and evaluated a series of compounds at the human histamineH 4 receptor (H 4R) from which 2-(4-methyl-piperazin-1-yl)-quinoxaline ( 3) was identified as a new lead structure for H 4R ligands. Exploration of the structure-activity relationship (SAR) of this scaffold led to the identification of 6,7-dichloro 3-(4-methylpiperazin-1-yl)quinoxalin-2(1 H)-one (VUF 10214, 57) and 2-benzyl-3-(4-methyl-pip
