A photosensitive azide-fluoro-dehydrocoelenterazine analog (Az-F-DCT) was synthesized, starting from 4-fluorophenylacetic acid, as a photoaffinity-labeling probe in order to analyze symplectin active site. To examine the photo-reactivity of Az-F-DCT, azide-fluoro-coelenterazine analog (Az-F-CT) was used as a potent symplectin chromophore model. Photolysis of Az-F-CT in 2,2,2-trifluoroethanol afforded
以4-氟苯基乙酸为原料,合成了光敏叠氮化物-氟-脱氢腔肠素类似物(Az-F-DCT)作为光亲和标记探针,以分析symplectin的活性位点。为了检查Az-F-DCT的光反应性,将叠氮化物-氟-腔肠素类似物(Az-F-CT)用作有效的slectlectlectin生色团模型。在2,2,2-三氟乙醇中对Az-F-CT进行光解,得到腈中间体,得到插入产物。通过光谱分析,特别是通过使用质子/氘(H / D)交换实验以及ESI-Q-TOF-MS和-MS / MS测量,证实了该产品的结构。
