摘要:
A series of compounds with quinazoline scaffold were designed, synthesized and evaluated as novel potent 5-HT2A receptor ligands. N-(4-Chlorophenyl)-2-(piperazin-1-yl)quinazolin-4-amine (5o) has a K-i value of 14.04 +/- 0.21 nM, with a selectivity more than 10,000 fold over 5-HT1A receptors (D-1 and D-2-like receptors). The functional assay showed that this compound is an antagonist to 5-HT2A receptor with an IC50 value of 1.66 mu M. (C) 2015 Elsevier Ltd. All rights reserved.
