-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.

+== Function ==
+[https://www.uniprot.org/uniprot/PTN1_HUMAN PTN1_HUMAN] Tyrosine-protein phosphatase which acts as a regulator of endoplasmic reticulum unfolded protein response. Mediates dephosphorylation of EIF2AK3/PERK; inactivating the protein kinase activity of EIF2AK3/PERK. May play an important role in CKII- and p60c-src-induced signal transduction cascades. May regulate the EFNA5-EPHA3 signaling pathway which modulates cell reorganization and cell-cell repulsion.<ref>PMID:21135139</ref> <ref>PMID:22169477</ref>

+== Publication Abstract from PubMed ==
+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.
