  描述：

  tert-butyl 5-amino-3-methyl-4-oxo-1,5-dihydro-2,3-benzodiazepine-2-carboxylate 在 1-羟基苯并三唑 、 1-(3-二甲基氨基丙基)-3-乙基碳二亚胺 、 三乙胺 、 三氟乙酸 作用下， 以 二氯甲烷 、 N,N-二甲基甲酰胺 为溶剂， 反应 4.0h， 生成 (2S)-2-[[2-(3,5-difluorophenyl)acetyl]amino]-N-(3-methyl-4-oxo-2,5-dihydro-1H-2,3-benzodiazepin-5-yl)propanamide

  Discovery of (S)-2-((S)-2-(3,5-difluorophenyl)-2-hydroxyacetamido)-N-((S,Z)-3-methyl-4-oxo-4,5-dihydro-3H-benzo[d][1,2]diazepin-5-yl)propanamide (BMS-433796): A γ-secretase inhibitor with Aβ lowering activity in a transgenic mouse model of Alzheimer’s disease

  摘要：

  We report on the design of benzodiazepin ones as peptidomimetics at the carboxy terminus of hydroxyamides. structure-activity relationships of diazepinones were investigated and orally active gamma-secretase inhibitors were synthesized. Active metabolites contributing to AP reduction were identified by analysis of plasma samples from Tg2576 mice. In particular, (S)-2-((S)-2-(3,5-difluorophenyl)-2-hydroxyacetamido)-N-((S,Z)-3-methyl-4-oxo-4,5-dihydro-3H-benzo[d][1,2]diazepin-5-yl)propanamide (BMS-433796) was identified with an acceptable pharmacodynamic and pharmacokinetic profile. Chronic dosing of BMS-433796 in Tg2576 mice suggested a narrow therapeutic window and Notch-mediated toxicity at higher doses. (C) 2007 Elsevier Ltd. All rights reserved.
