NAD + ‒circadian rhythm coupling in dementia

Shiqi Zhang, Jiyeon Lee, Jun‐Ping Pan, Rune Enger et autres

Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD + ) interacts with the circadian system through multiple molecular …

Synthesis of Chiral Sulfilimines via Copper-Catalyzed Enantiospecific Arylation of Sulfenamides

Min Han, Shiqi Zhang, Xin Yu Cui, Zhuo Tang et autres

Chiral sulfilimines represent a type of chiral S(IV) compound that is versatile as pharmacophores and chiral building blocks for chiral S(VI) compounds. Herein, we report an efficient method of preparing chiral sulfilimines (up to 90% yield and up to 96% enantiomeric excess) …

Mapping pesticide-induced metabolic alterations in human gut bacteria

Li Chen, Hongbin Yan, Shanshan Di, Chao Guo et autres

Pesticides can modulate gut microbiota composition, but their specific effects on it remain largely elusive. In our study, we show that pesticides inhibit or promote the growth of various gut microbial species and can be accumulated to prolong their presence in the …
