A kind of photoaffinity labeling double function probe molecule is provided. The probe molecule provided by the invention has strong affinity for GABAB receptors and combination capability with high selectivity. Simultaneously, it can be used under living cell level for the GABAB receptors on the membrane in labeling, tracing, and analyzing the dynamic change process of the intracellular relevant signaling proteins resulted from activation or antagonism. And it can be used for finding new target point and investigating proteomic mass spectrometry. It provides more direct and more accurate important information for the diagnosis of the disease related to GABAB receptors and for the exploiture of the corresponding therapeutic drugs.
