Abstract: A hexpolyamide/seryl-histidine dipeptide conjugate DNA cleavage agent was synthesized and its structure was elucidated by NMR and ESIMS/MS methods. Complete assignment of 1H and 13C NMR chemical shifts of the compound was obtained using 2D NMR techniques, including 1H-1H COSY, HSQC and HMBC. The MS/MS fragmentation pathways of the polyamide/peptide conjugate are also discussed.

Key words: NMR, chemical shift, ESI-MS/MS, hexpolyamide, seryl-histidine dipeptide, conjugate
