Name	CHK1-IN-3

Description	CHK1-IN-3 is a Checkpoint Kinase 1 (CHK1) inhibitor with an IC50 of 0.4 nM[1].
Related Catalog	Research Areas >> Cancer Signaling Pathways >> Cell Cycle/DNA Damage >> Checkpoint Kinase (Chk)
Target	Chk1:0.4 nM (IC50)
In Vitro	CHK1-IN-3 effectively inhibites the growth of malignant hematopathy cell lines especially Z-138 (IC50: 0.013 µM) and displays low affinity for hERG (IC50 > 40 µM)[1].
In Vivo	CHK1-IN-3 significantly suppresses the tumor growth in Z-138 cell inoculated xenograft model as a single agent with body weight unaffected[1].
