Hematoporphyrin derivative: experimental evidence for aggregated species
Chemical Physics Letters, 1982Abstract Absorption and fluorescence properties of hematoporphyrin derivative in different solvent systems are investigated. The presence of a large amount of stable aggregates is demonstrated. The existence of these aggregates represents one major difference between hematoporphyrin derivative and hematoporphyrin free base.

On the Preparation of Dihematoporphyrin Ether-Free Hematoporphyrin Derivative
Biological Chemistry Hoppe-Seyler, 1988A dihematoporphyrin ether-free hematoporphyrin derivative has been prepared by a base-catalysed dehydration of hematoporphyrin with sodium hydroxide. The identification was performed by HPLC and mass spectroscopy (FD-MS). The reaction of hematoporphyrin with 1 M sodium hydroxide for 24 h yields more than 90% of the monomeric porphyrins.

Hematoporphyrin Derivative in the Diagnosis and Treatment of Lung Cancer
1983Since 1978 we have studied the properties of hematopor-phyrin derivative (HPD) and have sought means to improve the drug as well as the instrumentation used in both diagnostic and therapeutic clinical procedures (1–3).

[Synergism of hyperthermia and hematoporphyrin derivative].
Gan to kagaku ryoho. Cancer & chemotherapy, 1984Much attention has been given to the photoradiation therapy, since its mechanism of effect is thought to be due to the cytotoxicity of singlet oxygen produced from hematoporphyrin derivative (HPD) by the light. We studied the effects of hyperthermia (HT) on cultured cells (T1) of ethylnitrosourea induced rat brain tumor which had uptaken HPD, because ...

Hematoporphyrin Derivative: Fluorometric Studies in Solution and Cells
1984Hematoporphyrin Derivative (HpD) is a mixture of porphyrins, widely used in detection and therapy of cancer1,2. HpD was introduced in 1961 by Lipson et al.3 as a better tumor-locating drug than Hematoporphyrin (Hp). They proposed that the crude Hp be treated with a mixture of acetic acid and sulfuric acid, followed by adjustment of the final pH to ...
