- Synthesis of new 1,2,3-benzotriazin-4-one-arylpiperazine derivatives as 5-HT(1A) serotonin receptor ligands
-
A series of novel 1,2,3-benzotriazin-4-one derivatives was prepared and evaluated as ligands for 5-HT receptors. Radioligand binding assays proved that the majority of the novel compounds behaved as good to excellent ligands at the 5-HT(1A) receptor, some of which were selective with respect 5-HT(2A) and 5-HT(2C) receptors. Six analogues (1a, 2a, 2b, 2c, 2e and 2i) were selected and further evaluated for their binding affinities on D1, D2 dopaminergic and α1-, α2-adrenergic receptors. A o-OCH3 derivative (2e) bound at 5-HT(1A) sites with subnanomolar affinity (IC50=0.059 nM) and shows high selectivity over all considered receptors and may offer a new lead for the development of therapeutically efficacious agents.

- Synthesis and trazodone-like pharmacological profile of 1- and 2--propyl>benzotriazoles
-
A series of 1- and 2--propyl>benzotriazoles were prepared and evaluated for their trazodone-like pharmacological profile; as preliminary pharmacological screening, the compounds were tested for their antiserotonergic, antiadrenergic and antihistaminic in vitro activity as well as for their analgesic in vivo action.Structure-activity relationships showed that among the synthesized compounds, the analogues bearing on the 4-piperazine nitrogen either an unsubstituted phenyl ring or a 2- or 3-chloro phenyl moiety show a pharmacological profilesimilar to that of the antidepressant trazodone. benzotriazoles / antiserotonergic / antiadrenergic / antihistaminic/ analgesic
