In recent years, amino acid-based biomass adhesive systems have garnered attention due to their unique structures and biobased feedstocks. However, they still face challenges such as insufficient wetting and mechanical properties, poor mold resistance, and environmental concerns. To address such challenges, this paper proposes a rapid construction strategy for eutectic solvents (ES)-mediated amino acid-based green adhesives. Four amino acid-based adhesives were prepared by polymerization with vanillin in its green ES with organic superbase, and each adhesive exhibited high dry bonding strength as adhesives, with the highest reaching 4.82 MPa (dry shear strength). Additionally, we innovatively incorporate discarded rose branches as a woody filler to develop a biomass composite material exhibiting outstanding mechanical properties, thermal insulation, mold resistance, and biodegradability.

Building on gossyzid, a pH-activatable imine prodrug of the polyphenolic aldehyde gossypol, we introduce a family of gossyzid–metal conjugates (GMCs) that implement orthogonal masking: gossypol is first protected as gossyzid, then “locked” within coordination environments formed with first-row transition metal ions (Mn, Fe, Co, Ni, Cu, and Zn). Spectroscopic analyses, powder x-ray diffraction, and thermogravimetric profiling support the formation of coordination architectures, rationalizing the mass-spectrometric intractability of these species. Photophysical studies reveal metal-dependent binding stoichiometries and affinities, establishing a tunable stability series across the GMCs. Using amino acids as competitive chelators, we demonstrate selective, triggerable de-chelation of the metal node that regenerates gossyzid under tumor-mimicking conditions; subsequent tumor-microenvironment (TME)-relevant acidolysis completes its activation to gossypol. Notably, only specific amino acids effectively unmask defined GMC subsets, enabling control over activation kinetics and extent. In triple-negative breast cancer models, GMC cytotoxicity correlates with intrinsic metal–ligand binding, thus showing the contributions of double masking. To our knowledge, this is the first systematic demonstration of amino-acid-triggered activation in double-masked metal–prodrug conjugates, with direct implications for the design of next-generation, TME-responsive prodrugs.\u0000 </div>","PeriodicalId":145,"journal":{"name":"Chemistry - An Asian Journal","volume":"21 18","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149072947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sr@HF also exhibited a larger apparent rate constant (0.0216 min−1) than Ba@HF (0.0133 min−1), which shows better photocatalytic activity.
