The purine analog, 2-chloro-2'-deoxyadenosine triphosphate (CldATP), was incorporated enzymatically in place of dATP into the minus strand of M13mp18 duplex DNA. Its effect on protein-DNA interactions was assessed by determining the amount of DNA cleavage by type II restriction endonucleases.

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
