The present invention describes 7-aminocoumarin dyes that are substituted one or more times at the 3-, 6- and/or 8-positions by a sulfonic acid or a salt of a sulfonic acid, said dyes being useful as fluorescent probes or in the preparation of enzyme substrates, caged probes, or adducts with reducing sugars. The dyes of the invention optionally possess a reactive group useful for preparing fluorescent conjugates, which conjugates and methods for their preparation are described herein.
本发明描述了在3-、6-和/或8-位置被磺酸或磺酸盐取代一次或多次的7-氨基香豆素染料,该染料可用作荧光探针或用于酶底物、被笼罩的探针或与还原糖形成加合物的制备中。本发明的染料可以选择性地具有用于制备荧光共轭物的反应基团,本发明描述了这些共轭物及其制备方法。
