    摘要: Prodrug formulations of insulin and insulin analogs are provided wherein the insulin peptide has been modified by an amide bond linkage of a dipeptide prodrug element. The prodrugs disclosed herein have extended half lives of at least 10 hours, and more typically greater than 2 hours, 20 hours and less than 70 hours, and are converted to the active form at physiological conditions through a non-enzymatic reaction driven by chemical instability.

    摘要: A non-enzymatically self cleaving dipeptide element is provided that can be linked to known medicinal agents via an amide bond. The dipeptide will spontaneously be cleaved from the medicinal agent under physiological conditions through a reaction driven by chemical instability. Accordingly, the dipeptide element provides a means of linking various compounds to known medicinal agents wherein the compounds are subsequently released from the medicinal agent after a predetermined time of exposure to physiological conditions. For example, the dipeptide can be linked to an active site of a drug to form a prodrug and/or the dipeptide may comprise a depot polymer to sequester an injectable composition comprising the complex at the point of administration.
