The compounds of the invention are ASEM analogs with differentortho- and para-substitutions that can be labelled with3H and/or11C to be used as PET radiotracers capable of binding to α7-nAChR both in vitro andin vivoin a subject body. The PET radiotracers thereby enable visualization and quantification of α7-nAChR in various target tissues, including monitoring the distribution of α7-nAChRs in such a target tissue. The compounds exhibit of high binding affinity and specificity towards α7-nAChR and are able to pass the blood-brain barrier (BBB).
本发明的化合物是带有不同的邻位和对位取代基的A
SEM类似物,可以用3H和/或11C标记,用作PET放射追踪剂,能够在体内和体外结合到α7-nAChR。因此,PET放射追踪剂可以在各种靶组织中可视化和量化α7-nAChR,包括监测α7-nAChR在该靶组织中的分布。这些化合物表现出对α7-nAChR的高结合亲和力和特异性,并能够穿过血脑屏障(BBB)。
