This invention pertains generally to valency molecules, such as valency platform molecules which act as scaffolds to which one or more molecules may be covalently tethered to form a conjugate. More particularly, the present invention pertains to valency platform molecules which comprise a carbamate linkage (i.e., -O-C(=O)-N~). In one aspect, the present invention pertains to valency platforms comprising carbamate linkages, which molecules have the structure of any one of Formulae I, II, or III, shown in Figure (1). In one aspect, the present invention pertains to valency platforms comprising carbamate linkages, which molecules have the structure of any one of Formulae IV, V, or VI, shown in Figure (8). The present invention also pertains to methods of preparing such valency platform molecules, conjugates comprising such valency platform molecules, and methods of preparing such conjugates.
La présente invention concerne, de façon générale, des molécules de valences, telles que les molécules à plate-forme de valence servant d'échafaudages auxquelles une ou plusieurs molécules peuvent se lier de manière covalente pour former un conjugué. L'invention concerne notamment des molécules à plate-forme de valenceomprenant une liaison carbamate (-O-C(=O)(N~). Dans un mode de réalisation, l'invention concerne des plates-formes de valence comportant des liaisons carbamate dont les molécules ont une structure de formule I, II ou III, comme d'après la figure 1. Dans un autre mode de réalisation l'invention concerne des plates-formes de valence comportant des liaisons carbamate dont les molécules ont une structure de formule IV, V ou VI, comme d'après la figure 8. Cette invention concerne également des procédés de préparation de telles molécules à plate-forme de valence, des conjugués comportant de telles molécules, et des procédés de préparation desdits conjugués.
