Related Catalog
In Vivo When the animals are pretreated with high doses of 450191S (200 or 600 mg/kg for 5 or 3 days, respectively) to induce hepatic drug-metabolizing enzymes, plasma concentrations of the metabolites after oral administration of a dose of 200 mg/kg of 450191S decrease markedly depending on the induced enzyme activity. Pretreatment of rats with phenobarbital also causes decreased plasma levels of metabolites, which are almost the same as those in 450191S-pretreatment. On the other hand, administration of beta-naphthoflavone to rats leads to higher plasma levels of metabolites, and slower elimination compared with those in the control and 450191S or Phenobarbital pretreated rats. 450191S is demonstrated to stimulate the hepatic drug-metabolizing enzymes in rats, mice and dogs, which is accompanied by a marked reduction in the pharmacological activity of pentobarbital in rats. The induction of hepatic enzyme activities by 450191S is detected only when the plasma concentrations of its metabolites are very high[1].
Animal Admin Mice[1] Adult male rats of the Jcl Sprague-Dawley strain, 7-8 weeks old, are used for the experiments. The animals are kept in an air-conditioned room (25±1°C, 50-60% humidity) lighted 12 hr a day (8:00-20:00) and maintain on com mercial rat chow and water ad libitum. 450191S is dissolved in 5% (w/v) arabic gum at 20 or 60 mg/mL, and the resulting solution is administered orally to rats at 1.0 mL/100 g body weight for 3-5 days. Typical inducers, phenobarbital (in physiological saline) and beta-naphthoflavone (in sesame oil), are administered intraperitoneally at a dose of 40 mg/kg, once daily for 3 days. The animals are fasted for 24 hr after the last adminis tration of 450191S or inducers, and then the test solution of 450191S (20 mg/mL of 5% arabic gum) is given orally to rats at a dose of 200 mg/kg. Heparinized blood samples are obtained from the abdominal aorta under ether anesthesia and centrifuged immediately to obtain plasma samples using an Eppendorf centrifuge Type 5414S.
