NSC260594 is a chemical compound that promotes apoptosis by binding to the shallow groove of the Mcl-1 protein and suppressing its expression through down-regulation of Wnt signaling proteins. Additionally, it can identify the G9-G10-A11-G12 RNA tetraloop of HIV, thereby obstructing the attachment of the Gag protein to the 5’-UTR. This compound demonstrates the potential to impede tumor proliferation and is utilized in the study of Triple-negative breast cancers (TNBCs) [1].
