Biological activities of phthalocyanines--X. Syntheses and analyses of sulfonated phthalocyanines.
Synthetic methods to obtain selectively sulfonated metallo phthalocyanines are compared. Both condensation and direct sulfonation procedures lead to mixtures of monoto tetrasulfonated products which are resolved by reverse phase liquid chromatography in buffered aqueous-methanol. The proportion of sulfonated derivatives is examined as a function of the starting reagents in the case of the conde...
متن کاملBiological Activities of Phthalocyanines-viii. Cells and Phototoxicity of Selectively Sulfonated Aluminum Phthalocyanines Cellular Distribution in V-79 Chinese Hamster
Water soluble chloro aluminum phthalocyanines sulfonated to different degrees are studied for phototoxicity and cellular distribution in V-79 Chinese hamster cells. The more hydrophobic disulfonated dyes, with sulfonate substituents on adjacent benzyl groups of the phthalocyanine ring structure, exhibited the best cell penetrating properties and the highest phototoxicity. Fluorescence microscop...
متن کاملFacile synthesis of pegylated zinc(II) phthalocyanines via transesterification and their in vitro photodynamic activities.
Treatment of 4,5-bis[4-(methoxycarbonyl)phenoxy]phthalonitrile and 4,5-bis[3,5-bis(methoxycarbonyl)phenoxy]phthalonitrile with an excess of 1,3-diiminoisoindoline in the presence of Zn(OAc)(2)·2H(2)O and 1,8-diazabicyclo[5.4.0]undec-7-ene in triethylene glycol monomethyl ether or polyethylene glycol monomethyl ether (with an average molecular weight of 550) led to "3 + 1" mixed cyclisation and ...
متن کاملNonlinear optical absorption of zinc-phthalocyanines in polymeric matrix
We realized and investigated films of zinc-phtalocyanines into poly(methylmethacrylate) (PMMA) for optical limiting applications. The ratio by weight of the compound to the host polymer was 0.083% and 0.15%. Linear optical characterization of films, performed by spectrophotometry, show a low degree of molecular aggregation of zinc-phtalocyanines in the polymeric matrix. Two different type of no...
متن کاملHighly photocytotoxic 1,4-dipegylated zinc(II) phthalocyanines. Effects of the chain length on the in vitro photodynamic activities.
A new series of 1,4-dipegylated zinc(II) phthalocyanines have been synthesised and spectroscopically characterised. The derivatives ZnPc[O(CH(2)CH(2)O)(n)Me](2) (n = 2, 4, ca. 12) have been prepared by mixed cyclisation of the corresponding disubstituted phthalonitriles with an excess of unsubstituted phthalonitrile in the presence of Zn(OAc)(2) x 2 H(2)O and 1,8-diazabicyclo[5.4.0]undec-7-ene....
