DNA-PK-IN-6, a robust DNA-PK inhibitor, effectively hampers the activity of DNA-PKcs, thereby significantly impairing the DNA repair mechanism in tumors and instigating apoptosis in cells. Additionally, DNA-PK-IN-6 amplifies the responsiveness of tumor tissues to radiotherapy, overcomes the challenge of drug resistance, and augments its inhibitory impact on a diverse range of solid and hematological tumors[1].
DNA-PK-IN-2 is a highly effective inhibitor of DNA-dependent protein kinase (DNA-PK), which is a complex enzyme composed of Ku70 Ku80 heterodimer and DNA-PK catalytic subunit (DNA-PKcs). With its potential applications in cancer research, DNA-PK-IN-2 demonstrates promise as a valuable tool for studying cancer diseases [1].
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].
