  Novel backbone-cyclized peptidomimetics of the general formula cyclo[-P1-P2-P3-P4-P5-P6-P7-P8-T1-T2-] (I) wherein the single elements T or P are α-amino acid residues connected in either direction which, depending on their positions in the chain, are as defined in the description and the claims, and salts thereof, have the property to modulate the GLP-1 receptor. They can be used as medicaments to treat, prevent, or delay the onset of diseases, disorders or conditions in which modulation of the human GLP-1 receptor is beneficial, such as type 2 diabetes. These backbone-cyclized peptidomimetics can be manufactured by a process which is based on a mixed solid- and solution phase synthetic strategy.

  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。
