[18F]MNI-1054

[18F]MNI-1054 is a small molecule, enzyme-targeted radiopharmaceutical developed as a positron emission tomography (PET) imaging agent. It acts as a marker for lysine-specific histone demethylase 1A (KDM1A/LSD1), enabling the visualization and quantification of this enzyme in the brain. The compound is used primarily in research settings to assess KDM1A occupancy, particularly in studies evaluating the pharmacodynamics of KDM1A inhibitors such as TAK-418. Its mechanism involves enhancing PET imaging signals by binding specifically to LSD1/KDM1A, facilitating non-invasive measurement of target engagement in clinical trials[1][2][3][5].
