Research Abstract |
We investigated the feasibility of our originally established brain-targeting (BT) peptide for novel ligand development of brain PET imaging. We successfully demonstrated the potential of [11C]MQNB-BT peptide conjugate in brain-penetrating activity, whereas [11C]MQNB itself has no such activity. Quantitative analysis indicated that [11C]MQNB-BT peptide conjugate had about 10% brain-penetrating activity of [11C]NMPB, which is permeable to blood-brain barrier. These results suggested that BT peptide has a potential of a DDS carrier for brain function imaging tools.
