Application Notes:
LY2603618 is a potent (IC50 = 7nM) and selective (>1000x over Chk2) Checkpoint kinase 1 (Chk1) inhibitor.1 Chk1 is an important regulator of the DNA damage response - combination treatment of LY2603618 with other chemotherapeutic agents significantly increased tumor growth inhibition when compared to chemotherapeutic alone.2,3,4 LY2603618 caused a dramatic suppression of cell growth in MCF-7 and MDA-MB-231 human breast cancer cells via Chk1 inhibition induced upregulation of replication stress caused by oncogenes.5
