Bioactivity | GSK2193874 is an orally active, potent, and selective TRPV4 antagonist with IC50s of 2 nM and 40 nM for rTRPV4 and hTRPV4[1]. | ||||||||||||
Target | IC50: 2 nM (rTRPV4), 40 nM (hTRPV4) | ||||||||||||
Invitro | 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]. | ||||||||||||
In Vivo | The pharmacokinetic (PK) properties for GSK2193874 are evaluated in both rat and dog and found to have half-lives and oral exposure suitable for oral dosing in chronic animal models (Rat PK: iv CL=7.3 mL/min/kg, po t1/2=10 h, %F=31. Dog PK: iv CL=6.9 mL/min/kg, po t1/2=31 h, %F=53). In addition, GSK2193874 shows no blood pressure or heart rate effect in rats when dose up to 30 mg/kg. GSK2193874 is the first-in-class orally bioavailable TRPV4 inhibitor that demonstrated ability to improve pulmonary functions in a number of heart failure models[1]. GSK2193874 shows low clearance (7.3 mL/min/kg) and good rat oral bioavailability (31%)[2]. | ||||||||||||
