Abstract
The tumor-localizing components of the porphyrin preparation, hematoporphyrin derivative, were characterized using aqueous and nonaqueous gel exclusion and reverse-phase chromatography. Localization is mediated by hematoporphyrin derivative components which are among the most hydrophobic in the preparation. This apparent hydrophobicity may derive from hydrogen-bonding phenomena, rather than from absence of hydrophilic functional groups. [Hematoporphyrin derivative is a radiosensitizer useful in treating cancer.].
