• Lipophilic chelates and their use in imaging
  申请人：Guerbet

  公开号：US08268810B2

  The invention relates to chelate compounds which can be used in MRI, the chelates being intended to be conveyed by lipophilic transporters, such as lipid nanoparticles or liposomes. The invention also relates to compounds comprising, in association, these chelates and these transporters, if appropriate connected via chemical bonding groups, and to their use in diagnostic imaging, it being possible for this association additionally to comprise biological targeting markers, denoted biovectors.

• Preparation of Carboxythiolactones and Their Active Derivatives
  作者：Bonnie J. Garbiras、Stephen Marburg

  DOI：10.1055/s-1999-3377

  日期：1999.2

  The design of peptidyl immunogens requires that a number of elements be covalently linked to enable the appropriate immune response to occur. Two of these elements are: (a) T-cell sequences which after processing, bind to major histocompatibility complex (MHC) molecules and T-cell receptors and (b) B-cell sequences which embody the constellation of atoms which will ultimately be recognized by the desired antibody. Our concept, designed to effectuate this, involved a single molecule which could conjugate three peptides, potentially in discrete steps, in one pot. Activated carboxythiolactones, hitherto unknown entities, provide such a system: two acyl sites susceptibile to nucleophilic attack at disparate rates and a liberated thiol susceptible to electrophilic alkylation. Such a set of thiolactones and their derivatives have been synthesized from inexpensive starting materials and their reactivities are under investigation. If successful, the system will not only obviate the difficult syntheses of longer linear peptides, but will also allow a rapid structural permutation of the various elements.

  肽基免疫原的设计需要将许多元件共价连接以能够发生适当的免疫反应。其中两个元素是：(a) T 细胞序列，经过加工后，与主要组织相容性复合体 (MHC) 分子和 T 细胞受体结合；(b) B 细胞序列，包含最终将被识别的原子群通过所需的抗体。我们的概念旨在实现这一目标，涉及单个分子，该分子可以在一锅中以不连续的步骤结合三个肽。迄今为止未知的活化的羧基硫内酯提供了这样的系统：两个对不同速率的亲核攻击敏感的酰基位点和一个对亲电烷基化敏感的释放的硫醇。这样一组硫内酯及其衍生物已经由廉价的起始原料合成，并且它们的反应性正在研究中。如果成功，该系统不仅将消除较长线性肽的困难合成，而且还将允许各种元素的快速结构排列。
