    • A method for the “one-pot” synthesis of insulin derivatives wherein insulin is modified at the &agr;-amino group of the PheB1 residue is described. The method comprises protecting the &agr;-amino group of the GlyA1 residue and the &egr;-amino group of the LysB29 residue by reaction of insulin with a cyclic anhydride of a dicarboxylic acid in the presence of a tertiary amine. The protected insulin is then reacted with an activated hydrophilic compound, preferably an activated polyethylene glycol, resulting in a conjugate of the hydrophilic compound coupled to the PheB1 residue of insulin. The protecting groups are then removed from the conjugate under mild acidic conditions, and the resulting insulin derivative can be purified by conventional methods. Monosubstituted insulin derivatives wherein polyethylene glycol or derivatives thereof or glycosides are coupled to the PheB1 residue of insulin are also described.
    • 描述了在PheB1残基的α-氨基处修饰胰岛素的“一锅”合成胰岛素衍生物的方法。 该方法包括在叔胺存在下,通过胰岛素与二羧酸的环状酸酐的反应来保护GlyA1残基的α-氨基和LysB29残基的ε-氨基。 然后将受保护的胰岛素与活化的亲水化合物,优选活化的聚乙二醇反应,得到与胰岛素的PheB1残基偶联的亲水性化合物的缀合物。 然后在温和的酸性条件下将保护基团从缀合物中除去,所得到的胰岛素衍生物可以通过常规方法纯化。 还描述了其中聚乙二醇或其衍生物或糖苷偶联至胰岛素的PheB1残基的单取代胰岛素衍生物。
