Beschreibung
Zusammenfassung:	Disclosed is a method and a pharmaceutical composition for killing mammalian tumor cells by subjecting the cells to light in the presence of a light-activatable tetrapyrrole, in which the improvement comprises treating the cells with a compound which inhibits the enzymatic conversion of protoporphyrinogen to protoporphyrin IX by protoporphyrinogen oxidase in the cells thereby causing a buildup of protoporphyrin IX in the cells. Also disclosed is a method for the production of protoporphyrin IX which comprises growing eukaryotic microalgae in the presence of a protoporphyrinogen oxidase inhibitor.
