The invention relates to a compound of formula (I)
Wherein:
B is adenine, guanine or hypoxanthine
Z is hydrogen or a negative charge
R is —[CH2CH(R1)—O]n—R2, —CH2CH2X, in which
R1 is hydrogen or (C1-C6) alkyl
R2 is hydrogen or (C1-C6) alkyl
n is a number from 1 to 6
X is OH, F, NR3R4
R3 and R4 are independently from each other hydrogen or (C1-C6) alkyl and to methods of enzymatically treating these compounds with biocatalysts having cyclic phosphodiesterase activity.
