LY2606368 (Prexasertib) is a small-molecule Chk-1 inhibitors invented by Array and being developed by Eli Lilly and Company. Lilly is responsible for all clinical development and commercialization activities. LY2606368 is advancing in Phase 2 clinical trials for cancer. Prexasertib preferentially binds to and inhibits CHK1 and, to a lesser extent, inhibits CHK2. Chk-1 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, Chk-1 blocks cell cycle progression in order to allow for repair of damaged DNA, thereby limiting the efficacy of chemotherapeutic agents. Inhibiting Chk-1 in combination with chemotherapy can enhance tumor cell death by preventing these cells from recovering from DNA damage.

Route of Administration: Intravenous
In a functional assay, LY2606368 (PREXASERTIB) potently abrogated the G2–M checkpoint activated by doxorubicin in p53-deficient HeLa cells with an EC50 of 9 nmol/L. LY2606368 did inhibit DNA damage-induced CHK2 autophosphorylation with an IC50 of less than 31 nmol/L. 100 nmol/L LY2606368 did not inhibit PMA-stimulated RSK but instead weakly stimulated phosphorylation of S6 on serines 235/236. LY2606368 was broadly antiproliferative with IC50 values typically <50 nmol/L in the most sensitive cell lines with a minority of cell lines showing considerable resistance with IC50's >1,000 nmol/L
