A composition comprising an amphiphilic polymeric material that is both hydrogen peroxide- and hypoxia-sensitive is described. The composition can further include a glucose-oxidizing enzyme and insulin, a bioactive derivative thereof, and/or another therapeutic agent (e.g., another diabetes treatment agent). The polymeric material can form vesicles that comprise single or multiple layers of the polymeric material that enclose the glucose-oxidizing enzyme and the insulin, bioactive derivative and/or other therapeutic agent. The vesicles can be loaded into microneedles to, for example, prepare microneedle arrays for skin patches. Methods of delivering insulin to a subject using the compositions, vesicles, microneedles, and/or microneedle array skin patches are also described.
本文描述了一种由对过氧化氢和缺氧敏感的两性聚合物材料组成的组合物。该组合物可进一步包括葡萄糖氧化酶和胰岛素、其生物活性衍生物和/或另一种治疗剂(如另一种糖尿病治疗剂)。聚合材料可形成囊泡,囊泡由单层或多层聚合材料组成,包覆葡萄糖氧化酶和胰岛素、生物活性衍生物和/或其他治疗剂。囊泡可装入微针,例如,制备用于皮肤贴片的微针阵列。还描述了使用组合物、囊泡、微针和/或微针阵列皮肤贴片向受试者输送胰岛素的方法。
