New peptide mimetics for the treatment of bone metabolic disorders, methods for their production, and drugs containing these compounds.

摘要

The present invention is directed to compounds of general formula (I) wherein R1, R2, R3 and X may be the same or different, and wherein R1, R2 represent hydrogen, an amino acid, peptidyl, alkyl or aryl residue; R3 represents hydroxy, lower alkoxy, or an -NR31R32 residue where R31, R32 and represent idependently hydrogen, an aminoacid, peptidyl, alkyl or aryl residue; X represents an amino acid or a peptide; R4 represents hydrogen, hydroxy, amino or C1-C4-alkyl; m represents a number between 0 and 5; R5 represents an optionally substituted saturated or unsaturated mono- or bicyclic moiety which may contain one or more heteroatoms, a C1 -C11 alkyl group which may have substitutions or intermittent heteroatoms. their tautomers, optical isomers, pharmaceutically acceptable salts and prodrugsas well as their production and their use as medicaments.
