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.
