Article Abstract
Nanoscale molecular materials have emerged as a new class of compounds at the nanometer scale with well-defined chemical structures, remarkable uniformity and high reproducibility. Among these materials, zirconium-based metal-organic cages (MOCs) have attracted significant attention due to their exceptional stability and applications in catalysis, recognition and separation and so on. However, their poor water solubility impedes their biomedical applications. In this study, decorating the ligand with Ru(II) complexes can not only improve the water solubility but also endow bright red fluorescence with large Stokes shift (180 nm). Notably, butyl-modification of the cyclopentadiene rings can significantly enhance the cell uptake (100 folds) of nanocages via actin- and dynamin-mediated endocytosis. The unique advantages and easy modifiability of these nanocages make them highly promising candidates for diverse biological applications.

This study investigates the synthesis of aromatic nitriles using an evolved variant of OxdF1 (L318F/F306Y), an aldoxime dehydratase from Pseudomonas putida F1, engineered for improved catalytic efficiency toward benzaldehyde oxime. The double OxdF1 (L318F/F306Y) mutant effectively catalyzes the conversion of various benzaldoxime derivatives to the corresponding nitriles. Due to the enzyme's inherent instability, immobilized whole-cell systems are employed in a flow reactor to improve its stability and broaden its applicability, with the biotransformation of benzaldehyde oxime and 2,6-difluorobenzaldehyde oxime serving as case studies.

Developing artificial hosts with temperature-driven conformational switching behaviors facilitates our understanding of the temperature-dependent allostery and adaptation mechanisms in natural recognition systems. Herein, we report the design and synthesis of three pairs of water-soluble, enantiomeric binaphthalene-based tetraimidazolium macrocycles (SS/RR-1•4Cl- - SS/RR-3•4Cl-) as artificial hosts for exploring sequence-selective recognition of dinucleotides in aqueous media. Owing to the reversible rotational conformation of axially chiral binaphthyl units, SS-1•4Cl- demonstrates the conformational switching, converting from cis-conformation (SS-1) to trans-conformation (SS-1) by increasing temperature, thereby causing the recognition cavity to transition from a closed to an open state.

Hypertension represents a major risk factor for cardiovascular diseases. As a diet high in sodium chloride is associated with hypertension, so-called "blood pressure salts" are attracting increasing scientific interest. These are characterized by a partial replacement of sodium chloride by other salts, mainly potassium and magnesium compounds.

This review highlights the integration of drug repurposing and nanotechnology-driven delivery strategies as innovative approaches to enhance the antifungal activity of statins against mucosal candidiasis, providing a framework for future translational research and clinical application. The rising prevalence of antifungal resistance and virulence factors of Candida albicans underscore the limitations of current therapies. Statins, commonly used as lipid-lowering agents, have emerged as attractive repurposed drug candidates due to their ability to interfere with fungal ergosterol biosynthesis and Ras-mediated signaling pathways.

Arrowroot starch has been modified using ozone, heat-moisture treatment (HMT), and their sequential combinations. Both treatments increase solubility, water absorption capacity (WAC), and adhesiveness, while reducing pasting viscosities. Ozone treatment also enhances brightness, hardness, gumminess, chewiness, and freeze-thaw stability (0.
