    Area of Science:

    • Pharmacology
    • Neuroscience
    • Oncology

    Background:

    • Deoxycoformycin (DCF) is an adenosine deaminase (ADA) inhibitor.
    • Neurological toxicity is a known complication of DCF treatment.
    • Understanding drug distribution in the central nervous system is crucial.

    Purpose of the Study:

    • To investigate the pharmacokinetics of DCF in cerebrospinal fluid (CSF) and plasma.
    • To monitor the accumulation of adenosine and deoxyadenosine metabolites.
    • To explore the neuropharmacological effects of these metabolites.

    Main Methods:

    • Pharmacokinetic study in a T-cell leukemia patient with an Ommaya reservoir.
    • Measurement of DCF levels in plasma and CSF.
    • Monitoring of adenosine and deoxyadenosine concentrations in plasma, CSF, and urine.

    Main Results:

    • DCF penetrates the CSF, achieving levels up to 10% of concurrent plasma concentrations.
    • Accumulation of adenosine and deoxyadenosine was observed in plasma, CSF, and urine.
    • Correlation between metabolite levels and potential neurotoxicity was investigated.

    Conclusions:

    • DCF achieves measurable concentrations in the cerebrospinal fluid.
    • Metabolite accumulation may contribute to the observed neurological toxicity of DCF.
    • Further research is warranted to elucidate the neuropharmacological impact of these metabolites.
