Structure-Affected Bioactivity of Triorganotin Compounds
نویسنده
چکیده
The biocidal activity of 8 triorganotins R3S11X (R = butyl, phenyl, benzyl; X = oxide, chloride, acetate, naphthenate, TV, JV-diethyldithiocarbamate) on brown rot fungi, moulds mixture, benthic organisms, plankton alga Scenedesmus quadricauda, and crop plant has been investigated. The results suggest dependence between lipophilicity of bounded R groups and intensity of unfavourable effect. The most effective triorganotins were compounds with butyl group in n-alkyl chain, the least active were the tribenzyltins. In general, independently on the investigated biological object, the strongest biocidal activity was shown by bis(tributyltin) oxide whereas the lowest inhibitory efficiency was exhibited by tributyltin naphthenate. The effect of X group on biocidal activity was not significantly manifested.

Organotin compounds are typical environmental contaminants and suspected endocrine-disrupting substances, which cause irreversible sexual abnormality in female mollusks, called "imposex". However, little is known about the capability of triorganotin compounds, such as tributyltin and triphenyltin, to cause disorders in the sexual development and reproductive functions of mammals, including huma...
