Synthesis and properties of novel acyclic nucleotides.
Acyclic adenosine and thymidine analogs derived from L- and D-threonie were synthesised and incorporated into oligonucleotides by automated protocols using a standard phosphoramidite method. UV melting experiments with thus obtained oligonucleotides showed that incorporation of those acyclic nucleosides did not destabilize the hybrid duplexes and that the stabilities of them are influenced by the stereochemical structures of acyclic analogs. Modification of 3'-end of oligonucleotide with acyclic analogs protected the oligonucleotide against 3'-exonuclease.
