C. Switzer et al., SYNTHESIS AND CHARACTERIZATION OF AN OLIGONUCLEOTIDE CONTAINING THE BIFURCATED NUCLEOBASE OMEGA-ADENYLPROPYL URACIL, Bioorganic & medicinal chemistry letters, 6(7), 1996, pp. 815-818
A novel bifurcated nucleoside that bears an adenine group trimethylene
linked to the 5-position of uracil, 5-(omega-adenylpropyI)-2'-deoxyur
idine, has been synthesized and incorporated into a DNA dodecamer. Thi
s nucleoside is designed to both intercalate and hydrogen bond when in
corporated into an oligonucleotide helix. Initial results of its influ
ence on helix properties are reported. Copyright (C) 1996 Elsevier Sci
