  Discovery of Tyk2 inhibitors via the virtual site-directed fragment-based drug design

  摘要：

  In this study, we synthesized compound 12 with potent Tyk2 inhibitory activity from FBDD study and carried out a cell- based assay for Tyk2/STAT3 signaling activation upon IFN alpha 5 stimulation. Compound 12 completely suppressed the IFN alpha 5-mediated Tyk2/STAT3 signaling pathway as well as the basal levels of pSTAT3. Stimulation with IFN alpha/beta leads to the tyrosine phosphorylation of the JAK1 and Tyk2 receptor-associated kinases with subsequent STATs activation, transmitting signals from the cell surface receptor to the nucleus. In conclusion, the potency of compound 12 to interrupt the signal transmission of Tyk2/STAT3 appeared to be equivalent or superior to that of the reference compound. (C) 2015 Elsevier Ltd.

  N-Alkylhydrazones of aliphatic ketones in the synthesis of 1,3,4-trisubstituted non-symmetric pyrazoles

  摘要：

  Reactions of N-alkylhydrazones of aliphatic ketones with the Vilsmeier-Haack reagent (DMF-POCl3) were evaluated as a promising approach toward the synthesis of trisubstituted non-symmetric pyrazoles. It was found that either 1,3,4-trialkylpyrazoles or 1,3-dialkylpyrazole-4-carbaldehydes could be obtained in these transformations in high yields (72-83%), in a regioselective manner.
