Physiologic model for the pharmacokinetics of 2′deoxycoformycin in normal and leukemic mice
- Biology, MedicineJournal of Pharmacokinetics and Biopharmaceutics
- 2005
A flow-limited physiologic mathematical model has been developed to describe the time course of 2′deoxycoformycin concentrations in the plasma and tissues of mice following iv and ip doses and has been used to predict pharmacokinetic behaviour of2′dCF in both normal and leukemic mice.

F-ara-ATP concentrations were three times higher in bone marrow cells from patients with lymphomatous bone marrow involvement than from those without evidence of marrow disease and DNA-synthetic capacity of leukemic cells was inversely related to the associated F-ara.

The use of ADA inhibitors has helped enormously in understanding the mechanism of action of adenosine metabolites and analogs whose catabolism was heretofore neglected with respect to their specificities of action.
Clinical pharmacology of arabinofuranosyladenine in combination with deoxycoformycin
- MedicineCancer Chemotherapy and Pharmacology
- 2004
Five courses of arabinofuranosyladenine (ara-A) and deoxycoformycin (DCF) to two patients and the effects of DCF on the pharmacokinetics of ara-A were administered and abrupt declines in peripheral blast counts were observed in each patient.
In vivo toxicity to lymphoid tissue by 2′-Deoxycoformycin
- Biology, MedicineCancer Chemotherapy and Pharmacology
- 2004
No toxicity to tissues other than the lymphoid system was observed, which is consistent with the hypothesis that 2′-deoxycoformycin offers a new and selective approach to the treatment of lymphoid malignancies.

Results indicate that 2-substituted adenosine derivatives, likeadenosine, produce inhibition of transmission by acting on a presynaptic site which can be blocked by theophylline.

DAPdR exerts its toxicity on L1210 cells as a prodrug of deoxyguanosine as a result of concentration-dependent decrease in DNA synthesis and ribonucleotide reductase activity.

Results suggest that the equal toxicity of the two regimens of F-ara-A may be attributed to the similar extent of inhibition of host-tissue DNA synthesis evoked by each, which was responsible for its superior therapeutic activity.

Patients with chronic lymphocytic leukemia receiving weekly low doses of the drug demonstrated minimal toxicity and some efficacy, and the chemotherapeutic potential o 2'-deoxycoformycin, as either a single agent or in combination with Ara-A, merits further exploration.

Mice treated simultaneously with 1-β-d-arabinofuranosylcytosine (ara-C) and 6-thioguanine (6-TG) were protected from the lethal effects of 6-TG, and DNA synthesis in mouse bone marrow and L1210 cells treated in vivo with ara-C was depressed to less than 1% of control and did not begin to recover until almost 16 hr.
