Inhibition of bergapten toxicity by UV-A filters

Inhibition of bergapten toxicity by UV-A filters. Saettone, M. F.; Trambusti, M.; Giannaccini, B. 63250-25-9 and 70356-09-1 are also occured in this study. (Fac. Pharm., Univ. Pise, Pisa 56100, Italy). Int. J. Cosmet. Sci., 5(5), 201-13 (French) 1983. CODEN: IJCMDW. ISSN: 0142-5463. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 4 The effect of UV-A filters, 2-hydroxy-4-methoxybenzophenone [131-57-7], 2-(2-hydroxy-5-methylphenyl)-2H-benzotriazole [2440-22-4], di-Na 4,4'-distyryl-2,2'-diphenyldisulfonate [27344-41-8], 4-tert-butyl-4'-methoxydibenzoylmethane [70356-09-1], and 4-isopropyldibenzoylmethane [63250-25-9] on the phototoxicity of bergapten [484-20-8] was evaluated. The dibenzoylmethane derivs. inhibited the toxicity to a greater extent than the other filters. The effect was greater when these compds. were administered with either bergamot oil or with a perfume than when administered in an alc. soln. The results confirm the conclusions of a recent study that not only the phototoxicity but also the carcinogenic effect of bergapten can be decreased by UV-A filters. .
