels activity, increases [Ca(2+)](i) and triggered cell membrane scrambling, however, the effects is significantly blunted by furosemide again^[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Furosemide (intraperitoneal injection; 100 mg/kg; single dose) is injected after kanamycin (KM) (1000 mg/kg) to creat a deaf mouse model in C57BL/6 mouse. After injection, hearing loss and cochlear hair cell damage are evaluated on day 1, day 2 and day 3, respectively. The hearing is markedly deteriorated even from the next day (Day-1 group), OHCs (outer hair cell) morphology of apical, middle and basal turns are disorganized in mice on day3^[3].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.5 mg/mL (7.56 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (7.56 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
