Chris;Mathieu, Suzanne;McClure, Andrea;Stoll, Vincent S.;Wetter, Jill;Mankovich, John A.;Hajduk, Philip J.;Vasudevan, Anil;Stoffel, Robert H.;Sun, Chaohong research published 《 Development of Orally Efficacious Allosteric Inhibitors of TNFα via Fragment-Based Drug Design》, the research content is summarized as follows. Tumor necrosis factor α (TNFα) is a soluble cytokine that is directly involved in systemic inflammation through the regulation of the intracellular NF-κB and MAPK signaling pathways. The development of biol. drugs that inhibit TNFα has led to improved clin. outcomes for patients with rheumatoid arthritis and other chronic autoimmune diseases; however, TNFα has proven to be difficult to drug with small mols. Herein, we present a two-phase, fragment-based drug discovery (FBDD) effort in which we first identified isoquinoline fragments that disrupt TNFα ligand-receptor binding through an allosteric desymmetrization mechanism as observed in high-resolution crystal structures. The second phase of discovery focused on the de novo design and optimization of fragments with improved binding efficiency and drug-like properties. The 3-indolinone-based lead compound 12 (I) presented here displays oral, in vivo efficacy in a mouse glucose-6-phosphate isomerase (GPI)-induced paw swelling model comparable to that seen with a TNFα antibody.

Diaz-Peralta, Lucero;Razo-Hernandez, Rodrigo Said;Pastor, Nina;Santiago, Angel;Guevara-Salazar, Juan Alberto;Fernandez-Zertuche, Mario research published 《 1,4-Disubstituted-1,2,3-triazole GABA Analogues: Synthesis, In-Vitro Evaluation, Quantum QSAR and Molecular Docking against Pseudomonas fluorescens GABA-AT》, the research content is summarized as follows. The synthesis of a new series of γ-aminobutyric acid (GABA) analogs was reported where the nitrogen at the γ-position contained in a 1,4-disubstituted-1,2,3-triazole ring system. The triazole ring system was assembled by the Cu(I)-catalyzed alkyne-azide 1,3-dipolar cycloaddition (CuACC) protocol. Two compounds were identified two active compounds with 43 and 59% inhibition resp. A descriptive quantum QSAR study was carried out to correlate this activity with the structural changes in the GABA scaffold. The inhibitory activity of the compounds was related to the electronic properties of the triazole ring and substituents. The interaction with P. fluorescens GABA-aminotransferase (GABA-AT) was evaluated by mol. docking, using a homol. model of the biol. target. One compound showed the best interaction energy, the thiophene- substituted triazole, with a value that correlates well with the exptl. inhibition results. The triazole ring is determinant for a proper orientation for interaction with the GABA-AT enzyme. In addition, the mol. docking revealed the importance of a hydrophobic pocket near the PLP prosthetic group and how this pocket can be used to improve the inhibitory activity of GABA analogs. Human GABA-AT mol. docking studies of these analogs showed their great potential as competitive inhibitors of this enzyme.

Exploration of the positions amenable for substitution on a nonaminoacidic Ca_vα2δ-1 scaffold allowed the identification of favorable positions for the attachment of NET pharmacophores. Among the patterns explored, attachment of the 2-ethylamino-9-methyl-6-phenyl-6,7,8,9-tetrahydro-5H-pyrimido[4,5-e][1,4]diazepin-5-one framework to the meta-position of the Ph ring of the 3-methylamino-1-phenylpropoxy and 3-methylamino-1-thienylpropoxy moieties provided dual compounds with excellent NET functionality. Alternative bicyclic frameworks were also explored, and some lead mols. were identified, which showed a balanced dual profile and exhibited good ADMET properties.
