摘要:
We synthesized pyrrolidino-C-nucleosides, incorporated them into oligodeoxynucleotides and investigated their pairing properties. The thermal duplex and triplex stabilities were measured. While triplex formation is destabilized in the case of pyrrolidino-pseudo-U and -T, pyrrolidino-pseudo-iso-C leads to an increase of the T-m value for third strand dissociation. Duplexes Lire destabilized with all pyrrolidino-C-nucleosides.
