Biological Activity

Description GSK2193874 is an orally active, potent, and selective blocker of transient receptor potential vanilloid 4 (TRPV4) with IC50 values of 0.04 and 0.002 μM for hTRPV4 and rTRPV4, respectively.
Targets
rTRPV4 [1]
(Cell-free assay)		 hTRPV4 [1]
(Cell-free assay)
0.002 μM 0.04 μM
In vitro
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 GSK2193874 dose-dependently prevents the cellular contraction and detachment induced by TRPV4 activation with GSK1016790[2].
Cell Research Cell lines Stably transfected hTRPV4 HEK cells (CG27) and HUVECs
Concentrations 1-30 nM(extracellularly); 0.03-10 uM(intracellularly)
Incubation Time --
Method

TRPV4 HEK cells were pretreated with GSK2193874, extracellularly (1-30 nM) by application to the bathing solution, or intracellularly (0.03-10 uM) by inclusion in the pipette solution. Ramp currents were elicited between -60 and +60 mV and peak outward current at +60 mV was assessed after TRPV4 activation with GSK634775 (100 nM) added to the bath. In HUVECs, ramp currents were elicited between -80 and +80 mV and measured at + 60 mV, and the TRPV4 activator GSK1016790 (30 nM) was bath applied to activate TRPV4 followed by GSK2193874 (300 nM). 
In Vivo
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. 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, GSK2193874 pretreatment inhibits the formation of pulmonary edema and enhanced arterial oxygenation. TRPV4 blockade with GSK2193874 provides protection against the development of pulmonary edema and the resulting deficits in arterial oxygenation in HF models in vivo. GSK2193874 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].

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
