SKN-1, the ortholog of mammalian Nrf2 proteins, is a transcription factor that plays an important role in oxidative stress resistance and longevity. Similar to other defense systems, the Nrf2-mediated stress response is compromised in aging and neurodegenerative diseases. Our previous studies demonstrated that tetramethylpyrazine nitrone (TBN), a derivative of tetramethylpyrazine armed with a potent free radical-scavenging nitrone moiety, exerted multifunctional neuroprotection in neurol. and other diseases. However, the ability of TBN to extend a healthy lifespan and its underlying mechanisms of action are not yet clear. C. elegans have become a popular animal model in aging research. Herein, we demonstrate that TBN can extend the lifespan, promote age-associated health indicators, and restore mitochondrial function in C. elegans. TBN also significantly reduced ROS levels and superoxide accumulation in C. elegans. We show that TBN-mediated lifespan extension is SKN-1dependent. The present study provides valuable insights into the mechanisms by which TBN inhibits aging via the Nrf2/SKN-1 pathway in C. elegans. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7Formula: C11H15N2O8P).
((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7) belongs to amides. Amides can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group −NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)− joined to an amine group. Amides are stable compounds. The lower-melting members (such as acetamide) can be readily purified by fractional distillation. Most amides are solids which have low solubilities in water.Formula: C11H15N2O8P
