UT-B-IN-1

UT-B-IN-1 (UTBINH-14) is a reversible, competitive, and selective inhibitor of the urea transporter-B (UT-B) with IC50 values of 10 nM and 25 nM for human and mouse UT-B, respectively. It exhibits low toxicity and superior selectivity against UT-B compared to UT-A isoforms, enhances urine production, and decreases urine concentration in mice, making it suitable for research on diuretic mechanisms.
