The compounds of formula (I) wherein X represents a bond or NH—CH(C═O)—(CH2)3+n—NH—R5, n represents 0, 1 or 2, R1, R4 and R5—independently from each other—represent hydrogen, possibly substituted C1-C6-alkyl, amidino or tetra-C1-C6-alkylamidinium, R2 represents hydrogen or possibly substituted C1-C6-alkyl or R1 and R2 together with the residue to which they are bound represent a 5- to 7-membered, saturated ring, R3 represents C1-C12-alkoxy, C1-C12-alkylamino, possibly substituted aryl-C1-C6-alkylamino, possibly substituted heteroaryl-C1-C6-alkylamino, possibly substituted aryl-C1-C6-alkoxy or possibly substituted heteroaryl-C1-C6-alkoxy, and R6 represents hydrogen or, when n is 1, also amino or together with R1 and the residue to which R6 and R1 are bound a 5- to 7-membered, saturated ring, as well as their physiologically acceptable salts are new. They can be manufactured according to common methods and processed to topically applicable compositions that are appropriate for treating mimic and age-related wrinkles in human skin.
