  1,3,5-Triazine-Based Mass Spectral Tagging of One-Bead One-Compound Libraries

  摘要：

  A triazine-based mass encoding strategy that accommodates cleavable linker, isotopic labeling, and diversity receptor moieties is reported. The resulting triazine-based tags, which are coupled to bifunctionalized TentaGel resin in a one-pot transformation, enable the construction of a 1-oxa-2,8-diazaspiro[4.5]dec-2-ene-7-carboxamide library and facilitate decoding by equalizing the ionization potential of the liberated tags in single bead MALDI-TOF experiments as well as balancing the reactivity of the starting tags in the resin coupling step.

  Anthranilic acid based CCK1 receptor antagonists: Blocking the receptor with the same ‘words’ of the endogenous ligand

  摘要：

  The anthranilic acid diamides represent the more recent class of nonpeptide CCK1 receptor antagonists. This class is characterized by the presence of anthranilic acid, used as a molecular scaffold, and two pharmacophores selected from the C-terminal tetrapeptide of CCK. The lead compound coded VL-0395, endowed with sub-micromolar affinity towards CCK1 receptors, was characterized by the presence of Phe and 2-indole moiety at the C- and N-termini of anthranilic acid, respectively. Herein we describe the first step of the anthranilic acid C- terminal optimization using, instead of Phe, aminoacids belonging to the primary structure of CCK-8 and other not coded residues. Thus we demonstrate that the CCK1 receptor affinity depends on the nature of the aminoacidic side chain as well as that the free carboxy group of the alpha-aminoacids is crucial for the binding. The R enantiomers of the most active compounds represent the eutomers of this class of antagonists confirming thus the stereo preference of the receptor. Moreover this SAR study demonstrates that the receptor binding pocket, that host the aminoacidic side chain, results much more tolerant respect to that accommodating the indole ring. As a result, an appropriate variation of the aminoacidic side chain could provide a better CCK1 receptor affinity diorthosis. (C) 2009 Elsevier Ltd. All rights reserved.

  A microwave‐assisted highly efficient intermolecular C−H functionalization sequence has been developed to access substituted isoquinolones using α‐amino acid esters as a directing group. This methodology enables a wide range of N‐benzoyl α‐amino ester derivatives to react via a Ru‐catalysed C−H bond activation sequence, to form isoquinolones with moderate to excellent yields. As an additional advantage

  微波辅助高效分子间C-H官能化序列已经发展到使用访问取代的异喹诺酮化合物α -氨基乙酸酯定向基团。这种方法可以使大量的N-苯甲酰基α-氨基酯衍生物通过Ru催化的CH键激活序列反应，以中等到极好的收率形成异喹诺酮类化合物。作为一个额外的优势，我们的策略被证明具有广泛的适用性，并且还使烯烃的反应能够提供链烯基化的苯甲酰胺的途径。该方法还扩展到异喹啉生物碱衍生物的合成，即。氧鸟嘌呤和二肽。所开发的方案既简单又便宜，避免了繁琐的后处理程序，并在MW辐射下有效地工作。
