Synthesis and biological evaluation of (R)-N-(diarylmethylthio/sulfinyl)ethyl/propyl-piperidine-3-carboxylic acid hydrochlorides as novel GABA uptake inhibitors
摘要:
A series of new (R)-1-(2-diarylmethylthio/sulfinyl) ethyl-pipei-idine-3-carboxylic acid hydrochlorides 5a-d/6a-d and (R)-1(3-diarylmethylthio) propyl-piperidine-3-carboxylic acid hydrochlorides 5'a-d were synthesized and evaluated as gamma-aminobutyric acid uptake inhibitors through cultured cell lines expressing mouse GAT1. Biological screening results demonstrated that the compounds 6a-d with diarylmethylsulfinyl ethyl side chain show more potent GAT-1 inhibitory activities than 5a-d/5'a-d with diary]methylthio ethyl/propyl moieties. Some of them, such as 6a, exhibited excellent inhibitions of [3 H]-GABA uptake in cultured cells, which is 496-fold higher than (R)-nipecotic acid and 11.5 times less than tiagabine. The synthesis and structure-activity relationships are discussed. (c) 2007 Elsevier Ltd. All rights reserved.
