Simple firefly luciferin analogs emitting blue, green, and red light were developed. The longest emission maximum was observed at 675 nm, which belongs to the NIR biological window (650–900 nm), useful for deep site bioimaging of living animals. The analogs showed a slow rise of emission intensity compared with the rapid emission of natural luciferin. The light emission of the adenylated analogs was strongly
开发了发出蓝,绿和红光的简单萤火虫萤光素类似物。在675 nm处观察到最长的最大发射,属于NIR生物窗口(650-900 nm),可用于活体动物的深部生物成像。与天然荧光素的快速发射相比,类似物显示出发射强度的缓慢上升。与类似物本身相比,腺苷酸化类似物的发光大大增强。
