The present invention relates to deuterated compounds according to Formula I-A, Formula II-A, Formula II-D, and Formula III-A. These compounds can be used as PET imaging agents for evaluating Parkinson's Disease, Alzheimer Disease, and for determining specific serotonin reuptake inhibitor (SSRIi) activity for treatment of depression. The present invention also relates to pharmaceutical compositions comprising a pharmaceutical acceptable carrier and a compound of Formula I-A, Formulae II-A, Formula II-D, or Formula III-A, or a pharmaceutically acceptable salt thereof.
A series of compounds in the 4-fluoroalkyl-3-halophenyl nortropanes and 4-haloethenylphenyl tropane families are described as diagnostic and therapeutic agents for diseases associated with serotonin transporter dysfunction. These compounds bind to serotonin transporter protein with high affinity and selectivity. The invention provides methods of synthesis which incorporate radioisotopic halogens at a last step which permit high radiochemical yield and maximum usable product life. The radiolabeled compounds of the invention are useful as imaging agents for visualizing the location and density of serotonin transporter by PET and SPECT imaging.
本研究描述了一系列 4-氟烷基-3-卤代苯基去甲托烷和 4-卤代乙烯基苯基托烷家族的化合物,这些化合物可作为诊断和治疗与血清素转运体功能障碍有关的疾病的药物。这些化合物与血清素转运体蛋白的结合具有很高的亲和力和选择性。本发明提供了在最后一步加入放射性同位素卤素的合成方法,这种方法可以获得较高的放射化学收率和最长的产品使用寿命。本发明的放射性标记化合物可用作成像剂,通过 PET 和 SPECT 成像观察血清素转运体的位置和密度。
