Outline of Final Research Achievements

Epigenetic modifications mediated by histone deacetylases (HDACs) play important roles in the mechanisms of different neurologic diseases and HDACIs have shown promise in therapy. However, pharmacodynamic profiles of many HDACIs in the brain remain largely unknown due to the lack of validated methods for noninvasive imaging of HDAC expression-activity. In this study, radiosynthesis of novel PET tracer of [18F]FAHA, a novel HDAC substrate and assessment the efficacy of [18F]FAHA PET imaging was performed. And also, [18F]fluoroacetate, the major radio-metabolite of [18F]FAHA was focused on for brain imaging using animal study. PET imaging with [18F]FAHA reflects the level of expression-activity of HDAC class IIa enzymes. The results suggest that the HDAC inhibitor may have efficacy, especially in the acute phase of the ischemic stroke and that the [18F]FAHA-PET and [18F]fluoroacetate-PET imaging are quite useful for providing a new therapeutic strategy in ischemic stroke.
