A series of new DNA binding molecules NCD-Cn-SH (n = 3, 4, 5, and 6) is reported, which possesses the NCD (naphthyridine carbamate dimer) domain selectively binding to the G-G mismatch in the 5′-CGG-3′/5′-CGG-3′ sequence and a thiol moiety, which undergoes spontaneous dimerization to (NCD-Cn-S)2 upon oxidation under aerobic conditions. The S-S dimer (NCD-Cn-S)2 produced the 1:1 binding complex with improved thermal stability. The dimer binding to the CGG/CGG DNA showed higher positive cooperativity than the binding of monomer and previously synthesized NCTn derivative. The dimerization of NCD-Cn-SH was selectively accelerated on the CGG repeat DNA but not on the CAG repeat DNA.

New thiol-containing auxiliaries were developed for peptide ligation. They were placed at the amidyl N-atom in the second amino acid residue of a peptide fragment. With the new auxiliaries, peptide ligation could be conducted at non-Cys and non-Gly sites. Compared to other recently developed auxiliaries, an important feature of the present design was that the new auxiliaries were generally applicable and readily removable.
