  Synthesis and Properties of Nonpolar DNA (Arylalkyl)phosphonates

  摘要：

  The eight (arylalkyl)-modified phosphoramidites (=(arylalkyl)phosphonamidites) 1-8 (Fig. 2) were synthesized (Schemes 1-3) and incorporated at different positions into 2'-deoxyoligonucleotides. The [P(R)]and [P(S)]-diastereoisomers of the hexanucleotides 32-39 (Table 1) and of the dodecanucleotides 41-45 (Table 2) obtained were separated by means of reversed-phase HPLC. UV, CD, and fluorescence spectroscopy were used to investigate the thermal stability (T-m) and the structural changes of their DNA duplexes with 5'-d(CGCGCG)-3' and 5'-d(ATGATTGACCTG)-3', respectively. The T-m values significantly depend on the place of modification (Table 2). A dangling-end effect is observed when the [3-(anthracen-9-yl)propyl]-modified 8 is attached at the 5'-terminus (see duplex with 45c). In the case of the incorporation of aromatic moieties tethered via a methylene linker to the P-atom (benzyl- and (naphthalen-1-ylmethyl)-modified 1 and 6, resp.), the duplexes with the [P(R)]-oligonucleotides are more stable than those with the [P(S)]-isomers, whereas in the case of longer alkyl chains at the P-atom (see 2-5), the T-m values show the reverse tendency. The observed T-m differences are assigned to changes in base stacking (Figs. 6 and 7).
