| Description: | LY2603618 is a potent and selective inhibitor of Chk1 with an IC50 of 7 nM. |
| In Vivo: | Mice bearing Calu-6 xenografts are treated with 150 mg/kg (IP) Gemcitabine and a single simultaneous 200 mg/kg oral dose of LY2603618. 200 mg/kg of LY2603618 is sufficient to inhibit 85 % of Chk1 autophosphorylation in vivo at 2 h. LY2603618 effectively reduces Gemcitabine-induced phosphorylation on Tlk serine 695 as well, supporting the cited report with a selective chemical inhibitor of Chk1[1]. |
| In Vitro: | LY2603618 is a highly effective inhibitor of multiple aspects of Chk1 biology. LY2603618 is tested against a panel of 51 diverse protein kinases in vitro. With an IC50 of 7 nM for Chk1, LY2603618 is approximately 100-fold more potent against Chk1 than against any of the other protein kinases evaluated (PDK1, IC50=893 nM, others >1000 nM). LY2603618 effectively reduced Chk1 autophosphorylation with an EC50 of 430 nM. Inhibition of Chk1 by LY2603618 also effectively abrogated the G2/M DNA damage checkpoint in cells treated with DNA damaging agents. Treatment of cells with LY2603618 produced a cellular phenotype similar to that reported for depletion of Chk1 by RNAi. Inhibition of intracellular Chk1 by LY2603618 results in impaired DNA synthesis, elevated H2A.X phosphorylation indicative of DNA damage and premature entry into mitosis[1]. Treatments of the SK-N-BE(2) cells with variable concentrations of LY2603618 results in dose-dependent inhibition of cell growth determined by MTT assays with an IC50 of 10.81 µM[1]. |
