THE EFFECT OF TRIALKYLTIN COMPOUNDS ON TUBULIN POLYMERISATION
Journal of Neurochemistry, 1978 AbstractThe effects of trialkyltin compounds on the colchicine‐binding activity and the in vitro polymerisation of rat brain tubulin have been investigated. Trialkyltins at concentrations between 10 and 100 μM inhibited the colchicine‐binding activity of purified tubulin preparations derived from rat brain.

The interactions of trialkyltin compounds with lysosomes from rat liver
Journal of Inorganic Biochemistry, 2000 Interactions of two trialkyltin compounds with the lysosomes from a rat liver have been studied. It is shown that these compounds induce a fast alkalinisation in the matrix of energised lysosomes. The fast alkalinisation rate is similar to the one obtained with uncouplers of the oxidative phosphorylation.

Direct Synthesis of Organotin Compounds V. Di- and trialkyltin chlorides and bromides
Journal of Organometallic Chemistry, 1967 Abstract Di- and trialkyltin chlorides were prepared in good yields by the direct reaction of alkyl chloride with metallic tin when organic ammonium halides or a mixture of organic base and iodine-compound was used as the catalysts. Distribution of di- and trialkyltin chlorides varied with the kind and the amount of organic base, and reaction ...

A proposal for a new mechanism of interaction of trialkyltin (TAT) compounds with mitochondria
Journal of Inorganic Biochemistry, 1997 The interactions of trialkyltin (TAT) compounds with the mitochondria were largely studied. The current view of this phenomenon is that these compounds, by exploiting the Cl− and OH− gradient in energised mitochondria, behave as electroneutral OH−/Cl− exchangers. Experiments performed with triethyltin-, tripropyltin-, and tributyltin-chloride, allow us

Journal of Chromatography A, 1984 An analytical procedure for the determination of trialkyltin (tributyltin, tripropyltin), triphenyltin and dialkyltin (dibutyltin) compounds in environmental water and sediment was studied. Water samples were extracted into benzene with hydrochloric acid and sodium chloride.

Journal of Organometallic Chemistry, 1991 Abstract The mixed triorganotin compounds which combine two different trialkyltin moieties (R 3 Sn and R′ 3 Sn) in the same molecule have been synthesized using trialkyltin derivatives of sulphomaleic and 4-sulphophthalic anhydrides as starting materials.

Journal of Toxicology and Environmental Health - Part A: Current Issues, 1982 The intestinal uptake site, enterohepatic circulation, and excretion into bile, feces, and urine of alkyltins (tetra and trialkyltin) were investigated after oral, sc, or intestinal administration of the compounds to rats and rabbits. Assays of tetra- and trialkyltins in biological materials were carried out by gas chromatography. The main uptake sites

An Investigation of the Interaction of Trialkyltin Compounds with Humic Acids
, 1991 As previous work has shown, the trialkyltin compounds are more toxic than their inorganic homologs [1,2] and thus, their behaviour in the environment should be investigated. Humic acids are widely distributed in soils and have diverse roles within geochemistry [3]. They combine with toxic metals and thus change the mobility and bioavailability of these

Investigations on organotin compounds XVII: The structure of trialkyltin acylates
Recueil Des Travaux Chimiques Des Pays-Bas, 1963 AbstractBy infrared spectroscopy it is shown that trialkyltin acylates in the solid state occur as coordination polymers in which each tin atom is penta‐coordinated,viz. by three alkyl groups and two oxygen atoms belonging to different acylate groups.
