Materials (e.g., particles, hydrogels) that provide extended release of one or more therapeutic agents are useful platforms for drug delivery. In part, the present invention relates to new triblock (ABC) bottlebrush copolymers which can be used in the formulation of particles and hydrogels for the extended release of therapeutic agents. In certain embodiments, the triblock bottlebrush copolymers, particles, and hydrogels described herein are thermally-responsive and gel at physiological temperature (e.g., upon administration to a subject), providing injectable and/or implantable gels which can be used for extended release drug delivery. The present invention also provides methods for extended release drug delivery, and methods of treating and/or preventing a disease or conditions in a subject, using the inventive copolymers, particles, and hydrogels. In addition, the present invention provides methods of preparing the triblock bottlebrush copolymers described herein.
提供延长一个或多个治疗剂释放的材料(例如,颗粒、水凝胶)是药物传递的有用平台。在某种程度上,本发明涉及可用于制备颗粒和水凝胶以延长治疗剂释放的新三嵌段(ABC)瓶刷共聚物。在某些实施例中,本文描述的三嵌段瓶刷共聚物、颗粒和水凝胶对温度敏感,并在生理温度下凝胶(例如,在给予受试者后),提供可用于延长释放药物传递的可注射和/或可植入凝胶。本发明还提供了延长释放药物传递的方法,以及使用创新共聚物、颗粒和水凝胶治疗和/或预防受试者疾病或症状的方法。此外,本发明提供了制备本文描述的三嵌段瓶刷共聚物的方法。
