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 FIG.

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 FIG.
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.
本发明涉及价态分子,例如作为支架的价态平台分子,可以将一个或多个分子共价地连接在一起形成一个共轭物。更具体地说,本发明涉及包含碳酸酯键(即,—O—C(═O)—N<)的价态平台分子。在一个方面,本发明涉及包含碳酸酯键的价态平台,这些分子具有在图1中显示的任一公式I、II或III的结构。在另一个方面,本发明涉及包含碳酸酯键的价态平台,这些分子具有在图8中显示的任一公式IV、V或VI的结构。本发明还涉及制备这种价态平台分子、包含这种价态平台分子的共轭物以及制备这种共轭物的方法。
