The amides of the acid - methoxycinnamic urocanic acid and of the products as sunscreens, 1995, dermo - and pharmaceutical compositions containing them and applications thereof

摘要

Of the amide derivatives is obtained by reaction between the amine derivatives of linear, cyclic structure branched or amino - acid or peptide and the acid - methoxycinnamic or urocanic acid have been prepared. These compounds are specific recommended as sunscreens, in the region of 310nm and avoiding the phenomenons erythematosus during the exposure to sun. The structure of the amide is in favour of an increase in the chemical stability of these filters with respect to the esters are currently used and the condensation of the chromophores is of the amino acid - sulfurs was completed in order to improve their thereof to the skin. These products are recommended as active principles of preparations dermo - pharmaceutical and cosmetological disorders.
