structure-based design and discovery of the isothiazolidinone (IZD) heterocycle as a mimic of phosphotyrosine (pTyr) has led to the identification of novel IZD-containing inhibitors of protein tyrosine phosphatase 1B (PTP1B). The structure-activity relationships (SARs) of peptidic IZD-containing inhibitors of PTP1B are described along with a novel synthesis of the aryl-IZD fragments via a Suzuki coupling

Structure-based design led to the discovery of novel (S)-isothiazolidinone ((S)-IZD) heterocyclic phosphotyrosine (pTyr) mimetics that when incorporated into dipeptides are exceptionally potent, competitive, and reversible inhibitors of protein tyrosine phosphatase 1B (PTP1B). The crystal structure of PTP1B in complex with our most potent inhibitor 12 revealed that the (S)-IZD heterocycle interacts
