title: Solid-phase synthesis of cyclic peptide-DNA hybrids.
abstract: [reaction: see text] A methodology for preparing cyclic peptide-DNA hybrids on controlled pore glass in high yield is reported. This methodology employs Fmoc/Alloc-protected amino acid and nucleoside phosphoramidites on an omega-hydroxylauric acid-derivatized support and is suitable for library synthesis. A cyclic hybrid of the sequence Glu-Leu-TT-DP-Lys, where Glu and Lys are linked and T denotes a 5'-amino-5'-deoxynucleotide, exhibited high resistance to exo- and endonucleases.
