Macromolecular complexes which comprise a first and a second macromolecular moiety joined by a link derived from a linking agent having two or more reactive groups, one of these reactive groups being an activated acyl group, an isocyanate, an isothiocyanate, an iminoether, an iminothioether or an activated halogen atom attached to an aromatic ring and being capable of reacting with one of the macromolecules from which the macromolecular moieties are derived, under conditions where the remaining reactive group, or groups which is or are each an aziridine ring, an aryl azido group or a halogen atom in an a-position relative to a carbonyl group or two carbon atoms removed from a heteroatom carrying a lone pair of electrons, is or are substantially unreactive.
Methods are provided for making the complexes and so are uses for the complexes. Pharmaceutical formulations containing the complex as are provided.
大分子复合物,它由第一和第二大分子分子组成,第一和第二大分子分子通过由具有两个或两个以上反应性基团的连接剂产生的连接而连接在一起,这些反应性基团中的一个是活化酰基、异氰酸酯、异硫氰酸酯、亚胺醚、亚胺硫醚或连接到芳香环上的活化卤原子,并能与大分子分子衍生的大分子之一发生反应、在剩余的反应基团是或基本上不反应的条件下,这些基团是或基本上是氮丙啶环、芳基叠氮基团或相对于羰基的 a 位上的卤原子或从携带孤对电子的杂原子移开的两个碳原子上的卤原子。
提供了制造络合物的方法,也提供了络合物的用途。还提供了含有上述络合物的药物制剂。
