  描述：

  benzyl N-(m - L-leucylaminomethylbenzyl)carbamate 在 palladium on activated charcoal 盐酸 、 氢气 、 1-羟基苯并三唑 、 1-羟基苯并三唑一水物 、 盐酸-N-乙基-Nˊ-(3-二甲氨基丙基)碳二亚胺 、 三乙胺 作用下， 以 1,4-二氧六环 、 乙醇 、 N,N-二甲基甲酰胺 为溶剂， 反应 37.0h， 生成 N-<(2R)-2-(8-isobutyl-6-phenyl-1,2,4-triazolo<4,3-a>pyrazin-3-yl)-3-pyridin-3-ylpropanoyl>-ACHPA-Leu-m-(aminomethyl)benzylamide

  1,2,4-Triazolo[4,3-a]pyrazine derivatives with human renin inhibitory activity. 1. Synthesis and biological properties of alkyl alcohol and statine derivatives

  摘要：

  A series of 1,2,4-triazolo[4,3-a]pyrazine derivatives with human renin inhibitory activity, which incorporate (1S,2S)-2-amino-1,3-dicyclohexyl-1-hydroxypropane, statine (Sta), and (3S,4S)-4-amino-5-cyclohexyl-3-hydroxy-pentanoic acid (ACHPA) transition-state mimetics, have been prepared. Structure-activity relationships for renin inhibitory activity in the series are consistent with the 2-[8-isobutyl-6-phenyl-1,2,4-triazolo[4,3-a]pyrazin-3-yl]-3-(3 pyridyl)propionic acid moiety 10b acting as a non-peptidic replacement for the P4-P2 (Pro-Phe-His) residues of the natural substrate angiotensinogen. Compounds 12m, 12o and 12q were potent inhibitors of partially purified human renin (IC50 values 1.7, 6.8, and 3.7 nM, respectively), and also effectively lowered blood pressure in anesthetized, sodium depleted marmosets following intravenous administration. On oral administration however, no blood pressure lowering activity could be detected, and absorption studies in bile duct cannulated rats indicate that this may be due primarily to poor oral absorption, rather than rapid biliary excretion. The reason for the observed poor oral activity is not clear, but it seems unlikely that poor aqueous solubility or metabolic instability to gut enzymes are rate-determining, and other factors such as high molecular weight may also be very important.

  Oligopeptides of formula (I): where R1R7 are various organic groups and n and m are 0 or 1, have renin-inhibitory activity and are particularly suitable for oral administration. They may be prepared by condensing their component amino acids or lower oligopeptides using conventional peptide synthesis reactions.

  式(I)的寡肽： 其中 R1R7 为各种有机基团，n 和 m 为 0 或 1，具有肾素抑制活性，特别适合口服。它们可以通过传统的肽合成反应缩合其氨基酸组分或低级寡肽来制备。
