Redox and fungicidal properties of phthalocyanine metal complexes as related to active oxygen.

Some chemical and fungicidal effects of 20 phthalocyanines of Co, Fe, Cu, and Al were studied. Under dark conditions, these complexes reduced nitroblue tetrazolium in the presence of KCN, accelerated the autoxidation of ascorbate or hydroquinone and decomposed hydrogen peroxide. In the later reaction, hydroxyl radical was generated as evidenced with the deoxyribose assay.

[Structure formation of water insoluble fullerene amino acid derivatives in organic solvents].

The time-dependent structure formation of the fullerene derivative of p-amino benzoic acid in organic solvents was studied by scanning electron microscopy. It was shown that, during storage of solutions, the structures are destroyed.

Membranotropic properties of the water soluble amino acid and peptide derivatives of fullerene C60.

The modifying effects of the products of the equimolar addition Of DL-alanine and DL-alanyl-DL-alanine to fullerene C60 on the structure and permeability of the lipid bilayer of phosphatidylcholine liposomes has been studied using the luminescence probe technique. It is shown that these water soluble amino acid and dipeptide derivatives of fullerene (C60-AD) are quenchers of pyrene fluorescence and erythrosine phosphorescence of in both a water solution and liposomes. To study the permeability of the lipid bilayer a procedure based on the triplet probe technique has been developed.
