摘要:
Positron-emission tomography (PET) is a noninvasive realtime functional imaging system and is expected to be useful for the development of new drug candidates in clinical trials. For its application with preformulated liposomes, we devised an optimized [F-18]-compound and developed a direct liposome modification method that we termed the "solid-phase transition method". We were successful in using 1-[F-18]fluoro-3,6-dioxatetracosane ([F-18]7a) for in vivo trafficking of liposomes. This method might be a useful tool in preclinical and clinical studies of lipidic particle-related drugs.
