WEE1-IN-3 is a potent Wee1 kinase inhibitor with an IC50 of <10 nM. WEE1-IN-3 has anticancer activities[1].
WEE1-IN-3 (example 1) inhibits cancer cell growth with IC50 values of 100-1000 nM and <100 nM for SW480 cells and H23 cells, respectively[1].WEE1 kinase plays a role in the G2-M cell-cycle checkpoint arrest for ?Να repair before mitotic entry. Normal cells repair damaged DNA during GI arrest. Cancer cells often have a deficient G i-S checkpoint and depend on a functional G2-M checkpoint for DNA repair. WEE1 is overexpressed in various cancer types[1].
