Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

European Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Nutraceutical Benefits of Anchomanes difformis Rhizome and Its Effects on Blood Glucose and Hepatorenal Function in Normoglycemic Rats

Food Chemistry International, EarlyView.
Scientific analysis of Anchomanes difformis roots confirms significant nutraceutical potential, containing high levels of carbohydrates, proteins, and essential minerals. Phytochemical screening revealed antioxidants such as phenols and flavonoids, and although the extracts effectively lowered plasma glucose, safety testing showed dose‐dependent risks.

Synthesis and Optical Properties of Diboron Complexes of 1,4-Anthraquinone Derivatives. [PDF]

Chemistry
1,4‐Diboron complexes exhibit near‐infrared fluorescence, in contrast to non‐emissive 1,5‐diboron analogues. Fluorescence quantum yields decrease with increasing electron‐donating substituents, attributed to enhanced nonradiative decay via intramolecular PeT.

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...
