6-Chloropurine riboside is used to study the kinetics and substrate specificity of adenosine deaminase. 6-Chloropurine riboside is benzoylated to facilitate synthesis of nucleoside derivatives such as 9-(2,3-Di-deoxy-2-fluoro-β-D-threo-pentofuranosyl)adenine. 6-Chloropurine riboside, especially after phosphorylation to NMP, NDP or NTP, is used as a purine substrate analogue in studies with enzymes such as Inosine monophosphate dehydrogenase (IMPDH); bacteriophage T4 RNA-ligase (EC 6.5.1.3) and pancreatic fibonuclease A.
The NTP binding site of bacteriophage T4 RNA-ligase (EC 6.5.1.3) was studied using several ATP analogs modified in the purine moiety of the nucleotide at positions 1, 2, 6 and 8: adenosine-N'-oxide 5'-triphosphate (I), 6-chloropurine riboside 5'-triphosphate (II), 6-mercaptopurine riboside

Adenosine deaminase (ADA) was isolated from small intestine of mice and purified to utmost homogeneity. SDS-PAGE of purified ADA gave a molecular weight of 41 kDa. Western blot analyses gave a single reactive band at 41 kDa and the other

When the reaction of bovine pancreatic ribonuclease A with 6-chloropurine riboside 5'-monophosphate was carried out in the presence of several natural mononucleotides, a decrease of 25-75% was found in the amount of the reaction product derivative II (the main product
A new method to introduce a benzyl group onto the 2'-OH of purine ribonucleoside is described. Thus, 6-chloropurine 3'-O-benzoylriboside and its 5'-O-trityl congener were condensed with benzyl alcohol using the Mitsunobu reaction to give the 2'-O-benzyl derivative. The yields were
This work describes the application of thermophilic microorganisms for obtaining 6-halogenated purine nucleosides. Biosynthesis of 6-chloropurine-2'-deoxyriboside and 6-chloropurine riboside was achieved by Geobacillus stearothermophilus CECT 43 with a conversion of 90% and 68%, respectively. Furthermore, the selected microorganism was satisfactorily
