ACTIVE MOIETY
INTRODUCTION: Up-regulation of the type 2 cannabinoid receptor (CB(2)R) has been reported in (neuro)inflammatory diseases. In this study, we report the preclinical evaluation of ((11)C)NE40 as positron emission tomography (PET) radioligand for visualization of the CB(2)R. RESULTS: ((11)C)NE40 shows specific CB(2)R binding in the spleen and blood of normal rats and high brain uptake in rhesus monkey. ((11)C)NE40 showed specific and reversible binding to hCB(2)R in vivo in a rat model with local hCB(2)R overexpression. CONCLUSIONS: ((11)C)NE40 shows favorable characteristics as radioligand for in vivo visualization of the CB(2)R and is a promising candidate for hCB(2)R PET imaging.
ACTIVE MOIETY
RESULTS: (11C)-NE40 showed high initial uptake in the spleen and a predominant hepatobiliary excretion. In the brain, rapid uptake and swift washout were seen. Organ absorbed doses were largest for the small intestine and liver, with 15.6 and 11.5 .MU.Gy/MBq, respectively. The mean effective dose was 3.64+/-0.81 .MU.Sv/MBq. There were no changes with aging observed. No adverse events were encountered. CONCLUSIONS: This first-in-man study of (11C)-NE40 showed an expected biodistribution compatible with lymphoid tissue uptake and appropriate fast brain kinetics in the healthy human brain, underscoring the potential of this tracer for further application in central and peripheral inflammation imaging. The effective dose is within the typical expected range for 11C ligands.
