Owing to their multifunctional pharmacological profiles (including dual 5-HT1A/5-HT7 action), arylpiperazine derivatives are widely used for treating central nervous system diseases including the depression or neuropathic pain. Herein we describe the design, synthesis and evaluation of biological activity of novel 5-HT7 ligands derived of 2,4,6-triamino-1,3,5-triazine. The studied compounds showed affinity and high selectively towards 5-HT7 receptor with the two most active compounds 34 (Ki = 61 nM), 22 (Ki = 109 nM) showing good metabolic stability and moderate affinity to CYP3A4 isoenzyme. Compound 22 had high hepatotoxicity at a concentration below 50 μM, while compound 34 showed low hepatotoxicity even at a concentration above 50 μM.

A series of chiral 2,3-dichlorophenoxy and 1-naphthyloxy alkylamines were synthesized, and their binding affinities towards 5-HT1D and h5-HT1B receptors were evaluated. In the naphthyloxy series, the (R)-prolinol derivative was the most selective 5-HT1D ligand, while (S)-N-methyl-2-(1-naphthyloxy)propan-1-amine showed the highest selectivity for h5-HT1B. Both compounds performed as 5-HT1D agonists in the isolated guinea pig assay and showed higher analgesic activity than both sumatriptan and the achiral analogue 20b in the mouse hotplate test. Neither ligand displayed any affinity for nicotinic ACh receptors present in mouse brain membranes, thus indicating that their analgesic activity does not arise through interaction with these receptors.
