  Synthesis and evaluation of novel ligands for the histamine H4 receptor based on a pyrrolo[2,3-d]pyrimidine scaffold

  摘要：

  Starting from a known H4R ligand based on a pyrimidine skeleton, a series of novel analogues based on a pyrrolo[2,3-d]pyrimidine scaffold have been prepared. Whereas the original pyrimidine congener shows good affinity at hH(4)R (K-i = 0.5 mu M), its lacks selectivity with a K-i value for the hH(3)R of 1 mu M. Within the newly synthesized pyrrolo[2,3-d]pyrimidines, several congeners show K-i values of less than 1 mu M at the hH(4)R and show a much improved selectivity profile. Therefore, these series represent an interesting starting point for the discovery of novel hH(4)R ligands. (C) 2012 Elsevier Ltd. All rights reserved.
