SYNTHESIS OF FLUORINE ANALOGS OF HEMATOPORPHYRIN

With the aim of obtaining a porphyrin derivative useful for diagnosis and therapy of cancer, fluorine analogs of hematoporphyrin, which had trifluorohydroxyethyl group(s) in the place of hydroxyethyl groups, we re synthesized by the reaction of deuteroporphyrin dimethyl ester with trifluoroacetaldehyde in the presence of aluminum chloride. Prelimina ry results of biological tests of the products showed that the hexaflu oro analog of hematoporphyrin accumulates to Human liver cancer cells more selectively than other fluorine analogs.
