摘要
A cluster of four d(TG(4)T) hexanucleotides with the 3'-ends linked together by a bunchy spacer has been synthesized and shown to form a monomolecular parallel quadruplex 5 in solution characterized by four G-quartets. H-1 NMR spectroscopy and CD thermal denaturation experiments indicate the monomolecular quadruplex (5) to be more stable than the tetramolecular counterpart [d(TG(4)T)](4). (C) 2004 Elsevier Ltd.
