본 발명은 신규한 코마린 유도체, 이의 제조방법 및 상기 코마린 유도체를 다수 포함하는 LED 광원에 의해 발광 가능한 다중 형광체에 관한 것이다. 본 발명에 따른 신규한 코마린 유도체 다중형광체는 512 nm 내지 590 nm의 최적 여기 파장범위를 가지므로 LED 광원에 의해 발광이 가능하므로 신호의 세기 및 안정성이 개선된 효과를 나타낸다. 또한, 공지된 코마린 형광체와 비교하여 한 분자가 다수의 형광체를 가지게 되는 바. 높은 형광 반응을 나타내며, 항체에 최소한의 형광체 분자만 결합하더라도 형광 검출이 가능한바, 코마린 형광체가 항체의 항원과 결합하는 부위에 결합될 수 있는 문제를 해결하였다. 또한, 본 발명에 따른 신규한 코마린 유도체 다중형광체는 LED 기반 진단용 미세형광정량 바이오센서로서 형광표지면역분석법(FLISA) 및 신속 형광 면역크로마토그래피법(FICT)에 적합하게 사용될 수 있는바 말라리아 등의 질환을 신속하고 정량적으로 분석할 수 있다.

The present invention relates to a novel coumarin derivative, to a method for preparing the same, and a multi-fluorescent substance that includes a plurality of the coumarin derivatives and is able to emit light using an LED light source. A novel coumarin derivative multi-fluorescent substance according to the present invention has an optimal emission wavelength band of 512 nm to 590 nm and thereby is effective in improving a signal intensity and stability since light emission using an LED light source is possible.
In addition, higher fluorescence reactivity is exhibited compared to coumarin fluorescent substances known in the related arts since one molecule has a plurality of fluorescent substances, and the problem of the coumarin fluorescent substance possibly binding to a binding site of the antigen of the antibody is solved since fluorescence detection is possible even when a minimum number of fluorescent substance molecules bind to an antibody.
Moreover, the novel coumarin derivative multi-fluorescent substance according to the present invention is suitably used in a fluorescent-linked immunosorbent assay (FLISA) and a rapid fluorescent immunochromatographic test (FICT) as an LED-based microfluorescent quantitative biosensor for diagnosis, therefore, diseases such as malaria may be rapidly and quantitatively analyzed.
