Overview

We have previously reported a novel series of oxalyl-aryl-amino benzoic, acid-based, catalytic site-directed, competitive, reversible protein, tyrosine phosphatase 1B (PTP1B) inhibitors. With readily access to key, intermediates, we utilized a solution phase parallel synthesis approach, and rapidly identified a highly potent PTP1B inhibitor (19, K(i)=76 nM), with moderate selectivity (5-fold) over T-cell PTPase (TCPTP) through, interacting with a second phosphotyrosine binding site (site 2) in the, close proximity to the catalytic site.

Disease

Known diseases associated with this structure: Abdominal body fat distribution, modifier of OMIM:[176885], Insulin resistance, susceptibility to OMIM:[176885]
