WZ4003
WZ4003 is a potent and selective inhibitor of NUAK1 and NUAK2 with IC50 values of 20 and 100 nM, respectively [1].
NUAK family SNF1-like kinase-1 (NUAK1) and the related NUAK2 belong to the AMP-activated protein kinase (AMPK) family and are activated by liver kinase B1 (LKB1) tumour suppressor protein kinase [1].
WZ4003 is a potent and selective NUAK1/2 inhibitor. In HEK-293 cells, WZ4003 inhibited the phosphorylation of myosin phosphate-targeting subunit 1 (MYPT1), which was phosphorylated by NUAK1 at Ser445. In HEK-293 cells overexpressing inhibitor-resistant NUAK1[A195T], WZ4003 didn’t inhibit the phosphorylation of MYPT1 at Ser445. In mouse embryonic fibroblasts (MEFs), WZ4003 significantly inhibited migration in a wound-healing assay and inhibited MEFs proliferation. In a cell invasion assay, WZ4003 inhibited the invasive potential of U2OS cells [1]. In U2OS cells, WZ4003 (10 μM) inhibited phosphorylation of MYPT1 and reduced the cells in S-phase by 50%. Also, WZ4003 prevented cells from entering into mitosis [2].

Kinase assays |
In vitro activities of purified GST–NUAK1 were measured using Cerenkov counting of incorporation of radioactive 32P from [γ-32P]ATP into Sakamototide substrate peptide. Reactions were carried out in a 50 μl reaction volume for 30 min at 30°C and reactions were terminated by spotting 40 μl of the reaction mix on to P81 paper and immediately immersing in 50 mM orthophosphoric acid. Samples were washed three times in 50 mM orthophosphoric acid followed by a single acetone rinse and air drying. The kinase-mediated incorporation of [γ-32P]ATP into Sakamototide was quantified by Cerenkov counting. |

Applications |
WZ4003 impaired the invasive potential of U2OS cells in a 3D cell invasion assay to the same extent as NUAK1 knockdown, which indicates that WZ4003 will serve as useful chemical probes to delineate the biological roles of the NUAK kinases. |
