In vitro
In vitro	WNK463 potently inhibited the in vitro kinase activity of all four WNK family members (WNK1, WNK2, WNK3, and WNK4). This compound also inhibited WNK1-catalyzed phosphorylation of the native WNK substrate, oxidative stress response 1 (OSR1) in a biochemical assay and in human embryonic kidney 293 (HEK293) cells that express exogenous OSR1 and that are activated by sorbitol-mediated osmotic stress^[1].

In Vivo
In vivo	In rodent models of hypertension, WNK463 affects blood pressure and body fluid and electrolyte homeostasis. This compound is orally bioavailable in C57BL/6 mice (100%) and Sprague Dawley rats (74%), with a half-life of 3.6 and 2.1 h, respectively. In spontaneously hypertensive rats (SHRs), this compound administered orally (p.o.) at 1, 3, or 10 mg per kg body weight (mg/kg) p.o. achieved maximum plasma concentration (Cmax) values of 88, 441, and 1,170 nM, respectively. These exposures produced dose-dependent decreases in blood pressure and simultaneous increases in heart rate in conscious SHRs. Moreover, this chemical produced significant and dose-dependent increases in urine output as well as urinary sodium and potassium excretion rates. Orally administered this compound also significantly decreased blood pressure in these hypertensive mice. It elicited in vivo cardiovascular and renal effects through WNK kinase inhibition^[1].
