(FR) COMPOSÉS COMPRENANT UN LIEUR CLIVABLE ET LEURS UTILISATIONS
Abstract
(EN)
Provided are a compound including a cleavable linker, a use thereof, and an intermediate compound for preparing the same, and more particularly, the compound including a cleavable linker of the present invention may include an active agent (for example, a drug, a toxin, a ligand, a probe for detection, etc.) having a specific function or activity, a -S(=0)(=N-)- functional group which is capable of selectively releasing the active agent, and a functional group which triggers a chemical reaction, a physicochemical reaction and/or a biological reaction by external stimulation, and may further include a ligand (for example, oligopeptide, polypeptide, antibody, etc.) having binding specificity for a desired target receptor.
(FR)
L'invention concerne un composé comprenant un lieur clivable, son utilisation, et un composé intermédiaire pour sa préparation, et plus particulièrement, le composé comprenant un lieur clivable de la présente invention peut comprendre un agent actif (par exemple, un médicament, une toxine, un ligand, une sonde de détection, etc.) ayant une fonction ou une activité spécifique, un groupe fonctionnel a-S(=0 (= N-)- qui est capable de libérer sélectivement l'agent actif, et un groupe fonctionnel qui déclenche une réaction chimique, une réaction physico-chimique et/ou une réaction biologique par stimulation externe, et peut en outre comprendre un ligand (par exemple, un oligopeptide, un polypeptide, un anticorps, etc.) ayant une spécificité de liaison pour un récepteur cible souhaité.
