摘要:
The invention relates to the probes of formula (I); in which: X 1 = NH, O or S; X 2 = O or S; SE is a labile group, which may be removed under the action of a stimulus which may in particular be the presence of an enzyme, of a chemical compound or of a physicochemical characteristic of the medium containing the probe; A is an aromatic group, which, after cleavage of the C(X 2 )-O, linkage in aqueous solution, results in the release of a chomophore or a flurophore; R is a hydrogen atom or -(L)n-GP, in which n is equal to 0 or 1, L is a link arm, GP is a hydrosolubilizing group, and also the physiologically acceptable salts, solvates or hydrates thereof. The subject matter of the invention is also the intermediates for the synthesis thereof and the detection methods using same.
摘要:
The invention concerns novel glycosidase substrates of formula (I); in which R 0 , R 1 , R 2 , R 3 and R 4 are as defined in claim 1, and a method for detecting the presence of a catalytically active glycosidase by means of one of said substrates.
摘要:
The invention relates to contrast agents for magnetic resonance imaging, comprising a chelating ligand and a transition metal ion, said ligand bearing a substituent that can react chemically or biochemically with a target substance, thereby causing a spin state change.

as defined in Claim 1, which may be fully reversibly interconverted between non-tubulin-binding trans and tubulin-binding as isomeric forms, either by irradiation or spontaneously. The invention also concerns compounds with a azoaryl structure for use in studying the cytoskeleton and/or its associated processes, or in the treatment of a disease for which a tubulin polymerisation inhibition activity has a beneficial effect, wherein the compound is administered to the cell, organism or patient in need of such treatment in the trans form of the diazenyl bond, and where this trans form is inactive as regards a tubulin polymerisation inhibition effect, and where after photoisomerisation in vitro, in cellulo or in vivo to an azoaryl compound in its cis isomeric form of the diazenyl bond by the application of light, optionally with modification in vitro, in cellulo or in vivo of one or more substituents, the resultant cis form is active as regards a tubulin polymerisation inhibition effect.
