Biochem/physiol Actions

LY2603618 (LCI-1) is a potent and selective checkpoint kinase 1 (Chk1) inhibitor (IC50 = 7 nM) that produces a cellular phenotype identical to that reported upon Chk1 depletion by RNAi. LY2603618 prevents doxorubicin-induced Chk1 autophosphorylation (IC50 = 52 nM; HeLa), allowing cells to traverse the G2/M checkpoint and proceed into mitosis with unresolved replicated chromosomes. LY2603618 renders mutant p53, but not wild-type, HT-29 colon cancer cells more sensitive to gemcitabine both in vitro and in mice in vivo.

Chondrosarcomas are malignant cartilage tumors that are relatively resistant towards conventional therapeutic approaches. Kinase inhibitors have been investigated and shown successful for several different cancer types. In this study we aimed at identifying kinase inhibitors that inhibit the survival of

Resistance to standard chemotherapy agents remains a major obstacle for improving treatment outcomes for acute myeloid leukemia (AML). The Bcl-2-selective inhibitor ABT-199 has demonstrated encouraging preclinical results, drug resistance remains a concern. Mcl-1 has been demonstrated to contribute to ABT-199
