Targeting the “Undruggable” STAT3 DBD: Free-Energy Perturbation-Guided Design of Covalent Micheliolide Derivatives Targeting Cysteine 367
Pancreatic cancer remains a highly lethal malignancy, largely due to persistent STAT3 signaling that sustains cancer stem cells (CSCs) and drives therapeutic resistance. Conventional inhibitors targeting the conserved SH2 domain of STAT3 have exhibited limited selectivity and efficacy. Here, we report that michelioli...
