Synthesis and Evaluation of a Class of Compounds Inhibiting the Growth of Stromal Antigen 2 (STAG2)-Mutant Ewing Sarcoma Cells.

STAG2 (SA2) is a critical component of the cohesin complex that regulates gene expression and the separation of sister chromatids in cells. Mutations in STAG2 have been identified in over thirty different types of cancers including myeloid leukaemia, non-small cell lung, bladder and Ewing sarcoma. Selectively inhibiting cancer cells lacking of STAG2 is an attractive approach for the cancer therapy. Here we report that a small molecule, StagX1, identified through a high-throughput screening, inhibits the growth of Ewing sarcoma cells possessing mutant STAG2. A new synthetic route to the StagX1 scaffold and new versions of the molecule along with their activity in a cell viability assay are reported. © 2022 Wiley-VCH GmbH.
