A series of new biodegradable copolymers and copolyanhydrides built of trimers of fumaric and succinic acid and propylene glycol, covering a wide range of compositions, were prepared and characterized for use as drug carriers. The polymers were found to degrade within a period of weeks. Polyanhydrides loaded with ibuprofen as a model drug released the drug for a period of one week, while the polyesters
制备了一系列由富马酸,琥珀酸和丙二醇的三聚体构成的新的可生物降解的共聚物和共聚酸酐,其涵盖了广泛的组成范围,并被表征用作药物载体。发现聚合物在数周内降解。载有布洛芬作为模型药物的聚酐将药物释放持续一周,而聚酯则将药物释放持续30天以上。在大鼠中研究了富马酸和琥珀酸基于三聚体的聚合物的生物相容性和排空速率。当植入小鼠体内时,发现所有聚合物都是相容的。
