The mutagenic effects of monofunctional and bifunctional furocoumarins (psoralens) plus 365 nm radiation were analyzed in the yeast Saccharomyces cerevisiae. Per unit dose of 365-nm radiation, bifunctional compounds were more effective than were the monofunctional for the induction of reverse and forward mutations. The same was observed for the induction of 6-thioguanine-resistant mutants in V79 Chinese hamster cells when we compared the activity of 8-methoxypsoralen and 3-carbethoxypsoralen. An analysis of the kinetics of mutation induction indicated that DNA interstrand cross-links induced by bifunctional psoralens are more prone to error than are monoadducts induced by monofunctional psoralens. In yeast, 8-methoxypsoralen and 4,5'-dimethylangelicin were shown to photoinduce mitotic and nondisjunction. The implications of these findings for the use of psoralens in photochemotherapy and cosmetics are discussed.
