Abstract: 4-(5-Arylidene-2,4-dioxothiazolidin-3-yl)methylbenzoic acids (2) were synthesized and evaluated in vitro as inhibitors of PTP1B and LMW-PTP, two protein tyrosine phosphatases (PTPs) which act as negative regulators of the metabolic and mitotic signalling of insulin. The synthesis of compounds 2 represents an example of utilizing phosphotyrosine-mimetics to identify effective low molecular weight nonphosphorus inhibitors of PTPs. Several thiazolidinediones 2 exhibited PTP1B inhibitory activity in the low micromolar range with moderate selectivity for human PTP1B and IF1 isoform of human LMW-PTP compared with other related PTPs.
