Biochem/physiol Actions

WNK463 is a high-affinity, ATP-competitive inhibitor against with-No-Lysine (K) kinases (hWNK1/3/4 IC50 = 5/6/9 nM with MBP & 1 μM ATP, hWNK2 IC50 = 1 nM with MBP & 2 μM ATP, hWNK1 IC50 = 41 nM with OSR1 & 0.5 μM ATP; hWNK1/4 KD = 3.71/3.84 by SPR), exhibiting weak affinity against only two other human kinases among a panel of 442. WNK463 downregulates the overexpressed OSR1 phosphorylation level in HEK293 cells (IC50 = 106 nM; 1 hr) and displays in vivo efficacy in rodent hypertension models (1-10 mg/kg in rats p.o., 10 mg/kg in hWNK1 transgenic mice p.o.) with good orally availability (F = 100%/mice & 74%/rats post 1.5 mg/kg p.o.).

Nuclear gene transcription is coordinated with transcript release from the chromatin template and messenger RNA (mRNA) export to the cytoplasm. Here we describe the role of nuclear-localized kinase WNK1 (with no lysine [K] 1) in the mammalian mRNA export pathway

The With-No-Lysine (K) (WNK) kinases play a critical role in blood pressure regulation and body fluid and electrolyte homeostasis. Herein, we introduce the first orally bioavailable pan-WNK-kinase inhibitor, WNK463, that exploits unique structural features of the WNK kinases for both

The With-No-Lysine (WNK) serine/threonine kinase family constitutes a unique and distinctive branch of the kinome. The four proteins of this family (WNK1/2/3/4) are involved in blood pressure regulation, body fluid, and electrolyte homeostasis. Herein, we modeled and analyzed the binding

The with-no-lysine (K) (WNK) signaling pathway to STE20/SPS1-related proline- and alanine-rich kinase (SPAK) and oxidative stress-responsive 1 (OSR1) kinase is an important mediator of cell volume and ion transport. SPAK and OSR1 associate with upstream kinases WNK 1-4, substrates, and

The with-no-lysine (K) WNK kinases are master regulators of the Na+-(K+)-Cl- cotransporters, including the renal-specific NCC and NKCC2 cotransporters. The discovery of WNK463, an orally bioavailable pan-WNK kinase inhibitor that exploits unique structural properties of the WNK catalytic domain to
