Abstract: Peptide sequences capable of binding to insulin and/or insulin-like growth factor receptors with either agonist or antagonist activity and identified from various peptide libraries are disclosed. This invention also identifies at least two different binding sites, which are present on insulin and insulin-like growth factor receptors, and which selectively bind the peptides of this invention. As agonists, certain of the peptides of this invention may be useful for development as therapeutics to supplement or replace endogenous peptide hormones. The antagonists may also be developed as therapeutics.

Abstract: Insulin derivatives having a built-in glucose sensor, capable of delivering insulin from a depot as a function of the glucose concentration in the surrounding medium (e.g. tissue), such that the rate of insulin release from the depot increases with an increased glucose concentration and decreases with a decreased glucose concentration.
