  1,3-恶唑烷酮-5-酮和1,3-恶唑烷酮-6-酮由二十种常见的α-氨基酸合成N-甲基β-氨基酸的有效方法

  摘要：

  应用N-甲基β-氨基酸通常是潜在合成具有生物活性的修饰的肽和其他寡聚体的应用。先前的工作强调了1，3-恶唑烷-5-酮的还原裂解以合成N-甲基α-氨基酸。从α-氨基酸开始，使用两种方法来制备相应的N-甲基β-氨基酸。首先，α -氨基酸转化为Ñ甲基α -氨基酸由所谓的“-1,3-恶唑-5-酮的策略”，将它们再由同系阿恩特-艾斯特方法，得到Ñ-protected Ñ -甲基β -氨基酸选自20种常见衍生α -氨基酸。这些化合物的制备产率为23–57％（相对于N-甲基α-氨基酸）。在第二种方法中，可以通过Arndt–Eistert方法将12个N保护的α-氨基酸直接同源，然后将所得的β-氨基酸以30–45％的产率转化为1,3-恶二嗪-6-酮。 。最后，还原裂解以41–63％的收率提供了所需的N-甲基β-氨基酸。

• Application of acyl cyanophosphorane methodology to the synthesis of protease inhibitors: poststatin, eurystatin, phebestin, probestin and bestatin
  作者：Harry H Wasserman、Anders K Petersen、Mingde Xia

  DOI：10.1016/s0040-4020(03)00860-3

  日期：2003.8

  Full details are given for the syntheses of the protease inhibitors, poststatin and eurystatin by the acyl cyanophosphorane coupling procedure used for the formation of α-keto amides. We have also extended this methodology to the syntheses of the related α-hydroxy amide natural products, phebestin, probestin and bestatin. The key step in the latter synthetic sequences involved diastereomeric selectivity

  β-amyloid peptide (βAF) production in cell culture and in vivo is inhibited by administering aspartyl protease inhibitors, particularly inhibitors of proteases of cathepsin D. Useful aspartyl protease inhibitors can be selected in a two-step assay, where test compounds are first screened for aspartyl protease inhibition activity in vitro in noncellular assays. Those test compounds which are found to display protease inhibition activity are then tested in cellular assays for βAP production inhibition. Those test compounds which are capable of inhibiting intracellular β-amyloid production may be incorporated in pharmaceutical compositions.

  β-淀粉样蛋白（βAF）在细胞培养和体内的产生受到阻断，通过给予天冬氨酸蛋白酶抑制剂，特别是半胱氨酸蛋白酶D的抑制剂。有用的天冬氨酸蛋白酶抑制剂可以在两步法测定中选择，其中首先在非细胞试验中筛选测试化合物是否具有体外天冬氨酸蛋白酶抑制活性。那些被发现具有蛋白酶抑制活性的测试化合物随后在细胞试验中进行βAP产生抑制的测试。那些能够抑制细胞内β-淀粉样蛋白产生的测试化合物可以被纳入药物组合物中。

  The main protease of SARS‐CoV‐2 (Mpro), the causative agent of COVID‐19, constitutes a significant drug target. A new fluorogenic substrate was kinetically compared to an internally quenched fluorescent peptide and shown to be ideally suitable for high throughput screening with recombinantly expressed Mpro. Two classes of protease inhibitors, azanitriles and pyridyl esters, were identified, optimized

  SARS-CoV-2 (M pro ) 的主要蛋白酶是 COVID-19 的病原体，是一个重要的药物靶点。一种新的荧光底物与内部淬灭的荧光肽进行了动力学比较，结果表明它非常适合用重组表达的 M pro进行高通量筛选。两类蛋白酶抑制剂，氮腈和吡啶酯，经过鉴定、优化并进行了深入的生化表征。配备独特氮腈弹头的定制肽同时抑制 M pro和组织蛋白酶 L（一种与病毒细胞进入相关的蛋白酶）。通过位置扫描分析吡啶基吲哚酯。事实证明，我们针对 M pro抑制剂的重点方法优于虚拟筛选。使用两种不可逆抑制剂，氮腈8 (k inac /K=37 500 m -1 s -1 , K=24.0 nm ) 和吡啶酯17 (k inac /K=29 100 m -1 s -1 , K=10.0 nm ），已经发现了有希望进一步开发的候选药物。
