Pharmacokinetics of Caffeic Acid Phenethyl Ester and Its Catechol-Ring Fluorinated Derivative Following Intravenous Administration to RatsBiopharmaceutics & Drug Disposition, Volume 30 Issue 5, Pages 221 - 228
The pharmacokinetic profiles of caffeic acid phenethyl ester (CAPE) and its catechol-ring fluorinated derivative (FCAPE) were determined in rats after intravenous administration of 5, 10 or 20 mg/kg for CAPE and 20 mg/kg for FCAPE, respectively…
The results showed that the area under the plasma concentration-time curve for CAPE treatment increased in a proportion greater than the increase in dose from 5 to 20 mg/kg of CAPE. Total body clearance values for CAPE ranged from 42.1 to 172 ml/min/kg (NCA) and decreased with the increasing dose of CAPE. Similarly, the volume of distribution values for CAPE ranged from 1555 to 5209 ml/kg, decreasing with increasing dose. The elimination half-life for CAPE ranged from 21.2 to 26.7 min and was independent of dose.
That FCAPE was distributed extensively into rat tissues and eliminated rapidly was indicated by a high value of volume of distribution and similar short elimination half-life as that of CAPE.
