A mixture of conjugates in which each conjugate in the mixture comprises a calcitonin drug coupled to an oligomer that includes a polyalkylene glycol moiety is disclosed. The mixture may lower serum calcium levels in a subject by 10, 15 or even 20 percent or more. Moreover, the mixture may be more effective at surviving an in vitro model of intestinal digestion than non-conjugated calcitonin. Furthermore, the mixture may exhibit a higher bioavailability than non-conjugated calcitonin.
本文披露了一种混合物,其中混合物中的每个共轭物包括与包含聚乙二醇基团的寡聚物偶联的降钙素药物。该混合物可能通过10%、15%甚至20%或更多来降低受试者的血清钙水平。此外,该混合物可能比非共轭的降钙素更有效地在体外模拟的肠道消化模型中存活。此外,该混合物可能表现出比非共轭的降钙素更高的生物利用度。
