Eur J Med Chem 2014; 85:16-26. [PMID: 25076379 DOI: 10.1016/j.ejmech.2014.07.059] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2014] [Revised: 07/11/2014] [Accepted: 07/18/2014] [Indexed: 11/29/2022]
Abstract
A series of new benzazepines with modification on the catecholic fragment were designed. The 8-hydroxyl group, other than the 7-hydroxyl was confirmed crucial to the interaction with the dopamine D1 receptor. Subsequent replacement of the 7-hydroxyl with benzylamino groups was found tolerable. 7-(m-Chlorophenyl)methylamino- and 7-(m- or o-tolyl)methylamino-substituted benzazepines 13b-d displayed Ki values of 270-370 nM at the D1 receptor, which were slightly more potent than that of parent compound 1. In addition, 7-(arylmethyl)amino-benzazepines 13a-c were found possessing high binding affinities less than 10 nM at the 5-HT2A receptor. Among them, the non-substituted 7-benzylamino analogue 13a was the most potent showing a Ki values of 4.5 nM at the 5-HT2A receptor and a 5-HT2A/D1 selectivity of 147.
