POSITRON EMISSION TOMOGRAPHY IN DRUG-EVALUATION - INFLUENCE OF 3 DIFFERENT CATECHOL-O-METHYLTRANSFERASE INHIBITORS ON METABOLISM OF [NCA] 6-[F-18]FLUORO-L-DOPA IN RHESUS-MONKEY
I. Gunther et al., POSITRON EMISSION TOMOGRAPHY IN DRUG-EVALUATION - INFLUENCE OF 3 DIFFERENT CATECHOL-O-METHYLTRANSFERASE INHIBITORS ON METABOLISM OF [NCA] 6-[F-18]FLUORO-L-DOPA IN RHESUS-MONKEY, Nuclear medicine and biology, 22(7), 1995, pp. 921-927
We compared the influence of three different catechol-O-methyltransfer
ase (COMT) inhibitors (CGP 28014, OR-611 and Ro 40-7592) on the metabo
lism of no-carrier-added (NCA) 6-[F-18]fluoro-L-dopa (6-FDOPA) in one
Rhesus monkey. All three COMT inhibitors improved 6-FDOPA availability
in plasma, increased the specific uptake in the brain and thus improv
ed 6-FDOPA uptake measurements using positron emission tomography (PET
). Best results were obtained with Ro 40-7592.
