Abstract: | The synthesis and properties of oligodeoxynucleotides (ODNs) containing 2′-O-(trifluoromethyl)adenosine (2) are described. 2′-O-(Trifluoromethyl)adenosine (2) or N6-(benzoyl)-2′-O-(trifluoromethyl)adenosine (6) was obtained in 22 or 32% yield by treating 2′-O-[(methylthio) thiocarbonyl]-3′,5′-O-(1,1,3,3-tetraisopropyldisiloxane- 1,3-diyl)(TIPDS)adenosine (4) or N6,N6-(dibenzoyl)-2′-O-[(methylthio)thiocarbonyl]-3′,5′-O-(TIPDS)- adenosine (5), respectively, with pyridinium poly-(hydrogen fluoride) in the presence of 1,3-dibromo- 5,5-dimethylhydantoin. Nucleoside 2 was incorporated into DNA hexadecamers. ODNs that contained 2 reduced the thermal stability of duplexes with their complementary DNAs but increased the thermal stability of duplexes with their complementary RNAs. Furthermore, ODNs containing 2 were slightly more resistant to snake venom phosphodiesterase than an unmodified ODN. |
