LY-2606368 (Prexasertib) Dihydrochloride
LY2606368 (Prexasertib) is a clinical -stage, potent and selective ATP competitive inhibitor of the CHK protein kinase. It preferentially acts on CHK1 (with a biochemical Ki of 0.9 nM) over CHK2 and RSK (with Ki of 8 nM and 9 nM, respectively). CHK1 is a protein kinase that regulates the tumor cell’s response to DNA damage often caused by treatment with chemotherapy. In response to DNA damage, CHK1 blocks cell cycle progression in order to allow to repair damaged DNA, thereby limiting the efficacy of chemotherapeutic agents. Inhibiting CHK1 in combination with chemotherapy can enhance tumor cell death by preventing these cells from recovering from DNA damage.
