Article Title: Synthesis of [ 18 F]PS13 and Evaluation as a PET Radioligand for Cyclooxygenase-1 in Monkey
doi: 10.1021/acschemneuro.0c00737
Figure Lengend Snippet: PET studies of brain in monkey A with [18F]PS13 (carrier PS13:6.6 nmol/kg at baseline). Panel A: regional VT images from baseline scan (top row) and blocked scans (with PS13, 0.3 mg/kg, i.v.) (middle row), and corresponding MRI images (bottom row). Left column: coronal images; middle column: sagittal images; right column: horizontal images. Highest radioactivity uptake occurred in the prefrontal and parietal cortices. Panel B: whole brain time-activity curves at baseline and after preblock obtained with [18F]PS13. Corresponding curves obtained in a different monkey with [11C]PS13 from the study in ref 17 with a much lower PS13 carrier dose (0.19 nmol/kg at baseline) are shown for comparison.
Article Snippet: The HPLC apparatus for [ 18 F]PS13 separation comprised a pump (P4.1S; Knauer; Berlin, Germany), a UV absorbance detector (UVD2.1S; Knauer), and a radioactivity detector (flow-count; Eckert & Ziegler; Berlin, Germany).
