G-quadruplexes (G4s) are four-stranded alternative secondary structures formed by guanine-rich nucleic acids and are prevalent across the human genome. G4s are enzymatically resolved using specialized helicases. Previous studies showed that DEAH-box Helicase 36 (DHX36/G4R1/RHAU), has the highest specificity and affinity for G4 structures.

Clinical trials employing small-molecule MDM2/p53 interaction inhibitors (SMIs) have demonstrated limited activity, underscoring an unmet need for a better approach to target MDM2. KT 253 is a highly potent and selective heterobifunctional degrader that overcomes the MDM2 feedback loop seen with SMIs and induces apoptosis in a range of hematologic and solid tumor lines.
