AZD-7762 is an inhibitor of checkpoint kinase (CHK) 1 that increases sensitivity to DNA-damaging compounds. AZD-7762 exhibits anticancer chemotherapeutic activity and is currently in clinical trials as a potential treatment for a variety of cancers. In breast cancer and ovarian cancer cells, AZD-7762 inhibits cellular proliferation. In animal models of breast cancer, AZD-7762 inhibits tumor growth and increases survival rates. This compound displays somewhat limited efficacy due to cardiac toxicity.
