ATM inhibitors in cancer radiotherapy: Mechanisms, clinical development, and future directions. (PubMed, Eur J Med Chem) - "Inhibitors such as KU-55933, KU-60019, and AZD1390 have shown the potential to sensitize cancer cells to radiotherapy by impairing DNA repair, thereby enhancing treatment efficacy...Currently, none have gained approval from the FDA or EMA, but six candidates, AZD1390, AZD0156, ZN-B-2262, SYH2051, WSD0628 and M3541 are in clinical trials, often as adjuncts to radiotherapy or in combination with PARP inhibitors. Their safety and effectiveness, however, are still under investigation. This review synthesizes ATM's dual roles and the therapeutic promise of targeting ATM in cancer radiotherapy."

Small Molecular Inhibitors That Target ATM for Drug Discovery: Current Research and Potential Prospective. (PubMed, J Med Chem) - "Specifically, AZD1390, WSD0628, SYH2051, and ZN-B-2262 are under investigation in clinical studies pertaining to glioblastoma multiforme and advanced solid tumors, respectively. In this Perspective, we encapsulate the structure, biological functions, and disease relevance of ATM. Subsequently, we concentrate on the design concepts and structure-activity relationships (SAR) of ATM inhibitors, delineating potential avenues for the development of more efficacious ATM-targeted inhibitors."

An ATM inhibitor: ZN-B-2262 in combination with radiation /ADCs containing topoisomerase inhibitors for the treatment of solid tumors (AACR 2024) - "Therapeutic efficacy, as measured by tumor growth inhibition (TGI), was evaluated using ZN-B-2262 in combination with DS-1062 (Trop2 ADC), irinotecan or RT in MDA-MB-468 triple negative breast cancer (TNBC), SW620 colorectal cancer, and Fadu head and neck squamous cell carcinoma (HNSCC) subcutaneous xenograft murine models, respectively. ZN-B-2262, in combination with ADCs containing topoisomerase inhibitors, (e.g., Dato-Dxd), or RT, is expected to be a best-in-class (possibly first-in-class) compound, for the treatment of solid tumors. In particular, ZN-B-2262 should demonstrate improved PK and minimal inter-patient PK variability compared to current ATM clinical candidates since ZN-B-2262 is not an AO substrate."
