• Synthesis and Structure−Activity Relationships of 2-Pyridones:  A Novel Series of Potent DNA Gyrase Inhibitors as Antibacterial Agents

  DOI：10.1021/jm960207w

  日期：1996.1.1

  Two novel series of 2-pyridones were synthesized by transposition of the nitrogen of 4-quinolones to the bridgehead position. This subtle interchange of the nitrogen atom with a carbon atom yielded two novel heterocyclic nuclei, pyrido[1,2-alpha]pyrimidine and quinolizine, which had not previously been evaluated as antibacterial agents and were found to be potent inhibitors of DNA gyrase. Quinolizines

  通过将4-喹诺酮类的氮转位至桥头位置，合成了两个新颖的2-吡啶酮系列。氮原子与碳原子的这种微妙的交换产生了两个新的杂环核，吡啶并[1,2-α]嘧啶和喹啉嗪，它们先前未被评估为抗菌剂，并且被发现是DNA促旋酶的有效抑制剂。（S）-45a（ABT-719）等在9位甲基的喹唑啉酮具有出色的广谱抗菌活性。最值得注意的是，它们对耐药菌具有活性，例如耐甲氧西林的金黄色葡萄球菌，耐万古霉素的肠球菌菌株和耐环丙沙星的生物。此外，2-吡啶酮还具有良好的理化和药代动力学特性。这些2-吡啶酮是通过10-17个线性转化从商购可得的起始原料合成的。通过X射线晶体学分析确定由该序列产生的加合物（S）-45a（ABT-719）的结构。

• N-benzhydryl-glycolamide esters (OBg esters) as carboxyl protecting groups in pept1de synthesis
  作者：Muriel Amblard、Marc Rodriguez、Jean Martinez

  DOI：10.1016/s0040-4020(01)86014-2

  日期：1988.1

  N-Benzhydryl-glycolamide esters (OBg esters) of various N-protected amino acids have been synthesized. In order to demonstrate their usefulness in peptide chemistry, the syntheses of For-Met-Leu-Phe-OH (chemiotactic peptide) and Pro-Leu-Gly-NH2 (MIF) have been carried out. OBg esters are compatible with commonly used protecting groups and are cleanly and selectively removed in mild alkaline conditions

  已经合成了各种N-保护的氨基酸的N-苯甲酰基-乙醇酰胺酯（OBg酯）。为了证明它们在肽化学中的有用性，已经进行了For-Met-Leu-Phe-OH（趋化肽）和Pro-Leu-Gly-NH 2（MIF）的合成。OBg酯与常用的保护基团相容，并且除含有β-苄基天冬氨酰的序列外，在温和的碱性条件下可以干净而有选择地除去，而没有任何副反应。
• Small peptides as modular catalysts for the direct asymmetric aldol reaction: ancient peptides with aldolase enzyme activity
  作者：Weibiao Zou、Ismail Ibrahem、Pawel Dziedzic、Henrik Sundén、Armando Córdova

  DOI：10.1039/b509920j

  日期：——

  Simple peptides and their analogues having a primary amino group as the catalytic residue mediate the direct asymmetric intermolecular aldol reaction with high stereoselectivity and furnish the corresponding aldol products with up to 99% ee; this intrinsic ability of highly modular peptides may explain the initial molecular evolution of aldolase enzymes.

  具有作为催化残基的主氨基的简单肽及其类似物，能以高立体选择性促进直接的不对称分子间醛醇反应，并生成最高达99% 对映体过量值的相应醛醇产物；这种高度模块化肽的内在能力可能解释了醛缩酶酶的初始分子进化过程。
