摘要: New long-chain 4-substituted piperazines linked to a thienopyrimidine or quinazoline system were synthesized and tested for their binding properties on human cloned 5-HT1A 5-HT7 serotonin receptors. Some structural modifications, concerning tree main portions, that is, terminal fragment, chain length, aryl substituents, examined. The 2- 3-substituted thienopyrimidinone quinazolinone systems selected as fragment length of four five methylene units was set. Explored substituents phenyl, phenylmethyl, 3- 4-chlorophenyl, 2-ethoxyphenyl. Title compounds showed affinity In particular, 2-ethoxyphenyl derivatives 40 45 displayed Ki values in the nanomolar range both receptors, acting dual ligands.
