title: Mutagenicity in Salmonella typhimurium of some angelicin derivatives proposed as new monofunctional agents for the photochemotherapy of psoriasis.
abstract: A series of angelicin derivatives were tested for their mutagenic activity with and without near-ultraviolet irradiation (NUV) in Salmonella typhimurium strains. After irradiation with NUV, the tested compounds induced different numbers of revertants in strain TA100, indicating that the mutational events involved are base substitutions. In the dark, 3 chemicals behaved as frame-shift mutagens causing reversion in strain TA98.
