Provided is a method for preparing a novel benzocoumarin-based two-photon absorbing fluorescent dye, such as a pyridinium-benzocoumarin (Py
+
BC) derivative compound and its precursor compound (pyridyl-benzocoumarin, PyBC), an aryl-benzocoumarin (ArBC) derivative compound, a benzothiazolyl-benzocoumarin (BtBC) derivative compound or a keto-benzocoumarin (KetoBC) derivative compound. The Py
+
BC derivative compound of the present invention is a two-photon absorbing near-infrared fluorescent dye, which may minimize interference of autofluorescence compared to conventional two-photon absorbing fluorescent dyes such as acedan and naphthalimide, thereby obtaining a high-definition image, and therefore is expected to be effectively used in imaging studies. In addition, when the two-photon absorbing near-infrared fluorescent dye of the present invention is used, it is expected to be suitable for high resolution imaging of deep tissue.
提供了一种制备新型苯并香豆素基双光子吸收荧光染料的方法,例如吡啶铵苯并香豆素(Py+BC)衍生物化合物及其前体化合物(吡啶基苯并香豆素,PyBC),芳基苯并香豆素(ArBC)衍生物化合物,苯并噻唑基苯并香豆素(BtBC)衍生物化合物或酮基苯并香豆素(KetoBC)衍生物化合物。本发明的Py+BC衍生物化合物是一种双光子吸收近红外荧光染料,与传统的双光子吸收荧光染料(如acedan和naphthalimide)相比,可以最小化自体荧光的干扰,从而获得高清晰度图像,因此预计可在成像研究中有效使用。此外,当使用本发明的双光子吸收近红外荧光染料时,预计适用于深层组织的高分辨率成像。
