  Chiral 6-aryl-furo[2,3-d]pyrimidin-4-amines as EGFR inhibitors

  摘要：

  Epidermal growth factor receptor inhibitors are of importance in cancer therapy and possibly in the management of pain. Herein, we report a structure-activity relationship study with 29 new 6-aryl-furo [2,3-d]pyrimidin-4-amines, involving modification of the 4-amino group and 6-aryl function. The EGFR activity was especially dependent on having a chiral 4-benzylamino group with correct stereochemistry. Molecular dynamics indicate this to be due to favourable cation-pi interactions. The most active inhibitor identified, equipotent to Erlotinib, was substituted with (R)-1-phenylethylamine at C-4 and a N-1, N-1-dimethyl-1,2-diamine group in para position of the 6-aryl moiety. These new furopyrimidines had a different off-target kinase profile when compared to Erlotinib, and also possessed high activity towards Ba/F3 EGFR(L858R) reporter cells. Further, comparing the EGFR data of the furo[2,3-d]pyrimidin-4-amines with that of the corresponding thieno- and pyrrolopyrimidines concludes the furopyrimidine scaffold to be highly useful for development of new epidermal growth factor receptor antagonists.

• Identification of fused pyrimidines as interleukin 17 secretion inhibitors

  Inhibiting the interleukin 17 pathway is of interest in a number of autoimmune diseases. Herein, 42 fused pyrimidines have been evaluated as interleukin 17 secretion inhibitors using a phenotypic assay with peripheral blood mononuclear cells. 7H-Pyrrolo [2,3-d]pyrimidin-4-amines having aryl groups at C-S or C-6 were found more active than the corresponding thieno- and furopyrimidines. Low cytotoxicity was seen for the most active inhibitors. However, the pyrrolopyrimidines also inhibit interleukin 5 secretion, suggesting that selective interleukin 17 inhibitors should rather be based on furopyrimidines. Profiling towards a panel of 51 kinases and assays towards the retinoic acid receptor-related orphan receptor gamma were performed in order to identify the compounds mode of action.
