two‐photon turn‐on fluorescent probe NHU was synthesized to optically detect tyrosinase activity in vitro and in melanoma cells. NHU is composed of a 4‐aminophenol moiety and a naphthylamine unit, both of which are connected through a urea linkage. Upon exposure to tyrosinase, the 4‐aminophenol site is gradually oxidized to the corresponding orthoquinone, ultimately releasing the highly fluorescent product
AAN有效传感器:合成双光子荧光探针NHU可以光学检测体外和黑色素瘤细胞中的酪氨酸酶活性。NHU由4-氨基苯酚部分和萘胺单元组成,两者均通过脲键连接。暴露于酪氨酸酶后,4-氨基苯酚位点逐渐被氧化为相应的邻苯二酚,最终释放出高荧光产物6-酰基-N-甲基-2-萘胺(AAN)。
