A Convenient One‐Pot CuI‐Catalyzed Procedure for the Synthesis of S‐(N‐Heteroaryl) Thiocarboxylates From N‐Heteroaryl Bromides and Thiobenzoic Acid

ChemistryOpen, Volume 15, Issue 4, April 2026.
A one‐pot two‐step CuI‐catalyzed procedure for the synthesis of S‐(N‐heteroaryl) thiocarboxylates from N‐heteroaryl bromides and thiobenzoic acid was developed, which is highlighted by shorter reaction time, a smaller amount of iodide source and scalability.

Ewangoa, a new threatened Central African genus of Euphorbiaceae‐Acalyphoideae

TAXON, Volume 75, Issue 2, April 2026.
Abstract A new morphologically divergent genus and species of Euphorbiaceae from the Democratic Republic of the Congo, Ewangoa cardiophora, is described and illustrated. This taxon is easily recognised by its leaf‐opposed inflorescences, which are surrounded by a single cordiform involucral bract. Molecular phylogenetic evidence shows that Ewangoa is a

Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

TAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

Factors Influencing Undesirable Sensory Properties in Protein Hydrolysates and Remediation Strategies for Food Applications

Journal of Food Science, Volume 91, Issue 4, April 2026.
ABSTRACT Enzymatic hydrolysis is used to produce protein hydrolysates from animal‐ and plant‐based sources, which are widely utilized in industry due to their nutritional, functional, and bioactive properties. However, these hydrolysates can exhibit unattractive sensory properties, such as off‐flavors or off‐odors, which limit their use in food ...

Senescence‐Driven IL‐17A Inflammatory Circuit Promotes Epithelial–Mesenchymal Transition (EMT) and Progression in Age‐Related Posterior Subcapsular Cataracts

Aging Cell, Volume 25, Issue 4, April 2026.
Using multi‐region human PSC samples, we identified EMT as a consistent pathological feature. Mechanistically, senescent LECs secrete IL‐17A, a representative SASP factor, which activates NF‐κB signaling. NF‐κB further amplifies SASP production, thereby establishing a senescence–inflammation feedback loop that drives EMT, sustains pathological ...
