Claim:
Compounds of the general formulae (1) or (2) A-B-D-B′-A′ (1) or A-B-D-E (2), wherein A and A′ may be identical or different and are the residue wherein X is selected from the group consisting of S, O, CH 2 , CH 2 CH 2 , CH 2 O and CH 2 NH, and Y is selected from the group consisting of H and CN, and * designates a chiral carbon atom in the S-, or L-configuration; B and B′ may be identical or different and are residues selected from the group consisting of optionally containing O, S or N unsubstituted or substituted, unbranched or branched alkylene residue, cycloalkylene residue, aralkylene residue, heterocycloalkylene residue, heteroarylalkylene residue, arylamidoalkylene residue, heteroarylamidoalkylene residue, unsubstituted or mono- or poly-substituted arylene residue and heteroarylene residue having one or more five-, six- or seven-membered ring(s); D is selected from the group consisting of —S—S— and —Se—Se—; and E is selected from the group consisting of —CH 2 —CH(NH 2 )—R 9 and —CH 2 —*CH(NH 2 )—R 9 , respectively wherein R 9 is a residue selected from the group consisting of optionally containing O, N or S unsubstituted or substituted, unbranched or branched alkyl residue, cycloalkyl residue, aralkyl residue, heterocycloalkyl residue, heteroarylalkyl residue, arylamidoalkyl residue, heteroarylamidoalkyl residue, unsubstituted or mono- or polysubstituted aryl residue or heteroaryl residue having one or more five-, six- or seven-membered ring(s) and * designates a chiral carbon atom in the S-, or L-configuration; or the acid addition salts thereof with organic and/or inorganic acids.
