Abstract
Cette invention a trait à des complexes d'actinium-225 (?225¿Ac) possédant des chelatants fonctionnalisés correspondant à la formule (I). Dans cette formule, chaque Q représente, de manière indépendante, un hydrogène ou (CHR?5¿)¿p?CO¿2?R, Q?1¿ représente un hydrogène ou (CHR?5¿)¿w?CO¿2?R, chaque R représente, de manière indépendante, un hydrogène, un benzyle ou un alkyle porteur de 1 à 4 atomes de carbone, à la condition qu'au moins deux éléments formés par la somme de Q et de Q?1¿ représentent un autre atome que celui de l'hydrogène, chaque R?5¿ représente, de manière indépendante un hydrogène, un alkyle porteur de 1 à 4 atomes de carbone ou un (C¿1?-C¿2? alkyl)phényle, X et Y représentent, chacun de manière indépendante, un hydrogène ou peuvent, pris avec un X et un Y adjacents, former une liaison supplémentaire carbone-carbone, la valeur de n est 0 ou 1, m représente un nombre entier dont la valeur est comprise entre 0 et 10 inclus, la valeur de p est 1 ou 2, celle de r est 0 ou 1, celle de w est 0 ou 1, à la condition que la valeur de n ne soit que 1 lorsque X et/ou Y constituent une liaison supplémentaire carbone-carbone et que la somme de r et de w s'échelonne entre 0 et 1, L représente un groupe lieur/séparateur lié de façon covalente à un atome d'hydrogène de l'un des atomes de carbone auquel il est relié et remplace celui-ci, ce groupe lieur/séparateur correspondant à la formule (1), dans laquelle S représente un nombre entier d'une valeur s'échelonnant de 0 à 1, t représente un nombre entier d'une valeur s'échelonnant de 0 à 20 inclus, R?1¿ représente un fragment électrophile ou nucléophile permettant un rattachement covalent à un anticorps ou à un fragment de celui-ci ou bien un lieur de synthèse pouvant être rattaché à un anticorps ou à un fragment ou à un précurseur de celui-ci, Cyc représente un fragment aliphatique cyclique, un fragment aromatique, un fragment aliphatique hétérocyclique ou un fragment aromatique hétérocyclique, chacun desdits fragments étant éventuellement substitués par un ou plusieurs groupes n'interférant pas avec la liaison à un anticorps ou à un fragment d'anticorps, à la condition que, lorsque la valeur de s, t, m, r, et de n est 0, R?1¿ représente autre chose qu'un carboxyle. Cette invention, qui porte également sur les sels acceptables du point de vue pharmaceutique, ainsi que sur les conjugats de ces complexes, concerne, de surcroît, l'utilisation qui en est faite en matière de radio-immunothérapie.
