摘要:
Within the constantly growing number of histamine H-4 (H4R) receptor ligands there is a large group of azine derivatives. A series of novel compounds in the group of 4-methylpiperazine-1,3,5-triazine-2-amines were designed and obtained. Considered structures were modified at the triazine 6-position by introduction of variously substituted arylethenyl moieties. Their affinities to histamine H-4 receptors were evaluated in radioligand binding assays with use of Sf9 cells, transiently expressing human H4R. Pharmacological studies results allowed to identify 4-[(E)-2-(3-chlorophenyl)etheny1]-6-(4-methylpiperazin-1-y1)-1,3,5-triazin-2-amine (K-i = 253 nM) as the most potent compound in the present series.
