• Functionalization of polyglycolides by "click" chemistry

  Poly(glycolide) polymers are disclosed. The polymers generally include a polymerized alkynyl-substituted glycolide having a polymer backbone with one or more alkynyl groups appended thereto. The alkynyl groups provide reactive sites for further functionalization of the polymer, for example by reaction with azide derivatives (e.g., azide-substituted organic compounds). Alkynyl and azide groups react via the “click” chemistry mechanism to form functional groups covalently bonded to the polymer via a triazole link. The polymers are biodegradable and can be used to deliver drugs or other therapeutic substances (e.g., large biomolecules such as single strand RNA) at targeted locations in a patient's body and/or at controlled release rates.

  本文披露了聚乙二醇酸酯聚合物。这些聚合物通常包括聚合的炔基取代的乙二醇酸酯，其聚合骨架上附有一个或多个炔基基团。炔基基团提供了进一步功能化聚合物的反应位点，例如通过与偶氮衍生物（例如偶氮基取代的有机化合物）反应。炔基和偶氮基通过“点击”化学机制反应，形成通过三唑键共价结合到聚合物上的功能基团。这些聚合物可生物降解，并可用于在患者体内的特定位置和/或受控释放速率下传递药物或其他治疗物质（例如单链RNA等大分子生物分子）。
