Crystal structure of dipeptidyl-peptidase 4 (CD26, adenosine deaminase complexing protein 2) (DPP-IV-WT) complex with bms-767778 AKA 2-(3-(aminomethyl)-4-(2,4- dichlorophenyl)-2-methyl-5-oxo-5,7-dihydro-6h-pyrrolo[3,4- b]pyridin-6-yl)-n,n-dimethylacetamide

FunctionDPP4_HUMAN Cell surface glycoprotein receptor involved in the costimulatory signal essential for T-cell receptor (TCR)-mediated T-cell activation. Acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. Its binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner. Its interaction with ADA also regulates lymphocyte-epithelial cell adhesion. In association with FAP is involved in the pericellular proteolysis of the extracellular matrix (ECM), the migration and invasion of endothelial cells into the ECM. May be involved in the promotion of lymphatic endothelial cells adhesion, migration and tube formation. When overexpressed, enhanced cell proliferation, a process inhibited by GPC3. Acts also as a serine exopeptidase with a dipeptidyl peptidase activity that regulates various physiological processes by cleaving peptides in the circulation, including many chemokines, mitogenic growth factors, neuropeptides and peptide hormones. Removes N-terminal dipeptides sequentially from polypeptides having unsubstituted N-termini provided that the penultimate residue is proline.[1] [2] [3] [4] [5] [6] [7] [8] [9] Publication Abstract from PubMedOptimization of a 5-oxopyrrolopyridine series based upon structure-activity relationships (SAR) developed from our previous efforts on a number of related bicyclic series yielded compound 2s (BMS-767778) with an overall activity, selectivity, efficacy, PK, and developability profile suitable for progression into the clinic. SAR in the series as well as characterization of 2s are described.
