Nature of the tumor-localizing components of hematoporphyrin derivative.

Abstract

Hematoporphyrin derivative linked by ether bonds (HE) was synthesized by unambiguous procedures in order to compare its properties to hematoporphyrin derivative (HpD). Reverse phase high performance liquid and gel filtration chromatography were used to compare the HE derivatives to HpD. The cellular uptake of HE derivatives was compared to HpD using the… (More)
