Insights into Siglec‐7 Binding to Gangliosides: NMR Protein Assignment and the Impact of Ligand Flexibility

Advanced Science, EarlyView.
The molecular recognition of the sugar moiety of GD3 and Gb3 (globotriaosylceramide) derivatives by Siglec‐7 has been thoroughly studied offering insights for cancer diagnostics and therapies. A combination of structural biology techniques, nuclear magnetic resonance (NMR) spectroscopy, physicochemical analysis, and in silico methods suggested that ...

Discovery, Herbicidal Activity and Biosynthesis of a Novel Natural Tetramic Acid from Alternaria Species

Advanced Science, EarlyView.
The biosynthetic mechanism of novel natural tetramic acid S‐TeA in Alternaria alternata is elucidated. Threonine acts as a precursor for 2‐amino‐3‐methylhexanoic acid (AMHA) synthesis via eight key enzymes from the branched‐chain amino acid biosynthetic pathway in the mitochondrion, wherein three unique enzymes (IPMS, IPMDH, and ISMD) play critical ...

Exercise without Weight Loss Prevents Seasonal Decline in Vitamin D Metabolites: The VitaDEx Randomized Controlled Trial

Advanced Science, EarlyView.
In people with overweight or obesity, regular exercise even without weight loss or vitamin D supplementation completely prevents the usual winter decline in the vitamin D metabolite that maintains health at a cellular level, 1,25(OH)2D3, and ameliorates the decline in the vitamin D status marker 25(OH)D.

A General Strategy for C(sp3)─H Bond Etherification via Quinoline Derivative‐Mediated Electrolysis

Advanced Science, EarlyView.
A quinoline‐based mediator is introduced for the electrochemical etherification of C(sp3)─H bonds, enabling the process with minimal dependence on substrate electronic properties. The reaction demonstrates compatibility with various C─H bonds, including tertiary benzylic C─H bonds and unactivated C(sp3)─H bonds.
