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.
Potent and selective checkpoint kinase 1 (Chk1) inhibitor that renders mutant p53 cancer cells more sensitive to DNA-damaging agents in vitro and in vivo.

Interference with DNA damage checkpoints has been demonstrated preclinically to be a highly effective means of increasing the cytotoxicity of a number of DNA-damaging cancer therapies. Cell cycle arrest at these checkpoints protects injured cells from apoptotic cell death until
Head and neck squamous cell carcinomas (HNSCCs) coincide with poor survival rates. The lack of driver oncogenes complicates the development of targeted treatments for HNSCC. Here, we follow-up on two previous genome-wide RNA and microRNA interference screens in HNSCC to
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

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
