Pharmacokinetics, tissue distribution, excretion, and metabolism of a novel antitumor agent, gambogenic acid, in rats

The plasma pharmacokinetics, tissue distribution, excretion, and metabolism of gambogenic acid (GNA), potential antitumor candidate, were investigated in rats. GNA showed linear pharmacokinetic characteristics in rats within the test dose (1, 2, and 4 mg/kg). The t1/2β was 40.38-41.16 min. GNA showe...

Sumario:The plasma pharmacokinetics, tissue distribution, excretion, and metabolism of gambogenic acid (GNA), potential antitumor candidate, were investigated in rats. GNA showed linear pharmacokinetic characteristics in rats within the test dose (1, 2, and 4 mg/kg). The t1/2β was 40.38-41.16 min. GNA showed an extensive distribution into multiple tissues, and the bile excretion is the major pathway of excretion, accounting for 52.12 %. About 40 % of GNA might undergo metabolism in vivo and the main phase I metabolites of GNA may be 10-hydroxygambogenic acid and 9,10-epoxygambogenic acid.
