C. Meier et al., Synthesis, hydrolysis and anti-EBV activity of a series of 3 '-modified cycloSal-BVDUMP pronucleotides, NUCLEOS NUC, 20(4-7), 2001, pp. 307-314
A series of cycloSal-BVDUMP phosphate triesters has been prepared. The prot
otype compound was 3-methyl-cycloSal-BVDUMP 2. Furthermore, a series of 3'-
O-acyl-modified derivatives having carboxylic acids with different lipophil
icity or a L-configurated alpha -amino acid (phenylalanine) was prepared. T
he hydrolysis properties in phosphate buffer PBS as well as in PBS containi
ng pig liver esterase (PLE) will be described. Finally, the biological acti
vity against EBV has been determined.
