RESUMO
The synthesis, hybridization properties and antisense activities of oligodeoxynucleotides (ODNs) containing 7-(1-propynyl)-7-deaza-2'-deoxyguanosine (pdG) and 7-(1-propynyl)-7-deaza-2'-deoxyadenosine (pdA) are described. The suitably protected nucleosides were synthesized and incorporated into ODNs. Thermal denaturation (Tm) of these ODNs hybridized to RNA demonstrates an increased stability relative to 7-unsubstituted deazapurine and unmodified ODN controls. Antisense inhibition by these ODNs was determined in a controlled microinjection assay and the results demonstrate that an ODN containing pdG is approximately 6 times more active than the unmodified ODN. 7-Propyne-7-deaza-2'-deoxyguanosine is a promising lead analog for the development of antisense ODNs with increased potency.
