by using a simple 2,2′-biphenol-derived phosphoric acid catalyst (2.5–10 mol%). This reaction was also successfully conducted at the gram scale. To demonstrate the synthetic utility of this catalytic system, pharmaceutically useful substrates and acid-sensitivesubstrates were examined using these acid–base cooperative phosphoric acid catalysts, which exhibit relatively weak Brønsted acidity.
通过使用简单的 2,2'-联苯酚衍生的磷酸催化剂(2.5–10 mol%),在 100 °C 下促进了羧酸和伯醇或仲醇的等摩尔混合物在甲苯中的脱水酯化反应,无需除去水。 )。该反应也在克级上成功进行。为了证明该催化系统的合成效用,使用这些酸碱协同磷酸催化剂对药学上有用的底物和酸敏感底物进行了检查,这些催化剂表现出相对较弱的布朗斯台德酸性。

Disclosed herein are modified C-terminal fragments of FGF21 optimized for binding to Klotho β or antagonizing FGF21 activity. FGF21 peptides modified to comprise modifications to the C-terminal amino acid sequence are disclosed that have enhanced activity at the FGF21 receptor. Additionally, conjugates formed between the optimized FGF21 peptide fragments and insulin like peptides or nuclear hormone receptor ligands are provided.
本文公开了经过修饰的 FGF21 C 端片段,这些片段经过优化,可与 Klotho β 结合或拮抗 FGF21 的活性。已公开的 FGF21 多肽包括对 C 端氨基酸序列的修饰,在 FGF21 受体上具有更强的活性。此外,还提供了优化的 FGF21 肽片段与胰岛素样肽或核激素受体配体之间形成的共轭物。
