5‐HT2A receptor agonism by tert‐leucinamide and valinamide synthetic cannabinoids: In vitro and in vivo evidence

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose New synthetic cannabinoid receptor agonists (SCRAs) are associated with severe adverse effects, including unexpected psychiatric symptoms. These compounds are mainly active through their potent agonism on the cannabinoid receptors CB1 and CB2.

Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Ultra‐High Strength and Environmentally Stable Fluorinated Solid‐State Ion‐Conductive Elastomers with Folding‐Paper‐Structured Triboelectric Nanogenerators for Wave Energy Harvesting

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
In this work, a polyurethane‐based fluorinated SICEs with excellent mechanical properties (7.35 MPa and 61.4 MJ m−3), conductivity (4.2 × 10−4 S cm−1), and harsh environmental resistance were prepared by a “three birds with one stone” strategy that combines multiple interactions with fluorine effects. The paper‐folding TENG is capable of harvesting not

An Exploration of Vinamidinium Salts for Frame‐Shifted Synthesis

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
Oligoheterocycles are widely used in drug discovery and materials science, where they serve as attractive alternatives to peptide fragments. There is strong interest in understanding the structural correspondence between heterocycles and amino acid motifs to recapitulate key binding elements while improving metabolic stability.

Chemical Syntheses of 3′ and 5′ Phosphorylated Oligonucleotides: An Overview

European Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
This review provides an overview of the various chemical methods employed in the synthesis of oligonucleotides bearing a phosphate group at their 3′ or 5′ end. Notably, it presents modified phosphoramidites and supports developed for this purpose. Oligonucleotides (ON) with a phosphate monoester group at their 3′ or 5′ end have applications in many ...
