    Monoacid-based PTP1B inhibitors with improved physiochemical properties have been investigated. A (2-hydroxy-phenoxy) acetic acid-based phosphotyrosyl mimetic has been linked with an optimized second arylphosphate binding site ligand to produce compound 20 with low micromolar potency against PTP1B, good selectivity over TCPTP (20-fold) and high cell permeability in the Caco-2 system.
