  Trifluoroacetyl-HYNIC Peptides:  Synthesis and ^99mTc Radiolabeling

  摘要：

  Fmoc-lys(HYNIC-Boc)-OH, a precursor for solid-phase synthesis of Tc-99m-labeled peptides, was synthesized efficiently without HPLC purification. HPLC-ESMS showed that deprotection and decoupling of peptide from the resin with trifluoroacetic acid gave initially HYNIC-peptide, which was trifluoroacetylated upon prolonged incubation. The trifluoroacetyl-HYNIC group was hydrolyzed during Tc-99m labeling, rendering deprotection unnecessary. Trifluoroacetyl-HYNIC peptide was Tc-99m-labeled as efficiently, producing the same product, as HYNIC-peptide. These modifications enhance the versatility of HYNIC for Tc-99m peptide labeling.

  An efficient synthetic route to prepare two new HYNIC derivatives with a 2-nitroimidazole moiety designed for tumor hypoxia imaging is described. During the course of the synthesis, the optimization of N-alkylation reaction of 2- nitroimidazole with propargyl bromide is reported to favor the formation of the terminal alkyne versus allene. Thereafter, the two ligands were used with tricine/EDDA to complex 99mTc. However, decomposition of these ligands was observed and we suggest a reasonable explanation based on LC-MS analysis.

  Novel processes are disclosed for forming an array of polymers by functionalizing the surface of particles by methods that include covalently attaching a functionalized silicon compound. Substrates such as microparticles having functionalized silicon compounds attached thereto are produced by introducing at least one carboxyl group directly by silanating a carboxylated silane compound to the surface of a microparticle. In a further aspect of the invention, the silane compound is a dipodal carboxylated silane.

  Here we show a seven‐step chemical synthesis of a DNA‐encoded macrocycle library (DEML) on DNA. Inspired by polyketide and mixed peptide‐polyketide natural products, the library was designed to incorporate rich backbone diversity. Achieving this diversity, however, comes at the cost of the custom synthesis of bifunctional building block libraries. This study outlines the importance of careful retrosynthetic

  在这里，我们展示了在DNA上进行DNA编码的大环文库（DEML）的七步化学合成。受聚酮化合物和肽-聚酮化合物混合天然产物的启发，该文库旨在整合丰富的骨架多样性。但是，要实现这种多样性，就要以双功能构件块库的定制合成为代价。这项研究概述了在DNA编码文库中仔细进行逆向合成设计的重要性，同时揭示了需要新的DNA合成方法的领域。
