Abstract:
:The pharmacodynamic and pharmacokinetic properties of endpoint-attached N'alkylamine derivatives of low molecular mass heparin (LMMH), low molecular mass heparin (LMMH), low molecular mass heparin-tyramine (LMMH-tyr) and low molecular mass heparin-tyramine-fluorescein-5-isothiocyanate (LMMH-tyr-fitc) were investigated ex vivo. After intravenous bolus injection of LMMH, LMMH-tyr and LMMH-tyr-fitc (150 aXa U/kg) to Sprague-Dawley rats (n = 8), LMMH-tyr and LMMH-tyr-fitc displayed decreased clearances. The beta-half-life time of the antifactor Xa (aXa) of "endpoint-attached heparins" was significantly prolonged: LMMH-tyr (125 min), LMMH-tyr-fitc (141 min) compared to LMMH (69 min). The pharmacokinetics of LMMH-tyr-fitc were measured with reversed phase high performance liquid chromatography (RP-HPLC). It showed a decreased clearance and a prolonged half-life time (132 min). The selectively tagged LMMH-tyramine and LMMH-tyramine-fitc may be used to investigate the pharmacokinetics, plasma protein and cellular binding of low molecular mass heparins.
