  Conjugates comprising a lipid or a hydrophilic polymer, such as polyethyleneglycol, linked to a ligand derived from an amine- or hydroxyl-containing compound, such as a drug or protein, are stable under conditions of storage, and are cleavable under mild thiolytic conditions to regenerate the amine- or hydroxyl-containing compound in its native form, without the formation of undesirable side products.

  包含脂质或亲水性聚合物的共轭物，例如聚乙二醇，与源自胺基或羟基含有化合物的配体相连，例如药物或蛋白质，在储存条件下稳定，并且在温和的硫醚条件下可被裂解，以使胺基或羟基含有化合物以其天然形式再生，而不形成不良副产物。
