The physiological and hemolytic toxicities of triphenyllead chloride (TPhL) as well as its modifying influence on model lipid membranes were studied. The experiments allowed the determination of TPhL concentrations causing 50% inhibition of growth of Spirodela oligorrhiza, Lemna minor and Salvinia natans (EC50), 100% hemolysis of pig erythrocytes (C100) and(More)
The hemolytic activity of some newly synthesized aminomethanephosphonic acid derivatives was studied. The compounds studied differed in their polarity and the hydrophobicity of the electronic substituents at their nitrogen and carbon atoms. It was found that acyclic aminophosphonates exhibited significantly stronger hemolytic properties than cyclic(More)
Xenobiotic exposure may induce cell membrane injury which would affect cellular structures and function. This study examined the influence of new aminophosphonates, synthesized for agrochemical application, on biological and model membranes properties. The aminophosphonates differed in the substituents on their carbon, nitrogen and phosphorus atoms.(More)
Newly synthesized derivatives of α-aminoalkanephosphonic acids (aminophosphonates) differ in the substituents at the carbon, nitrogen, and phosphorus atoms. They modified in different degree the properties of cucumber (Cucumis sativus cv. Wisconsin) cotyledon membranes, physiological activity of some enzymes (guaiacol and pyrogallol peroxidases, and(More)
The influence of a series of acyclic and cyclic aminophosphonates on the physicochemical properties of model (planar lipid membranes-BLM) and biological (erythrocytes-RBC) membranes was studied. The results obtained were compared with the results of physiological tests performed on the aquatic plant Spirodela oligorrhiza. It was found that the inhibition of(More)
Influence of some new aminophosphonates on electrolyte leakage from cucumber (Cucumis sativus cv "Wisconsin") cotyledons as well as on the content of chlorophyll and activity of guaiacol and pyrogallol peroxidase were studied. Concentration of malondialdehyde (MDA), one of the end-products of lipid peroxidation, was also measured. It was found that(More)
