    99mTc- and Re-labeled 6-dialkylamino-2-naphthylethylidene derivatives as imaging probes for β-amyloid plaques
    摘要:
    Based on the conjugate strategy, two neutral Tc-99m labeled 2-(1-(6-(dialkylamino)naphthalen-2-yl) ethylidene) malononitrile (DDNP) and 1-(6-(dialkylamino) naphthalen-2-yl) ethanone (ENE) derivatives, and their corresponding rhenium complexes were synthesized. In vitro fluorescent staining indicated that the corresponding rhenium derivatives selectively stained the beta-amyloid (A beta) plaques in the brain sections of AD model mice with low background. Compared with FDDNP and FENE, the affinities of the corresponding rhenium derivatives to A beta aggregates decreased about 10-14-fold. In vivo biodistribution experiments in normal mice showed that Tc-99m-MAMA-ENE displayed medium initial brain uptake (0.65 % ID/g at 2 min) with a reasonable washout from the brain (0.19 % ID/g at 2 h) while (99mTc)-MAMA-DDNP showed a low brain uptake (0.28 % ID/g at 2 min). Further optimize these Tc-99m-labeled tracers in order to improve their binding affinities to A beta plaques and diffusion through the blood brain barrier may generate useful imaging agents for SPECT.
