Synthesis and characterization of furfural-functionalized poly(vinyl alcohol) cross-linked with maleimide bearing tributyltin groups

eXPRESS Polymer Letters, 2022
In the present work, new cross-linked networks based on furfural-functionalized poly(vinyl alcohol) (PVF) and maleimide compounds containing tributyltin groups were synthesized. The networks were obtained both as films and porous membranes. The structure

Tributyltin Protumorigenic Effects Targeting Prostate Cancer Cell Metabolism, Proliferation, Migration, and Invasion

Environmental Toxicology, Volume 41, Issue 9, Page 709-729, September 2026.
ABSTRACT Prostate cancer (PCa) is an endocrine‐related cancer highly dependent on androgenic signaling. Beyond hormone dependence, extrinsic factors play a significant role in the risk of developing PCa, which raises concern about the influence of environmental compounds such as endocrine‐disrupting chemicals (EDCs). Tributyltin (TBT) is an EDC used in

Zebrafish obesogenic test: a tool for screening molecules that target adiposity

Journal of Lipid Research, 2011
Dietary and xenobiotic compounds may alter endocrine signaling and lipid homeostasis, thus inducing obesity. We describe a short-term assay method, the zebrafish obesogenic (ZO) test, for examining the effects of diet, drugs, and environmental ...

Bioaccumulation of Tributyltin by Blue Crabs

Journal of the Brazilian Chemical Society, 2013
This study evaluated the bioaccumulation of tributyltin (TBT) by the blue crab (Callinectes sapidus). Animals were fed with contaminated food containing 30 µg g-1 of TBT expressed as Sn. The analytes were determined in the gills, hepatopancreas and muscle. Acid digestion was used in the total Sn determination, and a solid-phase extraction technique was

Visible‐Light Photoredox Catalysis in the Intramolecular Dicarbonylation of Alkenes: Catalyst‐Dependent Divergent Syntheses of Both 1,4‐Dicarbonyls and α‐Hydroxy‐β,γ‐Unsaturated Lactams From 1,2‐Dicarbonyls

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
Catalyst‐dependent divergent syntheses were developed. Intramolecular dicarbonylation of vinyl halides under metal‐free either thermal or visible light photocatalytic conditions were explored to produce a series of 1,4‐dicarbonyls with two different carbonyl moieties and a lactam ring.

First Structural Determination of an Isolable and Planar Tropyl Radical

ChemistryEurope, Volume 4, Issue 8, August 2026.
Isolation of a persistent bianthryl‐substituted dibenzotropyl radical enabled the first crystallographic verification of a planar hydrocarbon‐based tropyl radical. Spectroelectrochemical studies revealed reversible redox interconversion between the cationic and radical states while retaining the planar seven‐membered framework. Planar hydrocarbon‐based

Monitoring the Effect of Tributyltin Salicylate and Propionate, Retinoid X Receptor Ligands, on Heat Shock Protein Expression in MDA‐MB‐231 Cells by MALDI MS/MS

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT Organotin (IV) compounds are known to induce apoptosis via the intrinsic mitochondrial pathway, which is a key mechanism of effective anticancer therapy. Their ability to selectively promote apoptotic cell death highlights their potential as chemotherapeutic agents. In this study, the in vitro effects of two triorganotin compounds, tributyltin
