  (2S)-2-Amino-N-[(5S)-4,5-dihydro-3-methyl-4-oxo-3H-2,3-benzodiazepin-5-yl]propanamide 、 S-(+)-3,5-二氟扁桃酸 在 benzotriazol-1-yloxyl-tris-(pyrrolidino)-phosphonium hexafluorophosphate 、 三乙胺 作用下， 以 二氯甲烷 为溶剂， 反应 6.0h， 生成 (ALPHAS)-N-[(1S)-2-[[(5S)-4,5-二氢-3-甲基-4-氧代-3H-2,3-苯并二氮杂卓-5-基]氨基]-1-甲基-2-氧代乙基]-3,5-二氟-ALPHA-羟基苯乙酰胺

  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.
