Solid-phase synthesis of symmetrical 3,6-bispeptide-acridone conjugates.
[reaction: see text] A novel high-yielding method for the solid-phase synthesis of 3,6-bispeptide-acridone conjugates is reported. It involves initial coupling of bifunctionalized acridone to a resin-bound peptide followed by an on-bead site-site reaction to couple the second peptide. This method leads to clean symmetrical bispeptide derivatives and appears to be general. This strategy will enable the generation of a library of 3,6-bispeptide-acridones to be screened for selective binding to telomeric G-quadruplex DNA.
