Effect of tin and lead chlorotriphenyl analogues on fruit fly Drosophila hydei and liposomes membrane
2011
This article presents the results of a study investigating the biological activity of triphenyltin chloride (TPhT) and two metalloorganic compounds, triphenyllead chloride (TPhL) and triphenylmethane chloride (TPhC), in their interaction with model membranes and the living organisms of fruit flies Drosophila hydei. The study of model membranes (sonicated liposomes) was conducted using the electron spin resonance (ESR) spin probe technique, whereas the experiment on fruit flies involved investigating their viability on media containing the studied compounds. The test results clearly demonstrate that TPhT affects fruit flies more actively than TPhL (complete lethality after 7 days of culture …
Effect of Chlorotriphenyl Derivatives of Sn and Pb upon Biophysical Properties of Membranes
2009
Biophysical activity of two twin organometallic compounds Triphenyltin chloride (TPhT) and Triphenyllead chloride (TPhL) in their interreaction with model membranes, as well as with yeast cellsSaccharomyces cerevisiae, was investigated. Four measurement methods were used in the experiments: two physical methods (spin probes method and the electric method); two biological methods (minimal inhibitory concentration /MIC/ and yeast survival test). It has been found that the activity of TPhT in interaction with model membranes and yeast cells is distinctly greater than that of TPhL. The activity manifests itself by considerable increase in the fluidity of the middle part of liposome bilayer, cha…
Characterization of some triphenyltin(IV) complexes of 5-(arylazo)salicylaldehyde ligands using IR, 1H, 13C, 119Sn NMR and 119Sn Mössbauer spectrosco…
1994
Abstract Coordination complexes of 5-(arylazo)salicylaldehyde with triphenyltin chloride have been prepared and subjected to IR, multinuclear NMR (1H, 13C, 119Sn) and 119Sn Mossbauer spectroscopy. 5-(Arylazo)salicylaldehyde forms two types of complexes viz. triorganotin adducts and phenoxides. In the adducts, the protonated ligand coordinates through the aldehydic oxygen atom while in phenoxides, the coordination occurs via the phenolic oxygen atom and the oxygen atom of the aldehydic group. The spectroscopic data suggest that both types of complexes adopt a cis-trigonal bipyramidal geometry around tin.
