The use of photoresponsive ligands to optically control proteins of interest, known as photopharmacology, is a powerful technique for elucidating cellular function in living cells and animals with a high spatiotemporal resolution. The adenosine A 2A receptor (A 2A R) is a G protein-coupled receptor that is expressed in various tissues; its dysregulation is implicated in severe diseases such as insomnia and Parkinson's disease. A detailed elucidation of the physiological function of A 2A R is, therefore, highly desirable. In the present study, we developed two photoswitchable ligands, photoAd(blue) and photoAd(vio), that target A 2A R. Using photoAd(vio), we successfully demonstrated the selective activation of A 2A R in living cells by violet-light irradiation with high spatiotemporal resolution. |
