WZ4003 is a highly specific protein kinase inhibitor of NUAK kinases.

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].

WZ4003 helps to repress the migration of cells. It also prevents cell proliferation.
