GSK2193874 is profiled against TRP channels and is selective against TRPV1, TRPA1, TRPC3, TRPC6, and TRPM8 (IC50>25 μM)[1]. GSK2193874 is a selective, orally active TRPV4 blocker that inhibits Ca2+ influx through recombinant TRPV4 channels and native endothelial TRPV4 currents. In whole-cell patch-clamp studies, GSK2193874 inhibits activation of recombinant TRPV4 currents when applied to the extracellular solution at 3 nM and above but is ineffective at up to 10 μM when applied to the inside of the cell by inclusion in the intracellular pipette solution[2].

Protocol
Rats[2]
Adult male Sprague-Dawley rats (n=7 to 8 per group) are treated with vehicle (6% Cavitron) or GSK2193874 (30 mg/kg per day) via oral gavage for at least 4 days before osmotic challenges. Rats undergo acute and chronic hyper- and hypo-osmotic challenges. Sprague-Dawley rats are administered vehicle (0.9% NaCl, 25 mL/kg), NSC 269420 (30 mg/kg), or hydrochlorothiazide (30 mg/kg) via oral gavage. Urine is then collected over 4 hours followed by blood sampling. Rats recover for 4 days and then receive GSK2193874 (30 mg/kg per day oral gavage) for 5 days before repeating the diuretic challenge.
