Branched molecular scaffolds are provided which are capable of linking two polymer residues (derived, for example, from polyethylene glycol) to two, three or four residues derived from biologically active molecules (e.g. from whole antibodies or from functionally active fragments or derivatives thereof), the latter being attached to the scaffold by means of hydrolytically stable linkages.
提供了分支分子支架,其能够将两个聚合物残基(例如来自聚乙二醇)连接到两个、三个或四个来自生物活性分子(例如来自整个抗体或其功能性活性片段或衍生物)的残基上,后者通过水解稳定键与支架相连。
