  Described herein are monomers capable of forming a biologically useful multimer when in contact with one, two, three or more other monomers in an aqueous media. In one aspect, such monomers may be capable of binding to another monomer in an aqueous media (e.g. in vivo) to form a multimer, (e.g. a dimer). Contemplated monomers may include a ligand moiety, a linker element, and a connector element that joins the ligand moiety and the linker element. In an aqueous media, such contemplated monomers may join together via each linker element and may thus be capable of modulating one or more biomolecules substantially simultaneously, e.g., modulate two or more binding domains on a protein or on different proteins.

  本发明描述了在水中介质中与一个、两个、三个或更多其他单体接触时能够形成具有生物学用途的多聚体的单体。在一方面，这样的单体可能能够在水介质中（例如，体内）与另一个单体结合形成多聚体（例如，二聚体）。考虑的单体可能包括一个配体部分、一个连接元素和一个连接器元素，连接器元素连接配体部分和连接元素。在水介质中，这样的考虑单体可能通过每个连接元素相互连接，因此可能能够实质上同时调节一个或多个生物分子，例如，调节蛋白质上的两个或多个结合域，或者调节不同蛋白质上的结合域。

  日期：2021.3.3

  Ribosomal protein synthesis is an important target in antibacterial drug discovery. Numerous natural products have served as starting points for the development of antibiotics. We report here the total synthesis of xenocoumacin 1, a natural product that binds to 16S ribosomal RNA at a highly conserved region, as well as analogues thereof. Preliminary structure–activity relationship studies were aimed

  核糖体蛋白合成是抗菌药物发现的重要目标。许多天然产物已成为抗生素开发的起点。我们在此报告异香豆素 1 的全合成，这是一种在高度保守的区域与 16S 核糖体 RNA 结合的天然产物及其类似物。初步的构效关系研究旨在了解和调节真核和原核核糖体之间的选择性。修饰主要在芳香区域被容忍。对革兰氏阴性菌的全细胞活性受到外排和渗透的限制，正如在大肠杆菌的转基因菌株中所证明的那样. 鉴定了对真核生物核糖体具有高选择性的类似物，但不可能获得对细菌蛋白质合成具有选择性的抑制剂。尽管真核和原核核糖体在结合区具有高度同源性，但实现高选择性（尽管不是理想的）是可能的。

  We report a catalytic asymmetric synthesis of piperidines through [4 + 2] cycloaddition of 1-azadienes and nitro-alkenes. The reaction uses earth abundant Zn as catalyst and is highly diastereo- and regioselective. A novel BOPA ligand (F-BOPA) confers high reactivity and enantioselectivity in the process. The presence of ortho substitution on the arenes adjacent to the bis(oxazolines) was found to

  我们报告了通过 1-氮杂二烯和硝基烯烃的 [4 + 2] 环加成反应催化不对称合成哌啶。该反应使用地球上丰富的锌作为催化剂，并且具有高度的非对映选择性和区域选择性。一种新型 BOPA 配体 (F-BOPA) 在该过程中具有高反应性和对映选择性。发现与双（恶唑啉）相邻的芳烃上存在邻位取代特别有影响，因为限制了 1-氮杂二烯与路易斯酸的不希望的配位，从而允许反应在较低温度下进行。使用一系列配体进行的一系列次级动力学同位素效应研究暗示了转化的逐步机制，包括亚胺与硝基烯烃的初始迈克尔型加成，然后是环化事件。
