Novel Mixed-Type Inhibitors of Protein Tyrosine Phosphatase 1B. Kinetic and Computational Studies.
The Atlas of Diabetes reports 415 million diabetics in the world, a number that has surpassed in half the expected time the twenty year projection. Type 2 diabetes is the most frequent form of the disease; it is characterized by a defect in the secretion of insulin and a resistance in its target organs. In the search for new antidiabetic drugs, one of the principal strategies consists in promot...
متن کاملProtein Tyrosine Phosphatase 1B Inhibitors: Catechols
As most intracellular signaling takes place via cascades of phosphorylation and dephosphorylation of tyrosines, protein tyrosine phosphatases have emerged as new and promising targets. Among them, protein tyrosine phosphatase 1B (PTP1B) negatively regulates insulin signaling by dephosphorylation of key tyrosine residues within the regulatory domain of the β-subunit of the insulin receptor, ther...
متن کاملPharmacophore modeling for protein tyrosine phosphatase 1B inhibitors.
A three dimensional chemical feature based pharmacophore model was developed for the inhibitors of protein tyrosine phosphatase 1B (PTP1B) using the CATALYST software, which would provide useful knowledge for performing virtual screening to identify new inhibitors targeted toward type II diabetes and obesity. A dataset of 27 inhibitors, with diverse structural properties, and activities ranging...
متن کاملDesign, Synthesis and Biological Evaluation of Stilbene Derivatives as Novel Inhibitors of Protein Tyrosine Phosphatase 1B.
By imitating the scaffold of lithocholic acid (LCA), a natural steroidal compound displaying Protein Tyrosine Phosphatase 1B (PTP1B) inhibitory activity, a series of stilbene derivatives containing phenyl-substituted isoxazoles were designed and synthesized. The structures of the title compounds were confirmed by ¹H-NMR, 13C-NMR and HRMS. Activities of the title compounds were evaluated on PTP1...
متن کاملMolecular docking and high-throughput screening for novel inhibitors of protein tyrosine phosphatase-1B.
High-throughput screening (HTS) of compound libraries is used to discover novel leads for drug development. When a structure is available for the target, computer-based screening using molecular docking may also be considered. The two techniques have rarely been used together on the same target. The opportunity to do so presented itself in a project to discover novel inhibitors for the enzyme p...
