Ultraviolet radiation of 8-methoxypsoralen (8-MOP) in the presence of various polyamines resulted in stable photoproducts that were very soluble in water and showed hyaluronidase-activating properties. Among them, the photoproducts obtained from the reaction systems of 8-MOP-spermine and 8-MOP-spermidine markedly activated hyaluronidase. The enzyme activity was not affected by 8-MOP alone and the photoproduct of 8-MOP (8-MOP-P). From these facts, it was suggested that the photoproducts with hyaluronidase-activating properties might play an important role in the onset of 8-MOP-induced photosensitivity.

The effects of UVA and chlorpromazine on the activity of hyaluronidase were investigated. Hyaluronidase was slightly activated by UVA alone. It was also activated by chlorpromazine, but the activation was enhanced by concomitant UVA irradiation. By pre-irradiation of chlorpromazine, it was found that a stable photoproduct of chlorpromazine was formed that activated hyaluronidase. As activation of hyaluronidase has been described in relation to tissue inflammation, the onset of chlorpromazine-induced photosensitivity may, in part, be related to the hyaluronidase activating effect of chlorpromazine plus UVA.
