The case against tributyltin [PDF]

Oryx, 1986
The use of paints containing tributyltin (TBT) to keep boat hulls clean is threatening marine life in some coastal regions, especially where boating for pleasure is popular. Research so far has shown that very low concentrations of the chemical have lethal or mutagenic effects on some marine invertebrates and stop the growth of phytoplankton ...

C4 Functionalization of the Isoquinoline Core via Oxidative Radical Substitution

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.
The isoquinoline ring can be easily functionalized at C‐4 through a radical‐oxidative substitution process. The resulting products can be readily cyclized under basic conditions, facilitating the construction of pyranones fused to the isoquinoline scaffold. ABSTRACTIn this work, we report a straightforward synthetic procedure that enables the selective

Tributyltin: A Bottom–Up Regulator of the Crangon crangon Population?

Frontiers in Marine Science, 2019
The restrictions and the concerted action of the global ban on the use and presence of tributyltin (TBT) in marine applications to protect ecosystems in the marine environment in 2008 was mainly based on the economic impact on shellfish industries and ...

Scratch‐Healing of Conjugated Polymers: Flexibly Linked PTB7‐Th Copolymers and Their Blends

Macromolecular Chemistry and Physics, Volume 227, Issue 9, 15 May 2026.
Flexibly‐linked conjugated polymers based on the donor polymer PTB7‐Th are capable of scratch healing. A higher linker content leads to higher “mobility,” which is required for the healing process. However, the optical properties are impaired. Blends of donor polymers with high and low linker content can solve this dilemma as they provide sufficient ...

Comparative Study of Tributyltin Adsorption onto Mesoporous Silica Functionalized with Calix[4]arene, p-tert-Butylcalix[4]arene and p-Sulfonatocalix[4]arene

Molecules, 2014
The adsorption of tributyltin (TBT), onto three mesoporous silica adsorbents functionalized with calix[4]arene, p-tert-butylcalix[4]arene and p-sulfonatocalix[4]arene (MCM-TDI-C4, MCM-TDI-PC4 and MCM-TDI-C4S, respectively) has been compared.

Pharmacological property of tributyltin in vivo and in vitro [PDF]

Environmental Toxicology and Pharmacology, 2000
Tributyltin (TBT), an assumed endocrine-disrupting chemical, is widely known to show harmful effects in invertebrates including the dioecious snails. As for mammals, there are several reports concerning TBT toxicology, but few indications about general pharmacology of TBT. In the present study, we comprehensively examined the pharmacological effects of

Surficial N+ Charge Density as Key Factor for Inhibition of Pseudomonas Biofilm Formation in Non‐Leaching Quaternary Ammonium‐Modified Polydimethylsiloxane Coatings

Chemistry – A European Journal, Volume 32, Issue 14, 15 April 2026.
Biological fouling threatens marine ecosystems and infrastructures, demanding sustainable solutions. We designed PDMS materials functionalized with quaternary ammonium‐based silanes that inhibit biofilm formation of a highly resilient Gram‐negative Pseudomonas strain.

Organotin compounds in marine water and sediments from the port of Ensenada, Baja California, Mexico

Ciencias Marinas, 1997
 During September and October 1995, samples of surface sediments and water were collected to develop an analytical set-up to determine the concentrations of the organic compounds known as tributyltins (TBTs), including tributyl-, dibutyl- and ...

Environmental Toxicity Assessment of Organotin Compounds Using the Direct Contact Bioassay – OSTRACODTOXKIT F

Journal of Education, Health and Sport
The aim of the study was to assess the toxicity of organic compound of tin using two tests with Heterocypris incongruens. Chlorides: tributyltin, trimethyltins and triphenyltin were tested by conducted acute (mortality) and chronic toxicity tests ...

Mapping molluscan endocrinology: a systematic and critical appraisal

Biological Reviews, Volume 101, Issue 2, Page 970-1002, April 2026.
ABSTRACT Historically, a vertebrate‐centric paradigm has framed our interpretation of molluscan endocrinology, with considerable research focusing on vertebrate‐type steroid hormones (e.g. oestrogens, testosterone). However, contradictory evidence on the occurrence of vertebrate‐type steroid hormones in molluscan tissues, and a lack of the specific ...
