Prexasertib (LY2606368) is a small molecule checkpoint kinase inhibitor, mainly active against CHEK1, with minor activity against CHEK2. This causes induction of DNA double-strand breaks resulting in apoptosis. It was developed by Eli Lilly but the company announced in 2019 it was dropping prexasertib from active development,^[1] although clinical trials continue. Research continues into the efficacy of prexasertib in treatment of acute myeloid leukemia, myelodysplastic syndrome, rhabdomyosarcoma, and medulloblastoma.^[2]
