MK-1775 is a potent and selective Wee1 inhibitor with IC50 of 5.2 nM.

ZN-c3 is an orally active, highly potent and selective Wee1 inhibitor (IC50=3.9 nM). ZN-c3 can be used for the research of cancer.

Debio 0123 (Debio0123) is a potent, orally available, and highly selective Wee1 kinase inhibitor with IC50 of 0.8 nM, Ki of 0.1 nM.Debio 0123 is highly selective to Wee1 on 465 selected kinases in a cellfree system, does not inhibit Plk1 and Plk2, as also reported in recent publications for AZD1775.Debio 0123 exhibits in vitro growth inhibition activity in a broad number of human cancer cell lines (IC50= 0.109 to 7.08 uM).Debio 0123 prevent CDC2 / Cdk1 phosphorylation, induces γH2AX and enhances phosphorylation of histone H3.Debio 0123 induces apoptosis through mitotic catastrophe following cell cycle progression despite accumulation of unrepaired DNA damage both in vitro and in vivo.

Wee1 Inhibitor II is a potent, selective, ATP-binding site-targeting inhibitor of Wee1 with IC50 of 59 nM, 590-fold selectivity over the related checkpoint kinase Chk1 (IC50=35 uM).

LEB-03-146 is a WEE1 DUBTAC (deubiquitinase-targeting chimera) linking AZD1775 (Adavosertib) to the OTUB1 recruiter EN523 through a PEG2 linker. LEB-03-146 shows significant WEE1 stabilization in HEP3B hepatoma cancer cells.

Pomalidomide-C3-adavosertib is a rapid and selective Wee1 degrader (IC50=3.58 nM). Pomalidomide-C3-adavosertib shows anti-cancer cell proliferation activity, and induces apoptosis.
