A non-polydispersed mixture of conjugates in which each conjugate in the mixture comprises a drug coupled to an oligomer that includes a polyalkylene glycol moiety is disclosed. The mixture may exhibit higher in vivo activity than a polydispersed mixture of similar conjugates. The mixture may be more effective at surviving an in vitro model of intestinal digestion than polydispersed mixtures of similar conjugates. The mixture may result in less inter-subject variability than polydispersed mixtures of similar conjugates.
本发明揭示了一种非多分散混合物,其中混合物中的每个共轭物都包括一个药物偶联到一个包含聚
乙二醇基团的寡聚物。该混合物可能表现出比类似共轭物的多分散混合物更高的体内活性。该混合物可能比类似共轭物的多分散混合物更有效地在体外肠消化模型中存活。该混合物可能导致比类似共轭物的多分散混合物更少的受试者间变异性。
