  澄清格拉纳达烯的结构：相关类似物[2]-格拉纳达烯的全合成及其绝对立体化学的确认

  摘要：

  无乳链球菌是第一世界新生儿感染的重要因素。一种最广泛的鉴定方法是基于对患者样品中一种名为[12]-格拉那丹（1）的特征性红色色素的检测。在本文中，我们提出了一种模块化和灵活的方法来合成该鸟氨酸鼠李糖多烯1的简单类似物，并阐明其结构的最重要特征：C-27处的绝对构型，异头中心的立体化学和连接氨基酸鸟氨酸对其余结构的影响。

• Optimization of dipeptidic inhibitors of cathepsin L for improved Toxoplasma gondii selectivity and CNS permeability

  cathepsin L. Starting from a known inhibitor of human cathepsin L, and guided by structure-based design, we were able to modulate the selectivity for Toxoplasma vs human CPL by nearly 50-fold while modifying physiochemical properties to be more favorable for metabolic stability and CNS penetrance. The overall potency of our inhibitors towards TgCPL was improved from 2 μM to as low as 110 nM and we successfully

  神经质原生动物弓形虫是美国食源性疾病导致的第二大死亡原因，并已被美国疾病控制与预防中心指定为五种被忽略的寄生虫感染之一。当前，对于中枢神经系统（CNS）中的慢性休眠期弓形虫感染尚无治疗选择。弓形虫组织蛋白酶L（TgCPL）最近被认为是治疗慢性弓形虫病的新型可行靶标。在这项研究中，我们报告了SAR研究的第一个目标，该研究旨在开发对人组织蛋白酶L具有选择性的强效TgCPL抑制剂。从已知的人组织蛋白酶L抑制剂开始，并在基于结构的设计指导下，我们能够进行调节弓形虫对人CPL的选择性提高了近50倍，同时修改了其理化特性，使其更有利于代谢稳定性和中枢神经系统渗透性。我们的抑制剂对TgCPL的总体效力从2μM降低至低至110 nM，我们成功地证明了优化的类似物18b能够穿越血脑屏障（0.5脑/血浆）。这项工作是开发CNS渗透探针以验证TgCPL作为治疗慢性弓形虫病可行目标的重要第一步。

  amino acids. Resulting SAR analysis revealed the allyltyrosine residue was a key feature for IN inhibitory activity whilst incorporation of a lysine residue and extended hydrophilic chains bearing a terminal methyl ester was advantageous. Addition of hydrophobic aromatic moieties to the N-terminal of the scaffold afforded compounds with improved inhibitory activity. Consolidation of these functionalities

  从合成抗菌肽的文库筛选中，鉴定出一种基于O-烯丙基酪氨酸的三肽具有抗HIV-1整合酶（IN）的抑制活性，并具有IC 50在3'-处理和链转移微量滴定板分析的组合中的最大值为17.5μM。该三肽用28种肽进行了结构-活性关系（SAR）研究，其中包含了一系列天然和非天然氨基酸。SAR分析表明，烯丙基酪氨酸残基是IN抑制活性的关键特征，而掺入赖氨酸残基和带有末端甲酯的延长亲水链则是有利的。将疏水性芳族部分添加至支架的N-末端，提供了具有改善的抑制活性的化合物。这些功能的整合导致三肽96的发展，该三肽96特异性地抑制了IN链转移反应，其IC 50值为2.5μM。

  initiation. Herein we report the use of a chemoenzymatic strategy to complete the first total synthesis of GE81112 B1. By pairing iron and α-ketoglutarate dependent hydroxylases found in GE81112 biosynthesis with traditional synthetic methodology, we were able to access the natural product in 11 steps (longest linear sequence). Following this strategy, 10 GE81112 B1 analogues were synthesized, allowing for identification
