Concise Total Synthesis of (+)-Asperazine, (+)-Pestalazine A, and (+)-iso-Pestalazine A. Structure Revision of (+)-Pestalazine A [PDF]
, 2015 The concise, enantioselective total syntheses of (+)-asperazine (1), (+)-iso-pestalazine A (2), and (+)-pestalazine A (3) have been achieved by the development of a late-stage C3–C8′ Friedel–Crafts union of polycyclic diketopiperazines.

Plant Biotechnology Journal, EarlyView.ABSTRACT Cold stress threatens wheat productivity, particularly in regions with extreme climatic conditions. To elucidate the molecular mechanisms underlying wheat's response to cold stress, we performed a multiomics analysis integrating lipidomics, transcriptomics, proteomics and metabolomics.

Angewandte Chemie, Volume 138, Issue 15, 6 April 2026.A gram‐scale supply of bulbiferamide A, which features a rare N‐acylindole linkage and possesses potent inhibitory activity against Trypanosoma cruzi epimastigotes (IC50 = 4.1 µM)—the causative parasite of Chagas disease—was successfully achieved. Moreover, the cyclization strategy developed in this study facilitated the synthesis of noncanonical ...

Plant Biotechnology Journal, EarlyView.ABSTRACT Mentha spicata L. (spearmint) is a high‐value aromatic and medicinal species, whose productivity is strongly affected by water deficit. Nevertheless, the molecular mechanisms underlying drought acclimation in this mint remain largely unexplored. Thus, here, we investigated the microRNA‐mediated regulatory processes triggered in M.

Plant Biotechnology Journal, EarlyView.ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

Plant, Cell &Environment, EarlyView.ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

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 ...
