Synthesis and structure–activity relationships of a series of benzazepine derivatives as 5-HT2C receptor agonists
摘要:
To identify potent and selective 5-HT2C receptor agonists, a series of novel benzazepine derivatives were synthesized, and their structure-activity relationships examined. The compounds were evaluated for their 5-HT2C, 5-HT2A, and 5-HT2B receptor binding affinity and intrinsic activity for the 5-HT2C and 5-HT2A receptors. Among these compounds, 6,7-dichloro-2,3,4,5-tetrahydro-1H-3-benzazepine (6) was effective in a rat penile erection model when administered po, which is a symptom of the serotonin syndrome reflecting 5-HT2C receptor activation. Moreover, compound 6 was characterized as a partial agonist of 5-HT2A receptors; therefore, it had little effect on the cardiovascular system. (C) 2007 Elsevier Ltd. All rights reserved.

was found in both the 2(1H)- and 4(3H)-pyrimidinone series and was most prominent in analogues containing either an electron-withdrawing or -donating substituent in the para position of the phenoxy ring. Significant antiulcer activity was observed only in the 2(1H)-pyrimidinone series among three closely related analogues. One of these, 5-(m-methylphenoxy)-2(1H)-pyrimidinone (3), exhibited more potent
