Urea Transporter

UT-B-IN-1 is a reversible, competitive inhibitor targeting the urea transporter-B (UT-B) with IC50 values of 10 nM for human and 25 nM for mouse UT-B. It demonstrates low toxicity and high selectivity for UT-B over UT-A isoforms. UT-B-IN-1 significantly increases urine output and reduces urine osmolality in murine models, making it a valuable tool for research into diuretic mechanisms and kidney function studies.

PU-48 is a selective inhibitor of urea transporters A (UT-A), exhibiting an IC50 of 0.32 μM. This compound demonstrates significant diuretic activity in mouse models while showing minimal cytotoxicity. PU-48 presents a valuable tool for investigating renal physiology and has potential applications in the development of diuretic therapies.

Butibufen is an orally active non-steroidal compound that primarily targets cyclooxygenase enzymes. It exhibits significant analgesic and antipyretic properties, making it a valuable tool for the study of pain and fever mechanisms. This compound is applicable in research focused on inflammation and related pathological conditions.

UTA1inh-D1 is a selective inhibitor of the UT-A1 and UT-B urea transporters, exhibiting IC50 values of 3.8 μM and 15 μM, respectively. This compound shows potential in the study of refractory edema conditions, including congestive heart failure and cirrhosis. Its unique mechanism of action makes it a valuable tool for exploring urea transport modulation in various pathological contexts.

UTA1inh-A1 is a selective inhibitor of urea transporters UT-A1 and UT-B, demonstrating IC50 values of 3.3 μM and 16 μM, respectively. This compound is primarily utilized in research focused on urea transport and its implications in diuretic therapy. UTA1inh-A1 aids in elucidating the physiological roles of urea transporters and their potential as therapeutic targets for urea-related conditions.

UTA1inh-C1 is a selective inhibitor of the urea transporter UT-A, demonstrating an IC50 of 4.2 μM. This compound effectively modulates urea transport, making it a valuable tool for studying renal physiology and urea homeostasis. Its application in research can help elucidate the role of UT-A in various physiological processes and the impact of urea transport dysregulation in pathological conditions.
