N. Mignet et al., THE PRO-OLIGONUCLEOTIDE APPROACH .5. INFLUENCE OF THE PHOSPHORUS ATOMENVIRONMENT ON THE HYDROLYSIS OF ENZYMOLABILE DINUCLEOSIDE PHOSPHOTRIESTERS, Bioorganic & medicinal chemistry letters, 7(7), 1997, pp. 851-854
Six dithymidine phosphotriester analogs bearing an enzymolabile phosph
ate proctecting group were synthesized in order to select the most app
ropriate model for the prooligonucleotide approach. Series (1) under b
ar and (3) under bar were chosen on the basis of their stability in cu
lture medium and their capacity, when incubated in total cell extract,
to deliver selectively dithymidine phosphodiester and phosphorothioat
e diester respectively. (C) 1997 Elsevier Science Ltd.
