The invention provides probes with formula (I):
in which:
X1═NH, O, or S; X2═O or S; SE is a labile group, which may be eliminated under the action of a stimulus that may in particular be the presence of an enzyme, a chemical compound, or a physicochemical characteristic of the medium in which the probe is located; A is an aromatic group that, following cleavage of the C(X2)—O bond in aqueous solution, leads to the liberation of a chromophore or a fluorophore, R represents a hydrogen atom or -(L)n-GP, in which n is equal to 0 or 1, L is a linker arm, and GP is a hydrosolubilizing group;
as well as their physiologically acceptable salts, solvates, or hydrates. The invention also provides intermediates for the synthesis thereof and detection methods employing them.
本发明提供了式 (I) 的探针:
其中
X1═NH、O 或 S;X2═O 或 S;SE 为易变基团,在刺激物的作用下可被消除,刺激物尤其可能是酶的存在、化合物或探针所在介质的物理化学特性;R 代表氢原子或-(L)n-GP,其中 n 等于 0 或 1,L 是连接臂,GP 是水溶性基团;
以及它们生理上可接受的盐、溶液或水合物。本发明还提供了用于合成它们的中间体以及使用它们的检测方法。
