Pharmacokinetics of hydroxyurea in nude mice.

Abstract:

:Extrachromosomal DNA is the predominant form of gene amplification in human tumors. Hydroxyurea (HU) concentrations of 100-150 microM have been promising in vitro for extrachromosomal DNA elimination. The study objective was to determine the HU dose-concentration relationship in nude mice with HU doses from 0 to 200 mg/kg. For HU t1/2 determination, mice were injected with HU 100 mg/kg. A plasma concentration of 159 microM was achieved and a t1/2 of 11.3 min determined. Based on these findings, In vivo elimination studies will require frequent administration of HU to maintain plasma concentrations from 100 to 150 microM.
