Product Description
Information
WNK463 WNK463 is a pan-WNK-kinase inhibitor. It potently inhibits the in vitro kinase activity of all four WNK family members (WNK1, WNK2, WNK3, and WNK4).
Targets
WNK-kinase
In vitro
WNK463 potently inhibited the in vitro kinase activity of all four WNK family members (WNK1, WNK2, WNK3, and WNK4). WNK463 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.
In vivo
In rodent models of hypertension, WNK463 affects blood pressure and body fluid and electrolyte homeostasis. WNK463 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), WNK463 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, WNK463 produced significant and dose-dependent increases in urine output as well as urinary sodium and potassium excretion rates. Orally administered WNK463 also significantly decreasedblood pressure in these hypertensive mice. WNK463 elicited in vivo cardiovascular and renal effects through WNK kinase inhibition.
This compound belongs to the class of organic compounds known as 2-heteroaryl carboxamides. These are compounds containing a heteroaromatic ring that carries a carboxamide group.
