On the mechanism of erythrocyte hemolysis induced by photooxidized psoralen

Contemporary concepts on a possible mechanism of erythrocyte hemolysis induced by photooxidized psoralen - the medicinal photosensitizing furocoumarin - are reviewed. The hypothesis on the mechanochemical mechanism of hemolysis is considered in view of recent data on photoinduced aggregation in photooxidized psoralen solutions. Appropriate chemical structures of photoproduct hemolysins and aggregating photoproducts are discussed.
