The present invention relates to a compound which is a novel two-photon absorbing fluorescent substance, a production method for the compound, a fluorescence sensor and molecular probe able to sense various substrates or enzyme activity or the like using the same, and a method of sensing enzyme activity or the like using the same. More specifically, the present invention relates to a novel two-photon absorbing fluorescent substance which has the high photo-stability and large two-photon absorption cross-section value of acedan which is a two-photon absorbing fluorescent substance, and has the high fluorescence efficiency of coumarin which is a one-photon absorbing fluorescent substance, while exhibiting absorption and emission characteristics at a longer wavelength than existing acedan and coumarin and so being advantageous in in-vivo imaging. The compound according to the present invention can be used as a fluorescence sensor which is highly sensitive and selective for various substrates, and more particularly, can be used in the study and treatment of diseases in which MAO enzymes are involved such as mood disorders using MAO enzyme activity and inhibitor screening.
本发明涉及一种新型的双光子吸收荧光物质,以及该化合物的生产方法、利用该化合物能够感知各种底物或酶活性的荧光传感器和分子探针,以及利用该化合物进行酶活性感知等的方法。更具体地,本发明涉及一种新型的双光子吸收荧光物质,具有高光稳定性和大的双光子吸收截面值,类似于双光子吸收荧光物质acedan,同时具有类似于单光子吸收荧光物质coumarin的高荧光效率,且在吸收和发射特性上比现有的acedan和coumarin具有更长的波长,因此在体内成像方面具有优势。根据本发明的化合物可用作高灵敏度和选择性的各种底物的荧光传感器,特别是可用于研究和治疗MAO酶参与的情绪障碍等疾病,利用MAO酶活性和抑制剂筛选。
