This invention relates to novel compositions comprising analogs of naturally occurring polypeptides, wherein the analog comprises an α-amino acid and at least one β-amino acid. Administration of the compositions may be used for effecting treatment or prevention of a plurality of disease states caused by dysfunctional biochemical or biological pathways. The compositions and methods of this invention are particularly useful to identify novel therapeutic modulators of in-vivo receptor activity with extended half-lives and relevant bioactivity as compared to the naturally translated polypeptides upon which the analogs are derived.
本发明涉及由天然
多肽类似物组成的新型组合物,其中类似物包括一种
