SUMMARY The short-term effect of topical application of anthralin (dithranol) on normal human skin was investigated by electron microscopy. Mitochondria appeared markedly damaged. By contrast other cellular structures, particularly the nuclear and cy

Neutral red is a lysosomal probe and a biological pH indicator. In aqueous solutions, the protonated (NRH) and neutral (NR) forms of monomeric neutral red exhibit distinct absorption maxima (535 and 450 nm, respectively) but have the same fluorescenc

The singlet and the triplet excited states parameters of psoralen and derivatives, 4,6,4′-trimethylangelicin and 4,5′,8-trimethylpsoralen, show an extreme sensivity to solvent polarity in dioxane/water mixtures. The internal conversion rate const

5-Geranoxypsoralen, commonly called bergamottin, a major furocoumarin contained in bergamot oil, is reported in vitro as a highly photoreactive psoralen. In ethanol, it exhibits quite a high triplet state quantum yield (approximately 0.37). The tripl

The E⇄ Z photoisomerization of 4′-methoxycinnamates, used as sunscreens in cosmetics, has been studied by steady state and laser flash photolysis, in aqueous and organic solutions. Photoisomerization quantum yields are found to be fairly high (˜

Most photobiological studies concerning psoralens, 5M0P and 8M0P, were performed with the aim of characterizing its action at cellular level, as they are potent skin photosensitizers used in photochemiotherapy. In this way, much more is known on phot
