Title
(EN) USE OF PORPHINE CATIONIC DERIVATIVE SALTS AS GRAM-NEGATIVE BACTERIA PHOTOSENSITIZERS
(FR) UTILISATION DE SELS DE DERIVES CATIONIQUES DE PORPHINE COMME AGENTS PHOTOSENSIBILISANTS DE BACTERIES DE TYPE GRAM-NEGATIF
Abstract
(EN)
Use of porphine cationic derivative salts as gram-negative bacteria photosensitizers. These salts are of general formula (I) in which R1, R2, R3, R4, which are the same or different, are a hydrogen atom, a phenyl radical or a radical having one of the formulas (i) (ii), and (iii); X- is a monovalent anion with the proviso that one at least of the R1, R2, R3 or R4 radicals is a radical of formula (i) to (iii) except for R1, R2, R3 and R4, which are the same and are the radical of formula (i). Contamination of the substrate can be reduced by treating the substrate with a salt of formula (I) and then subjecting it to light irradiation.
(FR)
Utilisation comme agents photosensibilisants de bactéries de type gram-négatif, de sels de dérivés cationiques de porphine. Ces sels répondent à la formule générale (I), dans laquelle R1, R2, R3, R4, identiques ou différents, représentent un atome d'hydrogène, un radical phényle ou un radical ayant l'une des formules (i), (ii), et (iii); X- représentant un anion monovalent, sous réserve que l'un au moins des radicaux R1, R2, R3 ou R4 représente l'un des radicaux de formule (i) à (iii) mais à l'exclusion de R1, R2, R3 et R4 identiques et représentant le radical de formule (i). En traitant un substrat avec un sel de formule (I), puis en le soumettant à une irradiation lumineuse, on peut réduire la contamination de ce substrat.
