In this research, a series of napthalimide-based small-molecule fluorescent probes（1a-1f） for α1-ARs, including two parts, a pharmacophore（quinazoline and phenylpiperazine） for α1-AR recognition and a fluorophore（naphthalimide） for visualization, were designed and synthesized successfully. These compounds display excellent fluorescence property and high affinity to receptors,which were used successfully for in vitro visualization of α1-adrenoceptors.展开更多
