chk1 in 2

CHK1-IN-2 is an inhibitor of checkpoint kinase 1 (CHK1; IC50: 6 nM).

FLT3/CHK1-IN-2 (Compound 30) is a dual inhibitor targeting FLT3 and CHK1, with IC50 values of 25.63 nM for CHK1, 16.39 nM for FLT3-WT, and 22.80 nM for FLT-D835Y. It displays favorable oral pharmacokinetic properties and kinase selectivity. FLT3/CHK1-IN-2 is applicable in acute myeloid leukemia (AML) research.

GDC-0425 (RG-7602) is an orally administered, selective small molecule inhibitor of checkpoint kinase 1 (ChK1), used in research on various malignancies [1] [2].

p53 Stabilizer 2 (Compound 17a16) is a p53 stabilizing agent. It can induce S-phase arrest and apoptosis in both p53-functional and p53-deficient cancer cells. Additionally, p53 Stabilizer 2 triggers mitochondrial stress and activates two immune checkpoint pathways: NA-PKcs dependent p53 stabilization and the ATR-Chk1 axis activation. It also inhibits tumor growth in p53-deficient xenograft models.

Potent Chk2 inhibitor (IC50 = 3 nM). Shows >63-fold selectivity for Chk1 over Chk2 and a panel of 84 other kinases. Inhibits Chk2 activation in response to etoposide-induced DNA damage in HT29 cells. Blocks ionizing radiation-induced apoptosis of mouse thymocytes. Caldwell et al (2011) Structure-based design of potent and selective 2-(quinazolin-2-yl)phenol inhibitors of checkpoint kinase 2.

Jaceosidin has anti-oxidative activity. Jaceosidin has anti-inflammatory activity, also a microglial inhibitor with anti-neuroinflammation activity. aceosidin has anticancer activity, modulates the ERK/ATM/Chk1/2 pathway, leading to inactivation of the Cd

Ziptide, a peptide substrate, is recognized by several serine/threonine protein kinases, such as MAPK activated protein kinase 2 (MAPKAPK2), MAPKAPK3, MAPKAPK5, checkpoint kinase 1 (Chk1), AMP-activated protein kinase (AMPK), and calcium/calmodulin-dependent protein kinase II (CamKII). It serves as a tool in evaluating CamKII activity for the development of inhibitors.

Compound PROTAC-2, also known as PROTAC Chk1 degrader-1, is a potent degrader of Chk1, exhibiting a DC50 of 1.33 μM. It is utilized in cancer research [1].

Phosphorylated CHKtide is a synthetic peptide substrate derived from CDC25C, phosphorylated by CHK1/CHK2 as part of one of the DNA repair pathways. It is utilized in assays for cell cycle checkpoint kinases 1 and 2 (CHK1/CHK2), as well as for salt-inducible kinase (SIK).
