Imatinib metabolism and disposition in isolated rat perfused liver
Imatinib is an orally administered tyrosine kinase inhibitor which inhibits the Bcr-Abl protein-tyrosine kinase with high selectivity. Imatinib is rapidly absorbed from the gut, after oral intake and has an almost absolute bioavailability of 98%. The metabolism of imatinib is mediated by the cytochrome P450 (CYP) isoenzymes in the liver and gut wall. CGP74588 is a major active metabolite of ima...
متن کاملStudies on alpha-adrenergic-induced respiration and glycogenolysis in perfused rat liver.
Phenylephrine (1.5 x 10(-6) M) administered to perfused livers from fed rats gave rise to a rapid, parallel increase in oxygen uptake and glucose output. The time of onset for oxygen uptake was 9.9 +/- 0.4 s following phenylephrine administration, and immediately preceded glucose output which occurred at 11.6 +/- 0.5 s. Near-maximal effects were observed 50 s following alpha-agonist treatment. ...
متن کاملThe isolated perfused rat liver.
The disposition of mefloquine has been investigated in the isolated perfused rat liver (IPRL) preparation after the administration of [C]mefloquine HCI (3.8 mg, 4 1 Ci, quinoline ring labeled). Mefloquine underwent avid hepatic uptake within 10 min of dosing. Also at this point, hepatic oxygen consumption was reduced markedly in four of the six IPRL preparations, but was restored completely by ...

Phenylephrine (1.5 X lo-‘ M) administered to perfused livers from fed rats gave rise to a rapid, parallel increase in oxygen uptake and glucose output. The time of onset for oxygen uptake was 9.9 f 0.4 s following phenylephrine administration, and immediately preceded glucose output which occurred at 11.6 k 0.5 s. Near-maximal effects were observed 50 s following aagonist treatment. Both respon...
متن کاملCo-Exposure Effects of LPS with Various Aflatoxin B1 Doses in Isolated Perfused Rat Liver Model
Background: Activation of inflammatory cells can cause more chemicals induced-hepatotoxicity. Aflatoxin B1 (AFB1) is a fungal toxin that induces acute hepatotoxicity in humans and animals. This study was conducted to examine the effect of co-exposure LPS and various aflatoxin B1 doses on the damage hepatic parameters in isolated perfused rat liver. Methods: Thirty-two male wistar rats (250-3...
