چکیده
A series of 4-amino-3-[[2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl]thio]-5-(substituted phenyl)[1,2,4]triazoles (5a-f) and the isomeric 4-amino-2-[2-[4-(2-methoxyphenyl)-1piperazinyl]ethyl]-5-(substitutedphenyl)-2,4-dihydro-3H[1,2,4]triazole-3-thiones (6a-f) and a series of 3-[[2-[4-(2-methoxy or 2-nitrophenyl)1-piperazinyl]ethyl]thio]-5-(substituted phenyl)[1,2,4]triazoles (8a-i) were synthesized with the aim of obtaining new selective 5-HT1A ligands, with reduced affinity for the α1-adrenoceptor subtypes. New compounds were tested in radioligand binding experiments where many of them showed a preferential affinity for the 5HT1A receptor.

To obtain drugs which are more selective at benzodiazepine (BZD) receptors, design and synthesis of functionally selective ligands for BZD receptors is the current strategy of our pharmaceutical chemistry department. The affinity of newly synthesized ligands is assessed by radioligand receptor binding assays. Based on our previous studies, 2-phenyl-5-oxo-7-methyl-1,3,4-oxadiazolo[a,2,3]-pyrimid...

Considerable interest has been focused on the triazole structure, which has been known to possess a broad spectrum of biological activities such as antitumor, anti-inflammatory, antimicrobial, antiviral, and anticonvulsant activities. Before this, several heterocyclic compounds containing triazole were synthesized that had shown considerable anticonvulsant activity. As part of our continuous re...
