2'-Chloro-2'-deoxyadenosine triphosphate (cladribine), a purine nucleotide analog and potent antileukemic agent, was enzymatically incorporated into 98-base oligomers in place of dATP to investigate the molecular consequences of 2-chloroadenine (CIAde) in DNA. We have used the resultant oligomers as templates for

Cladribine (2-chloro-2'-deoxyadenosine) was synthesized using intact cells of the recombinant Escherichia coli strain producing Geobacillus stearothermophilus B-2194 thermostable purine-nucleoside phosphorylase II (EC 2.4.2.1). Use of the cells containing this thermostable enzyme allowed the process to be conducted at a temperature

Multiple lines of investigations have explored the role of cyclooxygenases (COX) in epilepsy and related neuropsychiatric disorders. Cyclooxygenase particularly, COX-2 expression was found to increase in brain during seizure paradigms. The present study was carried out to investigate the effect

Analytical biochemistry, 201(2), 277-281 (1992-03-01)
By utilization of polymerase chain reaction techniques, single-stranded DNA of defined length and sequence containing a purine analog, 2-chloroadenine, in place of adenine was synthesized. This was accomplished by a combination of standard polymerase chain amplification reactions with Thermus aquaticus
