Abstract: Protein tyrosine phosphatases (PTPs) belong to a large family of important regulatory enzymes involved in vital mammalian signaling pathways. Selective inhibitors of PTPs are highly valuable from a therapeutic standpoint given their association with various pathological conditions. One such target is PTP-1B which has previously been linked to diabetes and cancer. However, developing a selective inhibitor against PTP-1B has proven to be daunting because the enzyme shares a high degree of structural homology with TC-PTP, an essential PTP involved in modulating immune functions. To address this challenge, a series of organoruthenium complexes was developed to bind at the PTP substrate-binding site while simultaneously target the peripheral structural space. By capitalizing on the potential difference in the structural environment proximal to the active site between different PTPs, selectivity toward PTP-1B over TC-PTP was improved, paving the way for organoruthenium complexes as selective PTP-1B metalloinhibitors. © 2012 American Chemical Society.
