[1] INHIBITORY EFFECTS OF COMMONLY USED HERBAL EXTRACTS ON UDP-GLUCURONOSYLTRANSFERASE 1A4, 1A6, AND 1A9 ENZYME ACTIVITIES.
MOHAMED,MOHAMED-ESLAM F.;FRYE,REGINALD F.
DRUG METAB DISPOS 2011 Vol.39(9),1522-8  $59749 [Full]

Part Used : ใบ
Activity : HEPATIC UDP GLUCORONOSYLTRANSFERASE ACTIVITY DECREASE
Solvent/Active Compound : Methanol, catechin epigallocatechin gallate (EGCG)
Type of experiment : in vitro
Type of animal : -
Type of study : -
N(Total) : -
N(Treatment) : -
Sex : -
Age : -
Route : -
Dose/Conc.(herb) : Dose in 53 L**
Duration : -
Type of interaction : Pharmacokinetics
Interaction with drug : Mycophenolic acid*/Mycophenolate/MMF/MPA/Mofetil
Dose/Conc.(drug) : 240 micromolar
Result : Negative
Remark : Results: data points did not fit the IC50 curve.
Note : Type of experiment: *Human liver microsomal (HLM) **Working solutions were freshly prepared so that final herbal concentrations in screening incubations would represent the recommended daily intake of each extract in 53, 5.3, and 0.53 liters. Each herbal extract was coincubated at three concentrations with trifluoperazine (for UGT1A4), serotonin (for UGT1A6), and mycophenolic acid (for UGT1A9) and human liver microsome. Formation of trifluoperezine glucoronide, serotonin glucuronide, and mycophenolic acid beta-D- glucoronide were used as index reactions for activity of UGT1A4, UGT1A6, and UGT1A9 enzyme activities, respectively.
