Synthesis and Characterization of Environment-Sensitive Fluorescent Ligands for Human 5-HT1A Receptors with 1-Arylpiperazine Structure
摘要:
A series of "long-chain" 1-(2-methoxyphenyl)piperzine derivatives containing an environment-sensitive fluorescent moiety (4-amino-1,8-naphthalimide, 4-dimethylaminophthalimide, dansyl) was synthesized. The compounds displayed very high to moderate 5-HT1A receptor affinity and good fluorescence properties. 6-Amino-2-[5-[4-(2-methoxyphenyl)-1-piperazinyl]pentyl]-1H-benz[de]isoquinoline-1,3(2H)-dione (4) combined very high 5-HT1A receptor affinity (K-i = 0.67 nM), high fluorescence emission in CHCl3, and undetectable fluorescence emission in aqueous solution. It was evaluated for its ability to visualize 5-HT1A receptors overexpressed in CHO cells by fluorescence microscopy.
