Open publisher page 0 citations

Abstract

More attention has been paid to hematoporphyrin derivative (HPD), an useful porphyrin photosensitizer used in tumor detection and treatment.Although the photosensitization of Photofrin Ⅱ and YHPD made in China is higher than that of HPD, the percentages of some of their porphyrin components are greatly different. This raises questions. Which porphyrin component is active? Why is it active? International photochemical and medical scientists have been discussing the chemical structure, biological
