    The structure-based design and synthesis of isothiazolidinone (IZD) inhibitors of PTP1B containing imidazoles and imidazolines and their modification to interact with the B site of PTP1B are described here. The X-ray crystal structures of 3I and 4I complexed with PTP1B were solved and revealed the inhibitors are interacting extensively with the B site of the enzyme.
