New effectors of dipeptidyl peptidase IV for topical use

Abstract

The invention relates to compounds for topically influencing the activity of dipeptidyl peptidase of the general formula 1 wherein A is an amino acid having at least one functional group in the side chain; B is a chemical compound covalently bound to a functional group of the side chain of A, chosen from the group consisting of (a) oligopeptides having a chain length of up to 20 amino acids, (b) homopolymers of glycine consisting of up to 6 glycine monomers, and (c) polyethylene glycols having molar masses of up to 20 000 g/mol; and C is a group amide-bonded to A chosen from the group consisting of thiazolidine, pyrrolidine, cyanopyrrolidine, hydroxyproline, dehydroproline or piperidine. The invention further relates to the use of said compounds for targeted intervention in local immunological processes (chemotaxis, inflammatory processes, autoimmune diseases), as well as effective and targeted treatment of pathophysiological and physiological processes related thereto (psoriasis, periodontitis, arthritis, allergies, inflammation), inter alia.
