ACTIVE MOIETY
We also calculated the area under the time-activity curve from 0 to 120 minutes to compare specific organ uptake of (11C)-(R)-PK 11195 to that reported using (11C)PBR28. Using (11C)-(R)-PK 11195, pre-blockade with nonradioactive PBR28 decreased the area under the curve by only 31%, 14%, and 30% in lung, brain, and kidney, respectively. Using (11C)PBR28, pharmacological blockade was previously reported to decreased the area under the curve by 70%, 42%, and 50% in lung, brain, and kidney, respectively (Imaizumi et al., 2008). Whole body imaging with the 11C-labeled radioligands showed that (11C)PBR28 detects non-binding in all five target organs with high densities of TSPO (lung, heart, brain, kidney, and spleen).
