摘要：

A series of novel 3-alkoxy-1,2-dihydro-3H-1,4-benzodiazepin-2-ones (7-15) was synthesized and their in vitro affinity for both the central benzodiazepine receptor (CBR) and the peripheral benzodiazepine receptor (PBR) of rat brain was studied. Racemic mixture of 7-bromo-3-(2-methoxy)ethoxy-5-phenyl-1,2-dihydro-3H-1,4-benzodiazepin-2-one (13) was separated into enantiomers 14, 15 by chiral HPLC. Absolute configuration of R-enantiomer 15 was determined by the method of X-ray diffraction analysis. The affinity of S-enantiomer 14 for CBR (IC50 = 245 nM) is 20-fold higher than the affinity of R-enantiomer 15 (IC50 = 4930 nM). A high selectivity for CBR versus PBR (IC50 (PBR) > 10000 nM) was shown by all reported compounds. Compound 12 was revealed as a potent (IC50 = 9 nM) and selective CBR ligand among the synthesized 3-alkoxy-1,2-dihydro-3H-1,4-benzodiazepin-2-ones. (C) 2009 Elsevier Masson SAS. All rights reserved.
