Gastric cancer is a common malignant tumor with high incidence and mortality. The overexpression of Human epidermal growth factor receptor 2 (HER2) is associated with increased metastatic potential and poor clinical outcome in gastric cancer. Despite the proven clinical response rates of approved HER2-targeted therapies, including Trastuzumab combined with chemotherapy, their limited long-term clinical benefits and inevitable disease progression still pose significant challenges to the clinical treatment of gastric cancer.

The phosphate group on the 1,2,9,9a-tetrahydrocyclopropa[c]benz[e]indol-4-one (CBI) portion of the compounds confers enhanced solubility and stability in aqueous solutions. In the presence of phosphatases, these compounds convert into active DNA-alkylating agents.
