                                    Two polycyclic peptides have been prepared in which all four of the epsilon-nitrogens of cyclo-(Lys-Lys-Gly)2 are interconnected by intra-molecular cross-links. One of these compounds possessed (CH2)6 units between the adjacent lysyl residues and 4,4'-dimethylenebiphenyl units between the skipped lysyl residues, whilst the other contained p-xylyl units between all four of the lysyl residues.
