Mechanism of Action

Targets/IC₅₀/Ki	rTRPV4 ^[1] (Cell-free assay) 0.002 μM hTRPV4 ^[1] (Cell-free assay) 0.04 μM
In vitro	GSK2193874 is profiled against TRP channels and is selective against TRPV1, TRPA1, TRPC3, TRPC6, and TRPM8 (IC50 > 25 μM)^[1]. Treatment of human umbilical vein endothelial cells (HUVECs) with this compound dose-dependently prevents the cellular contraction and detachment induced by TRPV4 activation with GSK1016790^[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, this compound shows no blood pressure or heart rate effect in rats when dose up to 30 mg/kg. It demonstrates to has the ability to improve pulmonary functions in a number of heart failure models^[1]. In both acute and chronic HF models, this compound pretreatment inhibits the formation of pulmonary edema and enhanced arterial oxygenation. TRPV4 blockade with this chemical provides protection against the development of pulmonary edema and the resulting deficits in arterial oxygenation in HF models in vivo. This compound preserves endothelial cell integrity and inhibits endothelial TRPV4 currents while providing protection from formation of pulmonary edema in isolated lungs and in HF models^[2].
