This invention provides a method of modifying a cellular response in a mammal. The method comprises administering to the mammal an effective amount of biodegradable nanoparticles, each of said nanoparticles comprising an active agent, a biodegradable polymer, and a bone targeting agent administering to a mammal an effective amount of a composition comprising a compound absorbed in a biodegradable nanoparticle which is attached to a bone targeting agent. The invention also provides a method for modifying a cellular response in a mammalian cell comprising contacting the mammalian cell with biodegradable nanoparticles. The invention further provides a method of delivering an exogenous substance to a mammal. The method comprises administering to the mammal a composition comprising the exogenous substance absorbed into a biodegradable nanoparticle, wherein the biodegradable nanoparticle is covalently attached to a bone targeting agent. The invention also provides a composition and a process for preparing the composition comprising a biologically active or therapeutic agent of compound, a biodegradable nanoparticle, and a bone targeting agent.
本发明提供了一种修改哺乳动物细胞反应的方法。该方法包括向哺乳动物施用有效量的可生物降解纳米颗粒,其中每个纳米颗粒包括活性剂、可生物降解聚合物和骨靶向剂。本发明还提供了一种在哺乳动物细胞中修改细胞反应的方法,包括将可生物降解纳米颗粒与哺乳动物细胞接触。本发明进一步提供了一种将外源物质输送到哺乳动物体内的方法。该方法包括向哺乳动物施用一种组合物,该组合物包括外源物质吸附到可生物降解纳米颗粒中,其中可生物降解纳米颗粒与骨靶向剂共价结合。本发明还提供了一种组合物及其制备方法,该组合物包括生物活性或治疗剂的化合物、可生物降解纳米颗粒和骨靶向剂。
