Novel cyclic peptides, cyclic peptide conjugates and compositions containing them for treating neurological diseases in a subject include an Odorranalectin (OL) sequence or modified OL sequence as a scaffold and a biologically active peptide or protein and/or therapeutic agent conjugated thereto. Methods of treatment of neurological diseases are based on intranasal delivery of a cyclic peptide or cyclic peptide conjugate as described herein. Combinatorial libraries that include a plurality of cyclic peptides have also been developed and can be used to screen for a ligand(s) for a receptor of interest.

The present disclosure describes novel peptides, including peptides that inhibit the proteolytic activity of insulin-de-grading enzyme (IDE). Also described are cosmetic and pharmaceutical formulations including these peptides, as well as a treatment method aimed at improving the appearance and/or texture of skin and/or promoting wound healing and a method for treating diabetes. The disclosed peptides and formulations are particularly useful for addressing the problem of impaired wound healing in diabetes.
