  摘要：

  研究了由α-氨基腈制备O-甲基亚氨酸盐，然后与伯胺共环化以生成4-取代的5-氨基咪唑。已经发现，弱酸性对甲苯磺酸吡啶鎓吡啶鎓盐有效地催化了反应顺序的每个阶段：（a）O-甲基亚氨酸酯的形成，（b）它们与多种伯胺的共环化，以及（c）某些所得杂环的衍生化。发达的反应条件可以耐受多种α-氨基腈和伯胺共反应物。因此，可以容易地以高收率制备各种各样的取代的杂环化合物。必需的α-氨基腈可以从氨基酸合成，也可以通过甘氨酸阴离子当量的相转移烷基化来合成。

  Design, Synthesis, Molecular Modeling Studies, and Calpain Inhibitory Activity of Novel α-Ketoamides Incorporating Polar Residues at the P₁‘-Position

  摘要：

  A series of novel alpha-ketoamides incorporating stereoisomeric residues with different electronic properties at the P-1'-position were synthesized to study the electronic requirements for inhibitor binding to the S-1'-subsite of calpain I. The results of the study suggested the presence of an acidic amino acid residue at the S-1'-subsite of calpain I. For example, ester la (CbZ-L-Leu-L-Phe-CO-D-Phe-OMe) was over 450-fold more potent than its carboxylic acid derivative 2a (Cbz-L-Leu-L-Phe-CO-D-Phe-OH). Additionally, amidino derivative 3a (CbZ-L-Leu-L-Phe-CONH-D-CH[C(NH)NH2]Bn) was about 6000-fold more potent than 2a. Furthermore, 4a (Cbz-L-Leu-L-Phe-CONHCH2Bn) was 12-fold less potent than its aza analogue 4b (CbZ-L-Leu-L-Phe-CONHNHBn). The results are consistent with the presence of an acidic amino acid residue at the S-1'-subsite of calpain I. The acidic amino acid residue was found to be Glu261 via molecular modeling studies.

• Primary amides as selective inhibitors of cathepsin K
  作者：Serge Léger、Christopher I. Bayly、W. Cameron Black、Sylvie Desmarais、Jean-Pierre Falgueyret、Frédéric Massé、M. David Percival、Jean-François Truchon

  日期：2007.8

  The nitrile warhead used in a series of cathepsin K inhibitors can be replaced by a less electrophilic primary amide. The accompanying loss of potency can be partially recovered by introducing a substituent alpha to the amide. The potency gain resulting from this addition is not achieved with the nitrile derivatives due to a different geometry of the cysteine adduct in the enzyme active site. This

  一系列组织蛋白酶K抑制剂中使用的腈弹头可以用亲电性较低的伯酰胺代替。通过将取代基α引入酰胺中，可以部分地弥补伴随的效力损失。由于腈活性衍生物在酶活性位点中半胱氨酸加合物的几何形状不同，因此用腈衍生物不能实现这种添加所带来的效价提高。这项研究导致鉴定了作为抑制底物的伯酰胺2g，对组织蛋白酶K的IC（50）为10 nM，与其他组织蛋白酶相比具有出色的选择性。
