PU-48
Based on 1 Customer Validation
PU-48 is a blood-brain barrier-permeable urea transporter (UT) inhibitor with an IC50 of 0.32 μM against rat UT-A. By functionally inhibiting urea transporters (including UT-A subtypes) in the renal inner medullary collecting ducts, PU-48 induces urea-selective diuresis. PU-48 does not alter blood levels of sodium, potassium or chloride ions, nor does it affect the excretion of non-urea solutes. PU-48 shows no significant toxicity in cell or animal models and can be used in edema-related research.

Biologische Aktivität
PU-48 (0.25-4 µg/mL; 24 h) exhibits high plasma protein binding (over 89%) in human plasma, with no concentration-dependent differences across the tested concentrations[2].
PU-48 (10-9-10-4 M; 6 min) potently and specifically inhibits UT-B-mediated urea transport in human, rat, and mouse erythrocytes with IC50 values of 0.21 μM, 0.33 μM, and 2.1 μM, respectively[3].
PU-48 (4 μM; 60 min) inhibits UT-A1-mediated urea transport in UT-A1-expressing Type I MDCK cells with an IC50 of 0.32 μM, which is ~2.8-fold more potent than its inhibition of UT-B-mediated transport in UT-B-expressing Type I MDCK cells (IC50=0.90 μM)[3].
PU-48 (5-80 μM; 72 h) does not exhibit cytotoxicity in Type I MDCK cells at concentrations up to 80 μM after 72 h incubation[3].
PU-48 (10 μM) does not inhibit hERG, NaV1.5, or CaV1.2 channel activity in stably transfected HEK293 cells[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:Type I MDCK cells
-
Concentration:5-80 μM
-
Incubation Time:72 h
-
Result:Did not significantly reduce MDCK cell viability at concentrations up to 80 μM, with viability remaining near 100% relative to controls.
PU-48 (100 mg/kg; s.c.; single dose) induces urea-selective diuresis in both UT-B null and wild-type male C57BL/6 mice without altering electrolyte excretion[3].
PU-48 (3.125-50 mg/kg; s.c.; single dose) induces dose-dependent diuresis in male SD rats at subcutaneous doses of 12.5 and 50 mg/kg, with peak efficacy at 2 h post-administration[3].
PU-48 (50-100 mg/kg; s.c.; every 8 h; 6 days) induces sustained diuresis in male SD rats with twice-daily subcutaneous dosing of 50 mg/kg (first dose 100 mg/kg) for 6 days, without causing electrolyte imbalance or altering renal transporter/aquaporin protein expression[3].
PU-48 (14 g/kg; p.o.; single dose) shows no acute toxicity in 4-week-old male and female CD-ICR mice[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
