L. Denapoli et al., SYNTHESIS OF THYMIDINE DIMERS CONTAINING A NEW INTERNUCLEOSIDIC AMIDELINKAGE AND THEIR INCORPORATION INTO OLIGODEOXYRIBONUCLEOTIDES, Bioorganic & medicinal chemistry letters, 5(15), 1995, pp. 1647-1652
The synthesis of thymidine dimers 5a,b containing a chiral carbon in t
he propionamide internucleosidic linkage is described. These new epime
ric dimers were incorporated in oligodeoxyribonucleotides and the melt
ing temperature (Tm) with complementary DNA and RNA as well as the res
istence of the single strand against exonuclease were determined.
