Site-specific insulin conjugate

摘要

The present invention relates to: an insulin conjugate, wherein a non-peptidic polymer and an immunoglobulin Fc region are site-selectively connected, by a covalent bond, to an amino acid residue of a region excluding the N terminal of insulin &bgr; chain, and thus the binding force to an insulin receptor is improved, thereby increasing activity; an extended release preparation containing the same; and a method for preparing the same. The insulin conjugate of the present invention can provide an insulin preparation with remarkably improved
