This disclosure is directed, at least in part, to AMPK activators useful for the treatment of conditions or disorders associated with AMPK. In some embodiments, the condition or disorder is associated with the gut-brain axis. In some embodiments, condition or disorder is associated with systemic infection and inflammation from having a leaky gut barrier. In some embodiments, the AMPK activators are gut-restricted compounds. In some embodiments, the AMPK activators are agonists or partial agonists.

requires multistep syntheses, and therefore latestage incorporation of these mimetics into peptides is not feasible. Here, we develop and employ metallaphotoredox catalysis using 4-halogenated phenylalanine to afford a variety of protected pTyr mimetics in one step. This methodology was shown to be tolerant of common protecting groups and applicable to the latestage pTyr mimetic modification of protected

The mechanism of dissociation of amino-substitutedgem-diphosphonic acids R2N(CH2)nCR'(PO3H2)2 with different lengths of the alkylidene chain and different substituents at the N atom was studied by vibrational (IR, Raman) and NMR (1H,14N,31P) spectroscopy using data of conformational analysis (molecular mechanical) data. The important role of intramolecular H-bonds and cyclic solvates for the stabilization
通过振动(IR,Raman)和NMR(1H,14N)研究了具有不同亚烷基链长度和不同N原子取代基的氨基取代的宝石-二膦酸R2N(CH2)nCR'(PO3H2)2的解离机理,31P) 光谱使用构象分析(分子力学)数据。证明了分子内 H 键和环状溶剂化物在稳定各种构象和互变异构形式的离子方面的重要作用。发现了允许将宝石-二膦酸酯基团视为单个酸性中心的光谱数据。
