A Highly Efficient Approach to a Selective and Cell Active PTP1B inhibitors

Contents

Overview

Using an NMR-based fragment screening and X-ray crystal structure-based, assembly, starting with millimolar ligands for both the catalytic site and, the second phosphotyrosine binding site, we have identified a, small-molecule inhibitor of protein tyrosine phosphatase 1B with low, micromolar inhibition constant, high selectivity (30-fold) over the highly, homologous T-cell protein tyrosine phosphatase, and good cellular activity, in COS-7 cells.

Disease

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

About this Structure

1Q1M is a Single protein structure of sequence from Homo sapiens with as ligand. Active as Protein-tyrosine-phosphatase, with EC number 3.1.3.48 Full crystallographic information is available from OCA.
