    • The present invention relates to a method for preparaing a conjugate of a physiologically active polypeptide and a non-peptide polymer by linking physiologically active polypeptide with non-peptide polymer through a covalent bond using an organic solvent, and for preparing a physiologically active polypeptide complex by linking the conjugate with a carrier, in order to improve in vivo duration and stability of the physiologically active polypeptide. The method of the present invention can prepare the conjugate of the physiologically active polypeptide and non-peptide polymer with high purity and yield, and the physiologically active polypeptide complexes as prepared taking advantage of this can provide a reduction in production cost, and an extension of in vivo activity at a relatively high level and significantly increase in the blood half-life, and thus can be effectively used for development of the sustained-release formulation of physiologically active polypeptide which can raise patient's adaptability of taking the drug.
    • 本发明涉及一种制备生理活性多肽和非肽聚合物的缀合物的方法,其通过使用有机溶剂通过共价键连接生理活性多肽与非肽聚合物,并通过以下方式制备生理活性多肽复合物: 将缀合物与载体连接,以改善生理活性多肽的体内持续时间和稳定性。 本发明的方法可以制备具有高纯度和产率的生理活性多肽和非肽聚合物的缀合物,并且利用其制备的生理活性多肽复合物可以降低生产成本,并且延长 体内活性较高,血液半衰期显着增加,因此可有效用于开发生理活性多肽的缓释制剂,可提高患者服用药物的适应性。
