Figure 5From: Synthesis and evaluation of [11C]MMPIP as a potential radioligand for imaging of metabotropic glutamate 7 receptor in the brain Radioactive compositions in the rat brain. TACs showed total radioactivity (filled circles), intact (open squares), and two metabolites (open triangles). The TACs in the intact and metabolites were corrected by a fitting curve obtained from metabolite fractions of the brain.Back to article page
