The mutagenicity and micronucleus induction by the furocoumarin hydroperoxides 1a and 2a and, for comparison, their corresponding alcohols 1b and 2b were investigated in L5178Y tk+/- mouse lymphoma cells and AS52 Chinese hamster ovary cells. The furocoumarin hydroperoxide 1a enhanced the micronucleus frequency in L5178Y tk+/- mouse lymphoma cells significantly, while its alcohol 1b exhibited a rather moderate effect. In contrast, both the furocoumarin hydroperoxide 2a and its alcohol 2b induced high frequencies of micronuclei. Only the furocoumarin hydroperoxide 1a, but not its alcohol 1b, was mutagenic in both L5178Y tk+/- and AS52 cells. On the other hand, the furocoumarin hydroperoxide 2a and its alcohol 2b were mutagenic. For all furocoumarin derivatives 1a,b and 2a,b no mutagenicity and genotoxicity was observed in the absence of UVA light. The multifunctional furocoumarin hydroperoxides may serve as potential photochemotherapeutic agents.
