<p>N-Aryl-2-hydroxy alkylamides (I), their isomers, acylated derivatives and salts, their preparation, and cosmetic and pharmaceutical compositions containing them. The new compounds are of formula (I) R1 = H, halogen, CN, 1-4C alkyl, perfluoroalkyl, or -OR6; R2 = NO2, CN, halogen, -SO2R7, ; R3 = H, halogen, CN, 1-4C alkyl optionally substituted by halogen or OR6; R4 = H or 1-4C alkyl optionally substituted by halogen; R5 = 1-4C alkyl substituted by halogen or phenyl optionally substituted by halogen, CN, or NO2; R6 = H or 1-4C alkyl; R7 = H, 1-4C alkyl, or phenyl optionally substituted by halogen; Y' = OR or NRR'; R and R' = H, 1-8C alkyl optionally substituted by OH or COOR6, or R-N-R' may form a 5 or 6 membered ring Preferred compounds are those in which R1 is Cl, methyl, methoxy, or trifluoromethyl, R2 is Cl, -CO-phenyl, or -COO-ethyl, R3 is Cl, CF3, or methoxy, R4 is methyl, CF3, R5 is CF3, and Y is NH-butyl or NHCOO-propyl.</p> |
