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.

MIO‐independent reaction pathway, which proceeds in a non‐stereoselective manner and results in the generation of both L‐ and D‐phenylalanine derivatives, is described. The mechanism of the MIO‐independent pathway is explored through isotopic‐labeling studies and mutagenesis of key active‐site residues. The results obtained are consistent with amino acid deamination occurring by a stepwise E1cBelimination mechanism
苯丙氨酸解氨酶 (PAL) 属于 4-亚甲基咪唑-5-酮 (MIO) 辅因子依赖性酶家族,其负责在真核生物和原核生物中将L-苯丙氨酸转化为反式肉桂酸。在高氨浓度条件下,这种脱氨反应是可逆的,因此人们对开发 PAL 作为非天然氨基酸的对映选择性合成的生物催化剂有相当大的兴趣。在此发现了一种以前未观察到的竞争性 MIO 非依赖性反应途径,该反应途径以非立体选择性方式进行并导致L-和D的产生描述了-苯丙氨酸衍生物。通过同位素标记研究和关键活性位点残基的诱变探索了 MIO 非依赖性途径的机制。获得的结果与通过逐步 E 1 cB 消除机制发生的氨基酸脱氨基作用一致。

a supramolecular emission‐switch‐on chemosensor in water. Complex formation of the heterocycles with a platinum(II) precursor proceeds readily at ambient conditions, allowing for facile analyte screening. Fifty‐two structurally diverse compounds were tested, out of which 23 pyridines, imidazoles, and triazoles formed strongly emissive complex aggregates. Importantly, they all can be clearly distinguished
开发了一种用于氮杂杂环药物和毒素的反应性磷光探针,可提供水中的超分子发射开关化学传感器。杂环与铂(II)前体的复杂形成在环境条件下容易进行,从而可以轻松进行分析物筛选。测试了52种结构多样的化合物,其中23种吡啶,咪唑和三唑形成了强发射复合物聚集体。重要的是,可以通过主成分分析将它们清晰地区分开,但通常还可以通过简单的目视检查,例如通过它们的发射颜色差异(从蓝色到红色的大变化)。而且,动力学反应曲线和时间分辨的发射特征可以为区分分析物提供有价值的信息。Pt II 由于它们具有良好的光物理特性和在诸如血液等生物介质中的化学稳定性,因此它们可以用作药物和生物分子的发射标记。
