摘要

1. The in vitro hydrolysis of DGBA in rat blood and its in vivo metabolism and disposition in male Sprague-Dawley rats were studied. 2. DGBA (5 mM) was hydrolysed in rat blood to diethylene glycol monobutyl ether (DGBE) with a half-life of less than 3 min. 3. 14C-DGBA was rapidly absorbed from the gastrointestinal tract and eliminated predominantly in rat urine within 24 h following oral administration at 200 or 2000 mg/kg. The major urinary metabolite was 2-(2-butoxyethoxy)acetic acid. No unchanged DGBA or DGBE was detected in rat urine at either dose level. 4. No evidence was found for excretion of 2-butoxyacetic acid, which has been shown to exert haematological effects in rats.
