are H, alkyl or alkoxyalkyl; and Z is optionally substituted aryl or heteroaryl are disclosed. Also disclosed is the use of compounds of formula I in the treatment of central nervous system diseases, in particular Parkinson's disease, alone or in combination with other agents for treating Parkinson's disease, and pharmaceutical compositions comprising them.
Novel compounds that find use as imaging agents within nuclear medicine applications (PET imaging) for imaging of cardiac innervation are disclosed. These PET based radiotracers may exhibit increased stability, decreased NE release (thereby reducing side effects), improved quantitative data, and/or high affinity for VMAT over prior radiotracers. Methods of using the compounds to image cardiac innervation are also provided. In some instances the compounds are developed by derivatizing certain compounds with
18
F in a variety of positions: aryl, alkyl, a keto, benzylic, beta-alkylethers, gamma-propylalkylethers and beta-proplylalkylethers. Alternatively or additionally, a methyl group a is added to the amine, and/or the catechol functionality is either eliminated or masked as a way of making these compounds more stable.

本研究公开了在核医学应用(PET 成像)中用作心脏神经支配成像剂的新型化合物。这些基于 PET 的放射性racer 与之前的放射性racer 相比,可表现出更高的稳定性、更少的 NE 释放(从而减少副作用)、更好的定量数据和/或对 VMAT 的高亲和力。还提供了使用这些化合物对心脏神经支配进行成像的方法。在某些情况下,这些化合物是通过在芳基、烷基、酮基、苄基、β-烷基醚、γ-丙基烷基醚和β-丙烯基烷基醚等不同位置上用 18F 对某些化合物进行衍生而得到的。另外,还可以在胺中加入甲基,和/或消除或掩盖儿茶酚官能团,使这些化合物更加稳定。
