Abstract
(EN) A bifunctional chelating agent of the formula (I): wherein the variables R1, R1' , Q1, Q2 and M are as defined in the description of the present application. Also described is a complex of the above chelating agent to an ion of a stable or radioactive metal; a conjugate of the complex covalently attached to a biological carrier; and a pharmaceutical composition containing the conjugate.
(FR) La présente invention concerne un agent chélateur bifonctionnel de formule (I) : dans laquelle les variables R1, R1' , Q1, Q2 et M sont telles que définies dans la description de la présente demande. La présente invention concerne en outre un complexe de l'agent chélateur ci-dessus avec un ion d'un métal stable ou radioactif; un conjugué du complexe lié de façon covalente à un support biologique; et une composition pharmaceutique contenant le conjugué.
