  描述：

  N-(tert-butoxycarbonyl)norleucine amide of (2S,3R,4S)-2-amino-1-cyclohexyl-3,4-dihydroxy-6-methylheptane 在 N-甲基吗啉 、 1-羟基苯并三唑 、 盐酸-N-乙基-Nˊ-(3-二甲氨基丙基)碳二亚胺 、 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 19.5h， 生成 (2S)-2-[[(2R)-2-benzyl-4-(4-methylpiperazin-1-yl)-4-oxobutanoyl]amino]-N-[(2S,3R,4S)-1-cyclohexyl-3,4-dihydroxy-6-methylheptan-2-yl]hexanamide

  Studies directed toward the design of orally active renin inhibitors. 1. Some factors influencing the absorption of small peptides

  摘要：

  A systematic evaluation of structure-absorption relationships using a high throughput intraduodenal rat screening model has led to the delineation of a set of structural parameters that appear to govern bioavailability in a series of peptide-based renin inhibitors. Optimum structures, exemplified by 25 and 41, incorporated a single, solubilizing substituent at the C- or N-terminus combined with a lipophilic P2-site residue. Both inhibitors gave unprecedented plasma drug levels upon intraduodenal administration to monkeys, and the calculated bioavailability for 41 (14 +/- 4%) is the highest reported for any peptidic renin inhibitor.
