Use | AZD-7762 is a synthetic small molecule inhibitor of checkpoint kinases (Chks) with potential chemosensitizing activity. AZD7762 binds to and inhibits Chks, which may prevent cell cycle arrest and subsequent nucleotide excision repair in DNA-damaged tumor cells, resulting in tumor cell apoptosis. This agent may enhance the cytotoxicity of DNA-damaging agents. Chks are protein kinases that regulate either G1/S or G2/M transitions in the cell cycle. In the presence of DNA damage or incomplete DNA replication, Chks become activated and initiate cell cycle arrest to allow DNA repair or the completion of DNA replication. |
In vitro study | AZD7762 is a Chk1 selective inhibitor that inhibits Chk1 phosphorylation of the cdc25C peptide by reversibly binding to the ATP binding site of Chk1 with an IC50 of 5 nM and a Ki of 3.6 nM. AZD7762 induces cell cycle arrest with an EC50 of 0.620 μm, and by blocking cdc25A dependent chk1 degradation and Cyclin A activation, the Camptothecin-induced G2 phase arrest is significantly abolished with an EC50 of 10 nM. 300 nM AZD7762 enhances the anticancer activity of gemcitrate on SW620 and also enhances the anticancer activity of Topotecan on MDA-MB-231 by reducing the GI50 value, from 24.1 nM and 2.25 μm to 1.08 nM and 0.15 μM, respectively. AZD7762 acts on a variety of neuroblastoma cell lines carrying p53 wild-type, p53 mutant, MDM2 addition, or p14 deletion with an IC50 of 82.6 nM to 505.9 nM.

In vivo study | AZD7762 alone at a dose of 25 mg/kg in mice bearing H460-DNp53 xenografts and mice bearing SW620 xenografts showed weak anti-cancer activity, but with Gemcitabine(60 mg/kg). The combined treatment of these two kinds of mice carrying transplanted tumor has strong anti-cancer activity. AZD7762 in combination with gemcitrate (10 mg/kg) inhibited tumor volume in rats bearing H460-DNp53 xenografts in a dose-dependent manner. The combination of AZD7762 (25 mg/kg) and Irinotecan (25 or 50 mg/kg) in mice bearing SW620 xenografts caused total tumor regression. at a dose of 25 mg/kg, AZD7762 showed weak anticancer activity in mice bearing H460-DNp53 xenografts and SW620 xenografts, however, the combination treatment with gemcitrate (60 mg/kg) has strong anti-cancer activity in both mice bearing transplanted tumors. AZD7762 in combination with gemcitrate (10 mg/kg) inhibited tumor volume in rats bearing H460-DNp53 xenografts in a dose-dependent manner.
