| description | This study aimed to evaluate (
)-[
F]YH134 as a novel PET tracer for imaging monoacylglycerol lipase (MAGL). Considering the ubiquitous expression of MAGL throughout the whole body, the impact of various MAGL inhibitors on (
)-[
F]YH134 brain uptake and its application in brain-periphery crosstalk were explored.
MAGL knockout and wild-type mice were used to evaluate (
)-[
F]YH134 in in vitro autoradiography and PET experiments. To explore the impact of peripheral MAGL occupancy on (
)-[
F]YH134 brain uptake, PET kinetics with an arterial input function were studied in male Wistar rats under baseline and blocking conditions.
In in vitro autoradiography, (
)-[
F]YH134 revealed a heterogeneous distribution pattern with high binding to MAGL-rich brain regions in wild-type mouse brain slices, whereas the radioactive signal was negligible in MAGL knockout mouse brain slices. The in vivo brain PET images of (
)-[
F]YH134 in wild-type and MAGL knockout mice demonstrated its high specificity and selectivity in mouse brain. A Logan plot with plasma input function was applied to estimate the distribution volume (
) of (
)-[
F]YH134.
was significantly reduced by a brain-penetrant MAGL inhibitor but was unchanged by a peripherally restricted MAGL inhibitor. The MAGL target occupancy in the periphery was estimated using (
)-[
F]YH134 PET imaging data from the brain.
(
)-[
F]YH134 is a highly specific and selective PET tracer with favorable kinetic properties for imaging MAGL in rodent brain. Our results showed that blocking of the peripheral target influences brain uptake but not the
of (
)-[
F]YH134. (

F]YH134 can be used for estimating the dose of MAGL inhibitor at half-maximal peripheral target occupancy. |
