    • Polymers and compositions, collectively “bioadhesive materials”, with improved bioadhesive properties have been developed. One or more compounds comprising: a) an aromatic moiety comprising two or more hydroxyl substituents, methoxy substituents, substituents hydrolyzable to hydroxyl substituents, or a combination thereof, and b) a primary or secondary amino moiety are either covalently attached to a polymer or are physically mixed with a polymer to form a bioadhesive material. These bioadhesive materials can be used, for example, to fabricate new drug delivery or diagnostic systems with increased residence time at tissue surfaces, and consequently increase the bioavailability of a drug or a diagnostic agent.
    • 已经开发了具有改善的生物粘合性质的聚合物和组合物,统称为“生物粘附材料”。 一种或多种化合物,其包含:a)包含两个或更多个羟基取代基的芳族部分,甲氧基取代基,可羟基取代基可水解的取代基,或其组合,和b)伯或仲氨基部分共价连接至聚合物或 与聚合物物理混合以形成生物粘附材料。 这些生物粘附材料可以用于例如制备新的药物递送或诊断系统,其在组织表面上的停留时间增加,从而提高药物或诊断剂的生物利用度。
