Aryl-1,3,5-triazine derivatives as histamine H4 receptor ligands
摘要:
A series of novel 2-amino-4-(4-methylpiperazin-1-yl)-1,3,5-triazine derivatives with different aryl substituents in the 6-position was designed, synthesized and evaluated for histamine H-4 receptor (H4R) affinity in Sf9 cells expressing human H4R co-expressed with G-protein subunits. Triazine derivative 8 with a 6-(p-chlorophenyl) substituent showed the highest affinity with hH(4)R K-i value of 203 nM and was classified as an antagonist in CAMP accumulation assay. This compound, identified as a new lead structure, demonstrated also anti-inflammatory properties in preliminary studies in mice (carrageenan-induced edema test) and neither possessed significant antiproliferative activity, nor modulated CYP3A4 activity up to concentration of 25 mu M. In order to discuss structure activity relationships molecular modeling and docking studies were undertaken. (C) 2014 Elsevier Masson SAS. All rights reserved.
