This study focuses on the design, synthesis, molecular modeling and biological evaluation of a novel group of alkyl-1,3,5-triazinyl-methylpiperazines. New compounds were synthesized and their affinities for human histamine H receptor (hHR) were evaluated. Among them, 4-(cyclohexylmethyl)-6-(4-methylpiperazin-1-yl)-1,3,5-triazin-2-amine (14) exhibited hHR affinity with a K of 160 nM and behaved as antagonist in functional assays: the cellular aequorin-based assay (IC = 32 nM) and [S]GTPγS binding assay (pK = 6.67). In addition, antinociceptive activity of 14in vivo was observed in Formalin test (in mice) and in Carrageenan-induced acute inflammation test (in rats).

Pharmaceutical discharge to the environment is of concern due to its potential adverse effects on aquatic species. It is estimated that around 40% of pharmaceuticals target G protein-coupled receptors (GPCRs). The transforming growth factor- (TGF) shedding assay was applied to measure the antagonistic activities of pharmaceuticals against human GPCRs.

Analysis of structure-kinetic relationships (SKR) can contribute to an improved understanding of receptor-ligand interactions. Here, fragment (4-(2-benzylphenoxy)-1-methylpiperidine) was used in different fragment growing approaches to mimic the putative binding mode of the long residence time (RT) ligands olopatadine, acrivastine, and levocetirizine at the histamine H receptor (HR). SKR analyses reveal that introduction of a carboxylic acid moiety can increase RT at HR up to 11-fold.

Working memory processes and the histamine-3 receptor in schizophrenia: a [C]MK-8278 PET-fMRI study.

Psychopharmacology (Berl)

Rationale: Working memory impairment is a prominent feature of schizophrenia which predicts clinical and functional outcomes. Preclinical data suggest histamine-3 receptor (H3R) expression in cortical pyramidal neurons may have a role in working memory, and post-mortem data has found disruptions of H3R expression in schizophrenia.

Objectives: We examined the role of H3R in vivo to elucidate its role on working memory impairment in schizophrenia.
