Abstract

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 H4 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 hH4R Ki 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 μM. In order to discuss structure-activity relationships molecular modeling and docking studies were undertaken.
