制备方法与用途

生物活性

β-环状丙氨酸（Beta-cyano-l-alanine）是一种广泛存在于高等植物中的腈，由氰基丙氨酸合成酶从氰化物和半胱氨酸作为底物酶促产生。研究显示，β-环状丙氨酸可以消除乙醇对脑缺血/再灌注（I/R）损伤的保护作用。

体内研究

β-环状丙氨酸 (腹腔注射；50 mg/kg) 可以消除乙醇对大脑缺血/再灌注 (I/R) 损伤的保护效果。具体实验结果如下：

• 动物模型：成年（出生后60天）雄性C57BL/6J小鼠（体重25-30 g），通过胃管喂养乙醇。
• 剂量：50 mg/kg
• 给药途径：腹腔注射
• 结果：消除乙醇对大脑I/R损伤的保护作用。

  重新利用非血红素铁羟化酶以通过叠氮基团协助实现催化腈安装

  摘要：

  三种单核非血红素铁和 2-酮戊二酸依赖性酶，l-Ile 4-羟化酶、l-Leu 5-羟化酶和多氧辛二羟化酶，先前已报道可催化 l-异亮氨酸、l-亮氨酸和 l-α-氨基的羟基化-δ-氨基甲酰基羟基戊酸（ACV）。在这项研究中，我们表明这些酶可以容纳亮氨酸异构体并催化区域特异性羟基化。在这些结果的基础上，作为概念验证，我们证明了反应的结果可以通过在基板内安装辅助组来重定向。具体来说，当引入叠氮基时，这些酶可以催化非天然腈基的安装，而不是经典的羟基化。该反应很可能通过 Fe(IV)-氧类物质激活 CH 键进行，然后形成叠氮导向的 C≡N 键。

• New Chiral Derivatizing Agents: Convenient Determination of Absolute Configurations of Free Amino Acids by ¹H NMR
  作者：Michio Kurosu、Kai Li

  DOI：10.1021/ol8028719

  日期：2009.2.19

  The chiral carbonate reagents 5 allow for the direct and unambiguous determination of the absolute configurations of a wide range of free amino acids using 1H NMR. By using a ∼3:1 mixture of (S)-5 and (R)-5, absolute configurations of the corresponding carbamates are determined by only analyzing the nitrogen protons.
