PD0166285 is a potent Wee1 and Chk1 inhibitor with activity at nanomolar concentrations.PD0166285 is a novel G2 checkpoint abrogator.

BX795 is an effective and selective PDK1 inhibitor (IC50: 6 nM), and its selectivity is 140- and 1600-fold for PDK1 over PKA and PKC in cell-free assays, respectively. Meanwhile, the selectivity for PDK1 is 100-fold than GSK3β.

CHK1-IN-3 is an inhibitor of checkpoint kinase 1 (CHK1; IC50: 0.4 nM).

ZNL 02-096 (Pomalidomide-C3-adavosertib) is a rapid and selective degrader of Wee1 (IC50=3.58 nM).ZNL 02-096 selectively degrades Wee1 at submolar concentrations without damaging PLK1, a secondary target of AZD 1775.ZNL 02-096 induces degradation of Wee1 and accumulation of DNA damage in MOLT-4 cells in vitro, In vitro in MOLT-4 cells, ZNL 02-096 induced Wee1 degradation, accumulation of DNA damage, cell cycle arrest in G2/M phase and apoptosis.ZNL 02-096 showed anti-proliferative effects in 300 cancer cell lines.

ANI-7 is an activator of the aryl hydrocarbon receptor (AhR) pathway, inhibiting the growth of various cancer cells and selectively inhibiting the growth of MCF-7 breast cancer cells (GI50: 0.56 μM).

CHK1-IN-4 hydrochloride is a potent inhibitor of checkpoint kinase 1 (chk1). CHK1-IN-4 hydrochloride potently inhibits chk1 phosphorylation in the tumor cells. CHK1-IN-4 hydrochloride has anti-tumor activity.
