  • The AMPK inhibitor, WZ4003, and the p38 MAPK inhibitor, SB203580, could inhibit the APN-induced overexpression of CXCL1 and CXCL8 and h-JBMMSCs chemotaxis. After treated with WZ4003 and SB203580, the expression of CXCL1 (A and B) and CXCL8 (C and D) in the cells and supernatants of h-JBMMSCs treated with or without APN was evaluated by the ELISA assay (n = 3; *P < 0.05; **P < 0.01)

    Indicated cells were treated with LPS (200 ng/ml) in the absence or presence of indicated AMPK activators (AICAR [100 μM] and A-769662 [2 μM]) or inhibitors (compound C [200 nM] and WZ4003 [100 nM]) for 24 hours. OCR and ECAR were monitored (n=3, *p < 0.05 versus single LPS group).

Biological Activity

Description WZ4003 is a highly specific NUAK kinase inhibitor with IC50 of 20 nM and 100 nM for NUAK1 and NUAK2 in cell-base assays, respectively, without significant inhibition on 139 other kinases.
NUAK1 [1]
(Cell-free assay)
NUAK2 [1]
(Cell-free assay)
20 nM 100 nM
In vitro

In HEK-293 cells expressing wild-type NUAK1, WZ4003 (3–10 μM) markedly suppresses NUAK1-mediated MYPT1 phosphorylation. Moreover, WZ4003 (10 μM) inhibits MYPT1 Ser445 phosphorylation as well as cell migration, invasion and proliferation to a similar extent as knock out in MEFs or knock down in U2OS cells of NUAK1. [1] WZ4003 also exhibits a high, specific affinity to the L858R/T790M mutant EGFR, while a significantly reduced cellular IC50 against T790M containing Ba/F3 cells. [2]

IC50 determination:

Active GST–NUAK1, GST–NUAK1[A195T] and GST–NUAK2 enzymes are purified using glutathione–Sepharose from HEK-293 cell lysates 36–48 h following the transient transfection of pEBG2T mammalian constructs expressing N-terminal GSTtagged NUAK1, NUAK1[A195T] or NUAK2. For peptide kinase assays, 96-well plates are used, and each reaction is performed in triplicate. Each reaction is set up in a total volume of 50 μL containing 100 ng of NUAK1 (wild-type or A195T mutant) or NUAK2 in 50 mM Tris/HCl (pH 7.5), 0.1 mM EGTA, 10 mM magnesium acetate, 200 μM Sakamototide, 0.1 mM [γ -32P]ATP (450–500 c.p.m./pmol) and the indicated concentrations of inhibitors dissolved in DMSO. After incubation for 30 min at 30°C, reactions are terminated by adding 25 mM (final) EDTA to chelate the magnesium. Then, 40 μL of the reaction mix is spotted on to P81 paper and immersed in 50 mM orthophosphoric acid. Samples are washed three times in 50 mM orthophosphoric acid followed by a single acetone rinse and air drying. The incorporation of [γ -32P]ATP into Sakamototide is quantified by Cerenkov counting. The values are expressed as a percentage of the DMSO control. IC50 curves are developed and IC50 values are calculated using GraphPad Prism software.

  • Cell lines: U2OS cells, and MEFs
  • Concentrations: ~10 μM
  • Incubation Time: 5 days
  • Method: Cell proliferation assays are carried out colorimetrically in 96-well plates using the CellTiter 96 AQueous Non-Radioactive Cell Proliferation Assay kit following the manufacturer’s protocol. Initially, 2000 cells per well are seeded for U2OS cells and 3000 cells per well are seeded for MEFs. The proliferation assays are carried out over 5 days in the presence or absence of 10 μM WZ4003.

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
