DNA-PK-IN-4

DNA-PK-IN-4 (WO2021209055A1, compound 27), an imidazolinone derivative compound, is a highly effective inhibitor of DNA-PK, specifically targeting DNA-PKcs activity. By inhibiting DNA-PKcs, the compound significantly impairs tumor DNA repair mechanisms and triggers apoptosis in cells. With its potential application in cancer research, DNA-PK-IN-4 holds promise for further investigation [1].
