The C-nucleoside2’-deoxypseudouridine, in contrast to dU, forms stable C:pseudoU-A triplets.2-Aminopurine lacks groups critical for hydrogen bonding and is a mildlyfluorescent base.
Demand for sulfur modified bases continues to expand forinvestigations of oligonucleotide structure, but primarily for cross-linkingpurposes. 6-Thio-dG, 4-Thio-dT and 4-thio-dU are very useful modifications forphoto cross-linking and photoaffinity labelling experiments. Oligos containing2-thio-dT are useful in examining protein-DNA interaction by acting asphotosensitizing probes. The thiocarbonyl group in 2-thio-dT is especiallyinteresting in that it is available to react with compounds associating with theminor groove of DNA. 2-Amino-A forms a very stable base pair with T containingthree hydrogen bonds but the stability of the base pair with 2-thio-T is greatlydiminished. Due to steric interactions between the 2-thio group of thymidine andthe 2-amino group of 2-amino-A, the base pair contains only a single hydrogenbond. Oligos containing 2-amino-dA and 2-thio-dT exhibit high affinity fornatural oligonucleotides but show little affinity for other similar oligos evenof a complementary sequence.
