The tautomeric stability and vibrational IR spectrum of 2-chloroadenine were studied using density functional theory (DFT) at B3LYP/6-31G* level. The amino N(9)H tautomer of 2-chloroadenine was predicted to be most stable. A scaled quantum mechanical (SQM) force field approach was

Since the heterologous tolerance that develops after chronic morphine administration has been proposed to be an adaptive process, it follows that the time course of the change in the cellular components should coincide with the time course of the altered

EHEB cells, a continuous cell line derived from a patient with B cell chronic lymphocytic leukemia (B-CLL), synthesized, when incubated with tritiated 2-chloro-2'-deoxyadenosine (CdA), labeled mono-, di-, and triphosphate ribonucleosides at a much higher rate than CdA deoxyribonucleotides. Further analysis

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

The nucleoside analog 2-chlorodeoxyadenosine (Cladribine, CdA) is used in the treatment of patients with several hematological malignancies. After administration of CdA, the major catabolite measured in plasma and urine is 2-chloroadenine (CAde). This study was performed to determine the pharmacokinetics
