  This invention to provide a process for producing an optically active threo-phenylnorstatin derivative which does not require a toxic cyanating agent or a costly reagent, or a complicated procedure, and can be practiced on a commercial scale. This invention is directed to a process for producing a &bgr;-amino-&agr;-hydroxy acid derivative which comprises treating either a &ggr;-amino-&bgr;-keto sulfoxide derivative with a halogenating agent to produce a &ggr;-amino-&agr;-halo-&bgr;-keto sulfoxide derivative, treating the same with an acid and an alcohol to produce a &bgr;-amino-&agr;-keto ester derivative or &bgr;-amino-&agr;-keto acid derivative, and followed by reducing.

  这项发明提供了一种生产光学活性的threo-phenylnorstatin衍生物的方法，该方法不需要有毒的氰化剂或昂贵的试剂，也不需要复杂的程序，可以在商业规模上实施。这项发明涉及一种生产β-氨基-α-羟基酸衍生物的方法，包括用卤化剂处理γ-氨基-β-酮亚砜衍生物以产生γ-氨基-α-卤-β-酮亚砜衍生物，再用酸和醇处理相同物质以产生β-氨基-α-酮酯衍生物或β-氨基-α-酮酸衍生物，最后进行还原。

  公开（公告）日：2002-04-02

  The present invention relates to a process for reacting &agr;-aminoaldehyde derivatives having a sterically bulky amino group which are commercially available with a metal cyanide in the presence of an acid chloride, an acid anhydride or the like to synthesize 3-amino-2-hydroxybutyronitrile derivatives in high yields and high erythro selectivity. When optically active &agr;-aminoaldehyde derivatives are used, racemization hardly occurs during the reaction, and the desired products are obtained in high optical purity.

  本发明涉及一种方法，用于将具有立体位阻氨基团的α-氨基醛衍生物与金属氰化物在酸氯化物、酸酐或类似物的存在下反应，以高产率和高红细胞选择性合成3-氨基-2-羟基丁腈衍生物。当使用光学活性的α-氨基醛衍生物时，在反应过程中几乎不会发生外消旋，所以可以获得高光学纯度的期望产物。
• Synthesis and biological evaluation of chromone carboxamides as calpain inhibitors

  Excessive calpain activations contribute to serious cellular damage and have been found in many pathological conditions. Novel chromone carboxamides derived from ketoamides were prepared and evaluated for mu-calpain inhibition. Among synthesized, compound 2i was the most potent calpain inhibitor with an IC50 value of 0.24 +/- 0.11 mu M comparable to the activity of peptide aldehyde calpain inhibitor MDL 28,170. Furthermore, compound 2i showed higher selectivity for mu-calpain over two related cysteine proteases cathepsin B and cathepsin L, suggesting the chromone ring as a good scaffold for selective mu-calpain inhibitors.
