Design, Synthesis, and Evaluation of Triazole Derivatives That Induce Nrf2 Dependent Gene Products and Inhibit the Keap1–Nrf2 Protein–Protein Interaction
摘要:
The transcription factor Nrf2 regulates the expression of a large network of cytoprotective and metabolic enzymes and proteins. Compounds that directly and reversibly inhibit the interaction between Nrf2 and its main negative regulator Keap1 are potential pharmacological agents for a range of disease types including neurodegenerative conditions and cancer. We describe the development of a series of 1,4-dipheny1-1,2,3-triazole compounds that inhibit the Nrf2-Keap1 protein protein interaction (PPI) in vitro and in live cells and up-regulate the expression of Nrf2-dependent gene products.
Triplex-forming ability of oligonucleotides containing 1-aryl-1,2,3-triazole nucleobases linked via a two atom-length spacer
摘要:
Phosphoramidites containing 2-propynyloxy or 1-butyn-4-yl as nucleobase precursors were synthesized and introduced into oligonucleotides using an automated DNA synthesizer. Copper-catalyzed alkyne-azide 1,3-dipolar cycloaddition of the oligonucleotides with various azides gave the corresponding triazolylated oligonucleotides, triplex-forming ability of these synthetic oligonucleotides with double-stranded DNA targets was evaluated by UV melting experiments. It was found that nucleobases containing 2-(1-m-carbonylaminophenyl-1,2,3-triazol-4-yl)ethyl units likely interacted with A of a TA base pair in a parallel triplex DNA. (C) 2013 Elsevier Ltd.

The present invention provides compounds according to Formula (I) as described herein, and their use for inhibiting the lysine gingipain protease (Kgp) from the bacterium Porphyromonas gingivalis. Also described are gingipain activity probe compounds and methods for assaying gingipain activity are also described, as well as methods for the treatment of disorders associated with P. gingivalis infection, including brain disorders such as Alzheimer's disease.
The synthesis and properties of multifunctional thioureas bearing a variety of functional groups at a position remote from the thiourea moiety are described. A 1,5-disubstitutedtriazole tether connected with a thiourea and another functional group was synthesized via ruthenium catalyzed Huisgen cycloaddition. We demonstrate the utility of the synthetic thioureas as asymmetric catalysts and probes
