Urea channel inhibitors (UCIs): A new functional class of aquaretics
نویسندگان
چکیده
Using large-scale small-molecule screening techniques, Li et al. have identified a compound that inhibits the UT-B urea channel. They propose that this or similar compounds could be used as aquaretic agents to increase water excretion without changes in electrolyte excretion. Such compounds would potentially be useful in treatment of hyponatremic disorders. Here we review the physiological basis for the action of urea channel inhibitors in the kidney and assess their clinical potential.

Background and aims: Diabetic nephropathy (DN) is the most common cause of end-stage renal failure which could increase the risk of cardiovascular disease and morbidity and mortality in patients. The aim of this study was to investigate new modalities for treatment of diabetic nephropathy. Methods:This study was a mini-review research to investigate drugs that are used for DN treatment. Resul...
متن کاملUrea Transporter Inhibitors as Novel Diuretics
Urea transporter (UT) proteins, including isoforms of UT-A in kidney tubule epithelia and UT-B in vasa recta endothelia and erythrocytes, play an important role in the urine concentration mechanism by mediated an intra renal urea recycling, suggesting that functional inhibition of these proteins could have therapeutic use as a novel class of diuretic. Recently several classes of UT inhibitors h...

In an elegant example of bench-to-bedside research, a hypothesis that cells in the outflow pathway actively regulate conventional outflow resistance was proposed in the 1990s and systematically pursued, exposing novel cellular and molecular mechanisms of intraocular pressure (IOP) regulation. The critical discovery that pharmacologic manipulation of the cytoskeleton of outflow pathway cells dec...
متن کاملIdentification of quinazolinyloxy biaryl urea as a new class of SUMO activating enzyme 1 inhibitors.
SUMO activating enzyme 1 (SUMO E1) is the first enzyme in sumoylation pathway and an important cancer drug target. However, only a few inhibitors were reported up to now that includes three natural products, semi-synthetic protein inhibitors and one AMP mimic. Here, we report the identification of quinazolinyloxy biaryl urea as a new class of SUMO E1 inhibitors. The most active compound of this...
